Rechargeable lithium ion / poly cells are not classified (to shippers) as containing lithium metal. Here's a small word of warning regarding lithium thionyl chloride primary cells, which are classified as containing lithium metal: if you take one apart, (which I think you might like to) do it with good ventilation on hand - like maybe outside - and really, really don't breathe the fumes close-up. They are very unpleasant and will cause you lasting pain if they get in your face. Taking these cells apart produces good heat and fumes etc, so would no doubt be enjoyable and I don't want to dissuade you. Just don't wait for the stink before going to open the window.
Of all the people I've come across who have a Patreon, Clive, you are the most humble. Happy to support. I'm looking forward to his Chinese disco lamp! PARTY TIME!!!
+Edward Jones indeed handled the best way ive seen it done, plus his stated targets are at least reasonably humble and not intending to change the channel too much
binge watching your channel for 3 days has just inspired me to pick up my cheapy soldering iron and solder and use them as they are intended for the first time EVER. I just de-soldered an LED n resistor from a fake car ozone plug and reconnected them together with just solder...grabbed a battery and some alligator leads and it works! ...n I did "practice" soldering on the shit board they came off of and, your RIGHT, it's EASY ....n FUN! I did as you said...heat the hole/component, then apply solder flow, remove solder wire first then the soldering iron tip and it looks BETTER than the factory solder joints on the board! PERFECT Hershey kisses! ...THANKS man...I prob just found a hobby I might stick with...I just wish I could cram all your knowledge in my brain with an instant download somehow! ...keep the vids coming! ...n thanks for the inspiration to pick up that iron after it's been busy sitting there as a "unicorn tool" in the darkness for a decade. GREAT channel BTW! thank YOU...when I get some cash I'll head over to buy you a "cookie n coffee." ...n I don't typically follow through on donate links...BUT you deserve it! ...more TH-camrs like you n I'd REALLY be broke lol. THANKS AGAIN and keep em coming Clive!
MyBigThing2010 If you have an iron thats worth a damn that can take good tips like Hakko or another premium brand, there are some awesome ones. Hakko has a bent tip and a knife tip that are surprisingly amazing for soldering, and a medium-sized chisel tip will be a lot better than the pointy tip most irons come with by default. Also, get a flux pen and solder braid (wick). That shit is magical.
Mark Dowd all been purchased (because of Clive) since I originally posted....except for a decent iron...I'm prob gonna buy a cheap Chinese knock off with hot air and the iron pelt for financial reasons..I did buy the usb iron and was surprised how well it worked...built 3 kits with that one and Chinese eBay solder and everything actually worked and didn't catch fire...I'm satisfied for the moment until I mentally decide on which 2in1 solder station I want to buy....still need a power supply too...time and begging for change with a coffee can will tell ;)
in regards to Patreon, I have an ad-blocker and you have taught me a hell of a lot so $5 is very little to pay for the on going ramble of your destructive/reconstructive pass time.
I've got to thank you Clive for going ahead and filming what you do - as a student electrical engineer it's been so useful to pick up general information on power supplies, general product quality etc, and what mistakes not to make in a design career! So, thank you!
Clive, you are very much like me, I love pulling things apart & seeing what's inside except when I do it, they never seem to work again LOL. Thanks for the great videos.
I actually talked to Bob Dremel once to get advice on how to fix a really early motor/grinder. He was retired in Palm Springs but still wanted to help me repair the speed control because it was one of the first production models ever made. Super nice guy.
I bought two of those 10W flood lights and I'm really excited to see the warm white color. Since it's running such cool, I could use it inside my car while I'm working on the interior etc. which is great.
this is just a great video clive. it actually feels like we are just hanging out at your house like old buddies. i like all your vids, but tis one feels like home man.
+bigclivedotcom , sodium fun stuff, back in the day (80's) before everyone got so serious, a mate and myself, relived our high school science lab of a 5kg brick of sodium and threw it in a local lake, which was mega levels of very stupid and dangerous. which directly translated into mega levels of fun.
Don't know where you went to school, but no school lab in the UK would ever have that amount of sodium in stock. More likely they might have less than 100g. How do I know, well thirty years working in school science education, including being a safety adviser and consultant. You do realise that a 5kg block of sodium would be in excess of 500cm3.
Howdy, I built myself one of those little spot lights for use in our motor home, when working on it. Ask anyone who lives in one and they will tell you that you are constantly working on them. I have it hooked up to 6 18650's in a case then added a 12 volt 20 watt LED with bubbble lense and on the side I put an amp/volt meter. Switches control both the meter and the light, and the plugs for the probes are on the top. It has proved itself very valuable on our Winter in Arizona and was much admired by those who did any work on my unit when I offered her up for duty in the repair processes.
Your videos inspired me to make my own electronic workbench and thanks to a tax favour in my direction, I was able to spend around $800.00 on tools and DIY projects for soldering practise and troubleshooting when they fail, stuff starts arriving on the 16th I am so excited. 🤷♂️😁🤣
I nearly blew up my science class room as a wee boy with Sodium. The teacher said "now you only need to cut off an 2mm sliver and place it in the water tank. I cut of 2 inches and with a grin put in the water...well poor Sarah Smith wet herself and the classroom was evacuated. Naughty me.
Chemisty time: In lithium batteries the lithium is bound up with another or other element(s), (Cobalt, manganese, iron, phosphorous, alumin[i]um, and/or titanium)depending on type. Why didn't it react? Same reason you don't chlorinate yourself while your intestines explode when you have salty fries (or "chips" depending on your regional dialect) Salt is Sodium chloride (NaCl) after all. You can liberate the chlorine and the sodium by breaking the molecular bonds, but your intestines are smarter than just leaving elemental chlorine and elemental sodium laying around: They safely bind them up in ways that make them usable by later biochemical reactions.
Clive: I like the grouping the different things together into a half hour video. No need to split them all up when you're putting them all out at the same time anyways :)
zaprodk yep, it's usually either lithium cobalt oxide or lithium manganese oxide or a similar compound. The reason for that is that the cobalt/manganese oxides form a sort of scaffolding that the lithium ions can move into and out of as you discharge and charge the battery. That way the volume of the cathode stays constant throughout cycling and the battery doesn't swell. The anode (whether graphite or polymer) is also structured such that it has room for the ions for the same reason.
One recommendation for discharging LiPo batteries is to put them in water. So once battery is drained place it in water preferably with salt and wait for the bubbling to stop. Then dispose of it. The salt water method has many haters as well. I can look up the links on this info if you want.
+Rav Gupta I'm of the haters. LOL. In my testing I have found that salt water usually just causes the internal leads and pads to dissolve due to galvanic corrosion. So, the battery may read 0 volts but there is still power in the cells. (I am referring mainly to RC car type LiPos with 2 or more cells.)
In my teens I worked out how to make my own sodium in the kitchen. When I got a grape sized lump I threw it in a sink full of water where it fizzed and burned with a nice orange glow. All without the aid of googles, labcoat and gloves..
Every time BigClive™ says, "Don't worry, I have a Dremel" it makes me think of the old Range Rover commercials where one guy mentions a whole bunch of hazards and then the other guy says, "Don't worry, I have a Range Rover." Well in this case I can picture the viewers of the video saying, "But it's in a potted module" and Clive says, "Don't worry, I have a Dremel!"
I have to ask Clive, why do you so often use your most craptacular multimeters? I've seen that you have better ones, so wondered why you often chose terrible ones to use? (other than you saying that one was showing up so well) my m-830 equivalent was safely stored in the bin many years ago ;)
+arcadeuk The dinky meter always has a set of croc-clip leads, so it's handy for clipping onto things while the other meters are in use, or just as the nearest meter that comes to hand. It's biggest weakness is also its biggest advantage. The fact that you can select the uA and mA scales without swapping the leads.
At the end you are measuring the case of the IC not the junctions. The junctions are probably much hotter than than. The datasheet for this part (mc34063) says the thermal resistance of the plastic package is 100°C/W so with 100+°C on the outside of the chip you are probably pushing the junction temp way over 150°C but the current limiter kicks in.
+Michel PASTOR The thermal resistance in the datasheet is junction-to-ambient; junction-to-case WILL be lower, but you can bet that chip ain't exactly happy over there :)
The 0W rating is probably 150C, and intermittent soldering tolerance twice that, so it’s doing okay as long as the internal PTC keeps adding resistance.
I've seen a lot of lithium batterie melt down over the years, many of them involved jets of flames and smoke, so the tear down video of the battery made me nervous. That said, a smaller battery like this likely wouldn't be too catastrophic. I really wouldn't want to breathe those fumes, though. The reason you didn't get any reaction from the lithium in water is likely twofold. Once the lithium is exposed to air, especially while in a "charged state" it oxidizes very rapidly, protecting the surface from the water. I think you mentioned this idea. The second thought I have on this is that the lithium becomes fairly inert, once the cell is discharged. When I have a battery (lithium-polymer) that's reached the end of it useful life, I discharge it as far as possible, then leave it in a container of salt water, outdoors, for a few weeks. This makes the cell harmless and safe for disposal in a regular landfill.
Fascinates me that YT advertising is garbage for 99% of the creators (I was one for a short bit) due to all of the plugins to stop advertising, and dirty shenanigans by Google, yet we have an idiot on his channel making 12 million dollars a year (has over a billion subs). Glad he can do it at almost 26 years old but things that broaden your mind, instead of rotting it, just don't seem to pay the bills in life.
+legalizeshemp420 That's the peril of doing technical videos. Only the technical people will watch them. But that's fine by me, because technical people are my favourite type of people.
Agh, Clive. I know this video is old, but I'm sorry to hear about your mother. I'm staying home to help my father since my mom has become severely mentally disabled from a rare illness, I know that pain.
Modern cars like mine don't power the lighter socket when the engine is off. My old Fiat Punto and Tipo had a lighter socket that had live lighter sockets, my Punto Mk2 has a dead lighter socket when the engine is not running. I used to keep a 12V solar PV cell in both earlier versions of my cars to trickle the battery with charge to replace the charge being taken by the dash board clock. The Punto Mk2 has a digital LCD clock so the current draw is minimal. It is depending on the vehicle only possible to charge when the engine is running.
Whew, 150$/month already. Just proves that you do quality videos for a great community. Tried to become a patreon, but im a bit too young to verify my paypal account.
I DID - - I DID - - I Did go out and buy one of those sexy little LED Lights. It sits all by it's self on a shelf in the bedroom of our 36 foot Class A Motor Home which is (might I admit it) parked here in South Dakota in the midst of winter, when she is supposed to be parked down in Arizona! Damn I hate it when life gets in the way of FUN! At any rate, I had big plans for the little light but never got around to mounting her on my RV to assist in walking back from the club room late in the night after a few beers and lots of cheers from my fellow nomads!
The more you discharge a lipo, the safer it becomes. A fully charged lipo goes berserk. It was only a couple weeks ago a friend of mine breached a 6s 5ah 20C lipo. Thankfully only one of the pouches failed. But my word, dramatic noise and lots of very nasty smoke very very quickly. Finished off with a bit of a flame.
I think you weren't able to get the Lithium to react because Lithium-ion accumulators don't contain elemental Lithium. Only the non-rechargeable Lithium-batteries do, ifI remember right.
Great Video as usual! at 30:40 when you crank the little power supply up to 24V you can hear some high frequency tone sweeping up - is that some capacitor or the chip "working hard" - or maybe something else on your bench?
I used to do the reactions of sodium, lithium and potassium with water, the largest I ever used was about the size of a garden pea, more than enough toi be dramatic. More usually it was matchead size.
1:05 I am still hugely satisfied how my photocamera is still working after desperately wanting to learn how to swim (I got in an one-sided accident with my bike causing my camera to slip out of the bag in December 2015) in a typically Dutch "moddersloot" (muddy waterway). Within 24 hours of the accident I have placed it in the oven (an electrical one, gas would be problematic) in a huge bowl of rice and let it sit for 3 hours at 40 degrees Celsius while carefully monitoring the temperature every 10 minutes. The owner of the local photography shop is still absolutely baffled that the thing still works, because every camera with water damage he has seen stops working within 2 to 3 months of it coming into contact with water. After it came out of the oven the haze that had gotten into the LCD screen had disappeared, and I was able to fire the shutter at command again, instead of it firing like crazy randomly. A week ago I finally took the sand out of the lens that was on it during the accident and submerging, because at work has some pretty awesome tools for that and I managed to not only get the sand out (by removing every lens element), but I also got the lens back together, working AND as a bonus, got rid of a pretty awful color abberation at the bigger apertures! :)
What of screwdriver are you using in the video.. does your screwdriver set have a torx screw tri wing it has 3 Pronged and where did you buy them? Thanks😀
You get quite extensive kits of the precision drivers online. My usual one is from Poundland in the UK but you can also get 8 in 1 and 9 in 1 drivers online.
THose 12 volt car adapters seem to break quite often, usually because someone steps on them, I take the boards and use them to build an adapter to step a 12 volt 18650 pack down to 5 volts for a home built power brick.
Brand new disposable Lithium batteries are the best source for Lithium. Open case, unwrap the contents and put the Lithium under oil immediately or it will oxidise in a few tens of seconds.
Lithium metal oxidises extremely rapidly in air, in particular if it is wet. The thin layer on the electrodes would be totally reacted in less than a second.
you can take apart an energizer ultimate lithium battery (AA is easiest) to get pure lithium. But to get it to react you would have to put it into water as soon after you got it out as possible.
Fun video as always Clive! I'm curious if you think those little10 W lamps would be any good for ceiling mounted shop lighting? I'll be heading over to Patreon soon. Be well.
+Pedunculopontine I'd say the little ten watt lights are good for either low level area lighting like outdoors at night, or for extra light down close to a work bench, but probably the cold white for the extra perceived intensity, and maybe a few for extra intensity.
Tsk Clive, the voltage of a nominal 12v car system will be 14.4v when the engine is running. If it's as low as 13.8v, either the alternator is failing, or it's a very old car with a dynamo, and you have all the electrics switched on with the engine only idling ;)
wouldn't a boosting type of circuit help if you used a battery like alkalines because the voltage on them drops quite significantly which means you cant empty most of the cell when driving an led?
HEAT MAN.. Next time heat the potted device up.. The Epoxy turns soft and crumbly, making it way easy to tear down! You can use a small heat gun or put it in a toaster oven!
+Travis Wizniuk Yeah, I was fairly convinced it was just going to be a resistor. If I'd thought it was more I'd have used the heat gun to remove layers. I've even baked resin encased things in my oven to soften them up in the past.
Just an FYI.. I love you videos, but I was cringing the whole time as pieces were flying off! Maybe just my ODC.. I also have a suggestion for a light teardown. I just bought a Stanley FatMax Spotlight. You would love looking at the inside of that (full of surprises).
No its a handheld spotlight.. I know it looks pretty boring, but trust me its pretty neat inside.

+Mikey Peters Best I can tell - eBay, search for item# 111762785517 It's the seller mentioned in the prior video (hidtop), and they look to be right, but/and also available in various power configs/price.
Clive, your Flir camera can be patched to work exactly like higher resolution model. Search for the model number of your camera and find instructions for unlocking the kernel.
Hey, I don't know if you read my previous comments on your last video, but there I also told I could not get a reaction from the Lithium combined with water... It's kind of silly, but I guess they are using some kind of Lithium that is more stable. Oh, and here in the Netherlands you can buy Sodium Carbide 15 euros for 5 kilograms. So if you want to play, get over here! :)
Before experimenting with pure Na, your friend should have watched the Periodic Table of Videos videos on Na and H2O :-). Being covered in burning Na bits would then not be a surprise :-)
+bigclivedotcom mineral oil is used to prevent reactions wiith m water in the air with acali metals like sodium so that prevents the reaction we want however if oyu could figure a way to get the skin of oil that is on your lithium when you put it into the water that would work perhaps you could use something like galium? it doesnt wet like mineral oil does
bigclivedotcom actually the lithium material in these batteries doesn't contain much free metallic lithium. It's in the form of lithium cobalt oxide or lithium manganese oxide. Those compounds form a sort of scaffolding with the lithium ions loosely bonded so they can move into and out of it as you discharge and charge the battery. So cutting it under water or oil won't expose a significant amount of lithium atoms because theoretically all lithium in that battery should be in the form of ions. The bang you get from putting metallic lithium in water is due to it rapidly ionizing so if you start with lithium ions as in the case of these batteries there's no bang.
'Lithium ion batteries have zero metallic lithium in them. The flamability is mostly/all in the solvent based electrolyte.. Disposable lithium cells do have lithium (when they're fresh/not discharged), if you want to try to put some of it in water..
I liked that switchmode psu clive, simple but didnt have a nasty look, its a typical flyback supply (output on collapse of field), the chip sounds like one of those Top devices, although i dont like the power mosfet being inside the chip, i just dont lol :-D . I have one of those 830b meters by mastech, i applied a thick wire from the com terminal to the common pin of the i.c, the stray resistance dropped, and dump the nasty probe wires, resistance hell.
+zx8401ztv hehe, an 830b! asking for trouble! spend more than a quid next time, lol :P I let you off, a few years ago i bought one out of sheer curiosity about the amazing low price, of course the leads were trash right off, the sockets and then the casing let go, but it lasted a couple of years in my toolbox for light measuring, it actually remained perfectly accurate all along, build quality is the main issue, and anything with no fuse on 10a range im gonna kill anyway, lol
+jusb1066 ha ha :-D, now your not turning in to dave are you? lol. Ive been using cheap meters for 30 years and im not dead (i dont think so), and ive never had one explode :-D. Its how and what you use them for, ive had my old micronta digital reading 1000 volts when setting a psu on an old oscilliscope, it didnt go wrong or kill me, but im not daft... ok just a bit daft :), the meter was on a table and connected, then the power was switched on, i observed with eyes only he he :-D :-D The mastech only 830b is fine, as long as you know its limitations :-D But i do admit that the £2.00 non mastech ones just make me shudder lol.
zx8401ztv no indeed i still have my first dmm, a 'testlab' made in taiwan i bought in 1988 at tech college, its used as the first grab and lives in the garage now, but still works just fine, i dont own any flukes! (i admit i used to), heck my 'best' meter is a £10 uni-t that i think electron-update tested last year!
+jusb1066 ha ha Welcome to cheap test meters anonimus :-D Ok i have more than one 830b, the shame of admitting it :) I like the icl7106 adc that all the cheap meters were based on. My micronta 22-191 was bought from tandys in coventry a loooooong time ago for 80 quid, based on a seiko chip (didnt they make watches). It still works and i upgraded the reference resistors and calibrated it last year, a good old digital (i can hear dave puking lol ).
How about you tell us your PayPal account so we can just pay what we like? Also I have purchased 4 of those 10w led floodlights. Love all the videos. Keep making them even upload the more rambling or boring ones. Maybe create a second Chanel for those of us that like that sort of thing?
+bigclivedotcom Is the "potting compound" some kind of epoxy/resin or a thermosetting plastic/resin, if it's the latter maybe heating the potting compound may allow you to expose innards in future deconstructions.
+James Lamb It was a resin type material. I've used a heat gun and my oven to soften similar substances in the past. I was a bit more violent with this one because I was confident it was just a resistor inside.
If your ipad gets damaged, you can always try out some chinese android tablets hehe just like your mobile.....(After the Motorola)....some decently good quality ones would be ones made by the bigger Chinese companies if you dont wanna gamble. A backup tablet is always a good idea though right.... Like your "on standby" mobile backup. Great vids :)
Another video idea.... Would be to review cheap, affordable, decent quality chinese tablets and mobiles....say up to £100.... Just a thought.(Try looking at Wish)
Wouldn't that chip still have been hot from running at 24V ? Also, if a cigarette lighter socket is fitted to a 24 volt vehicle, i think it would still be 12V as it's connected to just one of the batteries. This means they could claim 'suitable for 12v or 24v vehicles', though as you proved, it will 'run' on 24v without going bang (for a short while anyway).
+Sparky Projects i think the more modern trucks do indeed supply 12v to the cab socket and people use normal car usb chargers for phones all the time, the older days of 20 years ago it was indeed 24v with the typical problem of trying to find anything that was 24v like a radio at the time, or fully insulating it from the ground/chassis was needed to do it with the 12v battery tap which was hard when you had an aerial to consider also
+jusb1066 When running a 12v item on a 24v vehicle system, you would connect to ground and the 12v point on the battery, did it a couple of times at work, no need for isolation, and this was probably 25+ years ago
+Sparky Projects A modest number of trucks do have 24V sockets. I made a truck driving friend a simple tester that indicated what voltage was present after he blew up several lighter socket power supplies.

Rambling is good Bigclive! Don't ever let anyone tell you otherwise. Also, I'm jealous of the thermal imaging camera! ;-)
*grabs mains led tightly* "this has so much potential!"
especially useful for ungrounded ones
That Sodium will be fun to play wit. Reminding you. Great videos BigClive. After your cake and cookies.
Your videos inspired me to make my own electronic workbench and thanks to a tax favour in my direction, I was able to spend around $800.00 on tools and DIY projects for soldering practise and troubleshooting when they fail, stuff starts arriving on the 16th I am so excited.
🤷♂️😁🤣
Hey man, the channel and the website is awesome. great to see simple easy to follow guides!
Although it makes sense, I had never thought about American "alligator" clips being called "crocodile" clips elsewhere. Interesting.
Canadian alligator clips...
I nearly blew up my science class room as a wee boy with Sodium. The teacher said "now you only need to cut off an 2mm sliver and place it in the water tank. I cut of 2 inches and with a grin put in the water...well poor Sarah Smith wet herself and the classroom was evacuated. Naughty me.
Oh well Phil, you got the two right at least, LOL. I've made worse mistakes than that but that was pretty funny.
Chemisty time: In lithium batteries the lithium is bound up with another or other element(s), (Cobalt, manganese, iron, phosphorous, alumin[i]um, and/or titanium)depending on type.
Why didn't it react? Same reason you don't chlorinate yourself while your intestines explode when you have salty fries (or "chips" depending on your regional dialect) Salt is Sodium chloride (NaCl) after all. You can liberate the chlorine and the sodium by breaking the molecular bonds, but your intestines are smarter than just leaving elemental chlorine and elemental sodium laying around: They safely bind them up in ways that make them usable by later biochemical reactions.
What's the [ ] round the "i" for?
In the USA, you normally say "aluminum", while in the EU you normally say "aluminIum"
Clive: I like the grouping the different things together into a half hour video. No need to split them all up when you're putting them all out at the same time anyways :)
AFAIK there is no metallic lithium in Lithium-ion batteries. Only Lithium-ions.
It isnt usually, but when a battery somehow manages to fail it can create elementary lithium.
+drkastenbrot the non rechargeable lithium batteries contain metallic lithium
zaprodk yep, it's usually either lithium cobalt oxide or lithium manganese oxide or a similar compound. The reason for that is that the cobalt/manganese oxides form a sort of scaffolding that the lithium ions can move into and out of as you discharge and charge the battery. That way the volume of the cathode stays constant throughout cycling and the battery doesn't swell. The anode (whether graphite or polymer) is also structured such that it has room for the ions for the same reason.
One recommendation for discharging LiPo batteries is to put them in water. So once battery is drained place it in water preferably with salt and wait for the bubbling to stop. Then dispose of it. The salt water method has many haters as well. I can look up the links on this info if you want.
+Rav Gupta I'm of the haters. LOL. In my testing I have found that salt water usually just causes the internal leads and pads to dissolve due to galvanic corrosion. So, the battery may read 0 volts but there is still power in the cells. (I am referring mainly to RC car type LiPos with 2 or more cells.)
Great video, didn't mind that it ran on for ages because it was fascinating.
I agree those snips are awesome, I think I have the same one in my electrical tool bags
Worth it
In my teens I worked out how to make my own sodium in the kitchen. When I got a grape sized lump I threw it in a sink full of water where it fizzed and burned with a nice orange glow. All without the aid of googles, labcoat and gloves..
Every time BigClive™ says, "Don't worry, I have a Dremel" it makes me think of the old Range Rover commercials where one guy mentions a whole bunch of hazards and then the other guy says, "Don't worry, I have a Range Rover." Well in this case I can picture the viewers of the video saying, "But it's in a potted module" and Clive says, "Don't worry, I have a Dremel!"
I have to ask Clive, why do you so often use your most craptacular multimeters? I've seen that you have better ones, so wondered why you often chose terrible ones to use? (other than you saying that one was showing up so well) my m-830 equivalent was safely stored in the bin many years ago ;)
+arcadeuk The dinky meter always has a set of croc-clip leads, so it's handy for clipping onto things while the other meters are in use, or just as the nearest meter that comes to hand. It's biggest weakness is also its biggest advantage. The fact that you can select the uA and mA scales without swapping the leads.
"I don't want it to go on any longer...it's HUGE!"
Sadly I have never heard this phrase before :(
At the end you are measuring the case of the IC not the junctions. The junctions are probably much hotter than than. The datasheet for this part (mc34063) says the thermal resistance of the plastic package is 100°C/W so with 100+°C on the outside of the chip you are probably pushing the junction temp way over 150°C but the current limiter kicks in.
+Michel PASTOR The thermal resistance in the datasheet is junction-to-ambient; junction-to-case WILL be lower, but you can bet that chip ain't exactly happy over there :)
The 0W rating is probably 150C, and intermittent soldering tolerance twice that, so it’s doing okay as long as the internal PTC keeps adding resistance.
I've seen a lot of lithium batterie melt down over the years, many of them involved jets of flames and smoke, so the tear down video of the battery made me nervous. That said, a smaller battery like this likely wouldn't be too catastrophic. I really wouldn't want to breathe those fumes, though.
The reason you didn't get any reaction from the lithium in water is likely twofold. Once the lithium is exposed to air, especially while in a "charged state" it oxidizes very rapidly, protecting the surface from the water. I think you mentioned this idea. The second thought I have on this is that the lithium becomes fairly inert, once the cell is discharged. When I have a battery (lithium-polymer) that's reached the end of it useful life, I discharge it as far as possible, then leave it in a container of salt water, outdoors, for a few weeks. This makes the cell harmless and safe for disposal in a regular landfill.
Rambley is fine. ;->
Fascinates me that YT advertising is garbage for 99% of the creators (I was one for a short bit) due to all of the plugins to stop advertising, and dirty shenanigans by Google, yet we have an idiot on his channel making 12 million dollars a year (has over a billion subs). Glad he can do it at almost 26 years old but things that broaden your mind, instead of rotting it, just don't seem to pay the bills in life.
+legalizeshemp420 seems to be the same thing for newspapers, magazines, current music even most tv shows, which i avoid all the above

If it is made to expand your mind, and to use a brain cell, it doesn't seem to make money or have much of a chance.
+legalizeshemp420 That's the peril of doing technical videos. Only the technical people will watch them. But that's fine by me, because technical people are my favourite type of people.
bigclivedotcom
Agreed, just wish dumb didn't pay off so well.
Agh, Clive. I know this video is old, but I'm sorry to hear about your mother.
I'm staying home to help my father since my mom has become severely mentally disabled from a rare illness, I know that pain.
Modern cars like mine don't power the lighter socket when the engine is off.
My old Fiat Punto and Tipo had a lighter socket that had live lighter sockets, my Punto Mk2 has a dead lighter socket when the engine is not running.
I used to keep a 12V solar PV cell in both earlier versions of my cars to trickle the battery with charge to replace the charge being taken by the dash board clock. The Punto Mk2 has a digital LCD clock so the current draw is minimal.
It is depending on the vehicle only possible to charge when the engine is running.
Great and interesting video Clive as usual....
Whew, 150$/month already. Just proves that you do quality videos for a great community.
Tried to become a patreon, but im a bit too young to verify my paypal account.
I DID - - I DID - - I Did go out and buy one of those sexy little LED Lights. It sits all by it's self on a shelf in the bedroom of our 36 foot Class A Motor Home which is (might I admit it) parked here in South Dakota in the midst of winter, when she is supposed to be parked down in Arizona! Damn I hate it when life gets in the way of FUN! At any rate, I had big plans for the little light but never got around to mounting her on my RV to assist in walking back from the club room late in the night after a few beers and lots of cheers from my fellow nomads!
The more you discharge a lipo, the safer it becomes. A fully charged lipo goes berserk. It was only a couple weeks ago a friend of mine breached a 6s 5ah 20C lipo. Thankfully only one of the pouches failed. But my word, dramatic noise and lots of very nasty smoke very very quickly. Finished off with a bit of a flame.
I think you weren't able to get the Lithium to react because Lithium-ion accumulators don't contain elemental Lithium. Only the non-rechargeable Lithium-batteries do, ifI remember right.
Great Video as usual! at 30:40 when you crank the little power supply up to 24V you can hear some high frequency tone sweeping up - is that some capacitor or the chip "working hard" - or maybe something else on your bench?
I used to do the reactions of sodium, lithium and potassium with water, the largest I ever used was about the size of a garden pea, more than enough toi be dramatic. More usually it was matchead size.
1:05 I am still hugely satisfied how my photocamera is still working after desperately wanting to learn how to swim (I got in an one-sided accident with my bike causing my camera to slip out of the bag in December 2015) in a typically Dutch "moddersloot" (muddy waterway).
Within 24 hours of the accident I have placed it in the oven (an electrical one, gas would be problematic) in a huge bowl of rice and let it sit for 3 hours at 40 degrees Celsius while carefully monitoring the temperature every 10 minutes.
The owner of the local photography shop is still absolutely baffled that the thing still works, because every camera with water damage he has seen stops working within 2 to 3 months of it coming into contact with water.
After it came out of the oven the haze that had gotten into the LCD screen had disappeared, and I was able to fire the shutter at command again, instead of it firing like crazy randomly.
A week ago I finally took the sand out of the lens that was on it during the accident and submerging, because at work has some pretty awesome tools for that and I managed to not only get the sand out (by removing every lens element), but I also got the lens back together, working AND as a bonus, got rid of a pretty awful color abberation at the bigger apertures! :)
Thumbs up for finger-probing the cap! :D
yay for rambles. Maybe you can get Ralph to interview you over suitable drinky-poos
What of screwdriver are you using in the video.. does your screwdriver set have a torx screw tri wing it has 3 Pronged and where did you buy them? Thanks😀
You get quite extensive kits of the precision drivers online. My usual one is from Poundland in the UK but you can also get 8 in 1 and 9 in 1 drivers online.
THose 12 volt car adapters seem to break quite often, usually because someone steps on them, I take the boards and use them to build an adapter to step a 12 volt 18650 pack down to 5 volts for a home built power brick.
my favorite channel by far thanks for the videos gives me something to do while drinking my 1/5 of jim
Brand new disposable Lithium batteries are the best source for Lithium. Open case, unwrap the contents and put the Lithium under oil immediately or it will oxidise in a few tens of seconds.
I always wondered how effective a finger is as a heatsink.
Lithium metal oxidises extremely rapidly in air, in particular if it is wet. The thin layer on the electrodes would be totally reacted in less than a second.
That's one of the better I've seen.
you can take apart an energizer ultimate lithium battery (AA is easiest) to get pure lithium.
But to get it to react you would have to put it into water as soon after you got it out as possible.
Thank you Clive, very nice video
Fun video as always Clive! I'm curious if you think those little10 W lamps would be any good for ceiling mounted shop lighting? I'll be heading over to Patreon soon. Be well.
+Pedunculopontine I'd say the little ten watt lights are good for either low level area lighting like outdoors at night, or for extra light down close to a work bench, but probably the cold white for the extra perceived intensity, and maybe a few for extra intensity.
Tsk Clive, the voltage of a nominal 12v car system will be 14.4v when the engine is running. If it's as low as 13.8v, either the alternator is failing, or it's a very old car with a dynamo, and you have all the electrics switched on with the engine only idling ;)
The charger looks to be the same as the ones you get with bike lights, they usually come with a 2s2p battery pack with inbuilt protection circuit.
wouldn't a boosting type of circuit help if you used a battery like alkalines because the voltage on them drops quite significantly which means you cant empty most of the cell when driving an led?
Good luck
Clive dropped his iPad in the toilet. Don't lie to us!! lol
HEAT MAN.. Next time heat the potted device up.. The Epoxy turns soft and crumbly, making it way easy to tear down! You can use a small heat gun or put it in a toaster oven!
+Travis Wizniuk Yeah, I was fairly convinced it was just going to be a resistor. If I'd thought it was more I'd have used the heat gun to remove layers. I've even baked resin encased things in my oven to soften them up in the past.
Just an FYI.. I love you videos, but I was cringing the whole time as pieces were flying off! Maybe just my ODC..
I also have a suggestion for a light teardown. I just bought a Stanley FatMax Spotlight. You would love looking at the inside of that (full of surprises).
+Travis Wizniuk Is that the tripod one with the batteries in the legs?
No its a handheld spotlight.. I know it looks pretty boring, but trust me its pretty neat inside. Here are a couple of links..

Where do we find the 10w Flood. Love the videos, Clive buddy,
+Mikey Peters
Best I can tell - eBay, search for item# 111762785517
It's the seller mentioned in the prior video (hidtop), and they look to be right, but/and also available in various power configs/price.
thank you
I should imagine your lithium had oxidised, when you buy it from a seller it's usually immersed in a mineral oil.
+Green Silver no, its not metallic lithium its a lithium salt to provide lithium ions
hooray the ipad lives
I like big videos more stuff to listen to Las having a flip around
Clive, your Flir camera can be patched to work exactly like higher resolution model.
Search for the model number of your camera and find instructions for unlocking the kernel.
Have you ever dealt with a ring modulator, deconstructing it that is? I've always been fascinated by those dalek voice changing devices.
+daikaiju20 MegaWayneD is probably the best channel to find out about that on. He makes a lot of Dalek stuff.

+bigclivedotcom Thank you Clive!
So many videos, thanks!
Congratulations Clive. You are the one who finally convinced me to sign up for Patreon. Patron #82!!!
Hey, I don't know if you read my previous comments on your last video, but there I also told I could not get a reaction from the Lithium combined with water... It's kind of silly, but I guess they are using some kind of Lithium that is more stable. Oh, and here in the Netherlands you can buy Sodium Carbide 15 euros for 5 kilograms. So if you want to play, get over here! :)
heating up the potting will make it soft for a while and then it chunks off
Before experimenting with pure Na, your friend should have watched the Periodic Table of Videos videos on Na and H2O :-). Being covered in burning Na bits would then not be a surprise :-)
Might be interesting to get a megger or similar to test PSUs at ~2KVAC or so.
Clive your oxidation theory is correct would you do me a favor and try cutting a battery while under water to prevent the oxidation?
I think oil might be a better immersion liquid.
+bigclivedotcom mineral oil is used to prevent reactions wiith m water in the air with acali metals like sodium so that prevents the reaction we want however if oyu could figure a way to get the skin of oil that is on your lithium when you put it into the water that would work perhaps you could use something like galium? it doesnt wet like mineral oil does
bigclivedotcom actually the lithium material in these batteries doesn't contain much free metallic lithium. It's in the form of lithium cobalt oxide or lithium manganese oxide. Those compounds form a sort of scaffolding with the lithium ions loosely bonded so they can move into and out of it as you discharge and charge the battery.
So cutting it under water or oil won't expose a significant amount of lithium atoms because theoretically all lithium in that battery should be in the form of ions. The bang you get from putting metallic lithium in water is due to it rapidly ionizing so if you start with lithium ions as in the case of these batteries there's no bang.
Jan Babiuch-Hall you are 1001% correct! It's named from the reaction not the "majority" component/contents.
Can you show us how you prop the ipad up?
some use the DC jack to disconnect the charge from the load
PS> What is the seller or search params for the little 10W light?
I'm already on Patreon for Daily Tech News Show and TekThing so there's no reason not to continue the pattern. ;)
Rambling is fun.
'Lithium ion batteries have zero metallic lithium in them. The flamability is mostly/all in the solvent based electrolyte..
Disposable lithium cells do have lithium (when they're fresh/not discharged), if you want to try to put some of it in water..
I liked that switchmode psu clive, simple but didnt have a nasty look, its a typical flyback supply (output on collapse of field), the chip sounds like one of those Top devices, although i dont like the power mosfet being inside the chip, i just dont lol :-D
.
I have one of those 830b meters by mastech, i applied a thick wire from the com terminal to the common pin of the i.c, the stray resistance dropped, and dump the nasty probe wires, resistance hell.
+zx8401ztv hehe, an 830b! asking for trouble! spend more than a quid next time, lol :P I let you off, a few years ago i bought one out of sheer curiosity about the amazing low price, of course the leads were trash right off, the sockets and then the casing let go, but it lasted a couple of years in my toolbox for light measuring, it actually remained perfectly accurate all along, build quality is the main issue, and anything with no fuse on 10a range im gonna kill anyway, lol
+jusb1066 ha ha :-D, now your not turning in to dave are you? lol.
Ive been using cheap meters for 30 years and im not dead (i dont think so), and ive never had one explode :-D.
Its how and what you use them for, ive had my old micronta digital reading 1000 volts when setting a psu on an old oscilliscope, it didnt go wrong or kill me, but im not daft... ok just a bit daft :), the meter was on a table and connected, then the power was switched on, i observed with eyes only he he :-D :-D
The mastech only 830b is fine, as long as you know its limitations :-D
But i do admit that the £2.00 non mastech ones just make me shudder lol.
zx8401ztv
no indeed i still have my first dmm, a 'testlab' made in taiwan i bought in 1988 at tech college, its used as the first grab and lives in the garage now, but still works just fine, i dont own any flukes! (i admit i used to), heck my 'best' meter is a £10 uni-t that i think electron-update tested last year!
+jusb1066 ha ha Welcome to cheap test meters anonimus :-D
Ok i have more than one 830b, the shame of admitting it :)
I like the icl7106 adc that all the cheap meters were based on.
My micronta 22-191 was bought from tandys in coventry a loooooong time ago for 80 quid, based on a seiko chip (didnt they make watches).
It still works and i upgraded the reference resistors and calibrated it last year, a good old digital (i can hear dave puking lol ).
the car charger that came with my 30w flood light has just a resistor on the positive terminal 12.6v pack inside the floodlight
6 cells 3 in series 2 in parallel
I have the same multimeter from eBay, paid about 5 euro's for it. The faceplate indicated that it was fused. It was not..
+Chris Slot They were meaning the leads
I don't really understand why they don't imbedded that circuit board into the light
How about you tell us your PayPal account so we can just pay what we like? Also I have purchased 4 of those 10w led floodlights. Love all the videos. Keep making them even upload the more rambling or boring ones. Maybe create a second Chanel for those of us that like that sort of thing?
great vid answered a lot of questions
Never heard Dremel used as a verb before.
Perhaps, one Idea for some support is that we send you things ? to look at
How about taking apart a dollar store fm radio a clipping the coil shorter to increase the received frequency of the radio to about 145 mhz.
+bigclivedotcom Is the "potting compound" some kind of epoxy/resin or a thermosetting plastic/resin, if it's the latter maybe heating the potting compound may allow you to expose innards in future deconstructions.
+James Lamb It was a resin type material. I've used a heat gun and my oven to soften similar substances in the past. I was a bit more violent with this one because I was confident it was just a resistor inside.
If your ipad gets damaged, you can always try out some chinese android tablets hehe just like your mobile.....(After the Motorola)....some decently good quality ones would be ones made by the bigger Chinese companies if you dont wanna gamble. A backup tablet is always a good idea though right.... Like your "on standby" mobile backup. Great vids :)
Another video idea.... Would be to review cheap, affordable, decent quality chinese tablets and mobiles....say up to £100.... Just a thought.(Try looking at Wish)
can you explain every electronic components how it function in different case in circuit.
Wouldn't that chip still have been hot from running at 24V ?
Also, if a cigarette lighter socket is fitted to a 24 volt vehicle, i think it would still be 12V as it's connected to just one of the batteries.
This means they could claim 'suitable for 12v or 24v vehicles', though as you proved, it will 'run' on 24v without going bang (for a short while anyway).
+Sparky Projects i think the more modern trucks do indeed supply 12v to the cab socket and people use normal car usb chargers for phones all the time, the older days of 20 years ago it was indeed 24v with the typical problem of trying to find anything that was 24v like a radio at the time, or fully insulating it from the ground/chassis was needed to do it with the 12v battery tap which was hard when you had an aerial to consider also
+jusb1066 When running a 12v item on a 24v vehicle system, you would connect to ground and the 12v point on the battery, did it a couple of times at work, no need for isolation, and this was probably 25+ years ago
+Sparky Projects Why would it? It's less need to drive the inductor current high to get same output at 24V.
+Sparky Projects A modest number of trucks do have 24V sockets. I made a truck driving friend a simple tester that indicated what voltage was present after he blew up several lighter socket power supplies.
+Sparky Projects the spec of the chip was up to 40v but i do agree ouch but in time for nov the 5th
Sodium can be bought from China. :-)
yeah sodium big secret lol . you can make it from table salt
I can see some one catching a plane with that little can. He or she will be occupied for a wee while. Lol
