I like this concept to recycle electronic components. One remark though, every time I was soldering, I had a terrible headache afterwards when I inhaled the fumes of the lead. It would be nice to combine this with a ventilation unit extracting these fumes.
Once again Robert I am amazed. To think of all the time I’ve wasted. After all these years, of salvaging components... mind blown!!!! Wow !!! We love you in Ohio. Stay safe Robert.
I remember the Wave Solder machines in the 1970s. The printed circuit boards with the components in place were carried over the solder bath on a track so that all of the component connections were made / soldered almost simultaneously. Your concept is very similar but works for desoldering the boards. At the time I was working for a company that was manufacturing switchgear for the United States Government's Intranet.
Great ideas. Love how you turned an otherwise random piece of scrap/waste aluminium into a neat metal enclosure, and built this whole device with recycled parts. I have an old sandwich toaster with a broken thermostat which should be perfect for replicating this project. Gone are the days of tedious desoldering of components with heat guns and and soldering irons. True wizard you are!!! Thanks
Solder pots are very useful. Almost essential when tinning Litz wire when making transformers and tinning the ends of thick cables or even tinning lots of cables quickly. Great channel as it's covers both electrical and mechanical aspects. 👍
Great job Rob - A word of caution to all who attempt building one of these - please ensure you properly earth your device - it may save your life.. Rob when you do apply your PID controller to this project consider keeping your bimetallic strip as a “ramp” control for the heating element . The issue being that in the initial heating phase of the PID will heat the element to glowing red hot and cause issues with your internal wiring etc... The bi metallic strip will eliminate this potential issue for you.
That's how I love it: Quick and 'dirty'. Very simple, but what a success! Mostly somebody looking for a small transformer, specified condensator or other item - might be cheap but difficult to get. And in this way you can arrange from stuff which goes normaly in the bin. I realy enjoyed this video; many thanks for uploading!
I have an older 3 burner Bunn coffee maker. I have been using it for years for hot water when I process scrap gold. Anyways there are two burners directly in front and on the side there is a burner elevated I now have a special purpose for that side burner Thank you so much. We love you in Ohio
Interesting video. I have the exact same electric cooker, scavenged from a junkyard for free many years ago. It ha been used extensively for boiling liquids, for rust blueing firearms parts and for melting lead for casting fishing sinkers and bullets AND I frequently use it for de-soldering boards by simply placing aluminium foil on the hot plate and placing the board on that and lifting off the components with tweezers. Simple !
I've seen this project done with the heating element from a slow cooker. Ideally a small bath would help as it would heat up quicker and retain more heat. Plus it's less solder to use, having it close to the rim helps too then because you're able to fit bigger components over just touching the surface
Totally awesome! I hate to think how long I have spent removing through hole components from boards. Especially ones with lead free solder! The joy of SMD and a hot air soldering station. I will be building one of these as soon as I can find the element. Thank you so much for your excellent ideas and instructions. You are an excellent teacher. Cool and kinda awesome! :o) xx
Cheered me up no end , I almost had a job on a tip, the stuff that people threw out unbelievable madness , caught on cameras making it bloody hard to pilfer rubbish, I Became a bin lorry driver, with the proviso I could use and stay on the dump at night , they welshed on the deal, I told them where to stick thier job ... I could have flown out of that place on/ in some kinda of hover hedge and stream hopping multi engined steam powered low hi tech hybrid , your program is absolutely fascinating , I’ve no where to build , watching and learning till I do .. Terrific fun
In the U.S., once people place the trash out for pick-up, it's fair game, unless prohibited by local regulation (rare and contestable) or they post "no trespassing" signs (it's not illegal to rifle through the trash, but IS illegal to trespass to do it.) It's surreal what people throw away... a friend of mine regularly drives through more upscale neighborhoods and has brought home easily repaired microwaves, TV's, etc.
Nice, I was not expecting you to do this. I always thought it should be more popular so all the good parts we throw away have a second chance to be used. Thank you, I appreciate that you made this video.
Interesting solution. I have used a Heatgun to desolder stuff from PCBs and it worked quite well, even for heat-sensitive parts. I turned the PCBs upside down, heated them up and pulled the components with pliers or a flathead screwdriver. Sometimes even shakeing is sufficient, depending on how long and how deformed the component's legs are.
Amazing mate I need to learn more about electronics pal wouldn't it be nice if we all lived in communities where there was all people's who had amazing skills and trades behind them and we all learned from them then these skills would end up being every day things you did sounds crazy and lar lar Landish but my friend it would be great for everyone as learning is a wonderful thing ! I love to learn
Rob you remind me of my with grade science teacher Some reason I always have liked my science teacher And one English teacher who taught The Lord of flies and 1999 big brother book Who would have thought that it would come to fruition Keep up the good work My teacher. Rob from Robert James. Maryland. East Coast Guard and the second half of the season ❄️
@@ThinkingandTinkering Thanks, I've got the same bits in a box waiting for a bit of spare time, I'm going to cut the top half off an old cordless kettle to make a heated container, and connect the base cord to the electronics
This device is called solder-pot and it can be used to solder circuits (if the pot is large enough), although this solder pot could be used in wire soldering or desoldering or soldering small circuits(including SMDs if design permits ). similar techniques are used in circuits manufacturing i.e. wave soldering, selective soldering.
If you heat Waxoyl to 60 C it runs like water. You can spray it with a £10 garden sprayer on your car chassis to stop rust. Better still you can spray it inside box sections and car doors. What I want is a way to keep it at 60 when it is in the garden sprayer and running up the small tube to the spray nozzle.
Found your videos yesterday and i watched and enjoyed them all. Love the fact that you are using a lot of old stuff than throw it away. You can put some more solder up to the edge of the tray, then you do not have to dip the PCB in, it can just rest on the edge. Burned PCB smells nasty. The aluminium box has to get a lot of heat because it is directly connected to the solder bath. You can drill a bigger hole and put some isolation like Kapton-type in between. Also for the heat element holders maybe you have some bits of ceramic or some fried electronic components for the isolation purpose? I would skip the bottom for some ventilation too. Made myself a small solder bath from an old soldering iron and a copper pipe. Nothing fancy but it does the job. Anyway good work & keep it coming!!
I just saw another of your videos and recognize the second circuit board you show in the beginning of this video, as the one taken from an old microwavevout of which you made an electromagnet plus a crank charger (with the induction motor) electromagnet from t
An old clothes dryer that still tumbles can be used. Remove the electric heating element and install a burner. Thow them in, fire it up and let it tumble. Noisy as all get, but very very fast and effective
I just use a cast iron pan on any given burner with a vent hood. Rather than using solder, I just use spent lead from my local range and give the resulting cleaned lead alloy to friends who do reloading.
Back in the 80s I remember hearing about some guys had figured out how to engineer carbon in such a way that it could be configured to extract any heavy metal so if you had a mix of toxins in a soup of dissolved ash’s from incinerating this sort of waste and passed it through the filters one could separate the different metals . I’ve no idea who it may have been and have often wondered if you might recall such a technology been invented. It would certainly be a tech worth developing , if I remember correctly I think I heard it on a science program on bbc 4, the technology’s that are left on the shelves that could make such a difference is criminal, and it’s not just greed but there is also deliberate destruction of this beautiful planet
Really nice job, Rob. I'm inspired to try a "room temp twist" with some galinstan I alloyed last year. I expect the trade off to be slower speed for safety and low complexity. Cost might not compare favorably unless you buy the metals and alloy them yourself, which is also really simple.
@@ThinkingandTinkering happy to.... I just recently got some cerium oxide to use as a minor alloy component (found paper suggesting high CO2 scavenging function of cerium-galinstan alloy) will try to make both videos at the same time.
quite hot is not enough said .The housing will heat to the temperature of the molten metal.Was there no thermal insulator in the original oven? As usual, a video with a great idea. I have to make that metal bath myrself, I will make a rectangular one, it will be more handy.
Really great looking project. Please be super careful of fumes if you do try this. Some real nasties are gonna be released that you definitely don't want to breath. Some sort of fume extraction is a must. With e-waste recycling in 3rd world countries people die early from doing this all day with no protection.
Very nice I like it. I have a hot plate like that and wanted to add a digital controller so I can use it as a heat source for making DIY surface mount PCB's. Temperature stability and accuracy is a big factor for that. But I guess I can simply add a bath on the top and turn up the temp to make one of these too! I think I'll check out plumbing solder for the bath as I suspect its a lot cheaper than RS or Farnells for the amount needed. I've also seen people use paint stripping heat guns for removing components for through hole stuff. The bath might also be good for SMD if you use a PID controller.
I've had good results with a 1500W hot air gun, usually sold for stripping paint. Solder gets a bit oxidized if you don't use flux but the parts are otherwise clean and functional. Long pliers or a screwdriver are really helpful to pull the part as soon as the solder melts, or they may just fall off if you shake the board a bit.
I do a lot of desoldering to get parts like transformers, relays and such. Have been looking at soldering pots designed for tinning wire ends but the pots in them are quite small and not good enough for soaking boards like this. Thanks for the video, this would tin wire and desolder. I have just bought a 3 in one rework station with an alternating power supply and ampmeter and was wondering if the heat gun will help taking boards apart, will have to wait for delivery I guess.
Another well presented video thanks. A very useful tool, when I think of the hours I take trying to remove components with an soldering iron. Just wondering if that thermostat is measuring the air temp inside the box not the tank temp. But it works and is close enough. Thanks again.
Its a good project but I do have a few concerns for your viewers and yourself. Earthing - make sure you have a good earth connection to all that metal, a few minutes putting a decent earth connection in could save your life if something goes wrong. Also if you can use a RCD plug it will be safer than waiting for the fuse to blow (I hope you checked the fuse is the right rating for the heater). The mains connection at the back that has been extended - enclose it in a piece of metal flex at least, the 'permanent' crimps are good but still should be enclosed for safety reasons. Goggles - wear them. if you over heat a cap - bang! there goes your eyesight. Gloves - even a cheap pair (of non flammable and non melty) gloves will save your hands from burns. And ventilation - as already mentioned - very important. If you don't have a proper fume extractor with activated filter at least use a small desk fan to draw the fumes away from you. Old solder contains a lot of nasty chemicals including lead and arsenic. Apart from that - its a great use of discarded items and your vids are inspiring.
Seems like it might damage an awfull lot of component's. Might it work better just using a copper plate? Can the pins conduct enough heat to loosen the solder just by Setting the boards on a plate? Also, I would consider a vent hood, beryllium oxide ain't no joke.
Great piece of kit. I don't want sound like I am having a whinge but could have your music at the same volume as your voice as I have my volume turned up to 11 to hear you when the music plays I get in the S )-( i t. Thanks again great content.
You briefly mentioned that some components would be damaged. Plastic connectors, certainly, but what of the other types of component - capacitors, relays, resistors etc? Maybe it is an art, getting the timing just right and having the extractor tool (pliers) immediately ready?
Why didnt you put the heating element inside the little pan so you could use much less solder to fill it up? Seems like it would get more heat transfer that way too...
Robert, your work inspired me to start work on my own home-lab where I plan to essentially mess around and have fun building, breaking apart and re-purposing machinery to suit other needs. However, I am a bit of a novice in equipment I might need, so do you have any recommendations for some basic lab equipment or machinery I might want to purchase to start out? Alternatively, if there's anything that would be useful to have but I could make myself for a cheaper price, I would greatly appreciate you letting me know. Thanks so much for these videos.
hiya mate - the main things you need are space and time - after that it depends on what you want to do. there are loads of videos on my homemade lab equipment playlist - and many other people's as well of course. best of luck.
some components may benefit from getting cooled somewhat fast, I'd suggest making a metal box with a good fan blowing on the parts for that purpose. basically almost the same box, but the hole is on one side at an angle with a fan, and it is upside -down if you have one laying around, microwave fans are pretty good for that purpose.
Couldn't you just have a bowl of water nearby and dunk the bits as you get them off? Not many components will be damaged by getting wet provided they are dried off before being used again or corrosion starts to take effect.
I never tried it but I think a hot SAND bath would work instead of the liquid solder if you can get it heated hot enough to melt the solder connections. That MIGHT also work as a hot plate to use jars instead of special Pyrex beakers for heating liquids since the sand would heat the jar more evenly than a normal hot plate.
I thought I might suggest making some kind of tray that you could set on top of the bath, that way your only dipping the solder joints and you have an extra hand. Also I am not sure what kind of gauge wire you use but you can get smaller spools of kanthal at vape shops (at least here in the states you can) if you were looking for custom dimensions on your heating element.
I think you are supposed to fill the bath to the top mate and just dip the joints - I used the heating element from a hob - I was suggesting kanthal - you would need to match gauge to ensure amp draw at voltage you needed as I used an old appliance where that had been calculated for me I didn't need to do it - but you can if you want mate
@@ThinkingandTinkering sorry for the confusion, I forgot to type entire parts of that comment. I realize you used a premade element. What I meant was that if someone was going to make their own heating element I dont know what size wire they would need. It would be easier and safer to do it your way considering someone already did the engineering on it for you. As far as my suggestion of a tray, that was suggested with the assumption that the pot should be much fuller. I can see myself dropping a smaller board in and splashing hot metal on myself.
Cats pyjamas, be worth getting a cheery picker , dangle off that mid air and rummage away !! An old man throwing away a 10 speed push bike at local tip, I did see, and I’m avin that, pulled it out the scrap, when a gorilla shows up telling me to put it back , when this sharp old man intervenes saying he’d changed his mind , gorilla confused gave a grunt, the old man then awards me his old bike !! Two out of three ain’t bad 😆
That's really cool Robert, I might have to build one of those. I bet it will fry transistors and IC's. Did you use solder or lead in the melt pan/pot? The melting point of lead is quite a bit hotter than the solder. Thanks
You might consider using a bit of resin flux in the pot. It should improve thermal conductivity thereby causing the solder to melt faster so that you can get temp sensitive items out of the pot faster. Then again, I might be talking a load of rubbish.
Yes excessive temperature can damage some components like IC's, semiconductors [transistors, Mosfet's, various types of diodes] and electrolytic capacitors. I thought about just using a $15 Dollar General/99¢ Store hot plate [Glowing red coil type] that has a temperature control using a cast iron skillet. You could use another type but I believe cast iron would maintain temperature better. Typical solder 60/40 melts at 370°F so you would have to use a temperature probe and I also thought of trying vegetable oil???
I think vegitable oil would be a sort of mess to clean the parts. Sounds like youd need alcohol or acetone bath. And the oil and may oxidize and go rancid.
.......silicon and gallium arsenide components aren't so easily damaged by heat these days plus components are built more and more to withstand higher temperatures. .I just have too strong a memory of all the costly germanium semiconductors I heat damaged long ago .. When soldering or unsoldering I'll dob a dab of cold wet ceramicist clay onto case of expensive looking semiconductors as heat sink to keep em cool . Where do we get the clay? ...from pottery ceramic supply shop which is same place to purchase copper, zinc ,nickel etc oxides and potassium carbonate....... that have all been required at some point in the videos ..These days here in Australia we can no longer obtain antinomy, flourspar ,vanadium, graphite powder componds and other stuff from them.
Second board is a power filter, probably from your now ex-microwave oven. Also, it's been 2 years I've been wishing to have a desoldering bath.. you're reading my mind.
I like this concept to recycle electronic components. One remark though, every time I was soldering, I had a terrible headache afterwards when I inhaled the fumes of the lead. It would be nice to combine this with a ventilation unit extracting these fumes.
extremely important

I have just bought a 3 in one rework station with an alternating power supply and ampmeter and was wondering if the heat gun will help taking boards apart, will have to wait for delivery I guess.
Awesome ive wanted to make one of these
go for it
I'm curious to know if you have any patients or inventions ? If so please do a video about it
Another well presented video thanks. A very useful tool, when I think of the hours I take trying to remove components with an soldering iron. Just wondering if that thermostat is measuring the air temp inside the box not the tank temp. But it works and is close enough. Thanks again.
brilliant mate!
cheers mate
That's a great idea 👍
cheers mate
Its a good project but I do have a few concerns for your viewers and yourself. Earthing - make sure you have a good earth connection to all that metal, a few minutes putting a decent earth connection in could save your life if something goes wrong. Also if you can use a RCD plug it will be safer than waiting for the fuse to blow (I hope you checked the fuse is the right rating for the heater). The mains connection at the back that has been extended - enclose it in a piece of metal flex at least, the 'permanent' crimps are good but still should be enclosed for safety reasons. Goggles - wear them. if you over heat a cap - bang! there goes your eyesight. Gloves - even a cheap pair (of non flammable and non melty) gloves will save your hands from burns. And ventilation - as already mentioned - very important. If you don't have a proper fume extractor with activated filter at least use a small desk fan to draw the fumes away from you. Old solder contains a lot of nasty chemicals including lead and arsenic. Apart from that - its a great use of discarded items and your vids are inspiring.
thanks for your concern mate
17:51 watch out for heat on the Capacitors
electrolyte vaping is the future
@@johanponin1360 Going BANG is a danger
@@3D_Printing Tantalum caps, from what I've heard, will burn. I use them I just make sure I don't install them backwards.
Seems like it might damage an awfull lot of component's.
Might it work better just using a copper plate?
Can the pins conduct enough heat to loosen the solder just by
Setting the boards on a plate?
Also, I would consider a vent hood, beryllium oxide ain't no joke.
Great piece of kit. I don't want sound like I am having a whinge but could have your music at the same volume as your voice as I have my volume turned up to 11 to hear you when the music plays I get in the S )-( i t. Thanks again great content.
Sorry about that - I meant to but I did the render around 10 last night and I was tired and forgot
You briefly mentioned that some components would be damaged. Plastic connectors, certainly, but what of the other types of component - capacitors, relays, resistors etc? Maybe it is an art, getting the timing just right and having the extractor tool (pliers) immediately ready?
Why didnt you put the heating element inside the little pan so you could use much less solder to fill it up? Seems like it would get more heat transfer that way too...
Also good for wire Tinning
for sure mate - and tinning lugs mate?
Robert, your work inspired me to start work on my own home-lab where I plan to essentially mess around and have fun building, breaking apart and re-purposing machinery to suit other needs. However, I am a bit of a novice in equipment I might need, so do you have any recommendations for some basic lab equipment or machinery I might want to purchase to start out? Alternatively, if there's anything that would be useful to have but I could make myself for a cheaper price, I would greatly appreciate you letting me know. Thanks so much for these videos.
hiya mate - the main things you need are space and time - after that it depends on what you want to do. there are loads of videos on my homemade lab equipment playlist - and many other people's as well of course. best of luck.
some components may benefit from getting cooled somewhat fast, I'd suggest making a metal box with a good fan blowing on the parts for that purpose. basically almost the same box, but the hole is on one side at an angle with a fan, and it is upside -down
if you have one laying around, microwave fans are pretty good for that purpose.
Couldn't you just have a bowl of water nearby and dunk the bits as you get them off? Not many components will be damaged by getting wet provided they are dried off before being used again or corrosion starts to take effect.
I think that surrounding the part with Blue gum, like the one we use to hold posters on a wall will protect it from overheating.
cheers mate
Super Idee!
cheers mate
How about and induction cooking burner with temperature control
I never tried it but I think a hot SAND bath would work instead of the liquid solder if you can get it heated hot enough to melt the solder connections. That MIGHT also work as a hot plate to use jars instead of special Pyrex beakers for heating liquids since the sand would heat the jar more evenly than a normal hot plate.
you should try it mate - that's a nice idea and worth a try just to see
U R Amazing ... Palestine
I thought I might suggest making some kind of tray that you could set on top of the bath, that way your only dipping the solder joints and you have an extra hand. Also I am not sure what kind of gauge wire you use but you can get smaller spools of kanthal at vape shops (at least here in the states you can) if you were looking for custom dimensions on your heating element.
I think you are supposed to fill the bath to the top mate and just dip the joints - I used the heating element from a hob - I was suggesting kanthal - you would need to match gauge to ensure amp draw at voltage you needed as I used an old appliance where that had been calculated for me I didn't need to do it - but you can if you want mate
@@ThinkingandTinkering sorry for the confusion, I forgot to type entire parts of that comment. I realize you used a premade element. What I meant was that if someone was going to make their own heating element I dont know what size wire they would need. It would be easier and safer to do it your way considering someone already did the engineering on it for you. As far as my suggestion of a tray, that was suggested with the assumption that the pot should be much fuller. I can see myself dropping a smaller board in and splashing hot metal on myself.
what is the best material for the tray?
j'ai appris quelque chose aujourd'hui .
so easy!
for sure mate
Recycling,,,👍
absolutely mate
Put a rectangular (more practical than roujd) plate over your kitchen electric plaques , control the temperature, and there you go?
Am I wrong?
thanks Robert, I have never heard of one before, I will keep it in mind. Thanks for showing. Any updates on the earth batteries project?
cheers mate and not yet I am afraid
0:42 That board came fron a microwave oven. How I know ? I watched you dismantling it 😁 Cheers 🤝👍
Cats pyjamas, be worth getting a cheery picker , dangle off that mid air and rummage away !! An old man throwing away a 10 speed push bike at local tip, I did see, and I’m avin that, pulled it out the scrap, when a gorilla shows up telling me to put it back , when this sharp old man intervenes saying he’d changed his mind , gorilla confused gave a grunt, the old man then awards me his old bike !! Two out of three ain’t bad 😆
That's really cool Robert, I might have to build one of those. I bet it will fry transistors and IC's. Did you use solder or lead in the melt pan/pot? The melting point of lead is quite a bit hotter than the solder. Thanks
solder mate
what did you cut your steel with mate please?
What ya doin too your hair Rob, You going for the Vanilla Ice look ?
You might consider using a bit of resin flux in the pot. It should improve thermal conductivity thereby causing the solder to melt faster so that you can get temp sensitive items out of the pot faster. Then again, I might be talking a load of rubbish.
lol - what I read said better no flux - but I always find if someone has one idea some else has exactly the opposite lol
There you go. It was a load of rubbish. There's probably flux left on the solder joints anyway.
Yes excessive temperature can damage some components like IC's, semiconductors [transistors, Mosfet's, various types of diodes] and electrolytic capacitors. I thought about just using a $15 Dollar General/99¢ Store hot plate [Glowing red coil type] that has a temperature control using a cast iron skillet. You could use another type but I believe cast iron would maintain temperature better. Typical solder 60/40 melts at 370°F so you would have to use a temperature probe and I also thought of trying vegetable oil???
all worth a go mate
I think vegitable oil would be a sort of mess to clean the parts. Sounds like youd need alcohol or acetone bath. And the oil and may oxidize and go rancid.
.......silicon and gallium arsenide components aren't so easily damaged by heat these days plus components are built more and more to withstand higher temperatures. .I just have too strong a memory of all the costly germanium semiconductors I heat damaged long ago .. When soldering or unsoldering I'll dob a dab of cold wet ceramicist clay onto case of expensive looking semiconductors as heat sink to keep em cool . Where do we get the clay? ...from pottery ceramic supply shop which is same place to purchase copper, zinc ,nickel etc oxides and potassium carbonate....... that have all been required at some point in the videos
..These days here in Australia we can no longer obtain antinomy, flourspar ,vanadium, graphite powder componds and other stuff from them.
indeed mate poetry suppliers are a cool source of lots of 'stuff'
Second board is a power filter, probably from your now ex-microwave oven. Also, it's been 2 years I've been wishing to have a desoldering bath.. you're reading my mind.
how about sand heated
Sorry Robert I’ve forgotten how to get your “0ther” shop please advise, thanks mate
