- This video was only made because for some reason I’m constantly getting messages and comments asking how to do this. (I’m not an expert)(definitely not an expert on small electronics) so I don’t understand everything about DP solid state lasers, so keep this in mind. I will say that most of my green lasers are counterclockwise for current up and clockwise for down, I don’t know why this is,
A potentiometer is a sensitive component so be careful, you shouldn’t mess with them because they’re usually set by the manufacturer in a precise way.
I suggest buying from Laserpointerstore.com
He talks so fast. I'm calling him lighting lips
Lightning lips!!! 😂😂😂 I hate you. Jk lol
PhotonsAcrossTheAir aww😢😢 I subbed lol. I don't like it when people talk slow af so I had to say that😆😆😆 ice video
PhotonsAcrossTheAir nice*. I'm your 980th subscriber
Woooohoooo lol thanks buddy. That’s okay. People always think I’m on crack 😂😂
Subjektive Gaming I just went back and watched it. Good god I need to slow down lol!
Nice video, picking up a handful of these 850/1s to play with soon. I also have a collection of high end and custom built lasers but I still enjoy the cheap ones! The reason for the direction of rotation is that the potentiometer is a variable resistor - so counter-clockwise is correct - lowering resistance > increases V = increased P. Cheers!
Ahhh. Makes total sense :D
I’m with you on that as well, the cheap ones are super fun to mess with. I actually ordered a 200mw 532 module to drop in my 850. 200mw of green equals about a watt or more of IR so I’m gonna have to modify a small heatsink in there somehow. I’ll probably just run it with a 15sec on 60sec off D cycle 🤔
@@04mach1speed Ive also been thinking about whats possible to mod with the cheapies and the 850/1 is probably easier because of how it comes apart vs the 301/3 series. Is the 532 from a lab module or something? Ive shopped a lot of directs but never looked into whats our there for dpss. And yeah, I personally run conservative duty cycles on all my lasers - especially my smaller ones with limited heatsinking. Deff need to post a video of that project post-completion!
Nick T yeah I’ve kind of done the same. I have actually been thinking of doing a 850/851 488-492nm but I would have to figure out how to add a spring to the driver
Nick T yes the 301 is definitely more of a bitch to get apart. But if you already have the presses and module/diode tooling.... that it’s no big deal. I have a lot of the cheaper lasers because I get nervous messing with some of nicer lasers that I spent a lot of time and effort building.
Such a shame that it costs almost the same to buy a high-quality 200mw green module/driver from China as it does to buy a 1000 mW green. I’ve left some comments about it on his videos… But I feel foolish having spent $90 building A 200mw pointer when I could’ve spent $30 more and built a 1000Mw green pointer five times the output! Such a shame 200 mW modules can’t be purchased cheaper!
@@04mach1speed I want to know, is there a way to turn the spring into wires instead?
Does The Green Laser 303 have a potentiometer? I wanna mod mine but im afraid of breaking so i wanna make sure that it has a potentiometer before opening it.
Laser diodes are current devices . If you exceed their limitations, they will AVALANCHE AND BURN OUT!! The potentiometer is there for one good reason... TO SET THE POWER LEVEL TO THE DIODES MAX LEVEL. IF YOU EXCEED THE LEVEL , EXPECT THE DIODE TO HAVE A VERY SHORT LIFE! NO EXCEPTIONS!
Or its there because your stupid country bans lasters above 1000mw
What is the reason for them having a built in power regulator. Also how do you know how much to overclock it so that it doesn't burn out.
I believe it’s because a lot of drivers are built for multiple kinds of diodes so when a manufacturer decides what wavelength they wanna put the driver in they can adjust the current accordingly. Just so happens that’s good for the consumer that wants a little extra power as well even though that’s not the intention of the manufacture haha! And it really depends on the wiper of the potentiometer or K rating I think? It’s really difficult to tell what the overdrive is on it. I mostly just guess. Luckily I have a LPM and that’s a good way to tell if you’re pushing it too hard. I know that generally most cheap 532s that come out of pointers can’t go much higher than 60-80mw without blowing it up so I just put them on my meter and adjust it till it’s 20-30mw over what they say it can go to. Example being that if the laser says it’s 40mw I’ll just bump it up to 60mw and it can usually take it.
@@04mach1speed Thanks for your time to reply!
Wish I had a milliwatt meter or some way to tell how much power is being outputted from lasers.
I was looking for this video. Thanks. This video will be güzide for my project thanks.
ill admit, when i made this video i didnt know that much about electronics but now i know a little more and some lasers nowadays dont actually have a pot. Just be super careful because just a little tiny bit more than it was designed to handle will certainly blow it up. lol
are you from turkish
thank you for this vid that helps understand some things, i had those cheap red 5mw lasers and i always thought the board still look complicated but is it really juts a switch and some resistors on them or is there a bit more to it than that? they seem more complex to me , also i wish i can find a cheap red with a pot on it ,always wished these things were brighter ,and if there is no pot is there a way to still somehow increase the current?
somehow their is, but i think you have to understand electronics very well, and i dont. im still learning as well. and thanks for the comment :)
@@04mach1speed yeah its all about understanding electronics to be able to modify the board to allow more current but then you cant go above the threshold of the diode, i wish i understood such things better
@@ARCSTREAMS im the same way, i know about 1-3% of electronics. that leaves about 97% i still still dont understand. I would absolutely love to understand it a lot more
@@04mach1speed electricity/electronics has always been a weird pain in the ass for me too lol
@@ARCSTREAMS I totally agree, resistors, Transistors, rectifiers, inductors, zenner leds, capacitors, and so much more! theyre slightly confusing to me, i would do anything to know how to build a driver board from scratch but understanding circuits and electronics is key and confusing to me lol. I almost want to go to school for electronics just for my hobby but that would be expensive haha
Destroyed my laser 303 trying to mod it. I ended up breaking the leads off the pump diode while removing the module. The laser 303 doesn't have a potentiometer anyways so it cant be modded easily. Most of the JD850/851 can be pot modded.
I just pulled apart one of Elay's 303 clones and I can report that there is no potentiometer to mess with in that unit. Its a fixed power. Nicely pressed together, it just took some tapping with thin screwdrivers to get the diode/driver out of the host. And it went back together very nicely and works perfect again. Good little laser for 12 bucks.
Ah that sucks. It’s fun to mod these things lol! But that’s good to know. Thanks for the input :)
Wait how did you upgrade the 303?
Nice Video To Mod Your Lazer As There So Good Mines Is Green I Got Off A Job Working On The Ship's,The Batterry Is The Massive One Not Little One's But It Has HAZARDS all Over It. Basicacally It's The Better Range Of Good Lazers & Cost Around Up To 20-30 Quid I Was Told Why Im Looking Into It's Spec's Now & This Just Look's Such A Better Idea ....10/10 Cheers
Charlie absolutely! Thanks so much for the input :)
I have seen 3 slightly different laser 303 designs
Come to think of it so have I
@@04mach1speed Two 303's I have are slightly different too. Both are pressed in. The older one had no support for the board for when pressing the switch causing the board to be pushed to the side wall like in this guy's video. I bent the board back straight and switch now is where it spota be. The second one they improved the design by inserting what appears to be a plastic shelf for the board to provide support when mashing on the switch. I'm going to try to press then both out to see if there is a pot on there or an smd resistor that might could be modded.
taterman320241 yeah that’s happened to me before, I know exactly what you’re talking about. I was always wondering why they didn’t do that to begin with. I bought one a couple years ago and when it came in the driver was actually completely broken off. I was thinking wtf! Good thing I know how to solder haha
Some may be counterfeit "copycats". That's a big problem in the internet marketplace...especially with rechargeable Li-ion cells.
0:46 most lasers on ebay is 40-50 mW? Eh no! Most lasers on ebay is 1-5 mW and if you can afford to spend 200 dollars than you could get a 1000 mW laser but i never spend those kind of money because i can't. 1-5 mW lasers cost like 1 to 4 dollars and for a 1000 mW it's 200 dollars if it's a 1000 mW i don't know
I have a blue laser with real 3w from sanwu lasers and it burns matches imediatly and i bought it with just 166 usd
It’s worth noting that these cheaper green lasers have a pump diode that is rated for a maximum output of 500mW of 808nm light, and that’s assuming it’s a QUALITY diode. The only way to significantly increase the output is to upgrade the pump diode and that’s not likely going to be easy for a novice.
Does doing this damage the lense as i want to do this but not to damage the lense either.
You need try this mod in the night!!
Chris Ro M I do! Lol
best thing you can do is get a higher rated wat laser board and diode. and if you really want to make it shine get better batteries that's the first step after upgrading the internals
Can you tell why he loses power, I bought a powerful blue laser with full batteries and dies?
watching from germany. Can you PLEASE ! speak a lil faster ?
Hi I took apart a simple laser pointer wanted to change the botton to a simple on/off that slides from ""on to off"" I faild...can you show me how to do that..thnks..may be on a video...
I never had a laser that came apart that easy
Hey,what is the model that you used in thi video?
801 I believe
OMG you used a magnet on the battery to the terminal! I've never seen that before! :P :D That is bloody brilliant! :P Well done! :) lol :)
Hah thanks, I have to give the credit to someone else but I can’t for the life of me remember who I heard it from, It was years ago. But yes it works great. :)
sure yeah ok
only works using neodymium magnets.. plus theres magnets in every electronic appliances so how come you didnt know
@@ItsJimdevera preferably nickel plated neodymium magnets. Note however, that some suppliers provide a REALLY thin nickel plating that can fail after a period of time or when mechanically stressed even a little bit.
I also use a nickel-plated neodymium magnet to adapt "flat" top cells to devices that normally require a "button" top cell. However, you do have to keep in mind that many flat-top cells do NOT PROVIDE THE SAFETY PROTECTIONS that are built-in to many button-top cells. So it can be up to you to ensure you don't overcharge, overdischarge, or short-circuit the cell(s).
Is there a correlation, equation, or chart that estimates output optical power as a function of input current from the battery? Measuring the current is very easy.
Or...there may a test point on the PCB at which one can measure a voltage that correlates to output optical power.
thats a good question, their might be something like that on Laserpointerforums. truth be told i got out of the hobby a couple years ago and im not in the loop about these thigs much. i didnt get out permanently, i have just had so much other stuff going on. ill eventually get back into it. are you a part of LPF.com? really good place.
@@04mach1speed I think I'm unfamiliar with LPF until now but there are a lot of things going on. I don't have any log of signing up for it.
Thanks for pointing it out.
😎
i have a laser lens that has been taken has spare parts or can it be repaired
it might be able to be repaired but these are so cheap these days it may not even be worth it
Hi, so I ordered 2 of these off of ebay, they both had potentiometers, and I was able to increase the power. I ordered 2 more from the same seller, they looked identical-but no pots. In fact, I think they're using an LED driver as theres no chips or capacitors, just 2 4 ohm resistors and a current regulator.. I ordered 3 more from different sellers and NONE OF THEM had pots. did they update/cheapify the design? do you know a source of the classic design with the pot? thanks
Yeah that seems to be a huge problem with 532s now. I noticed that some of the ones I bought also didn’t have Pots. Honestly I don’t thing their is a way to tell anymore if they’re gonna have them. So my best solution I found now is to just buy 532nm modules without a host or pen. Just the bare module and driver attached. They’re usually pretty good quality on Laserlands.net and Techhood EBay. You can see the pics before you buy them and can usually tell if they have pots. Hope this helps :)
Have you tried 303 and 301 yet?
Have you tried the laser 303 yet?
I haven’t, no. But I’m now looking it up
@@04mach1speed YES PLEASE
I have a chinese brand laser pointer 500 mile to 532nm green high power, but it doesn't burn anything because it doesn't have a focusing lens. If i put one on it, could it burn items by putting a focusing lens on it
Know anything about these lasers I saw your video I tried with one that I had and it's a little different than the one you have I couldn't unscrew that I out of there and I seen another video where a guy use a screwdriver to kind of tap around it so it'll come out well when I tapped around a little the 3 wires wires that are going to that copper colored metal thing with the eye came off now there's no way of pushing those back in right it's already messed up
Yea..my green laser pointer was similar but not the same..I ended up breaking mine trying to disassemble it to mod it. I was able to make it work again but its just not the same anymore. It no longer has a fine beam even when focused, it can no longer birn anything or scorch it. It's only good for the dog to chase now. Lucky for me I bought it used for $5.
Yeah that’s an occurrence on these cheap modules. I blew so many up by just slightly turning the Pot. I believe it’s mostly because manufacturers in China have a stockpile of drivers that are probably all around the same current (usually more than a 532 module can handle) and they solder the driver to the IR diode module and set it low and send it out. So 95% of the time the driver is a 500ma-1Amp so by turning it slightly it over drives the IR and can’t handle it. Good thing they’re cheap lol!!
@@04mach1speed Yea but mine just had a lens glued to it to make the green beam and focus it and I accidentally dropped it with the tip unscrewed off the end that had the adjustable focus and that lens popped off. I tried to glue it back but I never could get it in just the right spot.
Southern Catfishing I literally did the same thing years ago.
So if I have a similar driver/circuit board part but it DOES NOT have a potentiometer is it not moddable?
A Voltage Regulator will also work so that the lazer isn't constantly on all the time 💁♂️💭
I have this laser but I don't have a battery for it there I can find one??🤔
Batteryjunction is my favorite place for 16340s or LiFePo4 cr123s Amazon will also have them got cheap
Try a vape store they have them
Why do the red laserpointers have a fixed current driver? I have one from aliexpress. I guess i'll order a green one to, they where only 4 euro's or something.
My red jd 850 looks very different form the inside, is that weird?
Niek Benjamins I’ve noticed that as well, all my reds are the same way. Hmm I wish those had pots as well :(
Niek Benjamins no mine does also. I’ve noticed that us laser people love taking these apart haha
I want someone to answer the original question as to why red ones don't have a potentiometer
I just opened up my JD 850 and there is no potentiometer inside these different manufacturers really shit me up the wall . Everything that comes to Australia is always the left over inaccurate shit.
Bla b and the
Can you turn it up while the power supply is hooked up to it turn it up and turn it down that is
I have the 850.... how do you get the top part to screw off as mine doesnt seem to want to budge
Buy some clipleads and a cheapo multimeter. $20 should do it for you...
cool

Help! Yesterday my laser fell down on a hard surface when I was stargazing. After that it didn't turn on, only when I give it taps but now it doesn't turn on with anything. I have tried with full charged batteries but I don't have results

what if the driver board doesnt have a potentiometer?
Madcr0ws sometimes they don’t, if that’s the case than you can usually bridge the resistors but that’s too risky if you don’t know exactly what you’re doing. I have never done that but I know it can be done
Mine didn,t have that potentimeter screw thing, so i pushed that little round black button in that little raised square box just once and it does seem to be alot stronger and brighter. I could be just imaging this too, but im pretty sure its brighter. Mark.
M Henhawke I think that’s just a switch for by passing. Too bad you don’t have a meter to test it. Those meters are expensive and the only one I have I’m afraid to use for fear of breaking it :(
@@04mach1speed Yes. your probaly right. Mark.
@@04mach1speed I know this is an old post, but it's easy to test if the switch has been bypassed with a cheap ohmmeter. If you know the pinout of the switch, sometimes you can just look at the circuit board traces (connections) to whether or not the switch has been bypassed.
Do you have a link to this one I can’t seem to find any like it
joshua johnson laserpointerstore.com/laser-pointers/jd-850-laser-pointer
This is a good site where I get all my cheapies from and they’re reputable :)
OMG Thank You! I bought one from a garage sale for a dollar (missing switch button on case). Your mention of "case positive" prompted me to flip the battery around and find that it works! I'm so happy. TY TY.
thats great it worked for you, sometimes their isnt polarity protection so they usually get damaged so im glad it worked for you :)
@@04mach1speed no polarity protection means the batteries can go either way?
so you simply had the batteries installed the wrong direction?
@@ARCSTREAMS no polarity protection simply means if you end up putting the batteries in the wrong way then itll fry your laser. polarity protection just ensures that if you accidently insert the cells in wrong then the driver will cut any power instantly befor it ruins your Laser/Flashlight :)
@@ARCSTREAMS on 532nm lasers, theyre all DPSS so the IR laser is usually Case positive, meaning the batteries go in Neg first so that Positive is facing tailcap. I guess it sometimes depends on how the laser is wired but most all 532s are Case pos
Thnx for the tip
Uh
i have a 301 why doesn't it have a beam .-.
I have never seen a laser pointer with a fukin screw
With the first laser I had, you couldn't unscrew it, and I broke off the prism ^^

How do you disasemble the laser?
Is it possible to change the laser color? i have the green one but i dislike the color and i'd really like to change it to red
It is only possible by changing the laser crystal, which is practically the entire laser.
Mine doesn't have a potentiometer
My laser 100mw 303 model.can i upgrade 100mw to 200mw?
actually you can, yes. i have done this by just removing the 100mw module and putting a 200mw 532nm in there. but theyre kinda expensive if youre prepared to pay. I think I paid $58 for a 200mw module. but you have to be careful because it takes around 325mw or IR laser to generate 80mw of 532nm so @ 200mw of green its probably producing close to a Watt of IR so it generates a huge amount of heat
WHAT IS THE BATTERY
it is a 16340 lithium made by ultrafire
Hey, how can I increase power of my laser my laser don't have a screw to increase power
their is a way to do it without a Screw pot, but I have absolutely no idea how to do it. Im not that good with electronics lol
Can i replace this module to 200mw dx module?
OneCentDown _ you actually should be able to as long as it’s a 12mm module, most of them are so you should be good
thank
Mine is only turning red led can you please help
My spring was the same
Ok
How did you get this
Can it burn some stuffs?
Honestly, not really. Maybe some electrical tape but thats hard to do. You really need half a Watt to burn relatively good :/
It can burn some stuffs provided those stuffs are colored black and are not very thick. Mostly smoke and small pin holes you can achieve. Electrical tape suspended in the air is the best stuffs to experiment with.
When focused yes
my laser diode burned, Can i replace it?
I just bought one could you inbox me? I found something on mine that’s not very usual. Thanks

Hey Damien. I actually don’t really know any US sellers to be honest :( I can tell you that every time I buy a JD laser from Laserpointerstore it always ships from California, which is weird because the company is from China.

elqex ah that sucks. I have a feeling the U.S. is next. It pisses me off that lasers are banned in certain countries because of ass holes that ruin it for people by hitting planes.
yeah :(
@@notgabe4210 lol i got myne from bali and snuck it to aus with about 10 bb guns too
I have 303 and 851, both of their lens got scratches and now the 'dot' doesn't look like a 'dot'. Can you help us with an easy fix?
Thanks, btw love your videos
Yeah I’ve done that as well :( sometimes it’s better to just buy another 303 or 851 since they’re so cheap lol. I’m pretty sure you can pull the lens out and replace it but sometimes those lenses are half the price of the laser already so better to just get a new one. Have you gotten from Laserpointerstore.com ? They usually have really good prices
Thanks for the kind words by the way :)
I have installed a clear plastic piece in front of the lens (sometimes just cellophane tape as a *temporary* protection).
Hay photonsAccrossTheAir , how are you brother. I was just thinking it would be awesome for us that don't have the LPM if you could have yours present with you to do this mod to show us the factory output of the JD 850- 851 so we can physically see how much of a turn to apply up to 100mw on the LPM ..Just a physical visual template to the max output that you suggest .. Love ya work as always bro..
@Ambrose Killpack na man you are right on the nail no two modules get set the same they are not synchronized by a factory setting . I did think this as soon as I made the request it could lead to many of us burning our modules out .. This is a wise constructive correction of my theory and thanks for bringing this logical fact to my inquiries as my I don't want to mislead people I to thinking this is an option of accuracy.. I credit your input and the lesson reminded of this theory .. I guess no more than a 10 to 15 degree turn would be a safe limit . Without an LPM .. I stand corrected and thanks again .. there's always something to learn 😎👍much appreciated ..good man
@Ambrose Killpack mate you need your own channel on tube . This information I feel like writing down and putting it in my laser hard case. Thank you for the information. Smart man
@Ambrose Killpack no really man I actually feel like I've learned one of the most major aspects of laser physics much much appreciated 👍Damien Australia ... Thanks for spending the time to inform me and everyone else 😎👊🇦🇺
Damien Omen 6 good good man, how you doing? :) that’s a good idea for a future video. They’re all pretty much the same really, the 532s usually put out 40-50mw from factory so believe it or not, a very minuscule turn could bump it up another 30-40mw. Definitely wanna be careful because sometimes a half a turn could push it beyond what the IR can handle. A recent test I did indicated that apx 77mw of green light was using around 345mw of infrared laser light. Talk about inefficient lol!! But I’ll do a video soon to show this :) thanks again 😊
Ambrose Killpack this is 100 percent true indeed. Cheap laser pointers are like snowflakes, no two are exactly alike. Lol funny you mention this too because I bought 5 green 532s a while back and tested them, especially with the potentiometer tweeked and they of course were all different haha
What's the difference between the JD-851 and the JD-850? Which is better?
Ryan Idgaf truthfully I think they're almost the same aside from some cosmetic looks, they're actually about equal in quality and specs so it's mostly about personal preference :-)
PhotonsAcrossTheAir thanks man, much appreciated :D
Ambrose Killpack yes that’s correct, I actually had forgotten lol
@Ambrose Killpack well observed son 👍
Mine doesn’t have a screw
Yeah that’s a big problem sometimes. A lot of driver now don’t have them. Irritates me when I get one without one. Lucky they do still makes some with the screw but you have to get semi lucky
Can I do this with a 303
No dude the 303 doesn't have a potentiometer screw to turn it up ..only the JD 850 and the JD 851 laser have this function
Does the laser colour matter? Like, wouldnt red be best because red light is the warmest light?
Jul¡ hey J :) yeah color definitely matters, violet would actually be the best because it’s got the highest energy density, lowest wavelength. So purple burns the best, but purple doesn’t really go much higher than 900-1000mw. If you want raw power then Blue is your best bet. As weird as it sounds red is actually the worst. I found this out by doing an experiment with two of my lasers a 500mw red and a 500mw blue and the blue one will burn lots of stuff very well including your finger. Lol but my red one at that power just would not burn my finger, wood, and cardboard. It’s wired to think about but yeah Blue is the best for higher power
@@04mach1speed Thanks
@@04mach1speed Yeah, it's just so cool to combine physics with lasers, the lower the wavelength (λ) the higher energy density
SomeRandomDude YT I agree! It’s definitely cool. I would do anything to be able to understand everything about lasers. That would be awesome
