I built one some years ago, still working fine ! Mine uses batts from a scrapped Laptop batt pack. I put in a circuit to charge them via USB. Nice video, thanks !!
Very useful tutorial! Recently I detached a laser diode from an old DVD Writer SH-S223. It's an open type diode with no glass protection. I'm using this schematic with LM317, the resistor is around 14 ohms, but the diode (in its original, though small, heatsink) gets hot after 2-3 minutes of work. Is this normal or I have to add more resistance? I'm using two 3,7V Li-ion batteries in series for power supply. Unfortunately I couldn't find diode specs anywhere to see its operating current.
What wattage should the 3.3 ohm resistors be? I also have an old 500mw laser diode. Can I still use the same schematics, using the lm317 and 3.3 ohm resistors?
you can use the exact same schematic yes. But you will need to use a different resistor to power this. In the video the guy posted the formula to find the output amperage of the driver. the current output is 1.25v divided by the resistor value. Experiment with the resistor value on paper to find the correct current value that will run your laser diode.
Hi! In your video there is a list of dvds and their diodes. Can you please give us a link to that resource? I'd really want to know what is the maximum current for my dvd laser diode
I would make a mold of a tiny cylinder diner, not too large yet not too small. Fit inside the fully soldered and connected LM317 ballast. Use rubber insulated wire for the inputs and outputs. Fill the mold with resin, and wait for it to harden. To make sure the wires don’t screw up, use a thick set ceramic glue to cap off the wires going in and out, almost like that on flyback transformer pins. Then make a thin 3D printed case, fill it with a tiny amount of the same ceramic glue, and press fit it on. Put a nice sticker on it, and try to color code the wires.
Hello, i just built the one u focused on your video (the simpler model), but i wasnt able to burn down a thing.. is this model suppose to do this? or is it more similar to a normal 'shop bought' laser.. Tnx! P.s - i even attend the lens to change the focus, but it didnt work
I made a circuit with a lm317 voltage stabilizer as in a film and when it gives a voltage of 4.22V per diode it gets 3.58V and when it gives 9.96V voltage per diode it gets 9.28V . My resistor has exactly 4 ohms. Should it work that way? The electrician in the store told me that this arrangement does not make sense. What should I have voltage on the diode? Please reply .

Do you happen to have any info about what kind of temperature you can achieve using a battery powered setup like this? Have you ever done any thermal measurements of a surface that's directly hit by the beam? I understand that the actual temperature reached is mostly related to the physical material properties of the object and for how long it's been absorbing the light's energy, but I'm just interested what a simple diode on a lithium cell could be capable of in terms of cutting through/into certain materials. (more specifically: can a setup like this ignite a small spot on a piece of charcoal before the battery is drained you think?)
Зачем ограничивать напряжение для NCP1529? Cycle-by-cycle Current Limitation From the block diagram, an ILIM comparator is used to realize cycle-by-cycle current limit protection. The comparator compares the SW pin voltage with the reference voltage, which is biased by a constant current. If the inductor current reaches the limit, the ILIM comparator detects the SW voltage falling below the reference voltage and releases the signal to turn off the switch Q1. The cycle-by-cycle current limit is set at 1200 mA (nom)
@@joeycorbett2263 If this confuses you so much you should just give up this project. Your question is like asking 'how do I know if this light bulb in my ceiling is burned out or not?'
Yes lasers diodes are quite easy to make in your kitchen with a very hot oven. You will need some Gallium, some Arsenic, a bit of aluminium might be useful, two tblspns lemon, and a pound of Sugar.
Hey I was wondering if the heat gets unbearable for the later? I am about to assemble one and the thought went through my head- won't the diode just pop when you turn it on? You are effectively making a generator to reach enough power for the diode but... Isn't it too much? Or even if the diode survives isn't it getting too hot?
Nice, I tried it but with different setup, my laser comes on but can't burn, i measured the amperage i get 0.39mA at 3.3volts, am using a netgear modem router as power supply, there is a transistor inside that supplies 3.3v not sure the amps but it can light up white LEDs at 3.3v 0.35mA too, i tried to see how many it can power and the more LEDs i put the more amps it ads like for 3 LEDs mA goes to 0.56 and they stay at full bright.
Hi Man, Thanks for share, maybe do You know Why my Laser diode does not have enough power?? I made the exact same conections that You do, the fist time I connected the circuit it powers on like yours but not enough to burn, so I decide reduce the resistor to increase the current but now it it almost not light is produced.
Problem: I set everything up with aligator clips (not soldering until I test the circuit wors. and it worked fine), then i shifted the circuit slightly and the diode stopped emitting light. I found it was quite hot to the touch. I reconnected everything and nothing, then I began to smell something, the LM317 was burning hot, literally, I burned myself touching it. What happened? any idea?
