Did you solder directly onto the battery?! If you did, the batteries are screwed and now hazardous. Throw them away and don't solder directly onto batteries anymore. If you didn't, I'm glad. =D Test load the pot (potentiometer) and check the current reaching the diode. If you don't know how to...

Are you wanting to just char the wood and turn it black or actually cut the wood? Assuming you are just wanting to char the wood, I would recommend a 1w diode. They're not much more expensive, but will greatly improve burning speed and power. Also, ebay is a fine place to buy diodes. Just be...

PM Sent. Obviously I don't meet the requirements, but I might as well find out anyways. Although I'm positive I would meet the requirements in the future. Must lurk less... =D

So after seeing all the positive hype about these cheap things, I had to get one. $9 for incredibly overspecced 405nm? Heck yes. I ordered by emailing the seller and asking if I could purchase one without Ebay, since I'm technically too young to have one, and he said it wouldn't be a problem. I...

Well they sell them separately from the lasers, as you must also be aware, because the lasers turn a tidy profit for someone with the skills to properly extract them.

@kiyouken: Actually, there are a lot of optics in the projectors that are easily worth $50. Assuming they are included, this is a fair price for them. =)

Re: New Stock of Overspec 5mW Green Just got mine today. Shipping was much quicker than expected. Seems to peak at about 50mw!! However, maybe 1/10th of the time, it seems to dim down to about 10-20mw. Smokes leather, cuts tape, and all that fun stuff with the aid of a lense. Beam is visible...

Re: FS: 38mW green laser I'm (very) interested in purchasing it, but I'm curious about a couple things. 1. Where did you get it? 2. How long have you had it? 3. How much have you used it? 4. Did you measure the 38mw's with an LPM? Stupid question, but I gotta ask. Thanks!

I'm interested in getting one of these two lasers: 30mw 532nm Rayfoss Waterproof - $30 50mw 532nm Rayfoss Pointer - $26 But I figured I'd ask for you guys' opinions. Are these good lasers? I read the guide and Rayfoss was on the better list while still having pretty cheap lasers. 50mw for...
