The thing (lens?) covering the diode can off when I was pulling the driver and diode out. I can put it back on. But I didn't know if it mattered. BTW Module = Diode + thing (lens?) on top of it?

So far I have: Everything that comes with that laser LM317 (radio shack) 10Ohm resistors And the knowledge of new guy.

I only got the laser for a green diode. You are correct, it can with a driver. It was a laser pointer 'pen'. But getting a cheap laser, seemed easier for my first driver. PLUS if I messed something up it wouldn't be so costly. Here is the laser though: 5 in 1 100mW 532nm Mid-open Kaleidoscopic...

I'm building my first driver. I'm debating on using: 1 6v (lantern battery) 2 6v (lantern batteries) 12v adapter for an old land line phone. I would prefer the battery(s), but I don't know if that changes the Formula: 1.25 / .125mAh = 10ohm resistor Does the formula change if you use...

Yes Sir! EDIT: Or mam

Also, Any idea how many watts you need to have something catch fire?

Well any suggestions on where to buy parts? EDIT: My favorite video is this http://www.youtube.com/watch?v=NiKzrnKR3Ts&feature=related

I bought these googles for my green lasers: Green Blue Laser Eye Protection Safety Glasses Goggles - eBay (item 270719787819 end time Apr-12-11 18:21:08 PDT) Really cheap (compared to what LPF-members were trying to get me to buy), and from what I can tell work Really, really well. I can 'just'...

These are the highest wattage I could find. Perhaps you guys will know if they are worth it: 7.2V 600mA Replacement Lamp - RadioShack.com 5.2V 850mA Replacement Lamp - RadioShack.com

However, I know nothing about bulbs, the perfect batteries, etc. I would prefer to get everything from radio shack since it's down the street. Can Someone help. What I have, but don't necessarily have to use: 1 mag light (takes D batteries x3) 4 rechargeable 6v batteries 200mAh (I think) 2...

cool Thanks I just wanted to make sure I wasn't gonna destroy a diode while taking it easy. Any idea what that diode can handle though?

Is it possible to under-power a diode?

Cancel That! I found a good video. Most poeple were just showing off their driver when I was looking for "How to build a LM317. Now... Does anyone know how much current that diode can handle?

I found a few videos on Youtube, and This tutorial. But it doesn't make a lot of sense. Is there a 'Good informative video' to show how to build a LM317 from scratch?

I have the diode from this DVD burner: Asus DRW-24B1ST 24X Internal DVD Burner - DVD±R 24X, DVD+RW 8X, DVD-RW 6X, DVD±R (DL) 12X, DVD-RAM 12X, CD-R 48X, CD-RW 32X, SATA, 2MB, Black, OEM at TigerDirect.com I have a single diode. I heard there should be 2 in this thing, but I can't find it:can...

Facepalm on self.... :( + :crackup: I want to get Astronomy Certification. From what I read there is a test you take, but I'm unable to find it.

Or better yet. How do I know the limits for a diode I pull out of a blu-ray?

I got a few different selections. All in my signature.

Would it be possible to exact one of these diodes and replace a laserpointers Diode? If so how would I know max voltage, amps, etc?

I'm new... You mean the Diode form a 12x DVD burner right? or blu-ray?
