if your trying to add ma to anything, hook batteries in parallel. I'm assuming your not using this for a laser diode. get a bigger power supply to get more amp power. lets say have 12 volts(2 cells in series), if you want to get more current, hook there Positives and negatives together. I...

he meant mili amps I think. don't cap the m

I'm having a BIG problem with the battery pack right now. Its a Ni-MH battery, but its acting weird. when I run the laser now, it will shine bright, then drop in voltage quickly. Then when I stop it, the multimeter shows the battery rising from 0 to 9 volts again. what should I do? oh, I...

I finished my first red laser on tuesday and was so happy!  But it was kinda big and needed an adapter to function. I decided to move its guts into a new case.  I found a nice Ever Ready flashlight at a bargain outlet.  It was water resistant and it had enough space to work easily in. I bolted...

yeah, its a GB diode from senkat. not sure why, I have another one and it runs at 3 volts. the 4 volt one isn't any brighter or dimmer.

hey laserco. thats what I commented on. on youtube I said "this is fake, hes holding the hot part of the iron."

It works great and it burns too! thanks you guys for getting my started on the supplys and tips. But the weird thing is that the LD will only lase when at 4 volts. is that ok? I don't understand why. It works great though. Is it just "special"?, is it ok as long as it works?

http://youtube.com/watch?v=BRKmMmGdJI8 Don't worry, its not "another capacitor video" its actually different.

trust me, its accurate. I compared it with 2 other thermometers and its in range of them both. Accuracy to 0.5 degrees. I'll look for the maximum operating temp on the sheet. I just want to eliminate the need for a duty cycle.

I have a heat sink and everything for my LD when it arrives. But what is safe operating temperature? I have an IR thermometer so I can see when to shut off the laser. what temp is to hot?

Re: Daedal's Regulated PSU+solar cells+6 volt moto lol, I'll see what I can find. But how much would something like that cost? I found all these from broken solar lamps that people throw out. They think there "broken", but the batteries were just bad. ;D

if you want a nice beam, focus the lens back and fourth until it is teh smallest. If you hit the smallest point and it gets bigger, go back. for pointing at stars, focus it at the farthes object.

Re: Daedal's Regulated PSU+solar cells+6 volt moto I just need to find some more of these large cells and I'll be good. I only want about 1 amp so I can charge my phone and other small devices

Re: Daedal's Regulated PSU+solar cells+6 volt moto yeah, but this setup only gives me 350ma and I want more. So I need ones that are rated higher and use them instead.

yeah, focus it at something 10 feet or more away and try focusing then. Then you will have a nice beam

This is just a test to show what Daedals circuit can do for solar cells!

trust me! you need a driver. I though that would not need one at all, but I came here and everyone says that you need one. ask Daedal. He can sell you one. I bought one from him and I got it 2 days after I bought it.

Re: Starting tonight, 13 Sept - new GB for 16xdiod I bought 2 diodes a few days ago. can't wait!

Fantastic news for everyone! This guide will tell you how to get free internet by connecting your cell phone to your computer :D No wireless card needed! Requirements: 1. Windows 98/2000/XP 2. USB cable 3. RAZR cell phone!! you must have one! 4. USB port (duh) OK, to start off...

Hey Rhith. I could sell you the ones you saw in the video for $10 if you paid shipping. You can use a wall adapter that puts out 35 volts, or some other source to charge them. In that video, the capacitors were parallel. They DO NOT do good in series unless they are perfectly the same in...
