Hi all,
I'm trying to replicate the 'Laser Communicator' project that can be seen on youtube and other internet sites. I bought all the necessary parts and followed all the schematics, and I still cannot get it to work.:cryyy:
Here is what I am using:
The Transmitting Side
1. 405 nm 100mw laser powered by 9v (HighTechDealz)
2. Radio Shack audio transmitter
3. CD player (w/ U2 cd inside)
4. Audio cable w/jack
5. Alligator clip leads
The Receiving Side
1. .55V 500uA Photovoltaic solar cell ( 7/16 x 7/16 in.)
2. Mini-Amplifier Speaker w/ mono 1/4" plug to 1/8" jack adapter
3. Audio cable w/jack
4. Alligator clip leads
I couldn't find a video of someone using a blu ray for this project - only red & green lasers. Is the wavelength the problem?
If that isn't the problem, then lets get to the problem by process of elimination. I know the CD player, laser, and amplifier are working. I have 2 solar cells, and have tried both. The chances that both are faulty is slim, so I will eliminate them as the culprit. Audio cables & clip leads are new. Maybe the transmitter is faulty? Maybe the solar cell doesn't like U2? I'll put something else in if that's the case!
Does anyone have any suggestions? Any help is greatly appreciated.
Thanks,
Tim
