Uhm, I only paid 70€ for this whole laser system and it wouldn't make sence investing a lot in it.

I can control the TEC with the single driver board neither. Does it matter?

The driver has 0V output on the pins FN+/- and 0V output on LD+/-. But FN+ and 12V- connected are about 12V and LD+ and 12V- connected are about 3V. - So, yes :/ How did you find the laser diode? I think will order the RGB board I send earlier, not the whole laser.

I'm very thankful you helping me, thank you :) I don't really understand why I need a dummy with a constant power supply. Couldn't I just lower the current to a very low value and then connect the laser and turn it up to 500mA again? I will probably order this RGB Driver, so I can fix the...

The laser is glued and I don't want to risk destroying it. I also found a hidden sticker on the red laser: 650nm and "R500" (->500mw) So I only have to adjust the current, not the voltage? Simular laser diodes (635nm; 500mw) are sold with "operating current: 500 - 800mA" and "operating...

The 8 right pins are output. "+PM-" is input (left side) I don't know a lot about the laser: - It's probably from 2006 - written on it is "COLOR CANNON 300" - The system was already modified by someone before me (hard to tell which part is original and which not) - none of the PCBs has useful...

Hi, I'm from Germany, 17 years old and I'm glad to found this forum :) I have some experience with electronics and lasers and know the basics. However, I bought an RGB show laser from 2006. Unfortunately, the red laser driver does not work anymore and the green driver powers randomly when not...
