    RGB laser driver ebay

    I thought it might be useful to upload a picture of the pinout of the green laser connection. Maybe it will help others with the same driver. I noticed one thing with the green laser fan. The used pwm signal is quite rough because it makes the fan quite noisy :mad:. I tried a few fans and there...

    RGB laser driver ebay

    I got all the channels working today. The green diode pins are the 2 with +G- next to it as I thought in the first place. The red and blue channels are simple to connect. It works perfectly as an analogue laser driver. There is a notable difference between TTL setting and the analogue setting...

    could you post a link to that thread because I don't know the search word to find it myself. Thanks in advance.

    I have the red channel working perfectly. The others will come soon. It's getting late here. just passed eleven o clock in the evening:) will continue tinkering with it tomorrow. I'll post the results when I get there.

    RGB laser driver ebay

    I just tried applying a signal to the modulation input of the green laser and i can switch on a white led connected to the right two pins (+g-) The middle two pins don't react to the modulation signal. It seems that Techhood was wrong about the pinout I guess. I discovered a possible second...

    the ''ts'' marked pins show 3,3V the left two pins 12V and the right two pins are 0V The pins on the red and blue are at 0V but that might be because there is no 5v on the modulation input.

    I didn't test the voltages yet. I'll do it right now. I'll get back to you in a minute.

    RGB laser driver ebay

    Thanks for your quick reply. I have seen that schematic but I meant the connection of the green laser diode itself, not the modulation input. There is a connector with 6 pins. Techhood told me that it's the two middle pins but the text next to those two pins is ''TS'' (temperature sense)...

    RGB laser driver ebay

    Hello Everyone, I recently bought this driver off ebay. I was wondering if someone knows this driver more ''in depth'' to tell me what the pinout is of the green laser connector. The driver I am talking about is sold by Techhood. Analogue RGB Laser Driver for 638nm 300mW 532nm 200mW 450nm...

    PT-30K scanner problem

    I have got it up to 30kpps and it shows the ilda pattern pretty good. Galvo amps were way off. I can play shows without the galvo's making a terrible noise as they were doing at the beginning. Thanks for your support. Edit: I've used a different soundcard driver and now it's projecting the ilda...

    PT-30K scanner problem

    Hello Cyperagon, Thanks for your quick reply. If I adjust the scan speed I'll end up with 14kpps (still at 8 degrees), that's way below some other results i've seen on other PT30K scanners. I have seen a post where he could get 25-27kpps at probably 20 degrees and still project the ilda...

    PT-30K scanner problem

    Hello everyone, my name is Jasper Vis, I'm from Holland. And I'm 21 years old. My number one hobby is tinkering with lasers (laserpointers and scanners) My laserprojector has the following parts: Cmedia CM106 soundcard DrLava's Correction amp PT30k galvos ~80mW green laser ~140mW blue 445nm...

    soundcard dac blanking problem. Need help.

    That's right. Lfi player has a ''blanking offset'' but it resets every time I start the software. It's very annoying. I have searched the settings files but I couldn't find the blanking offset value.

    soundcard dac blanking problem. Need help.

    Hello Everyone, I am using a C-media 5.1 soundcard dac in my RGB laserprojector but I am starting to think it's a bad card becouse there is a problem when I project a square, the left corner isn't closed. (see attachment) The lines are about 1cm apart from eachother. The problem shows also with...

    Blanking DDL

    Which ''base-resistor'' do you mean? I guess the one that goes to the 10k "abschaltstrom'' potentiometer?
