I googled it a couldn't find anything intresting, I think that 2 transistor driver is just to make it blink at a given frequency but i would like to turn it on and off for depending of a signal.
I'm experimenting with a cheap galvo kit I bought on aliexpress, I also bought a cheap laser without a driver, I would like to make my laser blink. I have a few transistor with me, can i use them to make myself a ttl driver ?
thanks for your help.
So i guess for security reason it's better to buy 2 different laser. If I were to power one with a standard power supply, can I make the laser blink with a square wave to draw different point for example ? or do I need a special driver made for it ?
thanks a lot for your detailled answer,
this tutorial show how to correct the output of a sound card wich i plan to use to make the dac, i think i misread and the input of the said corrector should be +5/-5

it's hard to find the correct information, i found quite a few already that's why i'm asking here for more precise info. not a lot of peoples documented the process of diy galvo. also one of the link in the stickied thread is down.
I would like to build a laser scanner, but I have a few question before buying part,
I found a galvo kit online and after reading the sticked tutorial I found out i need : a digital to analog converter, a laser and it's driver.
for projecting indoor what laser power is enough ? what driver do...
