I'm not sure I unterstand the schematics, it only has one voltage source, where should I put the ttl signal ? Thanks for your help

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 laserpointerforumsXcom/threads/sound-card-dac-tutorialX40569/page-3#post-686384...

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...
