Hi, have searched a couple of days and tried to find out how to build laser. I have also read your posts from building first laser, but everywhere is so general everything. I know what i need, but im in stuck with my driver. It may seem to you pretty stupid question, but im new and i dont know much. Can you try to explain me with simple words whats TTL driverboard. If im gonna buy one what i have to do connect with TTL modulation? How to use it? I have read some explanations, but everywhere i found something similar, the answer is so complicate. If im gonna build mu first laser, which driver board do you recommend to me? Thanks a lot for answering and please no hate because someone maybe is already asked this question.
