im a noob to the whole laser scene
i have minimal electronic experience and would be very grateful for some advice.

1st dose the driver i use depend on the diode im useing if so is there a refrnce to the drivers some where.

1) if you are going to build anything over 5mW, get certified laser goggles for that wavelength.

2) You need a driver who's voltage output meets or exceeds the forward voltage (Vf) of the diode you choose. Your driver has to supply Constant Current. Your driver has to be able to be set to less current than the amount of current it takes to kill your selected diode. For example; a 450nm M140 diode often dies around 1.8A of current, your driver must be able to be set to less than that amount.

3) Welcome to the forum and please familiarize yourself with the search function. The above information I have posted elsewhere about 20 billion times.

Search for Jayrobs builds, or if you want EASY then Survival lasers kits are great. But GET GOGGLES!

DMX is Greek to me, you might want to start a thread specifically about that...
