Gday folks
Recently I got one of DTR's great 520nm diodes with a X-Drive behind it (pushing 1.8A). If I power this thing its straight up full power. What I need to do is have a low power aiming beam, then be able to switch to full power after putting my goggles on.
My thoughts were (considering I have a spare flexmod) was to put the flexmod behind the X-Drive, set the idle current to just above the current required to get a low power aiming beam, and the max current to whatever gives the most power out of the module). I havent measured what full power draw is at 7.4 volts, as I dont have my saftey glasses yet (dont trust my wicked laser set, so have some ARG 33's coming from NOIR).
The whole purpose of this is so that I can use the module as a laser engraver with a foot pedal. The other option would be to simply build a two stage supply using LM317's to control the output current (or LM338's from memory for more amps).
I've fired the unit on my variable voltage current limited supply, and found it's threshold current. So would the flexmod have a fit if it was driving a driver instead of a diode?
Thanks for any input.
