ttl to analog

[neutrino]

i found one of these kicking around in a box of bits. i'm guessing i can swap the driver out for two flexmods to make it analog. but the question is how do i know what settings to set the flexmods to?

thanks

Disconnect the + wire to each of the laser heads, and set your DMM on the 10A current mode. Then put 1 probe on the + output from the driver, and the other probe to the laser module + input wire you cut. Before you do this, short the output of the driver to make sure there is no power left in the capacitors. Then once you have the DMM connected, power the driver back up and you should get a current reading. Do the same for the other laser module, and you have your currents

And although the ebay page says they are TEC cooled, they clearly aren't so don't worry about that.

That makes complete sense. Should of thought of that myself.

Note to self: must get more sleep.

Rich,

I recently modified an AixiZ ttl laser to analogue using a flexmod. Here's my write up on it. Maybe it will help.
