Hey guys,
New here posting though I've been a lurker for a while. I recently purchased a 445 diode from a Casio projector online. I also bought a Flexdrive driver as well, but I really don't want to have to deal with the preset Mw setting of the flexdrive all the time. What I'd like to do is have some way of dropping the voltage to the diode from flexdrive. I thought I could just wire in a pot between the the two but after doing a lot of reading here on the forum it seems that that would be a bad idea due to possible voltage spikes to the diode as the pot "rolls over" it's internal coil. That got me thinking that what I needed was a pot that was controlled electronically rather than mechanically, so I found this online: Digital Volume Control
It's a circuit that with some additional switches and a capacitor can control the volume of an audio device, I'm assuming a pair of headsets, similar to how one might up the volume by pushing the up button on the side of an mp3 player. In theory, I'm assuming one could "step up" or down the voltage coming from a flexdrive to a diode by injecting this circuit between the two and thus lower or raise the output of the diode up to the maximum of what the felxdrive is set to. Ideally I'd like to turn down the power going from the flexdrive to diode to zero and then to max by just tapping the up and down buttons.
Since the company that makes this circuit gives away free samples, I went ahead and ordered one this past week, but I thought I might just post this here on the forum to see what anyone might think.
Thanks!
