FlexMod P3 Analog/TTL Laser Diode Driver

[j4cbo]

It might be worth bolting a TEC and a Flexmod to this baby.

I don't recall any DPSS pointer cores making 800mW CW for short periods. Anyone already got their hands on one of these? It would need some rather beefy heatsinking and modulate like a pile of horse-manure, but it could be a good 800mw labbie on the cheap.

By "800mW", they probably mean that the pump diode produces 800mW - that was the case with a "500mW" dinky 532nm pointer that appeared a while ago. Or maybe the pump diode *consumes* 800mW. They aren't above flat-out lying.

Yeah, if they aren't trustworthy to list the output power, why would you trust them to list the pump power? Why would you trust them to send anything? I actually feel safer buying Chinese crap on ebay, because at least then you can leave bad feedback when it doesn't live up to the specs. With websites like the one listed, there is no recourse.

In trying to pick the right Lasorb to use with the Flexmod P3 when driving two diodes in series the voltage requirement leads me to the 833 series. But, when modulating the diodes, acording to the Pangolin data sheets, when a significant voltage drop is associated with a current modulation the Lasorb might detect this as an event and interrupt the modulation. There are two sub-series the 833-121 and the 833-122. Does it matter? Which would provide the best protection and still allow reliable modulation? I should have 4 Flexmod P3s on the way without any Lasorbs ordered yet.
Thanks

Its been about three weeks since I ordered 4 Flexmod P3 Drivers. What is the usual turn around time? My project is on hold and I sure could use them.

I am in the same boat...ordered 3 weeks ago and no dice. No money has pulled from my account, but I am waiting on this one part to make my projector go. I emailed Dr. Lava via the email provided by google checkout, no response as of yet.

Quick "service" question... The driver I have has the red LED illuminated (it is the prototype from DZ). How do I reset the interlock?

"

If the interlock circuit is open initially, or if the output is open
circuit, a red LED will illuminate and no current will be passed to the laser diode until the diode circuit is complete and the
interlock reset.
If, at any time during operation the output circuit goes open, the driver will shut off output and illuminate the red LED until

the output circuit is closed and the interlock is reset.

To reset the interlock , you need to solder the "interlock" wire ... I did so !

And if your still having trouble to get the RED LED go away (like I had) !
I had to adjust the 2 POT to ZERO !!

Then the RED led goes away and it all works fine

A tip can be to have a 5mm LED on the output (and not the laser diode) !
I learned the hard way my 445 diode BLOW on first test, because the pot was adjusted wrongly when it was off.

If you'd followed the setup instructions, you couldn't have blown the diode up, as you'd have set the current first with a meter.

[allthatwhichis]

I think the interlock wire has been soldered on this already as it was the one from DZ's review and was powering a 445 already. One day the red LED lit up and hasn't ran the diode since. I want to try it on a lil greeny I got and need to find out why the LED is on.

[kecked]

try an led. it works the same and will show you current.
