Dual driver now in stock at Lasershowparts

I believe you already sent me the manual. I have it in my inbox. Thank you, sir!

Connectors? I prob tossed them in my hurry to set it up. Lol anyhow I would think you would want to solder everything anyhow. These pads solder very easy, board layout is great. Working perfect for me. Will be ordering more.

The things I'd like different would be finer tuning on the pots. Meaning the total physical range is short not even a turn end to end that when removing an adjust tool it slightly moves it from set point. Atleast with my shakey hands. Also for driving a 9mm little more Current would be nice.

Thanks!

noted for the next assembly run perhaps

Dave, any idea about when you should release the bigger driver?
Also, are we talking about a heat/cool dual TEC feature?

Hey Seb, when i have some spare time, Ill do a bit more work on it.

At this stage its going to be single diode driver, single tec driver bidirectional PID control

Seconding what polishedball said.... single turn pots are temperamental. I have steady hands and even then, the slightest tweak sends the current up or down by about 50ma. Still workable and I am really liking these drivers but the 1 turn pots have got to go!

This is a 12 turn pot that should fit the same as the single turn. I don't know the resistance this is 10k.

I do have some 10 turn pots on the shelf.. To replace the existing pots with the 10 turn, not too much of a problem, Ill make sure what i have fit, than go from there

I have never had a issue with the single turn, can be a little fiddly, but usually quite easy

Just a bump. Still have stock ready to ship here These will always be in stock too.

This diver sets up great, live the beam suppression feature. Will be using more in the future.
