Default (New) Can someone please build me a driver..

I need a driver to power a 4W 808 IR diode... preferably with a potentiometer..

Please reply with information you need from me... because that blatantly isn't enough ^

The uttermost extreme dimensions would be 8cm length MAX and 3 cm width MAX, the height would be 1.8cm MAX.

It would be powering a C-Mount diode.

That's easy if it can really be that big. Also - what kind of range do you need on current with a potentiometer?

I can probably do this pretty easily.

You can do a range of 0-∞ but it will be touchy, so name a range

Well I'm going to try some crystal alignment so I would like probably like 3A - "Whatever that diodes operating current is" What would the current be to power a 4W diode? It doesn't give you specs when I look on ebay. (laserlands)

Would a P3 Flex work for you? I think it fits your dimensions.

Can a P3 deliver the amps and voltage needed to power a 4W 808 diode

Hmm. Well, I could probably give you a decent range of anywhere from 2-3A to 5-6A. Not sure what the specs are on the diode though :\
