HTV Inferno, a cheaper buck driver for reds?

Check this out, I found it while trolling through e-bay...

660nm red laser diode driver (HTV Inferno 2.11) | eBay

I think the "pot-mod" statement might just be a language barrier issue, it sure seems like he knows his stuff from the rest of the listing.

It looks hand assembled so I searched here for a bit but couldn't find anything about it.

Anybody have any experience with these? I'll offer to be the guinea pig if necessary :whistle:

That looks really interesting! Unfortunately, it's rather expensive for such a driver, though. You should buy one of these and check it out!

Cool find. I hope he decides to make these for other diodes as well. The future of the micro____ drives seems dim at best.

EDIT: I was thinking boost not buck. Ignore that statement.

All the bells and whistles look good but this kind of worries me: "synchronous step-down pulse voltage regulator"

I'm no expert in electronics but shouldn't we be using constant current regulators?

You can control current with those as well. They just regulate the voltage/current using switching in a bucking topology. That way you're not wasting so much energy as in a linear regulator. DrLava's Microboost uses a boost topology and it can regulate current just fine.

Nice find, the hobby is screaming for new drivers at the mo :/
