HTV Inferno, a cheaper buck driver for reds?

[Pontiacg5]

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

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

low battery warning, decent efficiency, looks interesting!

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?

Pretty nice, I like the low charge indicator outputs.

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 :/

Thanks BB. :beer:
