5V and 3.3V power supplies

Don't think anyone's posted about these yet.
Thought I'd share something I've found on my travels. These little beggars are brilliant.
They're DC/DC buck converters with a wide input of 7-36V and come in 5V and 3.3V versions. They're capable of supplying 1.5A and the 5V model is capable of 90% typical efficiency. Ok fine not the best, but they're such a small form factor and require zero effort I thought they were worth a mention.

Came across them for work; two of them are currently powering 2 Ordroids, 2 webcams, an Xbee module, a GNSS card and two of our boards from a 3S lipo on a project that I can't really talk about... but we got over an hour's worth of playtime off it. Not bad considering everything it was powering.

For those of you that don't speak wizard, I apologise. These can be put in if you want to use something that needs 5 or 3.3V and you're running a battery that supplies more (practically every battery setup). They're a pretty good solution if you're in need of driving a Pi or Arduino etc in your blaster and don't just want a linear regulator to waste your electrons through heat, these babies won't need any supporting components for Nerf applications, and they'll be featuring in my more...esoteric mods when I get around to them.

We've been using these for a while now, and I can't recommend them enough.

Carry on!

Interesting, how would you select 5v or 3.3v? I just have to find something that uses 5/3.3v now.

Sorry dude, meant to say there are two different types, one 5v and the other 3.3v.
