How about just a simple RECOM DC/DC. Very small, cheap. I attach the in/out and ground and shrink wrap it. Couple of different ones available based on input voltage. www.digikey.com http://search.digikey.com/us/en/prod...038-ND/2256218

What makes it crap..so i can continue to look for one..and know what to look for?
Noisy, spews RF across a very broad band and has a high switching residu.

Sander, what would you use to step down from 4S to 12v?
A 12V linear regulator, as that can't add noise by design.

could you provide a link to one I can purchase...that YOU would use?
Personally - I use this one... seems to work well for powering both my 5v Lawmate and my 12v camera.

EDIT - NOT GOOD FOR 4S regulation to the camera unless your camera is 5v... otherwise it's simply a pass through.

Type uA7812 into Ebay and hit search: http://www.ebay.com/sch/i.html?_from...All-Categories
If you want a low voltage dropout, use a uA78m12: http://www.ebay.com/sch/i.html?_nkw=....c0.m270.l1313
The latter (uA78m12) is more preferable as it has the least voltage drop as the 4S pack nears 12V.

If it is broken, fix it. if it isn't broken, I'll soon fix that.
