I thought the 12vt regulated power supply on the site was to connect the Rx to a 12vt battery. Instead it is a wall wart regulated to 5vt.
Actually it is a wall wart regulated to 12v.
How do I regulate a 12vt dc to 5vt dc without blowing the Rx?
The rx is 12v... actually 9v to 12v, and has a built in regulator so you've got some leeway on power. A 12v lead acid battery will work fine, as would an 8 cell battery pack. I personally use a 3 cell li-po pack.
The other question is what are you using to power the camera/transmitter combo? They are running from the same battery correct?
The camera and tx are both 5v so you can use the same battery. A 4 cell receiver pack would work fine direct, with no regulation.
