Re: Cheap replacement for the Power Distribution Board
Just listening in, you could use 2 of the standard robot batteries in series, use 1 for primary power and series in the second one with the hot only connected to the cRio. For power flux, you could use a large capacitor or a group of smaller ones in parallel (>20,000microF Should work). This would offset the instant V-drop from the start or reveres of motors. (The primary 12 might drop to 8V and the secondary battery in series won’t be affected so it should output 12. 12+8 =20) That is within minimum operating specs for the voltage. Easy, 2 batteries, a few caps that can be found lying around or in power supplies…. It’s a bit jerry rigged I know but it looks like it should work.
p.s. The "secondary" battery would not need to be a full sized FRC battery, it could be any 12V, a smaller one would be a lot easier to fit in.
