Hello folks, hopefully a simple situation for you to help with. I was debugging my Pythagoras build and noticed all the spots where there ought to be +3.3v were only showing +0.3v.
So I start poking around the power regulation section and find the L78L33 is too hot to touch, which...seems not good for a bunch of reasons.
Am I right in thinking that there ought to be ~9v DC at the input, a transistor which *isn't* too hot to touch, and a lovely regulated +3.3v on the output? Given the finger-searing hotness, have I got a dud regulator or is something upstream pushing it too hard?
