L7905 is a negative 5V regulator, you should be using a L7805 that is a +5V regulator.

That was it! I had them both on my desk and probably took the wrong one. Swapped them over and things came to life without overheating. It’s also able to control 1x 12v relay. It is suposed to be a temperature controled water heater so the bird bath doesn’t freezes. I’ll post that a little later as it uses a picaxe also.
