The heat is on

Well, all the soldering is finished but I’ve got a bit of a heat problem. When I connect everything up with the Wiring board, the batteries that drive everything start getting hot, really hot, as in too hot to touch. When I let them cool down and disconnect the Wiring board, the buzzer buzzes and the lights glow. Bit of a major set back to say the least. I’m not sure if it’s because it’s shorting out somewhere or the power from the board is causing it. It’ll have to wait ’til the morning now…..which is only 3 hours away!
