Okay, that's how I did it anyway. I was wondering if different grounds were needed but obviously they are not. So that is not the problem. I was especially carefull not to connect different positives together , since so many people told me NOT TO. I wonder what happens .... the battery dies? Explosion?
Most of the circuit seems to be working but I don't get the computer to identify the programmer ... (the pins are correct)
Also the voltage regulator ... I know that excess voltage ( 5V from 9V ) is turned to heat ... but how much heat exactly? When I try to touch it it is burning extremely hot. As hot as an oven stove or something. I guess that it is made to withstand heat, but I was wondering how come the plastic did not melt evne after leaving it on for 5 minutes.
