I did something bad to one of my toy computers over the weekend - basically gave it a fuse setting that makes it require an external clock signal - and rather than toss it I'm going to try giving it a clock signal from another atmega328p for long enough to revert the setting.
Anyway, the best way I've figured out to connect to the clock signal is to stab a sewing needle through a stick, then rest it on the board, with the end of the needle poking the pin. Very low tech:
So the question is, what do people do for this in real life? Is there a standard tool for it, like maybe a tiny little claw to grab the pin or something? Specifically, the chip is a TQFP package with wee little tiny pins.
