Magic Power Co. Skull Doorbell (Unique Audio Model)

I managed to accidentally blow up the H-bridge (set of transistors that allows a motor to run in two directions) on the board that controls the tongue, but as you can see from it working in this video, that has since been dealt with.

I fixed it in a really stupid way, though. I used part of a spare board from a pumpkin doorbell that I had scrapped a while ago. (For some reason I've had like 4 of the pumpkin ones, but two of them were scrapped for parts) I removed the main IC from the pumpkin board, and hotwired the H-bridge from that board to the skull's IC. So now the thing has two boards in it. I really should have just pulled the transistors from the pumpkin board and replaced the skull's transistors, but it has those teeny tiny SMD transistors, and I HATE micro-soldering.

At least the thing works fine now, though.
