Not so much myself physically, but I certainly have written code that destroyed my own projects (hurt my wallet). Many years ago I was working on a mobile outdoor hobby robotics project (RoboMagellan) and had two glitches in parallel. One was the software controlling the robot, the other was in a microcontroller in the kill switch mechanism. The main computer was reset by a brown out which also caused the uC listening for inputs from the radio used as the "enable" switch to lock up (with the motors enabled) and I hadn't yet learned about hardware watchdog timers. Drove straight into a river.
