building a computer

[glatt]

My brother gave my son a Rasberry Pi for Christmas along with a circuit board that can control motors. They powered it on and ran it for a while downloading software and then smelled a slight smell of smoke. My brother touched the processor on the motor control to feel if it was warm, and he burned his finger. Pulled his hand away, and actual flames shot up from the control board's processor. (Small ones, but real flames.) Turns out he had ordered the wrong motor control circuit board to go with the Rasberry Pi. The smell was pretty bad and his finger hurt for a while, and he wound up buying a new different motor control board a few weeks later and sending it to my son.

My son hasn't tried out the new board yet.
