More Seoul music

Filed under: Woodworking — thefusionguy @ 5:36 am

This is a wall-mounted version of the Korean gong/alarm clock that I made for our own bedroom. It definitely works–wakes us up every morning! The electronics use an Arduino microprocessor to time the on and off cycles for the gong actuator. This way the duration of the gong pulse and the time between pulses can be easily controlled. Now the pulses get stronger and the time between them, which starts at 30 seconds, gradually gets shorter. But so far, one has been sufficient…

One tricky part was getting the actuator wires to the gong, as I didn’t want the wires just hanging down. I ran the wires behind the drywall, but you can see a couple scars in the drywall I haven’t fixed yet. Will do.
