Gakken Theremin Kit Hack

Step 4 Drill and install

Drill a 1/4" hole in the back of the theremin just to the right of the speaker. This will be for mounting your audio out jack. I found holding the panel in place where it should be helped me to drill it on target. You should not do this. Always clamp things down and be safe when working with power tools.

Once you have your hole drilled, mount and fasten the jack in place.
