I made this as a cheap and easy answer to the Rassilon1 brass sonic. Its made from brass pipe fittings, brass tube, and the sound is provided by an earbud speaker attached to an Arduino programmed ATTiny85. Its the same program that VapeBlade wrote for his custom screwdriver. I just lowered the tones and slowed it down a bit.

Metal Doctor Who Sonic Screwdriver with Arduino
I made all cuts and did all grinding and sanding with a dremmel. I hand filed it to a smooth finish. Then I weathered it with a scrubbing pad and added some small dents and dings with a hammer. I wanted it to look and feel used.
