Haha I am glad you like it!
Yes it was definitely inspired by the diddley bow, but in the name of DIY i really didn't want to use a guitar pickup, like jack white did. With a broken computer standing in our bands rehearsal space i realized there's a big coil in the power supply, and a couple of good strong magnets in the harddrive. hdd magnets have four poles so i cut them in half to make normal 2-pole magnets and stacked the 4 pieces making a good magnet for the coil.
The whole thing being plastic and my fingers being, well, flesh made for a very weak strumming sound. Remembering though that the pizzicato sound of a violin is muffled in a similar manner i decided to try bowing it, instant love!
