musical instrument project

This week I made a pickup for a musical instrument. I've always wanted to make a pickup from scratch. Electronics interests me but I'm not very good at it. I thought this would be a way to try and start to understand the principals better. As far as I understand, to make an electromagnetic field that is needed to generate signals to make sound, the copper wire needs to be tightly coiled around a number of metal cores, sandwiched between two pieces of non-conductive material and sealed off at the sides so that the tops of the metal cores are the only parts exposed.
used a hacksaw blade to cut up the back of a broken picture frame

items: copper wire, neodymium magnets, bolts,

measuring. 4 strings is plenty.

cutting down the bolts (to about 3.5-4 cm).
the magnets connect to these ends.

tacking everything in place with hot glue

The pickup appears to be working but will probably need further insulation. I need to test it properly with some nickel or steel strings, which will happen as I build the rest of the instrument I guess...
