Bill Of Materials
There are no rare or expensive components in JasperMIDI. All the items can be obtained from the
usual electronics components suppliers. No special tools are required to build JasperMIDI – just
the usual soldering iron, solder and side cutters. If you wish to program the ATMega328 yourself,
then you will need an AVR compatible ISP programmer like the USBtinyISP.
