-|{{spiffchorder:​2010.03.lc.ip.jpg|}}|| +Sunday afternoon project. ​ This right hand chorder uses the atmega168 chip.  It is built on a Radio Shack 276-150 printed circuit board which greatly reduces the need to run wires around. ​ It uses cherry keyswithches with replacement lighter weight springs. ​ It was used to create and edit this wiki page.
