        <description>March 2009 Build Project

We decided to build a few desktop spiffchorders and document the process to make it easier for folks to build their first chorder. 

Eventually this page will contain start to finish photos and instructions for making a desktop spiffchorder in an old vhs cassette case.
Currently, it has some photos of the process.</description>

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.</description>

- What exactly is the SpiffChorder?

The SpiffChorder is an implementation of chording keyboard Chorded keyboard.  It is an input device where characters are typed by pressing multiple keys at the same time. It was designed to entirely replace a computer keyboard.  Specifically, the SpiffChorder consists of the hardware and software needed to emulate a conventional usb keyboard in an object or objects with only a small number of keys or switches on it.

A few general notes

As a general rule the spiffchorder is using the standard key-bindings were possible.  This is a benefit as most of you are coming to chording already familiar with the QWERTY keyboard.  As such prefixing a chord with</description>

        <description>Twidlette chordset

The idea for the Twidlette is to use the thumb only for modifiers like shift, alt, esc, ctrl, number-pad  and use the fingers for everything else.

        <description>Using the ATmega8

If you build your SpiffChorder with an ATmega8 instead of the ATmega168 you will need to make one or two changes to the Makefile.  You will also need to  set the fuses differently when you program the chip.  All these changes are documented here.</description>
