If you have read Sky Mall magazine on a plane, then you have seen the inspiration for the Sprintronic
This is a very easy, inexpensive, and quick
project. The clock's movement is a standard battery powered quartz movement from an arts and crafts store. Its case is made of inexpensive 5 mm (0.2 inch) plywood. The face lens is a small piece of Plexiglas.
The case and lens patterns were cut on a laser cutter, however neither are too complicated to fabricate using a scroll saw and drill. The face lettering can be transferred using the toner transfer method when cut with a scroll saw.
A complete kit for this clock is now available at http://www.dougparadis.com/products-page/clock-kits/sprintronic-clock-kit/
