Hardware

punchtape.dxf has the basic mechanical design of the read head. The head is bolted together with M3 hardware.

boards/5mm-phototransistors contains Eagle CAD files for the LED emitter and phototransistor boards.

Software

The reader is implemented as an Arduino sketch in punchtape-reader/punchtape-reader.ino. I'm using a Teensy++ 2.0 at present but it should work with any ordinary Arduino variant. You'll have to alter the pin assignments at the top of the file, though.

Something went wrong with that request. Please try again.
