Almost ready to send the STL files out for 3D printing! Will have these done in Polyamide at Shapeways. There are three 3D-printed parts:

  1. Mount for TSL235R in exposure chamber [not shown]
  2. Connector housing for JST connector (between TSL235R in camera and the console) [Photo 1]
  3. Console [Photos 2 and 3]

This guy has already been sent to Fritzing Fab! It will be housing the bubble display, Trinket Pro 3.3V, a charger for the lithium polymer battery (110mAh), and buttons to change the ISO value and trigger a light measurement.
