i intend to try making a simplex addiator

construction notes

materials
- laser cut parts of of acrylic, wood?
  - does two-tone acrylic come in sheets thin enough to make it useful for the numerals / colors?
- make out of sheet metal?
  - slides could be milled out of sheet stock - probably easier than trying to stamp them
    - could do them all at once
  - case might prove problematical
details
- engrave / stamp features & paint to color them in?
- turn a stylus, or just use pencil?
- make the zeroing slide push-operated and at the bottom of the device?
  - might make it prone to accidental zeroing, or to stressing the sliders when pocketed
