For my midterm project I chose to develop a drawing machine. The following photo gallery shows my general process in developing a concept, producing a low-fidelity prototype in cardboard, and a final design in laser cut wood.
Low fidelity prototype in cardboard.

Laser cutting using wood.
Pattern using 40-36-100-50 gear set.
Alternative orientation using the 74 teeth gear.
Equipment:
- Laser cutter
- Plasma cutter
- Metal files
- Sandblaster
- Clamps
- Safety goggles
Materials used:
- Plywood
- 1/8 inch aluminum
- Variety of Dowels
- Rubber bands (for marker grip mechanism)
- 1/4 inch bolts, washers, nylon washers
- Markers
- Wood glue
- Epoxy (for wood to metal adhesion)
- 90 lb Card stock.
My total cost would be estimated from using two full 3′ x 3′ plywood sheet during my process – $12. A pack of dowels would cost about $2, with additional bolt/washers/epoxy/glue I would quote at less than $10. I sourced all my materials from the OEDK so had not paid out of pocket directly but a material cost total would end up around $22, with an additional labor cost of $80 in labor and equipment time, I can see this project adding up to over $100 to make.
