An Inexpensive Persistance of Vision Toy
Originally this project was designed in collaboration with Marcos Ojeda as an easy-to-build demonstration of how microcontrollers work, for new freshman coming into MIT. The design priorities were: ease of construction, cost, and simplicitiy of design. The necessary parts, including batteries and a preprogrammed microcontroller, were assembled into a kit. 100 kits were made at a cost of $3.50 per and distributed. Assembly time for students with no experience soldering seems to be approximately 1 hour.
