1) Find cheaper electronics to use. I chose to use the Gogo Board just because it was the quickest thing available to me for my class, but it is quite expensive (~$100 with the display and relay) and a real pain to work with. Do you guys by chance know of an ultra-low cost board that could handle about 4 switches, about 50 lines of code, and control a LCD screen and a relay?
Redesign to eliminate the LCD. It adds a big chunk to cost and is not necessary. Then use a PIC16F1847 (about $1.00).

Solder it directly onto a board yourself, like this one (about $3).

If you insist on the LCD, then there's a comparable board for under $20, easy.
