Adding some funk to an old Vtech toy

The Scrounge

• it was the first weekend of reading week. the thought of the midterms immediately after the reading week was not yet a concern. lets take apart some electronics and mess with them, we said. a value village run ensued. a slew of various used electronics were acquired including most importantly: the vtech Kidi Star Dance.

• this toy had all the peripherals that someone in our position could want: speakers, buttons, an lcd, lights. lots of potential to express our funkiness after we were able to run custom code on it.
