An inexpensive musical toy was ordered from eBay. The purpose was to convert it to an auxiliary sound source. Each white key corresponds to a note or a tune depending on the pink switch in the lower left corner of the toy. The unit was disassembled to examine the circuitry inside. The entire board was contained on a strip running beneath the keys. The majority of the board was an array of switch pads. The pads were activated by a strip of silicone (probably silicone) with conductive contacts.
The rest of the posts for this project have been arranged by date.

Inexpensive musical toy
The simple insides
The switch which controls whether the toy uses notes or tunes was investigated. It was seen that the toy will operate as a note generator if the switch was removed since the switch was in the open position while producing notes. A list of important features found was written on the iPad and photographed for the sake of the blog.
