adventures in circuit bending, diy electronics and experimental music

Spanish Tiny Touch

This a variation on a circuit bend I’ve done several times before, the Vtech Tiny Touch Phone, which speaks numbers & shapes and nursery rhyme melodies. This one is a Spanish / English speaking version I’ve housed in an old Firewire hard drive case with the addition of a 5 step pitch sequencer and fuzz overdriven through a preamp circuit for extra dirt and warmth. The LED’s from the original toy which flash in time with the audio are mounted behind the 5 oval ventilation holes on the front. The 3 silver posts at the back (desk drawer knobs) are used as touch controls to control pitch for greater expression. The combination of the original circuit and the additions produces a large combination of possible sounds.
