Schizophrenic Zoot: Hacked Sesame Street Sax

Schizophrenic Zoot: A Sesame Street Saxophone made by Fisher Price. Originally, it plays the tunes "Rock Around the Clock" and "Yackity Yack" when the colorful buttons are pressed and is adorned with several familiar childhood characters which light up.Several "hot spots" on the circuit board can be crossed to produce various interesting musical sequences, some of which cause the pitch to modulate between extremely high and low registers rapidly, putting the schizophrenia into the Zoot. All of the interactive points on the board are made accessible through a breakout box containing potentiometers,photo resistors, and switches via telephone and CAT5 cables that connect to the instrument. The sound can be accessed through the internal speaker or through an installed 1/4 inch jack.

afterMath: HIGHLYLIQUID MIDI-retrofitted Speak & Math

AfterMath: A Speak & Math made by Texas Instruments is one of the more popular toys currently being "Hacked" by a growing community. Its unique voice synthesizer allows a vast library of speech phonemes to be accessed in real-time. Soldering on a retrofit specially created by Highly Liquid equips me with the flexibility to trigger the glitch points using MIDI. I use Max/MSP as my platform to generate the MIDI messages and am able to interact with AfterMath with my SAITEK X-45 flight controllers.

the WEMS: Wailing Electronic Musical Slinky

the WEMS: Originally as an "electronic talking musical slinky", it features several games involving moving the slinky to keep the lights moving while music keeps a beat and a voice gives instruction. Tilt sensors came with the toy to respond to its changing orientation. Attaching potentiometers, a photo resistor, and touch spots through a spiral telephone cable to interact with the clock resistor allows me to dynamically control its register during play. A tickle spot may cause the WEMS to glitch creating aleatoric noises.
