Another nice example of the V-Tech Alphabet Apple. Glitch button, Pitch control, and reset switch added. Lovely random Analog sample and hold craziness, listen here.

Simple keyboard/drum machine with downwards pitch control. This is one of the first 'toys' I have seen with surface mount components instead of the usual larger resistors/transistors/capacitors etc, making it a bit fiddly to solder! Audio here.
2nd version of the Super Concert animal keyboard I have done. Downwards pitch control, glitchloop threshold control with momentary on button, reset button, and light dependent resistor with on/off switch. Mayhem here.
The original toy is basically an alphabet desk with a keyboard attatched! The bends are 'always on' and consist of a pitch knob and a light dependent resistor, the more light the lower the pitch. Works best in a darkened environment. In a light environment no sounds are generated until you cover the light dependent resistor. Audio here.
