The Jam Jar is a small light-responsive digital synthesizer made out of a couple of dollars worth of parts and housed in a jam jar.

In this video, Yann Seznec, aka The Amazing Rolo, shows it off and makes some music with it, using Ableton Live and a guitar.

This video documents modding a Yamaha CS01 with a Highly Liquid Midi mod.

The kit was shipped quickly and was easy to put together. For those of you that have a CS01 and are handy with a solder iron I highly recommend the conversion.

The Shoe-thesizer is a two oscillator synthesizer with a filter built into an old Converse All-Star shoe:

The synthesizer circuit is based off a circuit (WSG by Ray Wilson) which uses three schmitt triggers. One for each of the oscillators and an extra for modulation. It also uses an op-amp to make a simple, yet effective, filter.

In the tongue of the shoe, there is a piezo transducer which is set up in parallel to one of the oscillators causing the voltage to spike, giving the synthesizer some cool rhythmic sounds. There is a switch that allows you to choose one or both oscillating frequencies to be mixed in to the output. The knobs were placed where the shoe-lace holes are and the output jack was placed in the toe area. I built this circuit during my freshmen year of high school for a science fair.

Trying getting this through your next TSA security check.

Adafruit’s Limor Fried demos a project to create an inexpensive wireless MIDI system. This could be used to hook up something like Processing/PureData/Max to a MIDI device.

You can read the details on the project at the LadyAda site.

Not sure what you’d call this noise thing….but it looks dangerous.
