“From Ray Wilson, inventor of the Soundlab Mini Synth comes the Wacky Electronic Noise Maker Thingy. It’s a much simpler circuit, which produces surprisingly cool pulsing, bleeping type noises.

HOW TO – Build a telephone archiver tapping device

Parts You'll Need 1By using an old laptop, a home made chat-cord and some parts from an old telephone you can build a telephone tapping device. Add Atropos to the mix and you have yourself an telephone call archiving system that will save all incoming and outgoing calls.

Step by step instructions and and even a sample of an incoming phone call. Link. Might be good for podcasting.

Compass belt project…

Compass belt project…

NorthbeltSeems to me this would could be used with a GPS and low cost portable computer for the blind“a belt which enables its user to feel his orientation in space via vibrotactile stimulation. This belt is equipped with a set of vibrators controlled by an electronic compass: the element pointing north is always slightly vibrating. That way, the person wearing the belt gets permanent input about his heading relative to the earth’s magnetic field.” [via] Link.
