Motion detection to midi with puredata

another experiment with puredata, webcam image is passed through pix_movement object and a pix_blob turns the result into two midi note streams which are sent into reason via midi yoke. the image is the output of the pix_movement (difference between fr… Continue reading

First play with PureData

I was thinking about making a midi “harp” and thought of trying with a webcam, using puredata to analyse the images and generate midi/sounds. This is the first time I have played with PD and I don’t really know what I am doing with it yet… you’ll see… Continue reading

Pre programmed PICs

Following some requests, I have listed pre-programmed PICs on ebay for a couple of my projects. If there is much interest (and its not all a massive hassle) I might also look into getting some PCBs made up and putting kits togetherFor now here are the … Continue reading

POKEY sound chip experiments

The Atari POKEY was the classic soundchip in the Atari 8-bit home computers and many 1980′s arcade games. This clip shows some of my experiments in driving a POKEY from MIDI. A PIC receives MIDI data and two 74HC595 shift registers are used to assemble… Continue reading
