Hand-cranked MIDI sequencer from a baked bean can

One empty baked bean tin, some lego and a stack of little magnets… stick magnets on the tin and slide them about to ‘program’ the sequencer, then grab hold of the ‘transport control’ and crank away…. The breadboard contains 5 hall-effect switches a… Continue reading

MIDI Guitar on Stripboard… Kind of

Somewhere between the Omnichord and the Stylophone lies this thing… simple but suprisingly effective… a PIC16F688 microcontroller, 2 shift registers IC’s, 36 switches and a bunch of wire. The buttons select major/minor/maj7/min7/7/dim/aug chords ba… Continue reading

When Lava met Mopho

I got a new toy! an Mopho analog synth from Dave Smith Instruments. First use.. a companion to my MIDI lavalamp to free it up from PC based soft synths. Since my original MIDI lavalamp project was based on a standard Arduino, I decided this time to mak… Continue reading

Stylophone MIDI controller

A few months ago I used an Arduino clone board to send MIDI messages out of a Stylophone. I always intended to take it to the next level and get another Stylophone (preferably a broken one) and rip out the guts to fit all the electronics inside, and al… Continue reading

DIY Games Console

Another PIC project… this one using a 14-pin 16F688 and playing a version of “Breakout”. I might see if I can get a convincing version of “Space Invaders” to run on that 8×8 matrix too….Usual setup of 74HC595 shift registers (x3) and ULN2803 NPN tr… Continue reading
