Halfmoon switch for Nord HP4

post image

The Nord HP has a nice switch for controlling the leslie. It is also possible to connect a half-moon switch to the pedal (control) input to have a simple slow-fast toggle switch action. Now, in order to have a more traditional slow – stop – fast three-way half-moon Leslie(r) switch, I made this tiny midi-controller.Read more

Arduino Music

post image

Three examples of musical Arduino’s. The first one is using a MIDI-shield as MIDI-mapper for connecting an XBox360 drum kit to an AKAI MPX8 sampler. The middle one is a stand-alone Auduino granular synth, using 5 potentiometers on a proto-shield. The last one is an Arduino Leonardo which works as USB-MIDI device, taking signals fromRead more

Robotic Desk Light

post image

Two IKEA lamps have been sacrificed for this robotic desk-light. The footplate was part of a standard black desk-light, the red cone comes from a different design (IKEA Fryebo). The arm consists of five dynamixel servo’s, inside the cone a 16LED neopixel ring light has been mounted. The arm is controlled using a combination ofRead more

Solder fume extractor light

post image

Very simple addition I should have made years ago. Of course, solder fumes are never nice at best of times, but having a clunky black humming extractor in your face is also something you might be inclined to neglect. Especially since it blocks out a lot of light you need on your soldering work-piece. HenceRead more

Micro Arcade Machine

post image

Adafruit’s cupcade and retro-pi gaming consoles are great fun! In my version I didn’t use their kit but built one from scratch, using the template drawings supplied by adafruit (for customising the look of your cupcade) and instead of the clever PI interface board, I used the electronics of an old HP USB keyboard whichRead more

Xbox 360 drum controller as MIDI device

post image

A recently acquired Xbox 360 drum controller proved to be one of the easiest retro interface designs ever. The setup comes standard with a MIDI out! In order to connect it to an Akai MPX8 sampler, a slight re-mapping of MIDI note numbers (can also be done in the sampler) and adjustment of velocity levelsRead more

Arduino case

Finally a very useful Arduino case design: small, sleek – and it allows for placing shields as well. Cut your own (with a fretsaw or lasercutter) using the following template: pdfRead more

Guitar hero as -standalone- MIDI device! Works on iPhone!

post image

The world has seen some versions of the guitar hero controller used for live music. Most versions included a MAX/MSP patch or other software running on a computer. In this retro-interface I’m looking at a different option, connecting the guitar as standalone USB MIDI device, so it can be connected to iphone directly! Check outRead more

Ex-libris stamp

post image

Trotec Laser cutters are originally designed for cutting stamp rubber. A logical follow-up is to design the mechanical bits (read: wood-block) using the laser cutter as well.. With this design on the plate (image mirrored, of course) – which has been adapted from an old book on ‘wonders of technology’. The rolling stamp is 20Read more
