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
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
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
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
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
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
New A4 flat-kit design: a 18-servo 6-legged hexapod. It does not walk (yet) but servo control works and the mechanics look good: All parts can be cut from a single A4 sheet of acrylic glass. Other parts include 18 miniature servo’s (selling for 5EUR as TopLine mini-servo ES-05 JR (at Conrad Electronic)) and an ottantottoRead more
Using a telephone retro-interface and Arduino wav-shield-derivative a box has been build which allows you to use an old rotary phone as standalone dial-a-song system. This makes an excellent CD-pre-listening device for our CD-sales stand at concerts. The system is fully documented (including schematics, software, PCB layout) on the wiki. Although numerous designs have beenRead more
As presented for the first time on FAB6, using a Sharp gp2y0a02 sensor the flatpack-walker just got a little bit smarter. As long as the distance sensor is triggered, the robot walks backwards. The code is still pretty simple:

For a public display a beautiful LG HS200G LED beamer has been used which can play from USB data sources. However, no autoplay – autostart function was included. The beamer has been connected to a power source with timer switch. However, somebody still needs to push the on-off button, go trough the menu etc.. TheRead more
