Greg’s Harp is a new string robot I made for my friend Gregor. After the Pythagotron which is a single stringed bass roboter, this is my first attempt to combine three string units to make a polyphonic instrument.Continue reading “Greg’s Harp”
I’m making a new version of the ElektroCaster and want to share some insights into the process. This post is about the new LEF (light emitting fretboard).Continue reading “ElektroCasterV2: Making a new light emitting fretboard”
I used optical fiber to build a flash extension for doing macro-photos.Continue reading “My flash extension for doing macro-photografy”
“The EBow is a battery-powered electronic device for playing the electric guitar. The EBow uses a pickup – inductive string driver – feedback circuit, including a sensor coil, driver coil, and amplifier, to induce forced string vibrations. The EBow is monophonic, and drives one string at a time, producing a sound reminiscent of using a bow on the strings.” (Wikipedia)
Back in 2015 I made the Pythagotron, a one-string-bass-robot which turned out to be a really nice sound mashine. Now I’m doing a polyphonic version of it. To achieve this, I had to find a more elegnat way to build a single string-unit and combine multiple ones of them into one unit.Continue reading “A v-slot based pitch actuator”
I’m working a new instrument for a fellow band colleague – my first comissional work.
After six weeks of intense work, this self-built guitar with a led-fretboard is ready for action. Continue reading “There she hangs!”
Pythagoras of Samos was a man with many hobbys. I know him for his experiments with strings and their musical properties. Thats why I call this robotic string instrument “Pythagotron”.
-2 octaves of pitch range
-fast and precise intonation
-4 actuators for striking, muting, punshing, damping and shorten the string
-modular and parametric design (OpenScad)
-most parts are 3D-printed or easy to gather
