I just got an Axoloti and it’s great

“Sketching digital audio algorithms with the musical playability of standalone hardware.”

With the launch of the Raspberry Pi (RPi) four years ago, I was quite exited about to be able to run my Pure Data patches on a small and affordable unit, to build my own little music mashines. This excitement was a little damped when I realized that:

Pythagotron

PythagotronPythagoras of Samos was a man with many hobbys. I know him primarily for his experiments with strings and their musical properties. Thats why I call this robotic string instrument “Pythagotron”.

It features:

  • 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
  • open source

An introduction to MuVisu

In this video I describe the current version of MuVisu, a program I’ve made to help learning musical instruments. It is insprired by interactive music games like Guitar Hero, Rock Band or Rocksmith. It’s focused on an universal approach of high customizabillity to make it usable for a wide scope of musical instruments as well as different learning-settings and -goals.

The project is hosted here: https://github.com/fpiesik/MuviTools/

 

My PCB-Milling-Toolchain

DSC01802

PCB-milling is an interesting alternative to the traditional PCB-etching method, because it doesn’t involve chemicals and the mill can also be used to drill the holes an cut out the board. I think i t’s also faster (never did etching). On the downside, the process is not easy to handle and it’s hard to level the surface of the PCB precisely to get a consistant quality of the traces. I haven’t enough practise to tell how fast the tool wears out and how the costs add up compared to the traditional etching method. But I finally managed to get nice results from PCB-milling and like to share the setup with you by describing the toolchain I used. The tools are all open source, by the way:)

Catarina Mota (ted-)talks about open materials

A wonderful talk about smart materials and the maker culture.
I think it contains lots of well nailed statements.

“…There was a time when we understood how things work and how they were made, so we could build and repair them… Many of these do it yourself practises were lost during the second half of the 20th century. But know the maker community and the open source model are bringing this kind of knowledge about how things work and what they’re made of back into our lives…”
