Sketching with Hardware exclaims:

It’s time for madness – MIDI Madness!

So our answer is the MidiMassOrgel (MMO).

  • MIDI – Musical Instrument Digital Interface
  • Mass – In our case not really a Maß but at least a beer crate is used.
  • Orgel – An instrument that produce sound by channeling wind through pipes.

All this components combined create an instrument with monumental sound*!

(*That it could have, if the double action hand air pump would not be so noisy ;))


Team 4 – OctoRocks

Brief Introduction

The Project OctoRosk is to make the styrofoam octopus playing the octagonal stringed musical instrument following the signal from MIDI (Musical Instrument Digital Interface) input. To be specific, under the eight feet of foam plastic octopus, eight servos fixed with guitar picks were installed and were used to pluck strings follow the signal from MIDI.  Our purpose is, while the instrument could produce the real note following the MIDI input, it could also entertain users.


Team 8: C-3PObstler

Published on: August 9, 2016 | Author: Ha-Vy Ha | Categories: 2016b, Best Projects


On the first day of brainstorming we tried to associate things that we would do outdoors with the challenge. And drinking games that require some skill like flip cup, flunky bad and beer pong came to our minds. We decided on beer pong because we initially thought about doing moving cups, that would rearrange when scoring. But then we decided to omit the teamplay aspect of the game and change it to a one player game. After gathering some ideas C-3PObstler was born. Or the idea of him at least.

A robot butler that would pour you a drink when you hit the cup.

1.Building a peristaltic pump

How does it work?

A peristaltic pump is a mechanical pump that can move fluids, by applying pressure onto the pump and basically squeezing it. The fluid is in a flexible tube inside a circular pump casing. A rotor is  attached to (in our case) 2 round bearings, which squeeze the tube, while turning with the rotor, which causes the fluid to move through the tube. And when the pressure point is released (the tube is open again), fluid flow is induced to the pump. (

Mouse Catch

In little time we decided to have the paper chasing tested by quickness and agility. After we sat down and let our creative juices flow it was clear that we would build a car. But not only a car. It would be prepared to look like a mouse. You have to catch the mouse.

Confuseball – Team 6

Published on: April 19, 2016 | Author: Sandro Gauß | Categories: 2016a, Best Projects, Projects

Since we’re both big foosball fans, it didn’t take us a lot of time to decide what to implement on this years topic „Circuit Board Games“: A foosball game 2.0

After doing some Brainstorming we decided that our foosball game needs to have two main features. The first and most important one, is the electronic goal counting. We solved the problem with a closed current circuit. When the ball hits the goal, the current circuit will be open for a short time. The Arduino recognizes this change of the circuit and sends a signal to the Android smartphone, which counts the goals. Furthermore the Arduino sends a signal to the green LEDs above the goals, which begin to flash for five times.

At the very beginning of the practical course we gathered a very basic knowledge of electronics and experimented with some bread boards. We lighted up some LEDs, added a switch and learned how to solder. The highlight of the first day was the keyboard hacking, where we built our own controller for browser games.

Watch the project video:

The dog days of summer – usually you should definitely be relaxing during those high summer weeks, especially in a scorching hot year like this. But on the other hand, we where stoked to get into the Sketching with Hardware course at the Faculty of Media Informatics.

Let me tell you why: First, i prefer binging through some days and nights of Arduino tinkering, wood-crafting, hot solder action and low-level coding, instead of learning a fixed quota for a test every week during a whole semester. Second, the atmosphere in the course made us feel like hanging out with some good friends and creating something unique. I mean, this course will leave an impression and gave us some good problem solving excercise as well as an improvement to our team working skills.

Finding a suitable “old thing” to work on:

To find an interisting “old thing” to work with we chose an object-centered approach and started to think about antique objects that changed over the years but are still irreplaceable in today’s modern and connected life.

One of the first objects that came into our minds as we heard the topic “Internet of old things” was a lamp which your grandma could have owned back in the days – something like the lamp we drew into our sketchbook:
