Robotics – Prototype #1
Since a couple of time I had in mind to continue with some servos, sensors and breadboards to build some robots, that soon or later will conquer the world Continue reading Robotics – Prototype #1

WIP: Brewery Part 2
After about 10 months of thinking, planing and construction work, we made it to day X, where we finally get the chance to test and evaluate the prototype capabilities of our „Reaktor“.
Facing a lot of diffuculties to get every part in place & all circuits connected we want to launch our first mashing project tomorrow in the afternoon.
So what is the perspective?
We want you provide with some reasonable documentation & information about the brewing process with its corresponding problems supported by photography & text.
You’ll have the chance to get the latest news out of our ‘Kommandozentrale’ on how we’re progressing and doing. Due to its complexity and the shortage of time this mash has to be considered as a rather unstable condition with a large possibilty of error and epic fail.
When getting up in the morning it felt like our project is not even going to start due to missing conversion of force from our VW scirocco motor to the stirrer shaft (which basically didn’t have any paddles attached to it.), the non existence of a perforated metal plate for lautering and more severly the non arrival of our malt order from 5 weeks ago. Just some of the practical problems we had to face, I was also working to get the microcontroller and it’s interface set up.
But with the friendly help of Stefan from http://www.gaestehaus-melcher.at/index2.php?show=hausbrauerei, my father and Stefan II we managed to get everything back on track.
At the moment last preparations for tomorrow are being made to make our Yeasts (Saflager S-23) even more happy! Sterilisation of our two 500 mL Erlenmeyer flasks and subsequent inocculation is undertaken right now. Happy Mating my friends!
You already noticed that I’m brewing beer with my friend Hannes. In the last couple of weeks I found some time to continue working on our ‘Reaktor’.
This is our work-in-progress boiler and it will be able to handle 30 l mash. A heating element boils ~16l of water that we use to heat up our mash indirectly. Two PT1000 heating sensor (I want to use 3 in the future) measure the temperature of the water and the mash, while a regulation (implemented in Processing) controls the process of brewing. Sensor data is been read by an Arduino that also controls the relay of our heating element. Currently we’re using 230V, 1.6 A to heat up water, but we also have plans to change the system to high voltage current, if we have to wait to long to heat up everything.
We are going to test our reactor this weekend and I will let you know what will happen!
Isn’t that cool? : )
Work in progress: Arduino powered Beer brewing machine
Well some of you already realized that every few months I am brewing beer by my own with my high school-mate Hannes. We’re changing our mixture every time because we want to test new sorts of beer and improve our own mixtures. While we were really surprised that even our first attempt was ‘drinkable’, our last one was even better.
Hannes used all his knowledge to build our own boiler which will be able to brew 30 L beer. While brewing beer it is important to stay at certain levels of temperature that we had to do manually in the past. In our boiler we attached temperature- & fluid-level sensors. Their data is being used by an Arduino to control the heating element which consumes up to 3.3k Watt (!) so we’re using a remote controlled electrical jack to control it.
Our prototype-interface has been implemented in Max/MSP which is used to send temperature & timing data to the Arduino, so that the brewing process can be run without an attached computer or any other interface. Sensor-data will be stored in a database for further analyses.
This project is still work in progress and we want to use our brewing machine (we call it ‘Reaktor’ …) in the end of September.
Below I attached one of my first Arduino-tests 😉
More infos soon & you can ask me for any further details 😉
Work in progress: Tian Dynamic Light Installation
This Autumn we will finish our dynamic light installation for Tian Restaurant, based in the heart of Vienna. Arduino-driven dynamic moving light-heads will decorate the chandelier and vvvv-powered visuals will add additional atmosphere on top of it.
Currently I am finishing the designs at Strukt of our vvvv-patches plus interface-interaction & design to control the installation via tablet.
The goal of our installation was to link virtual reality to our imeditate reality. If you loose the game, you have to endure the consequences.As a result of course „Interaktion im Raum“ we tried to combine a programmed game idea with real consequences. Everything was programmed using ProcessingIDE and an Arduino-board to trigger a ball machine aimed at the player.
The player controls the paddle within the game with our self created foot controller.Although the game is being played in a virtual reality, upon loosing the game, the player would have consequences in real life. The player has to learn that his reactions in the game will have consequences in reality. In conclusion when you loose the game, a machine will shoot the ball on you that you have lost; Virtual Reality becomes Reality.

Aetherophone: a Theremin written in Max/MSP using a distance sensor and some magic.
Simple technique, but quite impressive: A Theremin built with Max/MSP and Arduino plus a distance sensor. The lights are also controlled by the Arduino using relays. An additional tremolo-effekt makes the sound a little bit more interesting.
