Seed Counter 2nd prototype

Building 1

We have been testing hardware and developing new software for our prototype of seed counter. It’s been a while but after all, we have come across of what we think its a much better solution.


The old seed counter prototype had a major problem and was that the counter itself was not reliable enough. Most of the time would work good but some times would pick 2 seeds instead of one. That was because all the seeds where piled in the deposit where the rotating wheel would pick the seed. When the wheel of the seed counter rotated to pick a seed sometimes would pick more than one or even throw all the seeds right above the one that got picked. Continue Reading →


Arduino ethernet, the great internet of things

It’s been a while since I had the idea of an Arduino receiving and sending data trough the Internet. Long time ago I picked up a simple RGB led, an arduino Ethernet shield, put some pieces of code together and I was able to receive information from a website and convert into light and colour.

I built a custom XML parser for Arduino ethernet and some simple functions for changing the color and fade the leds. Just enough freedom to decide what information gather and how to show it. Colors, blinks, fades. All I had was just an RGB led, not even a button. So the interface was pretty simple.

‘Perils of Obedience’ Performance in two acts

Obedience to authority: human capacity for cruelty. If an authority allows us to break the law and even across the boundary of our morality, we feel a propensity to do so, as attempted to shown by the psychologist Stanley Milgram in 1963.

Perils of Obedience was an interactive dance piece that first took place at the “Fête de la musique 2009” in Paris, France. It is a generative audio and dance re-enactment of the Milgram Experiment.

Basically, the show is a dance exploration of institutional and cultural power systems, where an audience member gets to have direct influence on a performers actions. It asks the questions, how far would an audience member go, given the power?

Encounters with Arduino workshop

This is the first time we are presenting this modality of arduino workshop as “encounter with Arduino”. The first of a series of encounters around the globe and the first experience we are having organizing an event like this. The encounter is presented as a free and open event in which participants bring their own ideas and build their projects, alone or in groups, no matter if it’s the first time you see an Arduino board or you have been working with it for years.

As initiation for those whom are starting for the first time with Arduino, there are a series of examples to build in order to understand the interface, the hardware and the way of programming. These are easy yet functional prototypes that can be built with the components included in the KIT of the encounter. Among these examples we can find projects like: Virutal traffic lights, Light meter, Quichen countdown clock, IR receiver, …

New encounters will follow in Holland and Spain, stay tuned!

Below you can find all the information about the encounter with Arduino in Cordoba, Argentina. Continue Reading →


Seed Counter Project

Months ago I received a proposal to build a seed counter project together with somebody for an internet seeds seller. I would take care of the electronics, design circuits, electronic parts and software of the controller. The other person would take care of the physical layer, building the machine itself, manufacturing the pieces assembly and the mechanical logic behind it. The intention was to create a machine able to count seeds of different kinds and automatically place them into plastic blisters ready to ship to customers. So it is actually an invention from scratch. We need to think about how to do thinks, how to control the parts to do the things we want, and put them all in place so they will work as they suppose to. In essence it is building your own mini robot. You give him a way of thinking and a body, and he needs to do the rest by itself. A piece of art with artificial intelligence.
