Doorman Arduino

Doorman Arduino is an open source project that controls the doors of your house. It uses a network connection and an Arduino to accomplish this function. As in domotic appliances, the main goal is to be in control of all your entrances (main door, garage door,…). On top of that, our goal is to achieve this functions without the need of any specialized software on the client side. A web browser is the only requirement to be able to control all the doors.

Arduino Artnet sender keyboard for MA2

It’s been a year since last time I build a project for myself, just for fun. And I tough that I should finally build that old project that I had in mind long time ago but never had time to. I’m talking about my idea of converting and old PS2  keyboard into an Arduino Artnet broadcaster. People in the lighting buisness will apreciate the idea because we have alwas the need of more buttons more faders to control every single aspect of the lighting system. So this project extends our interface using artnet and on the cheap! The logic behind is very simple. We have a lighting system wich is composed by inteligent lights in one side and a control system in the other. Normally the comunicacion betwen both is done via a DMX cable. But many of the lighting controller nowadays have extra inputs in form of DMX inputs, MIDI, analog and/or Artnet. I will be using the last one (artnet) to, trough the keys of the keyboard, trigger functions on our lighting desk. In my case the GrandMA2 onPC software. Continue Reading →

Stepper motors and Arduino

Back in the 80s steppers where commonly used in most consumer products requiring precise control of moving pats. That’s why old printers, typewriters, faxes are a great source of still usable stepper motors waiting for somebody to give them a use.

Controlling Stepper motors with arduino have been always a good way of having things precisely positioned at all times. Their way of working is pretty simple, you send electronic pulses and the stepper motor moves one step degree at a time (hence the name “steppers”). So if we know how many steps we can do in 380 degrees we will know how many degree we move in one step. Then we can keep track of the position or angle of our stepper motor.

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?
