De meningen ge-uit door medewerkers en studenten van de TU Delft en de commentaren die zijn gegeven reflecteren niet perse de mening(en) van de TU Delft. De TU Delft is dan ook niet verantwoordelijk voor de inhoud van hetgeen op de TU Delft weblogs zichtbaar is. Wel vindt de TU Delft het belangrijk - en ook waarde toevoegend - dat medewerkers en studenten op deze, door de TU Delft gefaciliteerde, omgeving hun mening kunnen geven.

Lampan92 gets closer to reality

In a previous post, I had spouted endless technotrivia on how to connect an Arduino to a FoxBoard Linux SBC. As one German former student of mine, you could ask "but vy?". This is the why: building the world biggest networked computer controlled IKEA hack lamp. Soon to be installed in the central hall of the Industrial Design building at TUDelft.

The lamp is an idea of Daniel Saakes, brought into physical reality by Aadjan van der Helm, Aditya Pawar, Sterre van der Helm and yours truly, with the usual fundamental collaboration of Rob Luxen. This lamp is made up of 92 individual IKEA lamps, wired as 12 groups (corresponding to the faces of a dodecahedron), plus two more groups for additional lamps placed on the vertices and one group that contains one, solitary, bulb on the inside of the lamp. You can consider it a baroque evolution of the original Big lamps from IKEA Lampan lamps idea.

Here are some photos of the work in progress

This is the lamp at an advanced stage of construction. Notice that the caps are not yet on the individual lamps, and there is overall lumpiness. Not yet sweetly polyhedral.

after plenty of work, here it is, looking much better. Thomasz is inspecting the innards, perhaps a little too close for comfort.

This is the lamp, powered up, in its temporary hanging location in the basement of industrial design.

and a closeup shows the gnarly internal structure, and part of the wiring.

The lamp’s internal FoxBoard queries a service, written as a python server in the Google App Engine environment. The server produces a configuration message that contains the new state of the lamp (that is, which groups are on and which are off). The FoxBoard then writes out the message to an Arduino over USB: the Arduino, in turn, squirts it out to two shift register circuits that present their outputs to optoisolators. The optoisolators separate the low voltage side of the system from the 220 V side, and drive the lamps.

The system is built around the fundamental limitations of compact fluorescent lamps: they are not easy to dim, and they don’t like being switched on and off frequently. Hence, the configuration will be pulled infrequently, perhaps once every ten minutes.

The Google App Engine server has been built on top of my (currently in progress) SERPE service prototyping environment.

August brings five lazy links to interesting stuff.

In August everybody is lazy, so I will just publish three five links

  1. A fantastic periodic table of information visualization. Techniques organized to show their relationship, with examples for each one.
  2. You cannot innovate like Apple. Apple is the canonical example of all that is good in the design of interactive things. But it looks like their process is not something you can grab and apply somewhere else. Not unless you manage to clone Steve Jobs and a few other key people. More about it here.
  3. Ivan Krstić‘s blog. Cool guy, worked at OLPC, now is in Apple.
  4. Just so you don’t forget how nerdy I can be, playing around with ChucK looks damn good right now. Regardless of the fact that I have managed to pack my schedule full from now to Christmas. Anyway, it is a Strongly-timed, Concurrent, and On-the-fly Audio Programming Language, and if that does not get you excited, I don’t know what will
  5. Oh, and I was reminded -by the resourceful Saakes- of Hypershot, "the first digital camera for your data", very fancy rendering, apparently not too difficult to use. Maybe I will give it a spin inside Computer Visualization.

There you go. Enjoy your summer sun, if you are in the right latitudes and you happen to actually like unfiltered solar radiation. I am also including a gratuitous picture of happy users


this is what happens at TUDelft industrial design when there is a fire alarm: people rescue their laptops, stream out of the building, hook up to the wireless and continue work. You could argue that we don’t really need a building, just a lot of grassy knolls with some power sockets here and there.
