They´re back

For the occasion of Festpillene i Bergen 2010, a flock of Wind-up Birds has taken over the mountain side of the Fløien mountain. More specifically along the windy, steep path through the spring-green forest called Fløiensvingene. They will probably stay a few weeks. This has created a lot of buzz among the people using the path, so I will try to spend as much time as possible there to listen to audience reactions.

They might sound similar to previous generations, but there has been a few changes under the hood: The wood blocks have this time been milled instead of glued, making them more robust. Thanks to Ivar Bergseth and his CNC mill!

I use a new set of xbee modules, the xbee 2.4 pro digimesh modules. This gives a more stable network and is much easier to work with than the previous firmware.

I made new more practical circuitboards, which I got manufactured at BatchPCB, making the job of assembling the woody boards much easier. This was my first attempt at working with Eagle PCB circuit design software, but I leaned heavily on Roar Sletteland´s previous PCB layout for the first generation.
