Last year a NeoPixel ring with 24 LEDs blinked in our Christmas tree. I presented it on the last MakerFaire Hannover, but unfortunately it was too close to the Tesla coil on our booth, and it stopped working. To be prepared for this year’s Christmas I ordered new rings from Watterott – not one, but three: 16, 24, and 32 LEDs.
My wife prepared the lunch and had to defrost some spinach. So I decided to “help” her. I prepared the Raspberry Pi with the camera.
Two weeks ago, during the MakerFaire Hannover 2014, I bought the Useless Machnine from Solarbotics, which was sold by Watterott. Last weekend I began to assemble the machine. I read the construction manual, and started to build. But, alas, I used some old screwdrivers, so that I had to use strong force – too strong:
So I ordered a second one at Watterott, which arrived last Monday. Yesterday I bought some new screwdrivers at a hardware store, and continued to work.
Meanwhile: I should have read the complete manual; Solarbotics offers to send replacement part for broken ones.If they send parts to Germany, I will have two Useless Machines; you can never have enough of them.
Last weekend the MakerFaire Hannover 2014 took place, and the Arduino Group Hannover attended the Faire. Again Watterott was one of the exhibitors – it was clear, that this will be an expensive weekend ;-).
One of the things I bought was the NeoPixel Ring from Adafruit – a very nice toy!
In this article I will extract some of the documentation in the original neopixel library, so that I (and perhaps you) have it in one place without the disturbance of the actual code.
I’ve written a short article (in German) for the blog of the Arduino Group Hannover.
