During the last MakerFaire Hannover, I found the very nice RGBDigits by Coen de Bruijn. I purchased the clock shield with 4 RGBDigits and a real time clock.

Finally I programmed some patterns for the NeoPixel rings.

Unfortunately the colours are not as bright as in real life.

The description of the patterns is below:

Now I have a small house connected to the world. Normally its a house to be illuminated by a tee light. Now it is equipped with an 8mm WS2812 LED. The LED is controlled by an Arduino (sketch), which is connected with a USB cable to a Raspberry Pi. On the Raspberry runs a little Python program, which gets in regular intervals the actual colour from cheerlights. The world can change the colour via a tweet, e.g. “#cheerlights green”.

As an eye-catcher for future MakerFaires and other events I tried to create the logo of the Arduino Group Hannover in 3D. I have no 3D printer at home, and the printers I know are much too small.

Now – that I get a little comfortable with github – I will put some of my Arduino sketches onto my github account.

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.

Here is a little enhancement for the Cheerlights sketch. I’ve attached a servo, which shall ring a little bell. Alas, the servo is to slow to have a hearable effect on the bell – the sound of the servo is louder than the ringing of the bell.

For the Christmas tree I wanted to have a light controlled by the community via Cheerlights. Unfortunatly the RedFly shield had lots of problems, so I activated my Raspberry Pi, which lay around for have a year. The Raspi installation had no problems; Raspbian, Ethernet with DHCP, Wifi with fixed IP.

The WingFly shield from Watterott lets you screw cables onto the Arduino instead of sticking them into the headers. This is very practical for prototyping.

 

WingFly Shield

Just soldered: compass modul LSM303DLHC, 3D compass and accelerometer. From Pololu, ordered at Watterott.

I will need this for my Steampunk outfit.
