Ratsberri Pi – a Hallowe’en project @RaspberryPi #piday #raspberrypi

HariEdo‘s Ratsberri Pi!

I found some squeaky rubber rats at the local dollar store last year. Of course I had to buy ten of them, and then work on some sort of project later. Once I got my Raspberry Pi, I knew I had to combine these into a Hallowe’en decoration project.

Recipe:
* 2S hobby lipo (2S4P in this configuration) for 7.4V
* 2x Sparkfun 5V/3.3V breadboard power regulator, modified to remove PTC fuses
* Raspberry Pi Model B Rev 1
* Adafruit Pi Cobbler GPIO breakout
* Adafruit 16 Channel i2c PWM Servo Controller
* 10x Tower Pro SG92R micro servos (via Adafruit)
* 20x 5mm Red LEDs
* 10x 330 Ohm resistors
* 10x 1 meter Futaba-style servo extensions (via eBay)
* 10x 6 cm Futaba-style servo extensions (hand assembled)
* 10x dollar store rat toys
* 2x solderless breadboards and a few wires
* USB micro B plug (chopped a USB plug) to power Raspberry Pi
* Hot Glue to form insulators and standoffs

Adafruit Assembled Pi Cobbler Breakout + Cable for Raspberry Pi – Now that you’ve finally got your hands on a Raspberry Pi®, you’re probably itching to make some fun embedded computer projects with it. What you need is an add on prototyping Pi Cobbler from Adafruit, which can break out all those tasty power, GPIO, I2C and SPI pins from the 26 pin header onto a solderless breadboard. This set will make “cobbling together” prototypes with the Pi super easy. (read more)


1411_MED

Adafruit 16-Channel 12-bit PWM/Servo Shield – I2C interface – You want to make a cool Arduino robot, maybe a hexapod walker, or maybe just a piece of art with a lot of moving parts. Or maybe you want to drive a lot of LEDs with precise PWM output. Then you realize that the Arduino has only a few PWM outputs, and maybe those outputs are conflicting with another shield! What now? You could give up OR you could just get our handy PWM and Servo driver shield. It’s just like our popular PWM/Servo Breakout but now Arduino-ready and works with any Arduino that uses shields: Uno, Leo, Mega, ADK, its all good. (read more)
