Ratsberry Pi! #piday #raspberrypi #ElectronicHalloween

This great Ratsberry Pi was posted up too late last year for you to build your own– now’s your chance! Control a bunch of servos with a Pi — check out our tutorial as well! From HariEdo:

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
