I use a Nabaztag/tag, but either the Nabaztag or Karotz will be fine for this, as we don't delve into the more complicated communications.
This is based on the Teensy 3.1, but virtually anything will do. In fact, if you're familiar with BeagleBoneBlacks or RasPi's and plan on doing advanced processing or communication (audio, bluetooth, wifi), use that, as it'll make your bunny way more powerful.
I used addressable LED strip (WS2811), but plain old LEDs will work fine if you just want them to turn on and off.
H-Bridge and Breakout board.
To control the motors, you need an H-Bridge chip. I use an SN754410 to control both motors. It's also good to get a breakout board for it so you don't have to solder directly to its pins.
Headers and sockets.
These are small and break into perfect-size pieces to fit into the existing plugs.
Hacker's screwdriver set.
The first set of screws you need to take out need a triangle screwdriver bit; the rest are all regular Phillips screws. I highly recommend this set as an excellent addition to your kit, if you don't have one already: http://www.ifixit.com/Store/Tools/54-Bit-Driver-K...
We're going to be connecting lots of I/O devices, so colorful wire is highly recommended to keep track of everything.
2 x 150 ohm
2 x 10K (or something within 5-20K range)
USB Micro cable.
Power/data to the Teensy. It's gonna be permanent, though, so make sure you don't mind sacrificing it for the project.
- Soldering kit
- Electrical tape
- Wire cutters/strippers
- Heat shrink
USB phone charger (Optional).
If you want to make your little guy portable, get one of these "lipstick" batteries. You can find them at best buy and even some drug stores, but they're cheaper online: http://www.ianker.com/product/79AN3K-PKA
If you like to test stuff out before hard-soldering anything, a prototyping board can be very handy. Line your Teensy with header pins and stick it in, then remove it when you're ready to build it.
To use my code, you need:
- Arduino environment
- Teensyduino driver
- Adafruit Neopixel library
