Converting a Chinese Digger Toy to Use a Raspberry Pi Zero and PS3 Controller

via John Graves Tech Blog

This is a quick blog to explain some work I’ve done to convert a remote-controlled digger to use a Pi Zero, Dark Water 640, PS3 controller and a few other odds and ends to make a SUPER DIGGER!

My five-year-old son loves to play with construction toys.  I’ve purchased several Bruder brand trucks and they are great!  I envisioned someday modifying them to be remote-controlled.

I knew I wanted to use the Pi Zero.  I played around with some Arduino devices, but I like having the full control a Pi gives.  And, the price of the Zero is great!  But, I needed a reasonably priced motor controller to handle all six motors on the digger.  Fortunately I found the Dark Water company in the U.K.

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
