I took the awesome bus from ChaosCoreTech, lighted it and put the interior from CPT_Spekkie in it. The files are all sized to 85%, it was easier for me to print.
I put two AAA rechargeable batteries inside. The front lights are lighted with 3mm LED’s. The gear shifter is the switch for the light.
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.
