‘Duckietown’ is an Open-Source MIT Class & Computer-Vision Self-Driving Robot for #RaspberryPi
Not only are the Duckiebots amazing to watch but their entire build specification, and even the specification of the layout of the ‘towns’ they drive in, is completely open-source and expanding in design and implementation at the Duckietown website hosted at MIT. Using a common camera module for Raspberry Pi 2 in conjunction with rviz software, the entire robot build and subsequent curriculum for teaching with them are available here; note the links are Google Docs (with some being edited online while I am typing this!) with ‘static PDF’s of the latest available edits also available for teacher-types looking for static content.

Adafruit 16-Channel PWM / Servo HAT for Raspberry Pi – Mini Kit: The Raspberry Pi is a wonderful little computer, but one thing it isn’t very good at is controlling DC Servo Motors – these motors need very specific and repetitive timing pulses to set the position. Instead of asking the Pi Linux kernel to send these signals, pop on this handy HAT! It adds the capability to control 16 Servos with perfect timing. It can also do PWM up to 1.6 KHz with 12 bit precision, all completely free-running. Read more.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
