We have found the Raspberry Pi to be a cost-effective replacement for the Mac minis that we use in our office to drive TVs that are information radiators. We use these radiators to display the build status of our ci (continuous integration) projects. At ~$60 (Raspberry Pi, USB WiFi, enclosure), it’s 90% cheaper than using a $600 Mac mini….
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.
