I’ve got a small project for someone, and I would like to see who is up to the challenge. I’ve got a small data center, and I’ve seen our cooling costs explode with the amount of servers we have added recently. I’d like to be able to take advantage of free cooling at night (when the air is cool) but using an electronically adjustable louver door and a set of fans. I am basing this project (for the fan control) off of Alan Parekh’s idea for a PMW fan controller based on temp.
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.
