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.
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.
