Control The Air Conditioning With Slack

[Raphael Baron] needed a better way to control his office’s air conditioning units. Sure, they have remotes, but that’s too easy. [Raphael] came up with a solution that uses an ESP8266, a computer, IR LEDs, and a bot that runs on Slack.

[Raphael] built a prototype of the ESP8266 hardware on protoboard and used it to read and record the IR signals from the remote. Once he’d figured out the issues he was having with the IR library he was using, he could use it to send the IR commands to the AC unit. Since their office has two AC …read more

DIY Lap Counters for Drone Racing

Drone racing is a very exciting sport, in which there is a lot of room for hackers and makers to add that special sauce into the mix. Usually the aerial finish line requires special race-timing hardware to do the lap counting, and there are timing gate transponders available for around $40. In his project CoreIR and CoreIR-Uplink, [Michael Rickert] decided to reverse engineer the IR Protocol that goes into these beacons and made a homebrew version that mimics the original. The transponders send a 7-digit number out repeatedly to a receiver at the finish line as the UAV passes by  …read more
