[Limpkin], aka Hackaday alum [Matheiu Stephan], is at it again, converting an IKEA lamp into a visual wake-up light. He wants to build an alarm that can be remotely triggered, He’s basing this project around a combination of an ESP8266 that handles the communication and timing, and a pile of 10-watt RGB LEDs. However, he is having a problem: every time he initializes the PWM (pulse width modulation) signalling that will control the level of the LEDs, his ESP8266 dev board reboots. So, he’s offering an interesting bounty for the person who finds the issue: figure it out and he will send you the lamp. Well, the PCB and components, anyway: you’ll have to add your own IKEA lamp. It’s an interesting approach to debugging a hardware problem, so feel free to take a look. The full hardware and software details are on his GitHub repository.
