Absolute Overkill IKEA Lampan Lamp Hack

Absolute Overkill IKEA Lampan Lamp Hack

Sometimes too much overkill isn’t enough. [Jesus Echavarria] hacked an IKEA Lampan light for his daughter to add color LEDs, a timer, Bluetooth control over the hue, and a local override knob. The result: a $5 lamp with at least $50 of added awesomeness. Let’s have a look at the latter. The whole lamp system is based around a PIC microcontroller and WS2811 LED s for the color light show. Since the lamp was already built to run a 40W lightbulb, and [Jesus] wanted to retain that functionality, he added an SSR to the build. Yeah, it’s rated for 5,000W, but it’s what he had on hand. Next comes the low-voltage power supply. [Jesus] needed 5V for the PIC, and used the guts from a cheap USB charger as a quick and dirty 5V converter — a nice hack. To power the HC-05 Bluetooth module, which requires 3.3V, he wired up a low-dropout voltage regulator to the 5V line. A level-converter...
