IKEA Motion Lamp Hack Update

Back at it again, I decided to add a few more features before I deem this project complete and ready to be put into service. In case your are wondering, this is based on my previous work on the IKEA Motion LED Lamp Hack. This time around I just wanted to make a few hardware changes that will let me have full control of the light.

IKEA Motion Lamp Resistor Modification

IKEA Motion Lamp Hack

Last year while visiting a friend for the Portland Mini Maker Fair I became the owner of an IKEA STÖTTA, a battery powered, motion activated, LED lamp. I knew it was ripe for hacking. After arriving home, it sat on my desk waiting to be disassembled to reveal its secrets. I figured the only way to get it off my desk was to get around to tearing it apart and seeing what I could do with it. Over the weekend I spent more time trying to decide which direction to take since there are plenty of features I could add. At least I can get something going now and add to it later. Who ever said a project had to be completed?

IKEA LED Light PCB Close Up

The lamp consists of a small PCB which contains the following main parts;

• HS8A005 (BISS0001 Motion Detection IC)
• PIR Sensor
• LED Driver (Inductor and IC, powered by battery VCC and outputs 3V)
• 3.3V Regulator
• Voltage Detector (Disables trigger on low battery)

La Crosse Weather Station Gateway

Its alive! Last Christmas (or was it the one before that?), I received a La Crosse wireless weather station from my mom who is obsessed with them. This one has just a small display that can gauge inside and outside temperature. What interested me is that it's a simple 433Mhz radio link. So sometime between then and a while ago, I got a 433Mhz receiver from Sparkfun with the intention of capturing the binary data from the outside sensor.
