IKEA GRONO led-strip upgrade

thingiverse

This is a custom lid for the decorative and low-cost IKEA lamp. I have a working version, but it's not perfect. You can print and build it, and you'll be proud of it, but if you're a maximalist, you probably want to work on it some more. If you want to improve it, please submit a pull request on GitHub rather than just remixing it here! Things needed to build my version: - Wemos D1 mini (you can get one from Banggood or AliExpress for $1.5-$3) - I prefer the slimmer version in general, but this build works with the bigger chip, and the PCB has the same size. - LED strip: I bought a WS2812BECO 1-meter strip with 144 LEDs per meter for around $10 (but you'll only use half of it). - The lid printed - An IKEA Grönö lamp from IKEA for around $10 - A 5cm UTP cable (or at least three small cables) - Basic soldering supplies - Some small zip ties - A long USB cable - A USB charger or wall adapter (you can get one from China for $5) The total cost for one lamp is around $25. Problems with the current design that I discovered when I assembled it: - The space for the MCU is a bit small, could be bigger but it slides well if you do it at a small angle - The wall that holds the MCU could be longer so it would hold better when the LEDs try to rotate it - The pole isn't really comfortable for the 144l/m strip, so you probably need to use zip ties at the bottom and top instead of the glue thingy (I didn't try to glue it, it had too much tension...) - Because of the too small R on the pole, some LEDs could be damaged in the process, they can be manually resoldered if you find out which LED and which leg is the problematic one - The blue LED on the Wemos is leaking through even if I tried to cover it (probably the slimmer version or a flipped PCB could fix this easily) - If your USB cable is old or too rigid, it will open up like mine What I like: - It fits perfectly - Looks decent - The pole fits the bottom hole, so the whole thing is really solid - It seems to be a small modification or even like a bought product
