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 is not perfect. You can print + build it, and you can be proud to it, but if you a maximalist you probably want to work on it a bit. If you want to improve it, pls give a [PR on github](https://github.com/tg44/3d-tools-and-things/tree/master/ikea-grono-lid) rather than just remix it here! Things needed to build my version: - Wemos D1 mini (banggood or ali-express will help you out) 1.5$-3$ (I prefer the slimmer version in general, but this build with the bigger chip, the PCB has the same size) - LED strip, I bought WS2812BECO 1 meter, 144Led/meter ~10$ (but you will use only the half of it) - the lid printed - An Ikea Grönö lamp from ikea ~10$ - 5cm utp cable (or at least 3 small cables) - basic soldering supplys - probably some small zipties - a long usb cable - usb charger / wall adapter (5$ from china) Total cost for one lamp ~25$ Problems with the current design that I discovered when I assembled it: - The space for the MCU is kinda small, could be bigger but it slides well if you do it in 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 is not really comfortable for the 144l/m strip, so you probably need to use zipties at the bottom and the top instead of the glue thingy (I didn't try to glue it, it had too much tension...) - Bcs of the too small R on the pole, some led could be damaged in the process, they can be manually resoldered if you find out which led, and which leg is the problematic one :D - 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 - 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
