This is a wireless controlled interlinking LED tile. Fully 3D printed but also using a NodeMCU and w2812B LED's. I've spent a good few weeks testing, redesigning etc.. but because it's been such an in-depth project, any updates, details, improvements will be on http:// moodlite.co.uk .. This is an open source project, so please if you can lend a hand to improve this project.
The files on here will allow you to replicate what I've done on the video :-) For help / advice etc, please pop by the site above.
The design was done in Autodesk Inventor.
I purchased all of my bits from Amazon UK or eBay, my BOM consists of the following;
60 x LED - W2812B Type. I made sure these were the non-waterproof type as I didn't want them encased in silicon. Cost £12

2 x NodeMCU PCB's. You only need one for the project, but at only £8ish I thought it was worth having a spare. There seem two types, one is bigger than the other one. Make sure you get the one with the square chip and not the rectangle one near the micro usb port. :-)

20 x 50cm Servo Extention leads. Now, you actually need more wire per tile but the 100cm ones were almost double the price. You should get about 15 tiles from about 20 of these. I bought these off eBay. Only problem was they took ages to come.. like 5 days!!

I'm not sure how much filament I've used on this project, maybe a couple of rolls? Anyway, the one I've used again was purchased from Amazon and was Ziro White PLA. I also used this to print the front diffusers. If you use this filament you will end up with the same translucent results I hope. I've found it to be really good value filament, I have it in several colours, but only PLA, not tried other materials yet.

You will need something to power the tiles. I went for a 2A 5V cheap adapter. This powers both the NodeMCU and the LED's. I purchased a 5.5/2.1mm one. I would recommend something like a 4A version which will be good for powering about 20 tiles.

To go with the power supply I purchased some 5.5/2.1mm sockets. I've modelled the power module part on this so if you can get something similar it will save you a job. :-)

It's just a case of having to wait to print off all the tiles then. The base was taking just over 6:30 hrs and the top just over 2hrs. I did a few designs but the one I've ended up with I'm quite pleased with. It allows you to change the tile to a left or a right by swapping the wire underneath. They just slot into each other and you can mount T connectors between them or just screw them to the wall. The front diffuser was originally designed to have a separate diffuser, but I then swapped over to a 3D printed solid one. Both are included in the download so it's up to you which you use.
Any questions.. please ask away
