RGB USB Nightlight

This is a neat project that turned out to be a real nice nightlight! It lasts about 2 days off a 2200mAh USB powerbank. It is based on a Geekcreit® DIY C51 RGB Colorful Crystal LED kit that I got from Banggood (sadly no longer stocked there, but should be available elsewhere). Basically it is a MCU controlled, 10 RGB LED display. It has a number of different "modes" that are selected by briefly interrupting the power, and it has a light sensor (LDR) which will adjust the speed of whatever mode is currently playing (more light on the sensor = faster speed) Here's a 2min video of the different modes (yes, I know that I messed up the layering of the frosted film, it's on the "To-Do" list) - https://www.youtube.com/watch?v=3wFMxJKNYyA I designed this case in Fusion360 (Fusion file included), it is split into 2 halves as it wouldn't fit on my printer in one piece. There's also a couple of strengthening bars to reinforce the join (only one is in the files, but you need 2 of them for better re-inforcement) I just used hot-melt glue to stick the pieces together, but superglue would also work. Then to make a front cover for it I used some clear acetate ( Cake collar, Link for the clear acetate :- https://www.amazon.co.uk/gp/product/B07R5P55JF ) and then applied 2 layers of self-adhesive frosting film ( Link for the diffusion film :- https://www.mdpsupplies.co.uk/glass-lightbox-films/etched ( I used Ritrama - Easy Apply Regular Etched ) ). I have a craft vinyl cutter (Cameo4) and made up a cutting file for the frosted film (Attached SVG file) which has 2 pieces, 1 for the inner face of the acetate (allowing you to cut the clear film oversize, and then stick the "inner" frosted film on and then trim the clear film to the same size as the inner frosted film) and the 2nd larger piece which, because it is bigger than the inner piece, will allow the adhesive to stick the whole frosted diffuser to the 3d printed case. That sounds way more complicated than it actually is, I made a video about assembling the whole case - https://youtu.be/_0_PeFzIbWM I also made a video covering the actual building of the kit - https://www.youtube.com/watch?v=nnGKj40KpCE
