DIY LED Resin Sticker with Custom Electronics & 3D-Printed Case

Youtube video -----> https://youtu.be/6LOUOs8ukiU

Description:

This project includes files for the LED Resin wearable Sticker. All components, including LED diffusive cases, were specifically designed and manufactured for this project using 3D printing and CNC machining. To control the sticker, I crafted custom electronics, demonstrating in the video how I soldered and assembled everything to achieve an impressive result. The device is battery-powered and charged through USB Type-C. The material used to 3D print the cases is UTR-8100 mate diffuse resin. To control whole thing I used simple 8 bit microcontroller Atmega48. To program the controller via ISP interface, MK2 programmer were used.

Functionality:

Control is done using 1 button. By shortly pressing the button, device wakes up, providing all functions. There are various regimes that can be changed by shortly pressing the button again. If not used, device goes into a deep sleep with almost zero power consumption. Device is designed attached to cloth, so at the other side of it there is a place to solder magnetic clasp (see the video). Overall, according to intentions it has to be used in a dim light conditions at concerts, raves etc. However, it also can be used as a table lamp :)
