MateLight-ScrewCap

This Repo is based on the idea of MateLight and improves it by a screw cap which is easy to install and easy to remove from the coasters.

In this Repository you can find

PCB schematics and board layouts created in Eagle,
PCB Gerber data (ready for manufacturing),
a 3D model of the PCB and
a 3D model of the screw cap (for 3D printer).

Have also a look to the following Repos with Python Code for our MateLight for use with a Raspberry Pi:

A small presentation about the PCB assembly process can be found here:

Fork me and have fun!

Power source

An APA102C LED consumes a maximum of 60 mA (red/green/blue each 20 mA). It is recommended to use a new 5 V / 1.4 mA power source for each 20 bottles(higher current delivery does not matter).
