Three Way Switching with Tasmota

 

This article will describe one of many different ways that you can create smart 3-way switching for devices like lights or lamps.  This technique can be used to upgrade existing 3-way switches or you can create 3-way switching where it didn't exist before.  This can be done without pulling or installing any new wiring in your walls and without adding or altering any existing circuits.  The 3-way switches can even be on completely different circuits and can easily be expanded to 4-way or even 5-way switching.

Battery Powered LED Matrix T-Shirt

 

This article is a companion piece to the Curtain LED article and video but can also be a standalone project.  Why is it a companion piece?  Well, my intended use is to wear the shirt for special occasions, like Halloween, where the t-shirt will be synced to the LED curtain and both will display the same effect/colors and change from one to another simultaneously.
