leet

Pronounced as "lit". Environmental lighting over gRPC

TODO

Create lighting client, with tempreature setting
Create a color cycle client for when I'm partying alone because I'm lonely
Write an Android app that taps onto new system notifications
Write an IMAP client that polls for new emails
Make the server more generic
- Configuration for service overlay priorities
- Queues for each layer, to enable sharing of layers
Attempt some audio visualisations

WTF?!

At home, I have a strip of 287 WS2812B LEDs connected to a Raspberry Pi, that needs to be used as a light, mood lighting, and for notifications. I don't want to be a typical person and write a monolithic application, so leet is a simple gRPC server that renders basic opacity composition and buffered animations onto the LED strip. This also enables me to add additional sources of data in the future from anywhere on my home network, including servers, phones and your IoT Blockchain AI appliances.
