Idea: Wouldn’t be cool for many McLighting (RGB LED lighting using NeoPixels) to talk to each other and synchronize? Implementation: Here is my naive attempt at this, which requires McLighting to be served as stand-alone web-client. Link: https://github.com/toblum/McLighting/tree/experimental/Arduino/MeshyMcLighting Features Uses painlessMesh to create mesh network and broadcasts state to every node Does not need WiFi connection

Idea: Get LIVE stock price on ESP8266 Implementation: Develop a simple Arduino library that retrieves live stock prices from RobinHood in JSON format and processes it for ESP8266. In one example, we demonstrate a whole bunch of stock prices scrolling through a dot-matrix display. Arduino Library: https://github.com/debsahu/RobinhoodAPI

Here is a naive attempt at predicting a particular stock’s price and displaying it on a ESP8266. This algorithm is not the best one out there, but what is being shown here is the ability to port it elsewhere and easily integrate these complex models with micro-controllers (ESP8266) and other devices.

Idea: Control components on Home Assistant directly from ESP8266. Implementation: Develop an Arduino Library that can be used in various projects without the requirement of setup of a MQTT sensor + automation on HA. This uses RESTful API commands (link). Arduino HARestAPI Library: https://github.com/debsahu/HARestAPI

Idea: Did you ever want to use ESP8266 to communicate to Home Assistant directly? Implementation: Here we use a color sensor to read colors and change a RGB light in Home Assistant to the color observed. Arduino Code: Link RGB Lights connected to Home Assistant McLighting: https://github.com/toblum/McLighting

Watch liquid Helium boil off to gaseous state from a decommissioned 360 MHz NMR magnet. For every litre of liquid Helium, 750 litres of gaseous Helium is generated. When the Helium boils off the superconductor is no longer a superconductor and this seizes to be a magnet. Watch the steel screwdriver fall off once this

[metaslider id=748] It was a great opportunity provided by Penn State Postoc Society, that both me and Sasmita were able to present a few projects at ExplorationU @ Mount Nittany Middle School. We presented 3 projects that involved light sensors doing some amazing things, particularly a color sensor detecting colors, a gesture detector sensing hand
