This work extends the IKEA-Hackant project from Robin Reiter, who reverse engineered the controller board of an IKEA Bekant motorized adjustable table.

In my project i connected an ESP-12F module (ESP8266) to the Arduino, which gives us WiFi and quite some processing power to add additional IoT functions to the Bekant table.

An Alexa Skill is implemented, which when activated with a voice command, calls an AWS Lamda function which in turn sends a REST message to the AWS IoT backend....

This is a wake-up light that simulates the sunrise by gradually increasing the brightness of its LED light during a configurable period of time before the alarm time.

These wake-up lights are produced by a number of manufacturers, but here we are building our own with a Raspberry Pi, a handfull of electronic components, the programming language Elixir and Nerves, an Elixir framework for developing software for embedded systems.

This project explores how Elixir/Erlang OTP can be used to develop...

The Raspberry Pi Zero is a perfect board if you want to build small compact embedded systems with the Elixir Nerves framework. The only caveat is, that this board doesn't contain any form of wireless connectivity. But it is quite easy hack a USB WiFy dongle directly onto the Pi Zero.

Elixir Nerves supports the Raspberry Pi 3 WiFi out of the box and also has support for some USB WiFi modules built into its default Raspberry Pi targets. Sadly the driver for the Edimax EW-7811UN stick is currently...
