This is a short summary of what I learned while playing around with my Bangle.js Watch.

I managed to

• add an application to the Bangle.js (with create-bangle-app)
• send accelerometer data over Bluetoot Low Energy
• discover & connect to BLE devices with Node.js
• read accelerometer data with Node.js (coming from the watch)

Recently I got myself a treat: a Bangle.js Watch! ⌚️

It's a pretty awesome, open-source watch based on Espruino and Node.js, and much more! 🤓

Read about my experiments here especially for creating a mouse-watch app with Node.js and Bluetooth Low Energy!

Using an ESP8266 for IoT projects makes me go fast while prototyping.

The compact format is perfect for small DIY devices.

Wi-Fi connectivity is built-in, and it's super affordable.

The ESP8266 is a low-cost Wi-Fi microchip, with a full TCP/IP stack and microcontroller capability (wikipedia)

Time-lapses always fascinated me. So I wanted to create one on my own.

Had a spare Raspberry Pi Zero W catching dust, you can purchase one for ~ 25$ and the related Raspberry Pi Camera module for < 20$.

home-assistant.io is the latest great tool I discovered, it's simply a beautiful piece of technology.

Open source home automation that puts local control and privacy first

I recommend installing the Hass OS on a Raspberry Pi 4 with an SD Card of at least 32GB.
