Communicating with Bangle.js Watch over BLE with Node.js
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)
Bangle watch as an accelerometer mouse
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!
DIY IoT door monitor with ESP8266
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)
Simple Time-lapse with a Raspberry Pi
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$.
Install Homeassistant on Raspberry Pi
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.
