Combining that with my passion of microcontrollers and LEDs ( see similar ) and taking inspiration from others before me (this) , here's what I ended up with. Update…

ESP8266 Window Sensor with OTA and Deep Sleep

I was looking to boost my home security by adding window sensors. Something small and obscure so it would not stand out. I landed on this axGear sensor unit. It is small (70 mm x 20 mm). However, there was only one problem - it comes with proprietary software that I'm not sure I can trust. I also intended to integrate it with the ecosystem of devices I've created which I manage using Blynk. Of…

Tag along on my journey electrifying this Triad Drift Trike with an e-bike motor and battery pack. You'll also get to hear about my experience as a first time noob MIG welding.

Review: Newwear Q3 Smartwatch

I was recently sent this Newwear OLED Smartwatch from Banggood to try out. It has a number of features including heart rate, sleep, step counter, sedentary reminder etc. Checkout the video below for my thoughts on the watch. The Good: Nice quality screen, heart rate seems accurate, great battery life (note that screen turns off after preset time). The Meh: Can barely read the screen in the sun; forced to navigate through all items one-by-one.…

It's…
