Arduino ESP8266 Smart Motion Sensor using PIR and MQTT


My son has a cat. And I've become very curious about the cat's feeding and toilet habits. Mainly I'm interested in how long does it take him to go to the toilet after eating as I've noticed a pattern: At first he goes to the kitchen, eats and then runs around the house wrecking havoc for some time and then goes to the toilet. So I'm curious whether this is his usual routine and moreover how many times during the day and night does he need to use his toilet. I might even build a collar for him to track the magnitude of his movements in the future :)

Arduino Developing with Atom IDE and PlatformIO for AVR and ESP chips

There are many different ways to develop and deploy embedded solutions, one of the most popular ones would be Arduino IDE. But the editor is very simplistic, without handy features such as intellisense, code refactoring and many others. I've used AVR Studio, IAR, even VIM to develop code for AVR/STM microcontrollers.. But they are either designed specifically for that platform or are commercial products. And I love Open Source :)

Building ESP-1 Balancing Robot

I was always fascinated with balancing robots and wanted to build one myself. Some time ago I started collecting IMU, arduino boards, wheels, motors for other wheeled robots and one day decided to build a balancing robot instead. I've used wheels from old four wheel drive robot that used mouse sensors for odometry and was driven by an Arduino Pro mini. That robot never went alive anyway :)
