This spring before launching swimming pool I decided to build an automated sun water heater which should heat the water during the sunny days.Continue reading “Sun Heater for Swimming Pool”
The goal of this project is to add an ability to remotely control Webasto heater in my vehicle.
Just completed soldering stable version of weather station based on ESP8266, it measures temperature and humidity using DHT22 sensor and also luminosity.
Current post describes implementation of OwnTracks geo data and then draw they on Google Maps.
Below you can see my main circuit which I use in my projects. Based on my experience I’d suggest that this is most of the stablest version.

Recently I built the second revision of my pulse counter to measure power consumption in my house.
The version is using plastic box and installed to DIN rail, it also has interface to re-programm ESP chip and reset button.
Recently I decided upgrade my car entertainment system and make my car more smarter. I’m as usual car owner have manufacturer in-dash car system with LCD screen from VAG, but I do not use anything such as Navi, TV, radio, only line-in 3.5 jack and I’m playing my online streams from cellphone, nothing else. So, the plan of this project is to have system with next functionality:
- play online streams, my favorites are DI.FM, Soundcloud
- navigation, Google Maps for example
- manage car functionality, like door opening and auto-start engine remotely
- capture car debugging information through car data bus OBD2 protocol
- share Internet through Wi-Fi and able send/receive audio through bluetooth
I started my discovering from Raspberry PI as a hardware platform which I used in my other projects and tried to find proper software solution for Raspberry PI. I’ve found that recently Google presented platform Android Things to develop own projects for IoT devices. I took my brand new PI3 and flashed Android Things Beta image, then using ADB interface connected to device and installed Android Auto software. Unfortunately Android Auto didn’t start to work due incompatibility of versions of Google Play Services, I’ve tried manually update software but stuck due a lot of restrictions and incompatibilities in versions. Based on first negative experience I’d say that current platform is so “rare” and unfortunately I won’t use PI3 with Android.
After all I ordered Odroid C2 which has support of native Android out from the box and looks like solution is much stable.
Some time ago I decided to buy a 4K camcorder to capture some amazing videos across the world and then enjoining the same picture on my TV sitting at home. The idea was to have a window into places which I love.
After some playing with different types of the switches which controlled lights through my Home Automation System I figured out best implementation of smart switch and in this post I will show you what I made.
In this post I want to share my knowledge about device which now controls my air conditioner and allows me remotely through my home automation system control temperature.
