The Power Progress Community non profit association is trying to fund a new notebook based on a NXP T208x processor. This organization is accepting donations with the objective of collecting funds to establish a contract with Acube Systems to design the laptop's motherboard. The campaign started last Friday reached a 10% of its goal in 24h.

The objective is not only to build a notebook but to promote the use of Power technologies for home computing as well. We want to create an open computer and certify it as Open Source Hardware if possible. We are commited to distribute all the work performed in the scope of the project as open source, publishing documentation, designs etc.

The circuit in a breadboard

This is a quick example of how to use websockets in an ESP8266 device. I wanted to experiment with websockets and this was a simple way to do it. The device runs the websocket server and its code is very similar to what you can find in this example. On the other side, the client is a Qt (QML) application. I think QML is an easy way of developing applications and the advantage is that you can use the same code in a smartphone or a desktop PC. If you prefer, before reading this article you can find the source code repository here.

Requirements

  • This source uses Arduino IDE and its standard libraries
  • Additional libraries: arduinoWebsocket
  • QT creator IDE for the client application

Fritzing schematics

MeteoHome is yet another weather station project using a NodeMCU ESP8266 devboard with DHT22 and BMPP180 sensors. The particularity in this case is the configuration using a captive web portal and the use of MQTT to send the information to a server. Additionally the machine that gathers all the data runs Home Assistant which is the responsible of showing the current status of the sensors and historical graphs. You cab grab the source code of this project here.

 Features

  • configuration of WiFi network and MQTT through a web portal
  • Deep sleep mode included for being powered by battery
  • Temperature, humidity and air pressure measurements
  • Possibility of being used with Home Assistant

Coque is a QML minigame for my little son

I'm just starting a minigame for my little son. He is only 19 months old, but enjoys playing with a tablet and loves cars.

This screenshot shows the the current status of the application.

 The app will be very simple: there is not collision detection, only some items to touch and make some sounds. I'm using QML for this and seems very easy to develop all the things I have in mind.

If I have time, the game will be available for Android for free soon.
