Smart Staircase LED Lighting With Arduino and IR Sensors

| Comments

For a long time, we’ve been turning on the lights at the beginning the staircase, just to turn them off when we reach another floor.

But instead, we built a simple system to turn them ON automatically when you are going upstairs or downstairs, just by using a couple of IR proximity sensors, a relay and an Arduino Pro Mini, to control the timing.

RPS: A Simple RTS

| Comments

If you follow me or Coconauts on Twitter, you might have seen some GIFs about an RTS game we’re developing on

Codename: RPS (Rock, Paper, Scissors). Is a simple RTS (Real Strategy Game) we’re building using the framework for HTML5 games.

We aim to have a fun and complete game, with campaign, multiplayer and with a fresh interface, compatible with mobile and touch devices.

The main selling point are its simple but effective mechanics. Forget about hundreds of different units with their own powerups, multiple buildings, or advanced research.

Control Energenie With Pebble

| Comments

Last year I got a cheap Pebble smartwatch just days before the company was sold to Fitbit

One of the reasons was to play with it building our custom apps, so we built an app to control our Energenie sockets from the watch, sending HTTP requests to a Raspberry PI with the official radio module from Energenie.

All you need, apart form the pebble is a Raspberry PI to send the radio signal from a REST API to a Energenie socket. Check how to do it on our previous post.

You can see it in action here.

Con ustedes, ¡el episodio piloto del podcast de Coconauts!

Ultimamente, dado que vamos al trabajo en un trayecto largo en tren, nos hemos enganchado a escuchar podcasts (mayormente de videojuegos). Sin embargo, no hemos encontrado ningun podcast de tecnologia o desarrollo en español que nos guste, así que nos hemos planteado ¿por qué no intentar llenar el hueco?
