This is a list of small hardware projects we have done.
For bigger projects look at:

Energenie sockets are great for building a smart home. These cheap devices that allows you can turn on/off power sockets with a simple remote, a Raspberry PI or even an Arduino/ESP8266 and a cheap radio module.
Smart staircase lights
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.
Featured on Instructables !!
We hooked up a light-dependent resistor to an Arduino and rubber-banded a servo to press the X button for us on the lightning-dodge minigame on Final Fantasy X for PSVita.
Light sensor is an Arduino project with a radio module that sends a message everytime a circuit is closed, or a button is pressed.
We use it to monitor if we left the light at the bathroom on and we’re not at home.
Door sensor is an Arduino project with a radio module that sends a message with light levels at the room.
We use it to monitor if the main door at home is open.
Meteorological station and automatic watering with Raspberry PI
Meteorological station built with a Raspberry PI, a bunch of sensors and a water pump for automatic watering.
If the soil humidity gets below a specific value, the water pump will provide some water to the plants.
Simple automatic watering system with Arduino
Simple automatic watering system with Arduino, a water pump and a sensor.
Switch between by frequency or humidity functions.
Turret-pi is an attempt of building a Portal turret using a Raspberry PI, a IR presence module, a vibrator and a portable speaker.
Everytime the turrent detects a presence, it will speak, shoot and vibrate like in the original game.
The implementation in Python was finished, but the final project was paused waiting for a proper casing.
Simplest wireless powered project
Running an arduino sketch (blink) without any batteries using wireless charging.
Arduino and android bluetooth demo
Simple comunication between Arduino and Android using Bluetooth. It will feature an Arduino attached to a motor, that will be listening for speed values over a Bluetooth channel. Depending on the speed value received, our Aduino program will vary the the rotation speed of the motor accordingly.
On the other side of the Bluetooth channel, sending the speed values, will be an Android app, that will feature a graphic interface with a slide to select the desired values.
