Make your own weather station with some sensors and a Raspberry Pi
Jeremy Morgan has recently been tinkering with a bunch of sensors attached to a Raspberry Pi, out of which he has made a ‘weather station‘. The station measures temperature (several different ways!), humidity, barometric (atmospheric) pressure and light levels/luminosity (lux). He…
#PiWars proximity alert challenge inspires blog post
Brian Corteil is one of this year’s Pi Wars competitors. One of the more interesting challenges he, and the other teams, face is “Proximity Alert”. This challenge involves approaching a wall and stopping as close as possible to it without…
Programming autonomy with the Raspberry Pi and the GoPiGo
Dexter Industries’ GoPiGo is a great robotics kit for the Pi. They’ve done several tutorials based on the kit, but this one caught my eye. This code teaches the robot how to be ‘autonomous’ to a certain extent. It allows the robot…
Artificial pancreas for diabetics run by a Raspberry Pi
This blew me away when I read it. Seattle-based Dana Lewis suffers from Type 1 Diabetes, and has done since she was 14. One of the issues facing diabetics is that during the night, despite having all kinds of different…
Bathroom moisture extraction controlled by a Raspberry Pi
Dave Hunt’s bathroom didn’t have extractor fans fitted when the house was originally built. He decided to overkill the problem by having a Raspberry Pi control some new fans he fitted. He uses AM2302 humidity sensors to detect the moisture…
SenseHAT launched by the @Raspberry_Pi Foundation – an extensive first look
This morning, the Raspberry Pi Foundation announced the immediate availability of the SenseHAT. The SenseHAT is the guts of the Astro Pi and has an inherent space-aged coolness built in. The board you hold in your hands is the same hardware that is…
Basement storage temperature and humidity monitor with a Raspberry Pi
A basement full of old books but no way to monitor humidity and temperature. Enter a Raspberry Pi. This hacker has put together a DHT22 sensor and an LCD screen with the Pi in order to monitor environmental conditions in…
Oxford Flood Network uses Raspberry Pis to detect rising water
The Oxford Flood Network uses a network of ultrasonic sensors in a flood-prone area to detect water levels and broadcast their data over short distances to Raspberry Pi-based gateways; these aggregate the data and pass it to an open online…
Create a Raspberry Pi iBeacon and iPhone app
Shea Silverman has blogged about creating a bluetooth iBeacon by using a Bluetooth dongle with a Raspberry Pi. He’s written comprehensive, though brief, instructions for setting up the iBeacon and then gone on to explain how to alter the downloadable software to…
