Heating Control

For my ongoing heating project I needed to be able to communicate with different nodes around the house. Wirelessly. To accomplish this objective, I decided to use some NRF24LO1+ modules. These are great because they have an onboard chip so that you don't have to encode/decode the data yourself. The range on them is pretty good - 'proper' testing this w/e! - I got two without antennae and one with one - this is going to be the hub on a RPi so the range needed to be further (apparently someone got the to work over a distance of 1km!). First, the Raspberry Pi side. I hooked up the RF module and wrote this script: https://github.com/ continue...

ReCoRVVA - a Pi powered hamster hunter!

I know I haven't written anything for a while, but I have been doing stuff! My latest project was one I have been doing with Ben James (the hamster owner) and Angus Ledesma. It was a British Science Association CREST project and our idea was to build a shoe-box sized remotely controlled robot vehicle equipped with a range of sensors such as temperature, humidity, distance and a camera. The vehicle was built from a tracked chassis kit, two motors (to drive the tracks), two servos (to pan and tilt the camera), a Raspberry Pi to control everything and a LOT of batteries! The vehicle could be controlled from anywhere in the world through a web-based user interface to the controller continue...
