Introduction: I’m harvesting rainwater from a couple of outbuildings via 110mm underground pipes connected to an underground storage tank. Since I want to stay on top of the water level in the tank and also had a SRF05 ultrasonic rangefinder sitting in a box I thought I’d put it to good use and measure the […]

Introduction: I’m currently working on a bit of coursework which includes XBee shields and XBee 2.5 ZNet modules. Since I want one of my nodes to form a bridge between the XBee network and my existing ethernet network I bought an Arduino Uno and one of the new ethernet shields with micro-SD slot. The pictures

Introduction: Since I’m planning to extend the greenhouse Arduino system before the next wave of plants go in I decided it was time to upgrade myself to an Arduino Mega 2560. All my existing shields appear to work with it but for trying new ideas out in the wild I prefer protoshields over breadboards so

Since our library at work has opened a down stairs sweat shop to put RFID tags into all our quadrizillion books I obviously came up with the idea to play around with said tags. They are from 3M and as far as I can tell just basic RFID tags, nothing fancy or tricky. If I

I’ve been working on this for a while now but have finally managed to get hold of all the additional fancy parts I wanted. I have a prototype (excluding the ethernet shield) which reads from all sensors but I need to spend a little bit more time with the code that writes to the csv

I’ve actually just finished this one so I thought it should make a good first project post 🙂 The project: The general idea in my head was to switch 240V circuits both from a webserver and a wall mounted control board. This currently allows control for three circuits. Channel one switches a 240V 4-way extender
