Introduction: Some projects nag at you for years. This is one of them. About three years ago I transplanted an ESP32 into the cheap-and-cheerful dehumidifier that keeps our conservatory habitable, wired a relay across its ON/OFF button, and called it “smart”. The trouble was it could press the button but it never really knew whether […]
Introduction: For those unaware of the event, CeBIT is held annually on the Hanover fairground. For an idea of scale, the exhibition area roughly covers 450.000m2 and the five day event attracted over 300.000 visitors this year. For those of you who know the IP EXPO in London, imagine 15+ halls like it and multiply

1. Introduction: Since I’ve just upgraded the NAS I’ve ended up with a spare Mini-ITX Atom board. Perfect timing to replace the old Smoothwall gateway and finally eradicate the last 32bit machine I’ve got running 🙂 I’ve been using Smoothwall since 2007 now, my first box was based on a P3 1Ghz but quickly replaced

Introduction: This is the first of a series of posts to describe my second Arduino automated greenhouse. It’s simply too big a project to cover everything in one post so I’ve decided to split it into a few smaller posts. In this first part I’m going to quickly describe my water, power and network setup.

1. Introduction: I made a water level sensor a little while a go to measure the water level in my underground rainwater harvesting tank. Thanks to the Jubilee I found time to finally setup the first part of my Arduino/Xbee wireless sensor network and the first sensor node was also meant to read from this
1. Introduction I developed this WSN for a coursework on my MSc and I’m hoping others will find this useful or at least interesting 🙂 I’ve just installed the first parts of this WSN back home to collect sensor data from various outbuildings and it will be part of my new Arduino controlled greenhouse project.
1. Introduction: I went on free sample spree a little while ago and then got myself a few “younametheDIYunfriendlypackage”-to-DIP adapters off ebay (more details on the adapters are in one of my previous posts (DIP adapters to convert less DIY friendly packages (SOP, SOIC, TSSOP, MSOP, SSOP, SOT, LCC, LGA)). This is the first little
Introduction: The friendly postman left me a “you weren’t home” card yesterday so I got curious since I didn’t expect any deliveries. Farnell had given me a delivery slot for next week (28/05/2012 onwards) but a quick look into my profile confirmed that they had already sent it 🙂 Followed by the usual 24hr wait

Introduction: Since a couple of manufacturers have kindly agreed to provide me with free samples of their ICs I’ve obviously had to look for adapters to convert the rather DIY unfriendly packages to a more Arduino friendly footprint so I can use them for my prototypes. I’ll continue to share further results as I go
