Ever since I put a mailbox out on my front gate, I have to check it manually to see if the postman has delivered any mail. That involves getting out of my car on the way in or out, or (ugh) walking all the way out to the post box! So, I’ve now installed a Raspberry Pi by the post box to send a text whenever something is put in the post box!Continue reading “Mail-Pi – Raspberry Pi Post Box SMS Notifier”
Over a year ago I did an article about a DIY alarm system I’d build based on Raspberry Pi’s. I’ve recently done an update, and this time I’ve cleaned up the code and released it onto GitHub. It’s based on Node-Red and Python.Continue reading “AlarmPi – Raspberry Pi Security Alarm Pt.2”
I decided a few months ago to cut the cord and get rid of my Sky TV subscription. Between a combination of purchasing and returning a Saorview Connect box, and trying out various front ends, here’s the end-result, and I’m delighted with it.

A few months back I built a full LoRaWAN gateway node for The Things network, and now I’m finally getting around to writing it up. I’d recommend this project to anyone interested in IOT, as it’s very edudational, and you’ll be helping expand the LoRaWAN network coverage in your area. In this build, I use a Raspberry Pi, a RAK831 8-channel gateway and an adapter board (also from RAK) that allows the RAK board to be mounted easily on the Pi.
Over the last while I’ve been having a problem with excess humidity in the shower rooms. Imagine that, the builder never put in extractor fans when the house was built! Anyway, I could put in those fancy extractor fans with the built in timers or humidity sensors, but I decided to do things the more interesting way, by using a small computer to read the values from a humidity sensor in each room, and based on the readings, turn on the fan until the humidity was reduced to an acceptable level.
I got myself a new Raspberry Pi 2 Model B this morning. I was intrigued by its quad-core cpu and how it would stack up against the other single board computers that I’ve benchmarked in the past, which were:
- Raspberry Pi Model B+
- Beaglebone Black
- Intel Edison
- Imagination MIPS Creator CI20
The Raspberry Pi foundation announced it’s latest member of the Raspberry Pi family, the Model A+. This is a departure from the usual credit card form factor, in that they’ve managed to knock off 20mm from the length, resulting in a very nice 65x56mm form factor.
Recently I took delivery of an Intel Edison with a Mini-Breakout Board. I was awestruck by the size of the thing, but it was not until I started using it properly for a couple of projects that I noticed that it seemed a little bit ‘snappier’ than boards I’d used in the past (Raspberry Pi, Beaglebone Black). So I decided to do a little benchmarking.
