Small devices that keep an eye on things, made in a workshop in Weldon, Northamptonshire. The first one tells you which plane just went over the house: the Squawk 5 for the desk now, the Squawk 7 for the wall in February. The next two watch an empty cottage and a bird table.
A 5-inch screen that listens to aircraft directly and names each one as it passes: who it is, where it's going, how high, and which way to look. No subscription, works without the internet.
See it working
For holiday lets and second homes. Temperature, leaks, doors, power and noise, with a message to your phone when something's wrong. I'm testing it in my own two places first.
Tell me when it's ready
A camera for the feeder that knows a blue tit from a great tit, and keeps a diary of who came by. Runs on the feeder, no cloud account.
Tell me when it's readyEach one is built on a Raspberry Pi, in a case I print here, and tested on the bench before it goes in the box. If it ever fails out of warranty, any competent repairer can open it and fix it; nothing's glued shut.
The software updates itself over Wi-Fi, so a unit sold today gets the features I add next year. When customers ask for something sensible I usually build it.
Runs are small, so there's sometimes a wait. The product page says when the next batch goes out.
