A couple of years ago, I bought two of these fox deterrents for my front lawn but they stopped working during the winter. I’d assumed that there just wasn’t enough sun to keep the internal batteries charged but, when I took a closer look this week, I discovered they both have a manufacturing fault. The […]
A friend recently sent me a link to this little gem of a transceiver on eBay. Although it’s been around for quite some time, it was new to me and, for the amazingly low price of £19, it was too good to miss. When you consider that the established manufacturers of amateur radio equipment would […]
Probably my last project until the darker nights are upon us again. Full details on my website: XR-2206 5Hz to 300kHz Function Generator
In July last year, I posted about a dashcam I’d fitted to the car.. well, the GPS unit packed up last week. Also, the connections on the mounting bracket (which were always a bit suspect) had got worse so I decided it was time for a new dashcam. Unfortunately, of necessity, these cameras operate in […]

By the time I’ve worked through the menu system and remembered which button does what, I’ve lost interest! Of course the smart phone […]
There are many devices which are designed to plug into a car’s auxiliary socket (formerly known as the cigarette lighter socket) which, ideally, depend upon the voltage turning off with the ignition. One such device, which I’ve recently fitted to my own car, is a dashcam. Luckily, the power to my car’s auxiliary socket is […]
Finally written up the details of my rechargeable lithium battery tester and put the info on my main site for anyone interested. vwlowen.co.uk/arduino/battery-tester/battery-tester.htm
With one thing and another, my rechargeable battery tester project has taken a bit of a back seat since the parts arrived two weeks ago. I needed to spend some time tidying the garden now that the plants are starting to die back and then the computer decided not to behave. Everything tested out ok, […]
