Why make a Light Switch I needed a Wifi connected light switch for the workshop, something a bit more robust than the usual indoor white plastic type. It had to run Tasmota – none of that Tuya stuff. So I built one based on some metal push buttons, supposedly waterproof, […]
A small background project. I first looked at this for RC planes. Arduino compatible ATMega328 based module with on-board micro-SD socket. At the moment mostly just a working board in need of an improved sketch to make it more useful. Should be useful for some other SD logging applications. Features: […]
Update – March 2023 The Orange Pi EMMc flash died, probably because I was writing data to InfluxDB every 30-60 seconds for 3 years without compacting it at all. I suspected this would happen but didn’t get around to doing something about it before it failed. I’ve looked at the […]
The old analog cctv system have been updated to IP cameras and a dedicated NVR rather than a general PC and Zoneminder software. The mini-DVR has been modified to run on the 24V solar-battery system. Some more information Here.
Manual shipping of small packages through a NZ Post Shop has become significantly more costly with increasing prices and the introduction of a much more complex and time consuming customs form. For smaller Air-Post packages, until recently we would print the address label, attach it to the package and complete […]
NiMh Cells Seem To Be Fading Away We have used NiMh cells for years, but they are now harder to find and a lot more expensive. So we are switching the main batteries from 8-cell NiMh to 3-cell 18650 cells with a BMS. We still need a stable and safer […]
The problem: As of WordPress V5.0 they have inflicted the block editor onto us. I suspect this is a very bad attempt at a sort of year-1 finger-painting for web page creation. It may suit one page school projects quite well for anyone who has grown up with cellphones and […]
Wanting an OSD to display the basics and GPS information in a small FPV plane but not wanting to waste a lot of time playing flight controllers, I decided to try the MinimOSD Micro running with just a GPS module and a small current sensor. I don’t run Windows so […]
