GPS to micro-SD Logger

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: […]

ESP-8266 Experiments

It’s over a year since I started this in late 2019.  A work in progress, experimenting with the ESP8266 D1 Mini-pro and the ESP-01S running Tasmota.  Connecting to a Orange-Pi attached to the back of a 22″ LCD screen and running InfluxDB and Grafana.  This setup has been collecting data […]

Fix the WP Block Editor

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 […]

Simple FPV OSD

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 […]

Vodafone accidental disconnect – again

What is most annoying is that Vodafone created the fault and we had to wait two days for the repair. If they had said “oops our-bad” and repaired it same day – even if it was overtime – it would have saved me a lot of time, I wouldn’t be […]
