Please refer my March 2025 diary entry as this is changes only.

• Changed the voice recording notes method to a dedicated microphone nearer my face. I launch a script at the same time I start the side cameras. It still saves as date/time stamped 1 minute length files.

• Use a dedicated 2nd WiFi device on the laptop for direct connection (not using in van WAP) to the 225deg side facing camera. This increases the max framerate slightly. The 270deg side camera is still USB connected.

• Procured a cheap 2K dashcam and mounted it rear window. Actually has a GPS position reporting fault, but the clock is okay. Do a lot of local processing to geotag against the UBLOX GPS unit to give 1FPS above 45kph and 3FPS below. Very handy for capturing the back side of speed signs by either swapping views locally or seeing the signs recognised on Mapillary.

• The WiFi/cell router now has two antennas connected (MIMO) which helps the upload rate rate and low signal area performance. Now upload 15-40GBytes for each drive day.

• One of the 20 year old Toshiba laptops had a temp sensor fail such that the cooling fans wouldn’t start. Upgraded both to 10 year old HP Probooks. These reduce processing time approx in half. The extra dashcam included. Still running Debian Linux.

• No longer beacon APRS.

• GPS nav unit now has giveway and stop sign POI’d displayed, so I can add these to the voice notes. I continue to create other special POI’s plus modify the mkgmap process for better end use.

Currently near Injune Qld about to sit still for a while.
