New Development PC

My old development machine (bought in 2019) is ready for replacement as it's BSODing more and more, so I'm switching to a shiny new dev system over this weekend and likely some time into next week as I'm building it myself, which is always fun. (not!)Huge thanks to all supporters for making this possible. U...

SSTV Robot 36 Simplified

Mainly for my reference, trying to distil the ridiculously bloated documentation about SSTV into useful and succinct information. I.e. the way it should be anyway.

Please don't ...

nicFW950 PoC Firmware

This is not a functional firmware, it's a proof of concept. Basically it demonstrates I can get my code to flash and run on the RT-950 Pro.You do not need to flash this unless you want to see some blinky lights and/or verify that my code is indeed running.That's all it does, flash the green led, backlight and k...

nicFW880 V5.08.01B [Release]

I do not own Bajeton or other duplicate models so I can't supply images for those, however if anyone would like to email me those images I will add them to the list here.

APRS is Stupidly Complicated

So as I research this, APRS has a whole bunch of different standards. They couldn't just use one and stick to it could they? Oh no! And what's more, the standards themselves have a further bunch of caveats and sub-standards.Coding something to deal with all of this would be a challenging nightmare in a high lev...
