I’ve kicked the tires on using Arduinos and RPis to “enhance” my SOTA experience but in general felt the hassle factor really didn’t justify it.
I thought it would be ”cool” to use an Arduino to collect UV levels, ambient temperature and barometric pressure on the ascent (the Western US can be quite human hostile). Prototyped something and “dogs dinner” is a generous term to describe the end result.
Then onto the RPi. I acquired the 7” RPi foundation touchscreen and mated it to a nice body with the intent of running FT8. WsJt-x required a larger screen resolution and so usability killed that project. Which wasn’t all bad as my mountaintop FT8 activations using a windows tablet showed me that muscle counts.
I did get Fldigi running on my RPi 7” but PSK 31 seemed to hit or miss for SOTA.
I even acquired the smallest keyboard known to man to help reduce weight…
