I was away camping for the eclipse so I'm a bit delayed in this response.
Great video
@second exodous. You had several comments around the nub-click and that you couldn't envision it working well. I might be able to explain how it was envisioned.
Much like the Pandora, the left nub is the mouse movement.
If you want to rightmouse click, you simply tap in the LEFT nub wherever you have navigated to. Consider this, "I'm exploring something on the desktop and want more information - I momentarily click the button that I used to get there."
If you want to leftmouse click, double click or click and drag, press, double press or press and hold the RIGHT nub and drag with the left nub.
Now, if you MUST, the above could be configured in mirror to the above. Navigate with the right nub and left click with the left nub, etc...
I had found the 'mushy' keyboard as 'best'. Odd that you liked the much stiffer versions. I see a key press as a collection of critical values. It has to be firm enough to prevent accidental strikes. Anything beyond that is 'wasted energy'.
Your Blender-laptop-pyra considerations gave me some thoughts. Assuming that blender runs on the Pyra - which it
should. The 'long compute' portion is the renders themselves. That part can run unattended. If the device can be powered on all day while you ride - it won't matter so much how long the render actually takes just so long as it is done by the end of the day's ride. It sounds like you'll be staying at places that should have electricity.
In theory, the render could be started on the Pyra then packed away with a power pack type battery and left to run while you ride. There is a catch though - heat. You'll have the Pyra running at 100% CPU in an enclosed space. We need to figure out a way to get the heat from the Pyra -out- of the plastic saddle bags on your bike.
The size/weight of the power cell could rapidly become an issue as well. Biking inevitably involves hills. Any downhill steep enough to require braking could generate electricity with a flip on-off generator. We used to have these for headlights on bikes - they were worthless, inefficient and could lock up a tire on wet leaves. There has to be a modern version that is much more efficient though. If you had something like that you could potentially brake-charge the power bank on the downhills and decouple it for the uphills. The complexity of that system, though, might not be worth it if you have ready access to electricity in the evenings anyway.
The big question in this scenario - how do you reliably get 8W of energy -out- of a thick walled plastic jug/tote on a 40C day from a 65C hot spot (Pyra SoC)?
