I'm not too sure where to download the new .jar file to get it to a more recent version.
So technically it will work. The big question then becomes is it useful? Low power but needs a screen. Can we leverage it in anyway?
I'm thinking if it gets into schools it might be useful but if it needs a more powerful machine than the school might purchase can we nudge up the specs in someway? I know you can use a smartphone but JOSM is a bit more powerful and you can grab a bit of osm compress it then load it up on the pi. Not real time but in areas where there is little activity a 3 or 4 day old file might well be good enough.
I'm thinking Africa here. Solar panel into a powerbank, run the pi from a powerbank. On a slightly larger scale solar panel into an instant pot with battery, gives you enough power to run a pi as well.
Instant pots have been run from solar with battery, the 3 quart pot requires a lower power level.
Can someone come up with a mixture that would work?
Thanks
