Hi,
this is awesome. I also started to think about something similar myself
- just a device to be able to let people write their USB device with. My
main criteria for a system that can be used by visitors was that it
supports USB3 to make flashing at as fast as possible. I found the
ODROID-XU4 which is super expensive but has two USB3 ports. However
last time I checked it required a binary blog from ODROID to operate
and I heard that the fan might be a bit loud. However other problems
with Fedora events prevented me from finishing build this and eventually
I just a bought a new notebook with USB3 that I use on events to flash
the visitors' USB devices. A cheap chromebook with USB3 might therefore
be a good alternative as well.
Kind regards
Till
