Another Pi Zero W, a Zero 4U USB Hub and Unicorn pHAT.
I've got fed up unmounting the Fly6 and Garmin Virb cameras from the bicycle, so that I can plug them into the NAS to charge the batteries and dump the video.
I can mount this stack of cards next to the bike, plugged into the same mains supply as I use to charge the Exposure lights. With a little bit of bash scripting, it should be able to recognise that the devices have been plugged in, and start a transfer over the network to the NAS. The Unicorn PHAT will allow me to display some basic status information about the devices plugged in, the networking connection, disc capacity etc.
It's always amusing that almost every extra board you buy for a Raspberry Pi Zero W, costs more than the processor board itself !
