>>7yep, that's one part of it! SIGINT stuff (wifi, bluetooth, radio, etc) really interests me, it'd be cool to have a rolling signal sniffing platform, or to have my bike act as a piratebox or personal access point.
I've seen people convert water bottles into storage containers for inner tubes and small tools, certainly I can shove a few linux based SoCs in there. the dream would be to have an aforementioned raspi zero w in the bike frame itself, but short of doing major unwanted fab work it'd probably be too difficult.
