This would be incredible if gotten to work with a pi. I've been eyeing the Jetson Nano, but if I could use a pi with a V100, that would be hilarious. And awesome.
Based on what I've seen - it's on my list of projects to "try out", but rapidly becoming a more obsolete idea the longer I wait (but then again, I've got an Altair on my todo list, so meh)...
Taking a low-cost Mini ITX board and pairing it with a decent mini-sized GTX 750 TI SC video card (I prefer the EVGA one) should yield a system that is somewhat on par with some of NVidia's embedded ML offerings, with the tradeoff of size and efficiency - but at a significantly reduced cost.
Add a very short PCIe riser ribbon (or, if you can find one tall enough, a right-angle riser), and you could lay the card over "flat" above the CPU (using a 1U cooler/heatsink); you'd have to make a custom mounting frame of course, but I think you could make the whole package relatively compact.
From my limited experience using Tensorflow with the 750 - it is a very capable card in that capacity and relatively inexpensive today. If you were willing to spend a bit more, there are mini-sized NVidia GPUs available in more recent models; of course if space is not an issue, then full-length GPUs can be substituted (my "goal" was to build such a system as close to within the footprint of a Mini-ITX board as possible).
As far as the Mini-ITX motherboard is concerned, again, size to your budget. That said, if you decided to build this system using cheap pre-owned components, maybe an I5 with 8 gig - you could probably get it going for under $250.00 USD, maybe less.
Absolutely with a good antenna! It is super super slow as far and transferring text data goes. I can type faster in many cases. At 10W with a good antenna I'm booming the airwaves with my signal! I've made contacts all over the place using Olivia and it's lots of fun. Get a General Amateur radio license (US FCC) and get on the air! There are regular meetings that does this if you want to listen in: http://idigit4u.com/ccara/digitalmodes.html
