What are the use-cases for a GPU-accelerated single board computer?
I want to strap it to a drone and fly around with it.

#122This person got hold of a review board and write up an interesting detailed tutorial: https://medium.com/@ageitgey/build-a-face-recognition-system...
That seems like a more interesting article, so I've changed to it from https://hackaday.com/2020/10/05/nvidia-announces-59-jetson-n.... Thanks!

From my experience, 0.05% of the people who have an Ubuntu x.y chose it because of "stability promises" of the LTS release. They just want a quick linux install to run their shit on, or it was handed that way by the Uni department / company / whatever. Or just because it's the biggest name and you're sure to find help online. And then a lot of people don't upgrade - I work with my fair share of people running win 7 (even still have an XP person around), OS X > And knowing that, your idea is to bolt on custom tooling that's not installed anywhere or by no one by default and make it your own infrastructure?
gcc is not part of infrastructure, just like Xcode.app or Visual Studio aren't part of Windows or macOS infrastructure.

Apparently there's a big Software Defined Radio (SDR) community that appreciates the TFlops of floating point compute. cuSignal in particular. Note that embedded radios / modems / codec manipulation is incredibly common. Usually its handled by a DSP (VLIW architecture), but I'd imagine that the GPU architecture has more FLOPs. DSPs probably have less latency, but something like SDR is not very latency sensitive (or m…
It looks like at least one company has started to produce products that tie together the radio FPGA GPU compute pipeline for SDR using cuSignal and these Jetson modules: https://www.crowdsupply.com/deepwave-digital/air-t It's pretty neat stuff to think about DSP on hundreds of MHz of bandwidth being something that you can do in software these days. I remember when that was firmly in the realm of "don't bother unless…
Heck, just being able to find an ADC with hundreds of MHz of bandwidth is kind of a big deal, let alone the computational resources now available to the modern hobbyist.
The modern day has brought incredible advancements to the modern hobbyist. Just 10 years ago, you probably still needed to play with OpAmps and Inductors to effectively read a hundreds-of-MHz signal in any real capacity (at the hobbyist scale at least: $1000 or less projects). A PC probably had the compute girth back then to interpret the data, but you still needed a high-speed, and high-quality, ADC to even read the data that quickly.

#125I have a Jetson nano. It's a nice thing for what it is, and the price. But, the software misses the mark by a lot. It's still based on Ubuntu 18.04. Want python later than 3.6? Not in the box. A lot of python modules need compiling, and the cpu is what you'd expect. Good for what it is, bad for compiling large numbers or packages. They run a fancy modern desktop based on the Ubuntu one. Sure, it's Nvidia, gotta be fl…
Also, no ffmpeg with hardware acceleration. They force you to use gstreamer.

I'm not going to lie, I don't understand the usage of Python and other such languages in the embedded space in general.

gcc is part of the infrastructure, for the simple reason that you need the same compiler version to build Linux kernel modules.

ffmpeg with hardware acceleration is available, see: https://github.com/jocover/jetson-ffmpeg
(there's also the NV prebuilts of an older version of the patchset at https://docs.nvidia.com/jetson/l4t/index.html#page/Tegra%252... )

FWIW, I got a review unit and it ships with a much lighter desktop environment (LXDE) this time and is has a swap file enabled by default. I guess that was needed to ship a 2GB version, but overall it seemed a little better thought out. They also include a wifi dongle in the box. It still only has Python 3.6, but OpenCV and numpy are pre-installed correctly this time so you don't have to compile them which is an impr…
Do you know who I could contact to request a review unit? (if you can share ofc - email in bio) I have an open-source Jetson-related project that I think the new model could be useful for.
Email me (info in bio) and I'll see if I can help
Re: Nvidia announces Jetson Nano 2GB, a single board computer
#130I want to setup something like this for my daughter's primary grade school meetings using Zoom. Any suggestions? Are the Pis or this device up to par now for such use case? I totally do not like Chromebooks, and standard laptops are an overkill.
Why though?
If your goal is just to run zoom, you are better of with buying some used usff pc, having ability to install x86 OS and having more cpu power in similar, if not lower price point.
Of course, if you just want to buy a jetson and just looking for some reason to, that's totally fine too :-D
