Which Raspberry Pi 5 AI Hat are y'all using?

[James H Phelan]

Is it this one:

THose Pi hats are not very cost effective in terms of performance per dollar.  Compare the linked hat to an Nvidia RTX 5060, which is roughly the same price.   Maybe you might need the AI physically on the robot if you were concerned about WiFi latency, but the reduced computation time would make up for it

I have an old Corel TPU that is slower than the hat but fast enough to run Yolo on a live video stream.  I think that is a good justification for localAI, where you have a huge amount of data but only  light (by today’s standards) amount of computation.

Another tiny-scale AI processor I’ve played with is a security camera.   Many of these sell for well under $100 and have built-in AI.   More people should use these for robots.  They are Ethernet interfaced so they work with any computer and send variable resolution streams and as said can do on-borad processing and typically the setup is via a web page that the camera hosts.  mass production keeps the prices low.   I have two of them, one has built-in plan/tilt.  But I find users don’t like them when they are indoors.

But the best “hat” is this very old Xeon-based server that came with many PCI slots and a 800W power supply.

I was also shocked at that price (much cheaper not long ago), I know AInflation and tarrifs but maybe check here (if you are leaning that way):

Also, in that price range, the NVidia Orín Nano Super dev kit might be worth a look for on-robot applications?

Ken,

The updated JetPack and overall price for the Orin Nano is intriguing.

My old Jetson Nano is an orphan.

The Orin Nano is a power hog and would likely require a second battery pack.  Too much for Stormy the Stingray but a consideration for upgrading my NASA/JPL Open Source Mars Rover Audacity to autonomy.
