        It's good that the Nano is guaranteed for sale until 2025.. I hadn't realized that.

          the fan listed in the bom here: BB AI cooling Addon board available
          is the one that fits on the heatsink that is mounted on the BBAI as default.

            Have you had any contact from BB themselves on this ipv1 ? As you have helped bring the issues to light perhaps they could ship you a new board as way of a thank you?

              Nope. I just expect the board to perform as advertised.  The "AI" in the name seems to imply it is designed for AI, meaning Artificial Intelligence.  Or, are you saying it stands for something else?  Chip longevity is only valid for currently produced products and for a specific support lifestyle, or in cases where a mature device is mandatory by spec;  not typically for new products in this particular space.

                I think the board will work for AI applications..

                It's predecessor was the BB-X15, powered by some high-powered rocket : )

                 

                Back at school, we were taught there used to be some cheerios commercial about feeling groovy, and one person sued the manufacturer because they didn't make him feel groovy in the mornings. The product is different but the concept feels the same : )

                  jomoenginer , I understand the frustration, especially when we want hardware to work and just work, and work as advertised.

                   

                  I think that with the BeagleBone range of hardware it's pushing for something different than with the repeatedly compared nVidia board and that it is open source. Unfortunately regardless of people's opinion and view of open source, that introduces the challenge of it being supported and it relies on the generosity of people with their time and effort to support it well.

                   

                  This isn't too different from some other boards that are released that rely on the generosity of the Community to support them, and if someone doesn't want to support it, dare I say it, they're free to walk away, and I agree there's some element of expectancy to pay for a product and have it working to a level - and I would suggest that there are products out there which meet that criteria.

                   

                  BeagleBone gives you the opportunity to get into the hardware on a level that proprietary hardware doesn't, and I would personally suggest that's partly what you're paying for, and it means you have to work a bit more at it, though you can then turn around and say "I did this, this is my cred" and share it, and be appreciated for it. To me that's part of the community and part of open source, you may not agree however it is what I've seen as the ethos behind most open source hardware and software products and it's a challenge to the ecosystem regardless.

                   

                  This's why we're looking at trying to solve the problem rather than focus on the flaw of the problem and pin someone to it for being responsible, we know what the problem is, we can find a solution and then hopefully the next problem is more a case of "do I put an if statement here?". If we hit a hard wall then we can go back and say it needs changing.

                   

                  Does that make sense? Help if you can, you don't have to, and we hear you on the issues.

                    Maybe we need a 'BB-AI accessories' page, to stop abuse of your post Inderpreet.. : )

                    I've got the ZH shellZH shell and the ZH crimp pinsZH crimp pins (I figured I'd want the serial console while powering up the first few times, just in case there's any issues) and the crimps are quite small : )

                    There's pre-crimped connectors with wire ends on ebay, but longer delay to get them..

                      Can confirm, the serial console's very useful:

                        Parcel arrived with my USB-C cable so onwards:

                        Some thermal paste and a 12v fan and I'm finally powered up

                        Temperature measured using gdstew help in Reading BeagleBone AI Temperatures and comes in after 10 minutes at a stable 32 degrees centigrade

                            Thank you clem57 .This way also doesn't void the warranty, although I very kindly got sent mine from Element14 to test out and so that puts me slightly out of any 'claim' loop if it failed.

                             

                            The current stumbling point would be if I knock anything and don't notice the fan isn't directed at the heatsink. And I also am using 12v so need another PSU. I'll mount them on a baseboard to mitigate against the first risk. The second and any size issues aren't really a concern for me as I only want to experiment into AI - understand how I can make algorithms to identify those pesky Box Moths while rejecting other insects.

                              Hi Rod,

                               

                              This is awesome!! I'm looking forward to powering it up this weekend too - I'm off to the shed to mount my fan/heatsink too.

                                Thank you Shabaz,

                                 

                                It has been powered for a few hours now, I upgraded the Debian OS and I am now installing OpenCV. The temperature is still reported as 34-35 degrees C...the slight increase probably due to the ambient air temp rising slightly through the day.

                                 

                                I haven't added an SD Card either at this point. That decision might cause issues as I get into processing data.

                                  On the subject of cooling there is an ultimate solution, literally, where the entire board is immersed in a non-conductive cooling liquid such as this one from 3M: https://www.3m.co.uk/3M/en_GB/novec-uk/applications/immersion-cooling/

                                   

                                  Pump the liquid around the sealed enclosure and through a large external heat exchanger.

                                   

                                  Now, where was that reset button? Oh yes, inside the sealed case
