I wonder what Tim and the rest of us can do to improve membership and more importantly attendance at Technocopia? Is it too far for people to drive? A bad day of the month? A bad time frame? A bad location? We've been trying to keep the remote jitsi stuff working, but technocopia is a bit louder where we sit and meet, and a bit harder to get good sound both ways. I'm hopeful that we can get more people in person, assuming we know what people want? I personally need to come up with an update for my talk on KiCad, updated for version 7. Could anyone do a talk on scribus? Or inkscape? Or do people want more low level linux talks? What do we offer as a group that keeps bringing you back? Or not? Does there need to be more of an agenda? Please give your feedback! John

Yeah, I forget exactly which version I had, probably a 1gb v2 or v3. I've had several die on me for various reasons. Mostly I think it was the power regulator chip being a bit intolerant. But I've also lost a BeagleBone Black (nice SBC in general) but have a Model 3 B (made by Sony) running in my garage doing PiAware data collection, and it gets hot in the summer there. So I really think it was a power blip which killed my unit. > For what it is worth, here are some notes on the RPi 5 cooling. > Note that not of it talks about real operating temperatures, just > when the fans turn on and by how much.

I'm not doing anything in my remote site units, they're jsut linux nodes I can login to and then run commands on to diagnose network issues. Starting to think about getting an old PCEnginge's board and using that. They're really solid, low power and last forever. I've got two of them here at home, one running my firewall, the other running TP-Link Omada software for my TP-LINK WAPs and Switches unified management. > You may know or have thought about all of these things. > md > On Thu, Jan 4, 2024 at 7:00 PM John Stoffel <john(a)stoffel.org> wrote: >>>>>> "Tim" == Tim Keller via WLUG <wlug(a)lists.wlug.org> writes: >> So after buying a 4gb model..

John, You did not say what version of the RPi you had in the closet, but many of the early ones had an ambient operating temperature of 40 degrees C (104 F), which is really not that hot. As you probably know, beginning with the RPi 4th they started talking about needing fans as well as heat sinks. If you were doing any heavy work on the Pi and did not have it set up to throttle back if it got too warm, it could have easily fried itself. For what it is worth, here are some notes on the RPi 5 cooling. Note that not of it talks about real operating temperatures, just when the fans turn on and by how much. What if the surrounding temperature is very hot and the heat sing and fan can not cool the SoC enough? https://www.raspberrypi.com/documentation/computers/raspberry-pi-5.html#coo… Some manufacturers of SBCs offer an industrial or even a military version of their boards which can have higher ambient temperatures? On the project I am working on in Brazil we test the units to work with just a heat sink, not a fan, of 70 degrees C (158 F) On another note, the first RPis also did not do very good with ESD (Electrostatic Discharge). We had 12 Rpis die in the lab while we were working with them, versus none of our boards where we had put in some ESD protection. Finally, many of the first RPis did NOT have very good power management. Depending on how much current was pulled off the peripherals the CPU could just be starved or too much power pulled through the board. You may know or have thought about all of these things. md On Thu, Jan 4, 2024 at 7:00 PM John Stoffel <john(a)stoffel.org> wrote: > >>>>> "Tim" == Tim Keller via WLUG <wlug(a)lists.wlug.org> writes: > > > So after buying a 4gb model..

So after buying a 4gb model.. Logan found that Adafruit is selling the 8GB version for the same price.. so I'm getting the 8GB version. I hear you with the NVME I/O. NVME is really the only way I fly when it comes to doing stuff that needs I/O. Greg, I'll need to see what an NVME adapter costs. But honestly, to really use a pi as a desktop, you need real storage.

Re: I just bought a Pi5.. we'll see if I actually get it.

Tim, Here is a Tom's Hardware report on several "benchmarks" between a 4GB and 8GB Rpi 5 https://www.tomshardware.com/raspberry-pi/raspberry-pi-5-4gb-versus-8gb Their overall conclusion was that for most uses the RPi 5 with 4GB will be fine. Probably if you keep 100 tabs open on your browser YMMV. I have rendered and received the PCIe daughter card that allows you to attach a 1TB nVMe M.2 memory card, supposedly with 5000MB/sec read and write (although I do not expect that I will get that through the PCIe on the Pi 5. I have to have some time to put everything together, but I should be doing that in the next couple of weeks. You can probably find others who have done it already with some decent search queries on the Internet. Here is one I found from Tom's Hardware: https://www.youtube.com/watch?v=EXWu4SUsaY8 I will tell you that when I switched from a SATA 3 SSD to a nVMe M.2 card on my laptop the change was "breathtaking" on I/O style of loads. I will never go back. md On Wed, Jan 3, 2024 at 1:19 PM Tim Keller via WLUG <wlug(a)lists.wlug.org> wrote: > They say estimated delivery of Jan 9th - Jan 11th.. So, who knows..

I just bought a Pi5.. we'll see if I actually get it.

by Tim Keller

They say estimated delivery of Jan 9th - Jan 11th.. So, who knows.. I bought the 4GB model, so it should be functional as a desktop, my plan is to experiment with it as a daily drivers. Beyond that, what do people think would be a good benchmark to experiment with? Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".
