Won't help for SA, but... https://chicagodist.com/collections/ras ... odel-b-2gb On the other hand, they are--again--sold out of Pi4B8. Fortunately, I got an order in when I got notice they had them and have on in transit.

Make sure you use the microHDMI connector closest to the power connector. On the TV, be sure you've selected the correct input before turning the Pi on. Make sure the HDMI cable is firmly seated at both ends. If none of that works, get another HDMI cable to test with. And if you can test with some o...

- Used disk manager in Windows to create an extra partition with the rest of the unallocated space Part of the first boot process in RPiOS is to expand the root partition to use the rest of the space. I have no idea what doing what you did will do the that process. I would suggest installing and bo...

Already been suggested and acknowledged that it would be beneficial. Doesn't mean it's going to happen any time in the foreseeable future. And--FYI--no need for 3.3v connector. Connecting a fan to the 3.3v rail is Not Recommended. 5v, ground, and a GPIO PWM pin could be useful, though. Problem is.....

If you use the *one* USB port on the Pi0W for the HDD, how are you planning to connect the Pi0W to your DVR? May I suggest that some form B-series Pi might be more to the point. Or are you planning to use the SD card in the Pi0W as the back drive?

Also don't embed spaces in parameters unless you enclose them in quotes.

Not to mention that if the error message you quoted is correct, then the command line in your code tags *isn't* what you actually entered.

I did see the lightning bolt icon at the upper right of the desktop. I did not know what it meant until now.

Well... Just in case you haven't read about (because you probably haven't seen it), there is also a red thermometer icon when Pi approaches thermal limits.

My "collection" wont be complete without the RPi4B-1G... :( I have one and, no, you can't have it. What I don't have (yet...it has been shipped) is a Pi4B8. On the serious side, what I don't have (and probably never will) is a 256MB Model B v2.0. Not going to go into the various versions with diffe...

I was testing Kali on the Raspberry Pi 2015 I had with the Sense HAT and it worked but then wanted to keep the newer Pi 3+ for the Sense Hat in the official case. I swapped the two and now the Pi 3 model B V1.2 won't boot with the same power and monitor that worked before the swap. I read the troub...

it is now running on a Rpi 3 and OS is Buster. I hope this is enough take your time for answering, just got an e-mail that the delivery of the case (with fan) will be delayed. Website last week said 5-7 july, now week 30 ..... :-( ................. Best thing to do is to bring your copy of RPiOS Bu...

Now you know why so many of us recommend the official RPF PSUs, especially to those new to the world of Pi.

W. H. Heydt

Well perhaps that might be true but then again, going slightly off topic, if one is talking about having portability, price and power (and perhaps I haven't looked hard enough) why does a desktop computer which is comparatively less expensive than a desktop always have to be seemingly bulky and not...

W. H. Heydt

What you want are USB 3 hubs and USB to SATA adapters. Keep in mind, though, that it's all going to funnel through the same 4Gb/s PCIe lane that the Pi4B uses to connect it's USB ports.

W. H. Heydt

It also would not be as compact, would run far more hot, nor indeed would it be as portable. Price is not the only consideration Price had better not be...compact or portable costs *more*. Running cooler is going to mean running *slower*. [/quote) Does the new macbook run slow and cool? I mean it m...

The Pi4B uses a *micro*HDMI connector. What's more, the RPT markets and inexpensive microHDI to HDMI cable. They come in black and white and 1m or 2m length. From your post, one must presume that you have a spare keyboard, mouse and monitor or TV. One thing you definitely need is a microSD card. It ...

W. H. Heydt

Wow! Look at those goal posts go! Yes technology has a strange tendency to improve (to an extent of which one is sometimes unaware) and one must take account of that. Several of us have been pointing out that what you want to do *isn't* cheap to develop or build. You want tightly coupled 64 cores, ...

OK. I got a RMA to ship it back for a refund. Along with some of the issues with Pi 4 such as the one mentioned in: https://www.raspberrypi.org/forums/viewtopic.php?f=91&t=278702 and possible other issues with the bootloader and micro sd cards over 32GB, OS, etc. I have bought some stuffs from buyp...

You mentioned "only" 100 cores... The current to AMD Threadripper has 64 hyperthreading cores. That gets you 128 concurrent threads. Is that close enough? (If not, just wait for one or two more generations.) Alright then a 1000 lol. Or Shall we let the Americans do it then? Wow! Look at those goal ...

No I am suggesting that if it were theoretically possible someone in government perhaps or from a research organisation might look into it Then why are you trying to interest the RPF/RPT in building the unit blocks of what you're after? Why aren't you bugging ARPA (in the US) or whatever the resear...

Is it not possible for the company to design a specific type of RPi for use in coprocessor/parallel computing situations with one lane or more lanes and then a main board with several lanes? If you want Broadcom to design something specially for you then I hope you've got a several million dollars ...

What about PCIe? The BCM2711 (the SoC used for the Pi4B) has ONE, count 'em, ONE PCIe v2 lane. It runs at 4Gb/s. Note that that is *slower* that the 5Gb/s of USB 3.0. The PCIe lane connects to a chip that in turn drives 4 USB ports. Yes, at least one person has stripped off the PCIe to USB controll...
