can take a look at Argon Forty Neo Case. It is a aluminium case with a slide top cover that gives you access to the GPIO. https://www.argon40.com/argon1/argon-neo-raspberry-pi-4-case.html Do you have any data on heat handling with that case? It does not appear to have the pillar that (in the Flirc ...

See https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=248516 . The bottom line is that provided you get and use a cable with narrow connectors referred to in that thread and in the Flirc case FAQ, there is no significant problem. Obviously, you have to connect the cable before you assemble the...

The default settings for the timeout within the LightSensor code may not be long enough for your environment (they seem to assume either a very well illuminated environment or a very sensitive sensor). Try playing with the optional charge_time_limit argument. I got good results in a normal home envi...

The biggest problem is that you are unlikely to get a full 25W from your solar panel unless you live in a very sunny climate. From my own experience in the UK with solar panels on my house I rarely average more than 60% of there total output in the summer and considerably less in the winter. Are yo...

it would be really nice if there was a Pi4 Lite.
sort of cool and usable with HATs and out of the case.
the processing power can be lower, as long as it can still run the usual stuff. just without the heat.

Isn't that called a 3B(+)?

Unless you have also been messing with my /lib folder

, the strange name is correct. I have a file with precisely the same name. Why do you think that you renamed it?

Hopefully just something stupid I have done. I just want to see my RPi (3+B) in the list of computers when I look at the network display of devices in Windows 8 or 10. I can ping the RPi with the DHCP assigned IP(4) address. I can see the Shared Folder contents on the RPi using Samba. But I can not...

@jcyr: your issue with sudo reboot does seem to be specific to your setup. On my Pi4, running from an SD Card, there is no problem rebooting after the update, and I assume that the other positive responders in this thread also had no problems.

More searching found pywemo (https://github.com/pavoni/pywemo), which provides the facilities that I need under Python 3 in a usable form, though you have to do some spelunking in the code to work out how to use it.

Has anyone any useful experience with running the ouimeaux application (which provides a Python interface to WeMo devices) under Python 3.x? If I use pip to install it to run with Python 2, everything seems to work as documented, both for the standalone CLI 'wemo' application and when you import the...

Pads are sticky and can be used to secure a heatsink to a device. I doubt a pad would stick if one (or both) surfaces had paste applied but I've not got any pads here to waste trying it out. PeterO Don't generalize from limited experience! Pads may be sticky and act as an adhesive connection betwee...

Would be nice to see if you could use the stock thermal pads in combination with thermal paste, to see if that improves the heat transfer? Do you understand the purpose of thermal paste ? The primary purpose of thermal paste is to fill in small irregularities in two imperfectly mating surfaces so t...

I am working on a raspberry pi 4 free NAS server, and I thought just for extra safety I should install a UPS, I found a UPS on aliexpress, but I'm not sure if it wil work (or not break) the RPi.

There's a FAQ on the Flirc RPi 4 case page where question 9 specifically adresses the gpio ribbon cable issue: I'm having trouble fitting a standard IO Cable for the Connectors, do you have a recommendation? Yes, this one works perfectly fine: https://octopart.com/search?q=IDSD-20-D-06.00 I haven't...

The Flirc Gen2 is made specifically for the Pi 3B and 3B+ models, and it has an internal post to transfer heat away from the SoC. It has 2 thermal interface pads, a thin one for the 3B+ model (and newer 3B with 2837 B0 SoC), and a thicker one for the older 3B. There is a slot on the bottom of the F...

It is now nearly September, and my 4B has been regularly updated/upgraded since I got it, earlier this month, but I am also seeing problems with serial transmission with a small beta HAT that uses UART0 and works perfectly on a 3. I don't have an oscilloscope or another serial terminal I can test it...

But then...I tend to nitpick the very common but badly used technical terms. To take one that shouldn't be a problem here, there is no such aircraft as an "Me-109". There was a "Bf-109" and an "Me-262", but no "Me-109" in spite of the Bf-109 having been designed by Willy Messerschmidt. My favorite ...

See Andyroo's answer when I asked the same question ( https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=246667#p1506293 ). The added requirement for headless setup in Buster is that the default screen size has to be set for (at least) VNC to work. Both OS versions will autodetect most HDMI mon...

Who actually reads documentation? I generally do that only once I discover my initial assumptions were false! ;) I always read through the entire documentation of a hardware device or software package once. I then generally reread the section(s) on whatever I actually plan to use. I find that enoug...

No, it is used on Windows, but I want to verify its functionality also on Linux. Therefore I have installed the dev stuff on the RPi4 and will transfer thw sources via SVN to it and then build and test the project there. Audio controls are part of the editor too. But it is not a full video editor, ...

I'd say it was a regular case. Just a very well designed one. Looking at the one I have here, the LCD cable and camera cables have exits, and there is an available slot to get a GPIO ribbon cable out should you so wish. Indeed, there is a slot provided for a GPIO ribbon cable, but do you know of a ...

You might want to just look into a Flirc case ($20 with shipping). The top half is all aluminium and acts as a big heat sink(no fan and none needed). For anything pre Pi4 they are more than enough case to keep it cool. For the Pi4 they are right on the edge, for moderate use they are fine. I endors...

What about something like this https://www.mouser.com/ProductDetail/TE-Connectivity-AMP/3-87456-5?qs=sGAEpiMZZMs%252BGHln7q6pm7F1NlCFAzwfeva7z7Ehuec%3D Found by googling "2x20 2.54 female" You'd have to attach your own wires, but the connection itself is very slim. That looks like a ganged connecto...

So to cut a long story short, if your Pi 4 hangs on boot when 2 displays are connected, try a different micro SD card. The cards are different brands, the cheaper of the two is the one that allows the dual displays to work. It seems highly improbable (but not impossible, I grant) that the make or s...
