The ACT activity LED is too busy, so I chose the PWR led (sorry PiZero). I think I remember doing this a few years ago and once you've taken control of the green led on the PiZero - it doesn't get activity updates until the program hands back control And IIRC, the PiZero LED is inverted compared to...

Top left and bottom right
Although long leads on either mic solution are not ideal - they want to be as short as possible

There is a lot of example out on t'internet but maybe best way is to use a library to do the work for you as it deals with a lot of issues that can arise if you roll your own code

Because you've got 2 network connections - one to an Ethernet LAN and another WiFi to a router , your Pi computer is probably getting confused as to which one to use to access the internet as both of them are active Computers use a term called metric to decide which is the best path to use and norma...

According to the github repositry - its not being actively maintained so your prob going to be out of luck

https://github.com/Lawouach/WebSocket-for-Python

Prob best to try and find another library that does what your after

Cheap £1 ones work fine

So I'm wondering if Raspbian has any specific package advantages or custom tweaks compared to other distros on that front?

All GPIO stuff is developed and tested on Raspbian

The fact that it works on other distro's is just fortunate

Sorry - I didn't read all of your post that you can get it working!

But what I do do with long chains is power the 5V on strip directly from a hefty PSU and not try to drag several amps thru the Pi 5V pins

Got zillions of WS2812 connected to millions of Pi - never used a level converter

(Might have slightly exaggerated the numbers)

There used to be code on the net for a Pi to detect when an Amazon Dash button powered up and connected to a network - might be worth trying stuff like that out

Maybe you've developed a hardware problem with your HDMI lead?

I think the raspberry pi foundation makes deals with some non-free software vendors to include their software in the raspbian repo or NOOBS, and they get paid for including their limited trial versions. RealVNC is one of these. I'd be much more inclined to believe that RealVNC supply RPi with their...

This may be the answer to non soldered GPIO pin headers

JFI They are excellent if just plugging an add-on board on once and leaving it but I tried a couple of them out and the pins have a tendency to come back out with repeated use

When connecting to a Windows PC nothing else should be plugged into the Zero I think they meant their Windows mouse and keyboard died on them to OP - I think you've got a short between your 5V and gnd (most probably between pins 4 and 6) If you can sort that out (and any other shorts) then it might...

I just tried running npm install noble --save on my Pi4 and it came up with a load of errors relating to bluetooth-hci-socket Looking at the project link, other people say it didn't work a year ago either So it probably an old project that used to work with earlier versions of Raspbian/node and the ...

TBF to the OP the text

The Raspberry Pi is a small computer that can do lots of things. You plug it into a monitor and attach a keyboard and mouse.

doesn't say to put the a card into the slot (or even to plug in a power supply)

So maybe a small change wouldn't go amiss

I think the OP makes a legitimate point in that there doesn't seem to be a video conversation program for the Pi to enable it to talk users on other devices. But, like many other users, I gave up on Skype a number of years ago and use WhatsApp on my phone for video conferencing so it isn't a deal br...

I'm not an expert in this area but pauses in GUI desktop use on computers are usually caused by something else taking some time One of the most common reasons is that the OS has run out of RAM and is swapping stuff out from RAM to external storage etc This would explain the OP issue and might explai...

The OP says they are running the 328 from a 3V3 supply

So there isn't a 5V issue at stake here

mattmiller

The Atmel processor doesn't run at 3V3

It will run at 3V3 - just not at high clock speeds

I've just put two and two together after realising what this meant https://www.raspberrypi.org/forums/viewtopic.php?p=1501760#p1501760 so I just commented out the #dtoverlay=vc4-fkms-v3d and set my framebuffers back to the size I like (so that the Pi VNC window sits just inside my main PC window res...

So, there seems to be a shortage of PiZero in the shops in the UK .......

I think your wish has been completely granted. Not yet is hasn't :) What we are after is the facility to simply add a script xxx.sh to the /boot partition and have that be run on first boot (preferably after all services are up and running) Jim's is the closest contender so far Interesting to find ...
