Finally got this to work, desktop now on official 7" screen, and HDMI. I have delivered the Pi to my children, so can't remember exactly what I did, I think I did apt-get install libxinerama1 Which seemed to be already installed, but is now set as 'manual install' rather than automatic. Found the me...

If anyone in the UK is interested, there have been changes made which mean that the UK Amateur Foundation Licence can be more easily achieved: The requirement for a practical has been waived, and the exam can be taken online ( with invigilation safeguards). I believe there are several on-line course...

Update: Have tried the advice at the top of this: https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=246384 99-fbturbo.conf file doesn't survive a reboot, and only /dev/fb0 exists. I originally thought that my changes to config.txt were failing because the max_framebuffers was in the Pi4 sectio...

More info: Original monitor was DVI, TV is Polaroid. If I power up just the Pi, either screen displays the desktop. Powering the official screen, I only get the rainbow splash on the bigger screen and no further than that - official screen is ok. On the iiyama DVI, and the TV have tried /opt/vc/bin/...

That distance is from the sensor plane to the front of the locking ring.
That's useful, but not quite what I asked, specifically from the sensor plane to the *rear* of the board.

Have dug out a Pi2 attached to the official dsi screen, and updated to the latest full version of raspbian. Power supply is adequate I believe. I have tried various combinations of legacy/fkms/FB from the raspi-config menu: at times the HDMI/DVI monitor works and shows the desktop, but mostly the 4p...

A technical question: there's a drawing of the new camera board face-on with dimensions. I haven't seen a diagram with dimensions edge-on, showing the exact distance from the plane of the sensor to the back of the circuit board/tallest component. I'm thinking about the feasibility of using a HQ came...

Just a suggestion, shoot me down in flames if it's not feasible, 😁; how about attaching something at the *hinge* end of the gates - rather than just open/closed, you could generate a signal proportional to the swing of the gates. Perhaps doing both, would show if gate was opened for human/horse/hors...

I was looking for a different example, but could only find this, which isn't the one I vaguely remembered:

Yes, but if you missed it like I did, you might not have updated

This may be old news, but was new to me.

The expression derived from the practice of miners carrying caged birds (such as canaries) underground with them. When the air became noxious, the birds fell from their perches.

I have two TNC-Pi: v1 for the original Pi's, V2 for Pi3 - there doesn't seem to be a version for Pi4, and I haven't checked whether V2 would fit a Pi4 in a full case. For software, I use Xastir. It may be possible to send messages to individual callsigns, I haven't used that feature. The Adafruit ul...

I thought the battery in a pacemaker was guaranteed for life 🥺

Sorry

Many years ago, a company was making devices attached to the optics: each shot was logged, as were bottle changes. This was long before microcontrollers and the Raspberry Pi. The idea was that the management could keep tabs on when and what was sold/dispensed. Of course, you would still have to keep...

There's a guy somewhere on the forum asking if he should get his son a Pi for going to uni. He's going to need a key-ring, isn't he? Giving your son a bottle opener for the university may send the wrong message. I think an official Pi heatsink shaped into the Raspberry logo (along with a 3B+ to ins...

Is it "Never lift more than you can eat",
Or " Never eat more than you can lift"?

The Adafruit Ultimate GPS (Hat or breakout board) also has a 1pps pin, which can be used to synchronise a NTP server, should you wish to build one.
Not required in all use cases, but useful if you want one.

I have used the Adafruit ultimate GPS breakout. The PPS signal is taken from the 1pps pin on the breakout board, and needs to be fed to a GPIO pin, and referenced in your code. I used the instructions here: http://www.satsignal.eu/ntp/Raspberry-Pi-NTP.html#user-mode The GPS hat is probably much the ...

I had something similar: HDMI to dvi lead into a TV/monitor, screen would occasionally flash red intermittently, wiggling it made it better/worse, until I replaced the cable.

Try some other HDMI cables & see if the problem goes away.

paulie

Don't forget that you get a free Pi Zero with every 6 month/12 month subscription to the MagPi magazine.

paulie

It's possible to use an Adafruit Ultimate GPS, and feed the 1pps output into a GPIO pin.
Would this fulfill the OP's requirements?

Pimoroni are awesome for all things Pi (and more besides).
They are based in Sheffield.

Is this relevant?
