Re: This Update does NOT look Right

There seems to have been something in flux recently. I just got a shed load of 404's, "not found", doing an upgrade immediately after an update on a Pi 3B running Stretch. A second update, then a following upgrade, listed different files to the first. That seemed to work just fine but did take some ...

Link Spammers

One trick spammers use is to register and do nothing. Their trick is in getting their promoted web site noted, picked up by Google and other crawlers. They often do that by hiding links in plain sight, in signatures, home page links, interests; things no one will usually see or spot unless looking a...

Re: Broken python (??)

Why were you trying to reinstall Python; what was the issue which drove you towards doing that ? It could be that whatever broke Python in the first place is also what is causing things to no longer work with a reinstall. It might be worth trying a reinstall on a freshly installed system to see if i...

I don't think there's much to add other than to say "me too!"
It would be worth checking if a newly downloaded NOOBS, PINN, Raspbian Lite or some other installation put on a fresh card does boot or not, to rule out that it's not a RetroPi related issue.

Re: PoE HAT - Usage scenarios

£18 for a fan? A speed controlled fan, with speed control already baked into Linux and the firmware. With PoE if one chooses to use it, pre-assembled, tested, with warranty, and with an easy to use HAT fitting, and all the fixtures. Sure, some people could build the same themselves, but most people...

PoE HAT - Usage scenarios

Is it possible to connect the official PoE HAT to a Pi 3B+ and power the Pi through the micro-USB rather than Power over Ethernet, to allow the PoE HAT to be used purely as a Pi-powered software controlled fan controller ? Or, to allow a Pi 3B+'s use both when PoE is available and when it isn't. Whe...

Re: Help/ideas on building a web interface to a python program

I'm not sure directly accessing a gui would be useful, this pi doesn't run an xserver. That framework is not using xserver just using normal HTTP. You connect to the Python program from a browser and it draws its buttons etc on the browser page. So like a normal native GUI but remotely accessed thr...

Re: No boot after raspi-config change in a new Raspberry Pi 3B+

Sounds like another Pi 3B+ which was working but now inexplicably isn't.

It would be worth contacting your retailer to see what "return, test, repair or replace" service or warranty they offer.

The offline versions will continue to work, but we'll be in a position where the kids are using 3 at home or on desktops and then have to relearn for the older versions when on the Pi. It's going to be even worse than that. Until required hardware extensions are ported kids will have to move to usi...

Re: Serial logging project

1) it would be USB serial cables for both interfaces for me. First they are immune to any changes in Pi system clock throttling which saves having to configure system operation and, if anything electrically goes wrong with the interfacing, you will hopefully only have to replace the cables, and that...

I have a strong feeling of deja vu that I have answered a very similar question in the past so a forum search might be in order.

Failure mode 2 - That describes my RPi. Can you tell me more about this 3V3 supply please? I have a multimeter. Where do I measure this 3V3? Measuring between Pin 1 (3V3) and Pin 39 (0V) of the 40-way GPIO connector is probably the easiest to avoid shorts to other pins. You can place strips of card...
