Re: Current State of Raspberry Pi 4 Software and Hardware Support

Raspberry Pi 4 Model B+ I have a feeling that an enhanced model of the Pi 4 could come out soon, due to previous problems with the temperature of Pi 4's CPU. Maybe it won't be called B+ (see: Raspberry Pi Zero versions), but you get the point. Do you think this is a silly thought, or might I be int...

Re: Raspberry pi 4 and fan

The fan should not be connected directly to a GPIO. It is likely to draw too much current, and may produce back EMF when switched off. Either of these will damage the Pi. The Amazon listing does not give a specification for the fan supply (neither voltage nor current). You might get away with conne...

but looking at the same file on the old SD card, it doesn't contain any of that stuff (well it does, but it's all commented)
Without specifically checking...that file is almost certainly owned by root. Prefix your editor command with "sudo" to edit it. E.g. sudo vi /etc/dhcpcd.conf

Re: Second Gigabit for PI 4B

The USB C port on the Pi 4 is strictly a client port (device-only) at USB 2.0 speed No, it can run in Host or Device mode. See https://www.raspberrypi.org/documentation/hardware/raspberrypi/usb/README.md#overview_pi4 That says that it is intended to run in Client mode. Not that it can only run in t...

Re: Western Digital WD Hard Drives

The PiDrive cable was the best bit for me - it delivered the power direct to the hard drive and then to the Pi, nicely getting around the Pi's USB power output limitation. You could use it to attach any USB 3 hard drive. https://thepihut.com/products/western-digital-pidrive-cable?variant=2568754151...

There is a requirements conflict between "nice" and "compact". Compact keyboards are, generally, not nice and nice keyboards are, generally, not compact.

Re: one more time: disable screen saver

The problem is that, if you have a local autostart, it overrides the global one. So you have to either execute the global one explicitly inside the local one, or copy everything from the global autostart to the local one. This leave an easy alternative...

I'm not surprised. The proportional popularity (so far, at least) of the 4GB model exceeded RPT expectations.
