Re: Looking for a mounting solution for RPi (in case)

.We've settled on a secure modular case that has 2 screw mount holes on the bottom, so I COULD just grab a hunk of wood and some screws, but I was hoping to find a more elegant solution that would also help organize all my cables. You can tack the cables to the wood to keep them organized. For eleg...

It would appear to me your workgroup name has more than 15 characters. Does that really work? Also, does anyone actually pay?

I would check that all Pi computers have the correct time and date: DNS servers don't work very well when the time is off by a few years or even hours.

The B+ had a AP2553 acting as a reverse-current blocking device.
Apparently the 4B does not.
4B has an AP2552 which is an active low enable version of the AP2553.
How does this work? Does it prevent problems when the Pi is running from it's own power supply?

Are you sure gigabit Ethernet on the 4B uses PCI Express?

For a while the 3B+ was selling for US$ 25 in many places. At that price, depending on your needs, it's a great option.
