Re: Pi 3B - Broken SD card slot

You *could* wire in an micro-SD to sdcard holder, the sort that comes free with many micro-SD cards, to the exposed pads with fine insulated wire. That would act like a replacement micro-SD card slot.

Collectd "Disk" plugin no longer works for later kernels.

This is just an FYI, to save people tearing their hair out, like I did. Due to the format changes in /proc/diskstats with the additional 4 fields, the code in the disk.so module no longer reads any drive metrics for Collectd version 5.7.1-1.1 (Stretch). It's expecting 14 fields and there are now 18,...

Yeah, unfortunately that seems about "normal". I've reworked my "official" red and white case to put a grill and a fan in the top because I was very unhappy with the heat build up.

Re: Installation of mono-complete package caused R Pi to freeze, and now "apt" mechanism seems to be stuck in a loop

Assuming that "top" is available, run that and look at the memory/swap/wait-IO levels. I've had the same experience as you and it takes a long time, a lot of memory and a lot of disk activity. My guess is that it is swapping heavily. On an SD card, this is a nightmare. It's bad enough on my HDD base...

Re: Power input monitoring?

I'm looking for something that can read the actual input voltage, so that when I plug in peripheral X, I can see how it impacts the power available to the board. Examples recently in other threads include DVB-T and SSD devices, both of which question the power capabilities of the supply.

Power input monitoring?

Why not have a tiny USB drive plugged in as your writeable area. This maintains your SD card as read-only.

Be warned.. GNOME is incredibly memory hungry, especially the gnome-shell component.

While I'm sure that it's possible to use it, IMHO the Rsapi is not a suitable platform due to RAM limitations.
