Re: rsync failure due to memory issue - workaround?

What model Pi and how much memory are you using for the GPU? What else do you have running?

Re: Prevent SD-Card Corruption

It' isn't a big problem if you have a backup/restoration plan (and the backups!). Plan ahead! Usually,the people who moan and groan about corrupt SD cards are the ones who just lost a $#!+load of valuable "stuff" and didn't have a "good" backup strategy. By all means, do whatever you can to avoid da...

Re: Finding the max (or near max) overclock for multiple RPi3B's

If there is, I haven't found it. I have 4 Pi 3's - 3 of which overclocked to ~1.35GHz. The newest one overclocked to 1.43GHz. All have heatsinks and fans and I try to keep the CPU temp below about 45' while running a mainframe emulator and my weekly full backup of the entire system. That pushes the ...

Re: SSD bad block

First off - if you have any "critical" files on the SSD, back them up to another device. (Assuming you don't have a current or recent backup) The SSD itself might have taken a one-time hit or it could be a warning that it is or will be "Not long for this world". Then you can perform whatever testing...

Re: Sunfounder IR Reciver not detecting any remote control input.

I can only suggest there is a problem with the cobbler/cable or the module itself. Take the cobber (and ribbon cable) out of the mix and wire the module directly to the Pi. Before you connect the module, run the pintest program to be certain the Pi itself is workinng properly. Note that you will nee...

Re: Sunfounder IR Reciver not detecting any remote control input.

Do you know that the remote is working? Point it at a cell phone camera and you should see it light up when you press a buuton. Or try any other remote you have handy. Check your wiring carefully... It's easy to to miss something simple like missing a wire or being off by by a hole on a breadboard..

You need a better PSU and/or cable if you have a near constant lightning bolt/blinking power LED.

Re: Power bank to run the pi 3

How long does the Pi need to run?

I would set up an SD card with whatever you need to run and try it. Be prepared to sacrifice an SD card or two. Also bear in mind that as the powerbank ages, it will take longer to recharge and provide less run-time, so you may need take that into account as well.

Only time I have seen those symptoms is when there is some kind of problem with my primary storage device - in my case /dev/sda.
Does dmesg show any errors on the sd card or did the update/upgrade show any errors?

Re: Display stopped working with VGA to HDMI adapter

If the HDMI-VGA adapters have their own power sources, do not overlook the possibility that the PSU has "gone bad" without totally failing. A meter (and knowing how to use it!) is pretty much a "must" for anyone working with Pi's.

Re: Dynamic AND static IP for Pi Zero W

An easy way to have 2 IP addresses is to have your router assign a DHCP adress as usual (wlan0 or eth0) and then set an IP address (with ifconfig) for wlan0:1 or eth0:1. If you do it that way, make sure you stay away from the pool of DHCP addresses that can be assigned, otherwise you may end up with...
