Re: Raspberry Pi Zero Overheating + HDMI artifacting & blank

Disconnect all USB attachments and reboot. Add USB devices one by one until the problem shows up. Check the power supply to the USB hub and/or try a different powered hub. Try a different HDMI cable...that one sounds flakey, or you could have damaged the HDMI connector on the Pi board. The connector...

Re: Login issues connecting to raspberry pi files

I'm unsure what you are trying to accomplish here but I have routinely been accessing an RPi on my home LAN from several different computers on the LAN, ethernet and wifi, using ssh. Ssh must be enabled in the configuration but then it is simple to connect with ssh pi@[your Pi's IP or hostname here]...

Re: booting up trouble

Unlikely that the the sd cards are at fault, as all have been shown to work on another system. That a second Pi would have the same problem is unlikely. Still, not all Pi's draw the same power. My money is on the power cord. Even with a properly rated supply, the voltage drop over a thin cable can b...

Re: RPi2 SD card holder does not hold

When I first got my Pi3, I thought the non-locking slot was a "cost reduction". If you change cards a lot as I tend to, it may be a blessing in disguise. I mostly leave my B+ alone in its IoT application so I haven't seen any problem with it yet.

RPi2 SD card holder does not hold

My RPi2 SD card holder catch seems to be broken. The SD card goes in and makes contact OK but the catch does not hold it in place and I have been using a heavy rubber band to hold it in place. Without the band, the card just wants to pop out again. Any way to fix?

Re: Add External Antenna to Raspberry Pi 3

This is going to depend to some extent on your location and your neighbors. The normal output from the onboard wifi is so nominal that unless you are close next door to some one else on the same channel, who is going to notice? OTH if you are using a yagi or waveguide type antenna to extend the rang...

Re: Disabling RPi3 onboard wifi running LibreELEC?

Just ran across your post. I have done this using the console command

Code: Select all

sudo, ifdown wlan0
. It needs to be done every time the Pi boots so you might want to put it in a crontab to get it on a schedule.

Re: Micro sd card

Be very careful of the source...buying these on Ebay, even if labeled Samsung or San Disk, can get you counterfeits. Amazon or other reputable source such as Newegg is a better bet for these. Even on Amazon, be sure they are being provided by the mfgr. and not some unknown source.

Re: voltage too low, faulty USB hub?

If you measure 5.17 v at the hub input, is that under load? If so, your losses are downstream and you should look at the various cables and check their resistance. Short your DVM test lead tips together to get a baseline and subtract that from subsequent resistance readings. If your Pi draws 1 amp, ...

Re: Windows 98 no raspberry pi

Hope you can read English. You have the wrong computer or the wrong OS or both. W98 was built for x86 based computers and it is an ancient and buggy OS. The Raspberry Pi is based on an Arm CPU architecture and cannot run x86 code as in ANY version of Windows.
