Re: Trying to turn monitor on/off with webcam motion detection

Check in the task manager to see if the applications are still running but not visible. It could be switching desktops or something while you can't see what it is doing. Something else completely separate from vcgencmd display_power could be doing that. Try wiggling the mouse periodically to see if ...

How to remove a start menu item

I installed omxplayerGUI a while back, and with it came Minimal Kiosk Browser. Later I uninstalled omxplayerGUI and MKB, but MKB's menu item still remains and I can't figure out how to remove it. Yes I am sure I uninstalled MKB, because when I click on the menu item, it shows 'invalid desktop item' ...

It played videos fine, set at 64, before the upgrade; why would that change with the Chromium update?

Re: Raspberry Pi is unusable as everyday computer

Whether or not a Raspberry Pi is sufficient for you depends on what you prioritize. I prioritize simplicity, changeability, responsiveness, and reliability. Some people prioritize "brute force" computers with more resources, but they are usually hands-off in comparison to Raspbian and have a very co...

To clarify, I use dtparam=audio=off in CONJUNCTION with a USB sound card. If you don't have a USB sound card on hand, turn on the built-in audio chip on again. Try setting the ALSA default directly, instead of through the raspi-config tool. Steps to try: 1. enable the onboard audio chip in config.tx...

Re: Audio works with HDMI, audio does not work with 3.5 mm jack

This answer is based off of my experience with a Raspberry Pi 3 running Raspbian Stretch. As far as I understand, raspi-config just sets the ALSA default audio output. I've had some programs ignore the ALSA default, others refuse to play if the it is set to 3.5mm audio jack. In my quest for consiste...

Re: Moving from a 8GB micro SD card to a 32 GB micro SD card

You can copy to a larger SD Card using the SD Copier in Raspbian. "Removing" NOOBS is a bit more problematic. It is possible to move a Raspbian installation to a new SD Card, but not exactly straightforward, The easiest is to do a fresh installation of Raspbian (any flavour), then use `rsync` to co...

Both these below solutions assume you are running your Pi 2 off the built-in card slot, and you have t...

Re: What cable can I use to connect these 3 devices

The connectors on the cable ends internally connect together contact positions which are ground on the PC and drive. The corresponding positions on a RPi GPIO header are not ground and connecting them together causes electrical damage to the SoC which cannot be repaired. If unsure, count 10 ridges ...

Yes both devices could be relying on the same pins, but I'm assuming gullbaek has already sucessfully tried them stacked. Witty pi has male headers on one side and female headers on the other side. Because of that, the cables will physically work. I'm not so sure about electrically work though... Gu...

You never want to power a motor directly from a GPIO pin, it won't work and you risk frying your Pi. PWM stands for P ulse W idth M odulation.
