I wanted to highlight a raspberry project which I think is amazing. it's a Hermes SDR crunched into a pi-hat and it's incredible. I dare say it outperforms with SparkSDR the other radios I love

Thanks Ron. I'll take a look at the README file. 73 - Scott/KK6DZ

Folks, I'm enjoying using Home Assistant, but and fun ham radio projects for the Pi4? Thank you Ed

I built one with a Raspberry Pi Zero W, so you shouldn't have any trouble at all. Video: https://www.youtube.com/watch?v=-mksymTUKSw ( https://www.youtube.com/watch?v=-mksymTUKSw ) 3D display case if

David - I also added a software debounce to the command to add some noise immunity. What I like is that this approach acts as both a power down and power up using the same button. One of the drawbacks

I eventually bought a CrowPi-L by Elecrow (https://www.elecrow.com/crowpi-l-real-raspberry-pi-laptop-for-learning-programming-and-hardware.html) with a Raspberry-Pi4B and 8Gb of RAM. I have installed

Hmmm.. that's a new one to me and thanks for mentioning it. That said, I use a modified version of this older-style shutdown method mentioned at

I needed an easy power ON/OFF button on my RPi4B and came across this approach at https://www.stderr.nl/Blog/Hardware/RaspberryPi/PowerButton.html which worked great. It does the equivalent of

It would really help if you would quote the message you are replying to. Something like this going out to a large group probably doesn't tell most people anything. Mick - W7CAT

It's okay. We all may mistakes. Getting the wrong group or a private message that gets sent to a group.? : ) Mick - W7CAT

Makes sense. I guess I wasn't thinking too hard about it! Thanks - Scott

I meant it has nothing to do with a RPi4. Scott
