javeryh:
I finished cabinet #2 over the weekend so both of them are 99% complete. They look great and they play great but the amp and marquee light still do not react to the pi being powered on and off via the SmartStrip on BOTH cabinets. So I do not think it is an issue with a malfunctioning SmartStrip. I've used them on multiple projects though and never had an issue.

I've been researching and I think I might have figured out the problem but I have no way to test without spending some money so I'm hoping someone here might know. I installed a "safe shutdown" script on the pi by modifying "sudo nano /boot/config.txt" and adding these two lines to the file at the end:

--- Code: ---#shutdown button
dtoverlay=gpio-shutdown
--- End code ---

Bridging GPIO3 and Ground (pins 5 and 6) via a momentary pushbutton shuts the pi down. Pressing it again will turn it back on. HOWEVER, I think this is only putting the pi to sleep and it is still drawing power, which is why the SmartStrip is not working properly. There is something called a Mausberry Circuit that purports to actually (and safely) turn the pi OFF - not just put it to sleep.

Before I drop $25 on this thing, does anyone know if this is true or if shutting the pi off would fix my problem? :cheers:

I think you are right about the power.

I remembered Da Old Man posting about switching off his in a jukebox project.

Haven't gotten to play with RPi yet but looks like you are correct about it just sleeping and not fully turning off without another circuit/device.

Thanks bobby - I'm going to ask Da Old Man if he sorted it out. Based on his post and the description of the ATXRaspi that he linked it seems like cutting power completely is something these boards are doing that my setup is not. I really hope it is this simple to fix. I'm willing to spend the money at this point to stop thinking about it. ;D

Well I just dropped what is hopefully the last $40 into these stupid things and bought 2 Mausberry Circuits. I really hope they work. Turns out the pi draws about 70mA when “off” so the SmartStrip will not know the difference. The Mausberry Circuit is supposed to cut power completely once the button is pressed.

This is the last thing I can think of and if this doesn't work I'll have to tell my brother-in-law that you need to flip the switch above the power receptacle on the back of the cabinet to power on and then press the power button for the pi to shut it down and then flip the switch on the back of the cabinet to power off completely. If this is what ends up happening... they are going to eventually fry the microSD card. At this point I'm wishing I bought a miniPC with Windows 10 for like $100 instead of messing with the pi at all. Live and learn I guess.

Once I get the Mausberry Circuit installed and assuming it works I'll take some final pics and film a brief walkthrough and be done. :cheers:

javeryh:
The Mausberry Circuits I ordered FOUR MONTHS AGO finally arrived. Now I need to relearn what the hell I did to set up the pi4s in these cabinets and get the power situation sorted out. If this doesn't work like I am hoping, I am still calling these done and will deliver the cabinets sometime in July when I make a trip up to MA. They are taking up WAY too much space in my basement.

I need another project...
