Thanks…
I restarted the mirror manually with ‘npm start’ in a terminal window. I have a ‘batch file’ on the desktop that I usually use to start it and that window disappears pretty quickly.

That should give me an idea of what is happening or at least what question to ask next.

I have an issue where my mirror goes black and the cursor re-appears. i give me “Dev-tools was disconnected from the page” and then q takes me back to the RPi4 desktop.

Is there a log?

Has anyone developed a module to display the callerID log from Google Voice?

I had the same question when I started work on my ‘mirror’ earlier this summer. I had purchased a HP monitor and found a link for 3rd party recyclers to properly disassemble and recycle the various monitor parts.

I used the same search term (except Dell not HP) and found this:
Dell Monitor Disassembly

I have a hypothetical / non-hypothetical question:

If I download a module… i.e. git clone (something something something) and then it requires a ‘npm install’ to install the dependencies, properly edit the config.js file, and then decide, for whatever reason, I don’t want to use that module.

If I strip out (or comment out) the module’s entry in the config.js file, what happens to those dependencies? Are they forever on my SD card? Are they excess clutter?

@sdetweil That’s interesting, and disconcerting, about the Win10 SSD problem.

How long do you estimate that your cards last?

Does reading the card inflict damage the same way as a write would?

I think I will also keep at least one cloned SD card handy.

My understanding is that that micro-SD card problem is particularly vexing for the the photographic community. I told my daughter, a part-time pro photog, that I was buying another couple of micro-SD card for my PI4 and she warned me about that. There are some real horror stories associated with that issue - think weddings.

@djkj84 I had this same problem on Win7.

I searched the forum and found this post by @sdetweil…

fix

What Sam said… I’ve just got an extension cord with 3 outlets and then I bought a 1 foot power cord for the monitor’s power supply, a 1 foot USB-C cable and a 3A wall wart so that I didn’t have so much coiled up cable behind my ‘mirror’.
