That ball used to gather all the dust on the table, and had to be cleaned frequently.

Saved dusting the desk...

Also good for those crumbs when you ate at your desk...

I guess that means the mouse really had large balls!

Before I switched to optical mice, my mouse had only a single ball. I called him Einstein.

My Logitech trackball has to be popped out periodically and cleaned. The optical sensors get covered in crud just like the old mice roller sensors.

Using the 'pop off method' then.

It was a smart and simple design though.

You all love that game. 
It's not my thing, but you do you.
I've been messing with little boards like this
ESP32-LyraT-Mini V1.2 Getting Started Guide — Audio Development Framework documentation[^]
I worked over the 14th and part of yesterday getting what I thought was an ES8388 audio chip up and running. I got the code all in place, launched it, and nothing.
Scanned the I2C bus, and strangely I get two device addresses, neither of which is an ES8388 address.
I was so frustrated I put it down.
Today I look at my reference code. It has code for several boards, among them (I thought), my board, the LyraT Mini. But it has several revisions for the full sized LyrAT (which I also own)
I look at my board again, and it says 1.2 ... clearly they don't use semantic versioning on their hardware, because they made major breaking changes from what I think now was 1.0 code (due to the lack of version in the codebase). I've had other vendors audio boards that were worse, changing audio chips from build to build, same version, but it's as much a hassle here, just not *quite* as much of a minefield.
So I have all this code for an ES8388 and I'm hoping my LyraT 4.3 can run it, because it's the last one I have that might have that audio chip.
As far as the mini, I'm going to shelf it until I can deep dive Espressif's Audio Development Framework codebase for it, which is a multiple board and version supporting monster of a codebase. I'm feeling overwhelmed at the prospect.
All this for some blips and bleeps.
I haven't even ordered the board that wires to google voice services yet. I figured I'd mess with these first, but it turned out to be like pulling the dash off an old car someone did a hack job on, and then trying to find which wires go where to the point where you wish you could just replace everything. Except I can't, because I didn't build the boards. 
I'll figure it out eventually, but the joy is bleeding out of this pursuit pretty quickly. Fortunately it's not work, which has been going pretty well on my end, though the rest of my team can't say the same, so I feel kinda bad for the hardware guys. We had some successes over the past couple of days so I'm encouraged. I wish I had more to do right now though. My personal pursuits as above are going less well.
To err is human. Fortune favors the monsters.

Have been following your exploits, but I am curious (I may have missed it along the way).
Your developing/designing/building hardware/software for
Audio applications that
Manipulate or create audio from
synthetic electronic sources,
digital electronic sources (keyboards, guitars, ...)
analog to digital sources,
microphones,
...
?
excuse my ignorance as I am not familiar (other my ears)
with this area of technology development.

Ah so, got it.
hot wet garbage 
Great description. You do have a way with words.
Developing/modifying software for OTS hardware is a daunting task at best.
wish I could offer help, but outside my area of expertise.

And I find it damn right. I do not complain about it, but it is neither my thing. Your posts are sometimes very difficult for me to follow, but they do are a very welcomed "diversion"

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?
Help me to understand what I'm saying, and I'll explain it better to you
Rating helpful answers is nice, but saying thanks can be even nicer.

i spent much of yesterday trying to understand why a bit of C++ code would not compile . it turns out if an aliased type is replaced w/ the original non-aliased type as specified by the template declaration it compiles fine . sent a bug report to Microsoft .
