Whoever cleans up after me would be best served with a 5 gallon can of 
gasoline and a match. There are several books about 'Swedish death 
cleaning'. Supposedly the Swedes have a word for getting rid of all your 
junk before dying.

Path of least resistance. There are a lot of chassis available in the $20 
range. They're a couple of pieces of plexiglas, standoffs, encoders and 
other hardware. Most include TT gearbox motors.

I'd previously built a 3 wheel chassis with converted R/C servos but these 
seemed a little more, um, finished looking. A problem with 4WD is the 
motors don't have quite enough torque to skid steer for tight turns. You 
need to reverse the drive on one side rather than just bulling around.

I'm pretty sure I read it about 30 years ago but I'm reading Neal 
Stephenson's 'Zodiac'. The protagonist goes to a hardware store to find 
some way to block the ports in a chemical plants underwater diffuser. 

He notes that young clerks try to be helpful while the older ones let you 
wander around without bothering you knowing that almost nothing that's 
bought in a hardware store is put to its intended use. I had to laugh 
having been there too many times over the years.

Yup.

The R4? I've been working with the Pico W but the Arduino format is 
attractive. I like the USB C  rather than Micro USB. My eyes aren't what 
they were 50 years ago. That's the mice thing about the original Uno -- 
you can't confuse USB B with anything as you search through the cable 
collection.

As everyone moves to Arm M cores it's a little less like the wild west. I 
never worked with the PICs, only the AVRs. Back then I was working with 
assembly and the AVRs were more like the Intel devices I was familiar 
with.

When they built the new library they incorporated a maker space rather 
than a few things stuffed into a meeting room. I don't think it's a formal 
class but someone is available Saturdays to help with Arduino projects.
