AIUI it's because the PIR has the radio transmitter and there no wire
to hook into.

Not likely. Salt does not have the density of lead so no matter how fast it travels it doesn't penetrate anywhere near as deep. Plus they load the cartridges lightly, precisely so they don't kill.

Very comforting if you get blinded, of course.

Same comfort level as one would have stumbling over a root and taking
a stick to the eye.

The rocks that hit me barely broke the skin. I flicked them away with
a finger. Unfortunately I could not flick away the awful burn of salt
in a fresh wound.

I doubt that a rock with that little energy could do permanent damage
to an eye.

When I was about 6, I had a large wheel tricycle. I decided to try
riding it down some outside stairs. The result was as expected. I
crashed into my parents' car. I had a plastic straw in my mouth
positioned outside my teeth. That straw poked a nice clean hole
through the back of my mouth and out the back of my neck, incredibly
hitting nothing that mattered.

After a trip to the ER and a couple of stitches, I learned several
lessons. Don't try to ride down stairs on a tricycle (wait a few
years and do it on a motocross bike Don't run with a straw in
your mouth. Cars of that vintage are TOUGH. neither a dent nor a
scratch in the paint.

If he were more forthcoming about himself and his application, even a motion-detector might pass muster. But as things are, no way, oh-jay.

I'm assuming, perhaps wrongly, that the useful options for "door state"
must be either Fully or partially Open OR Closed? A microswitch
fixed carefully at the Closed position would therefore determine one of
those two states.

Or is there perhaps another state, Closed and Locked, that must be
determined?

Anyone ever heard of a device that can create a buzz the same way
human lips do when playing a brass instrument? I.e. a membrane that
oscillates but the propagation of the flapping/buzzing/vibrating is

The device would need to be adjustable - buzz at various pitches.

Does anything like this exist?

You could try a small voice coil speaker driven with a square wave, but
I expect that the acoustic source impedance would be pretty
different--back pressure from the instrument will modify the speaker's
response a lot more than it would a pair of lips.

That is, it isn't enough to make the same sound--you have to match the
acoustic characteristics well enough.

maybe mould some silicone rubber lips, if the project is still live. You could probably buy them, but you might not appreciate the pose

It's been a year...

It sounds a lot like he's asking for a car horn - he doesn't say that
he wants the frequency electronically asjustable, so an electromechanical
buzzer (with an adjustment screw) driving a diaphragm fits that spec.

something interesting might be possible usign a 2 coil speaker allowing
feedback for the system to adjust to the resonance of the
instrument.

It's not!

This suspiciousness has gone too far for my liking. Nat West refused to
open a bank account for me cos they think I'm a money lauderer; likewise
two German banks before that. The tax people keep asking for evidence of
this and evidence of that and clearly have me down as a tax-dodger. And
only today because I wanted to buy 2 packets of paracetamol I had to be
grilled by the pharmacist as to why I wanted the second packet! World's
gone mad. You know what it is: we haven't had a major war in decades and
everyone has lost their sense of perspective and proportion.

Very few people are good at soldering. The defense companies require extensive training and certifications in order to touch any equipment that is customer category. Most engineers are adequate, at best. And that is the way it should be

I think in my day I could solder "adquately" as you say. It was when I met people who do it 8 hours a day 5 days a week that I realized my soldering was very poor by comparison.

These days it is mostly done by machines and the quality depends on the temperature profile and the design of the pads. Again, that's not my part of the job so I'm no expert, but I'm not sure many people responsible for the soldering are "experts" either. They get the job done though.

There is no shame in liquid solder flux.

About $6 a bottle, which will probably go bad before you use it up.
