Perhaps it would be more productive to fix or improve the gate closing
mechanism, thus eliminating the need for a weather proof switch and
associated electronics? There is a wide variety of gate closing
mechanisms available, usually based on a linear or rotary spring
mechanism. Many can be retrofitted to an existing gate:

Oh...

Writing software, designing gate alarms, and in general, solving
problems are all easy if you don't worry about error conditions. Real
problem solving is more about dealing with oversights, errors,
anomalies, stupidity, and abuse, than about making it work. Whenever
approaching such things, I ask "What problem are you trying to solve?"
The answer often eliminates a wide assortment of obvious and usually
impulsive solutions.

If you can see the gate from the house, install a security camera and
DVR. I recommend the clear picture of an IP camera over the fuzzy
blurr of a composite video camera. Then you can see who or what
opened the gate. If the Mexican worker is clever, he'll probably
"accidentally" jam the gate open and defeat your scheme. If a camera
and DVR are too elaporate, a PIR motion sensor will detect the Mexican
directly.

However, if you must have a gate switch, the previously recommened
proximity sensors are probably good enough. A burglar alarm type reed
switch and magnet will also work if you keep them away from the metal
gate.

You keep adding requirements to the spec.

Often, it's useful to monitor the thing you want monitored.
Monitoring attendance is no guarantee that you actually get work.
Stated another way:
If you can't tell if the work was done, you're paying for work
you don't need.

Now i see (only since you pointed it out) the 0.60pF . On the basis of

have to make a rather sensitive capacitance
measurement device, as DVMs tend to imply the low value i calculated.

I got the catalog from the Ohmite site the same time this thread started.
Took a bit of digging.

Don't you have a proper LCR meter, or bridge? A DMM isn't really suitable
for measuring parasitic capacitance.

A "real" LCR meter, or impedance analyzer, is a must-have for any serious
work. You could use an old Q meter instead.

"Probe 1Gohm-3.jpg" shows the step still rising at about 1.8 microseconds,
where it goes off screen.

Risetime is the time from 10% to 90% *of the final steady value*. Risetime
is at least 1.2 microseconds, possibly more. It doesn't show the final

"Probe 1Gohm-3.jpg" doesn't contain enough information to calculate

And the gate is steel. Maybe the other way around, a coil whose
inductance changes with gate position?

A simple RF transceiver behind the gate at the right position. When the gate is open, it should block the RF signals. Detect it with Receiver Signal Strength Indicator (RSSI). As of the type of RF, 802.15.4 of course. Just hard code a 64 bit address. No BT pairing and WiFi DHCP headaches.

There was no claim that the gate was 'never' opened and you have no

Hi!

I am so "pissed" about RS-232/EIA-232.

After so many years with that "stupid vintage" serial communications
protocol, we still do not have autonegotiation (and auto-baud-detection)
built into the protocol definitions. Why not?

Why have nobody made a request-for-comment about that, then so many
people do not have to bother with a myriad of out-of-bound signals and
in-band signal (xon, xoff) manually.

It is simply incredibly, that after so many decades, you manually has to
find out, how to get it to work.

Please be inspired to release open and free RFC-definitions now, so that
"vintage" serial communication will work smoothly - and with backward
compatibility and of cause with auto "null-modem" functionality.

I am looking forward to, that all out-of-bound signals can automatically
be mapped by software by a series of signal pertubations and response
measurements.

I know I am very demanding, but it ought to be possible? At least the
software should detect and notify the user, that a null-modem cable
connection is required. But it is a bad compromise.

The communications world (and its users) would be much happier with a
full blown software solution.

Let us exterminate 232 jumper boxes. They are the ultimate time eating
stupid solution, that shows we have given up finding a better solution:

Instead we should have a 232 autonegotiation-box/cable, that can be
inserted between no-negotiation 232 equipped equipment.
