And that takes some talent and dedication to achieve.

Post it in LTspice. There will be no problems with pasting
fonts back and forth, and we can see it run.

You cannot run an ASCCI file.

Yeah, come on Win, throw us plebs a bone here. What will it
cost you? 5 minutes of your time?

Are you being funny? If you want to see an ascii circuit
from google groups go the the little triangle in the (URH)
corner.. 'other message actions', and select 'show original'.

Hey, George, do me, and them, a favor and make an LTspice
schematic for them. I'm not a LTspice user, and I don't
know how to make one. I'm a serious user of Intusoft's
SPICE, with its superior schematic and graphing capability.
Whenever someone puts up an LTspice file, I have to copy
the relevant text part, and paste it into notepad, then
save it on my computer, but with an .asc extension, and
then go open it with LTspice, to see the drawing. Sheesh,
that's so much more work than simply looking at an ASCII
drawing. Whatever happened to all the dyed-in-the-wool
usenet denizens of old, and our beautiful ASCII schematic
drawings? I posted hundreds of them, back in the day.

Greetings, Gentlemen,

What's the simplest way of implementing this:

The 'quiescent voltage' (so to speak) of a car battery is typically
12.4V. With the engine running, however, this rises to 14V due to the
charging current from the alternator. How most reliably to sense when the
battery voltage exceeds 13V so a dashcam can be activated?


use 12V after the ignition switch, KL15 in DIN standard


Piggy back off the Fuel pump power. THe pump shuts off if the engine
is not running after x seconds if the ignition is on.

Tap the AUX power or the OBD-II port.

OBD-II only specifies an always on +12V battery, though I believe audi/vw puts ignition ON on one of the unused pins

Tap the CAN port. SMOP. ;-)

I wish. Not with modern cars. Trying to get behind the dash is a
nightmare and could even be seriously injurious if the airbags behind it
get accidentally triggered in the process!

If the sound system is removable that could be one path to the
accessory circuit.

I just tried it. Are you being funny? Because *nothing* you describe is
visible. NONE of it.

JL has the right idea, post a sketch or file somewhere.

There's a little dowward pointing triangle next to the reply button
which is just to the right of the time/date indication. that's "more
message actions" click that, then "show original".

Why do you want the dashcam to work only when the engine is running? If
you are parked listening to the radio, setting the satnav, or whatever
with the engine off, and somebody drives into you, wouldn't you want
that recorded?

It makes sense to only run the dashcam video when the car is active.

My dashcam plugs into one of the USB sockets on my car, and operates (as
others have suggested) when in "Aux" mode without the engine running. If
possible I suggest you do the same.

Most are battery powered and will trigger for 10s if there is any kind
of sudden acceleration event. You get the aftermath but not the lead up.

If the camera is running you get a 10s either side snippet locked when a
trigger event occurs. Exact behaviour depends on the model.

Yes, I'm sure that's right. But usenet is nothing more than a
server responding to the traffic, storing a recent portion, and
making it available to the public under some terms. Anyone can
have access to usenet through one of these servers, provided they
have log-on rights. Most of us, I suspect, use some 3rd party
service rather than their own ISP. I use newsguy.com, $80/year.
They provide classic usenet, ASCII text, no fooling around.

Since many years now you need a special tool to remove it, though. And
there are different tools depending on the car and sound system as
manufacturers seek to make it as difficult as possible for thieves. In
fact it's much easier and quicker for a thief to remove it using their
various nefarious techniques than it is for the legitimate owner with or
without the special tool and no experience.

I run Ubuntu. LTspice can run in Wine but I found some problems with XVII.

LTspice files are plain ASCII. You might be looking at an encrypted file.

The problem with $80/yr is when you forget to pay it and they shut off
access. I used to use paid services but always got hosed trying to
remember my login to pay for the service.

Yes, one can try to install Windows-only stuff inside Wine, but
that bring bloat and potential instability. For me ngspice works
reasonably well. Bringing LTspice and Wine is rather high price
to see circuits posted on the net...

LTspice files are plain ASCII. You might be looking at an encrypted file.

I wrote "encoded": the information is encoded as ASCII and I found
no explanation on the net what encoding is in use. It has _some_
superficial similarity to format of orignal Spice, but
organization seem to be quite different.

For known encoding I cold easily write convertor to other format,
but ATM LTspice files are useless to me.

** For several years I used "individual.net" which involved payment - but after moving up to Windows 7 found that no version of "Outlook Express" existed that was compatible.

A friend recommended "Thunderbird" which cannot access "individual.net" for some reason. So I went over to Google Groups.

Soon got used to it and it has a huge archive.

Yes, if nothing changes. I lost my card and was issued a new one with a
different number, so I couldn't even find my old news service to give them
the new number. My email also changed, so if they tried to contact me it
bounced.

It's a private project by Wolfgang M. Weyand in Bad Homburg, just outside
Frankfurt. You can send donations via Paypal. It apparently has been
running for many years.

It had a brief glitch several weeks ago but that was fixed in hours. Other
than that, no problems.
