Maybe your suggestion is actually relevant. Shouldn't we just put a PC
inside the ignition and steering system of a car?

Sure, and have Windows do your navigating. Great idea!

Most modern airplanes are fly-by-wire. How about cars? Are their
steeling wheels still using gears to directly control the wheels?

The power switch for computers are momentary, not latching so that
key switch isn't what you want.

Yeah, that's always a hoot where they just rip out the wiring and short
it out (must have arcing though). We used to have a model here where you
could just reach under the dash ans drop a coin across the back of the
ignition switch and away you went.

A taxicab by any chance?

I have to puzzle over troll feeders and why you waste everyone's
time replying to such obnoxious jerks. Are you lacking a person
with which to pleasantly correspond? Or do you troll feed just
to develop some minutia of an ego trip?

So does a car's engine stop completely when pulling the key out?

I don't drive. So pardon my question! But I like the turn-key mechanism,
as a power button for a PC.

Didn't know that "Mr." jerk-off was involved. I have him killfiled,
but not the subject, such as it is.

automobile ignition keys may hve several stop wich are stable
positions and usually one stop that operates the starter which is
spring-loaded


off , radio on, engine on, starter

but starter has a spring that return the key to the engine on position

if you use the starter contacts to mimic the start button that's
probably the best fit, or you could buy a key-switch with momentary
contacts.

eg: http://www.ebay.com/itm/2-NO-key-3-Position-Selector-Select-Switch-Momentary-/272331369003

they key will be smaller as it doesn't need to operate mechanical door
or steering locks, but the lock just needs a round hole cut in the
computer case. car parts are likely to need a special bracket.

When the key rotates from <engine on> to <radio on>, would the engine be
turned off instantly? I don't drive...

"I didn't write my question carefully. I just need the turn-key >mechanism
to replace the power button. "

Ok, I have stayed out of this because I thought it was stupid, but now I know for sure.

First of all, unless you weld the case together, anyone can find the two pins that need to be shorted momentarily to turn your normal PC on. And if you deny them physical access to the box itself they can get to the wiring anywhere and do it.

You can have a BIOS password to keep it from booting ANY OS, but usually, at least in the old days that could be thwarted by removing the CMOS battery.. Then you can have a password on the OS, which can be hard to break these days. The tricks we used on XP do not work anymore and neither do these apps you can download off the web.

One thing that does seem to work is loading Linux, by stick or CD, it can access the personal files unless they have been encrypted. Most people do not encrypt all their files. For one, there is no reason. someone can read my resume' ? So what ? Another reason is that it slows the whole system down. You buy a $3,000 gaming system and encrypt all files it will run like a $400 Walmart special or worse. Maybe like a 486.

Only, ONLY, if you know and use Linux can you bust the file protection of Windows, and that is only if it is not encrypted.

Anyway, you are climbing up the wrong tree. You put a key switch on a PC, I can beat it with a paperclip.

The End.

 

"Most Hollywood movies portrayed the turn-key mechanism as >superficial.
You always only needed to short 2 wires to start a car. "

Three. Before alternators four if you wanted to go far. Acually still four because to go far you have to activate the field coil on the alternator.

You find the hot (BATT) coming in, all the time you want to have it running that has to be connected to IGN which went to the point through the coil. There is another wire that enables the alternator or generator.

When I was a kid our car got stolen and the wires were cut. My Mother used to have to twist some of them together and then touch the "start" wire to them to be able to drive the car.

Fucking idiots want to steal a car, for like two bucks you could just plug your own ignition switch in and not go through all that hassle, but if thieves were smart it would be a different world. My cousin had the radio stolen out of his 1964 Olds 442. (was a 642 because he put some Edelbrock and Holley on it and it had six barrels) someone stole the radio out of it and he said "I would rather have taken the radio out ad given it to them" after he saw the damage they did. And he had guns. We are a car and gun type family. That cr would not do over 110 MPH, but it ripped the front bolts out of the front seats. (modified suspension, he knew what he was doing)

Anyway, I am a black sheep and know all about stealing, but use my powers for good...

My advice here is to lock up your OS and file system and just use the regular power button. If you put an ignition switch in there, which will obviously be before the 1970s when the column locks came out, anyone can just shave those wires and turn it on with a small screwdriver.

Think this through. you got two wires. No matter where you put that switch someone can get to the wires and once they are momentarily shorted your "security" is done been had.

If you need that kind of security I do not know what to tell you. Don't keep sensitive shit on your PC. I still design shit on paper.

And that is another thing, like right ow my ideas have alot of development to do, how does that compare to Hillary's emails and Snowden ? (he might have some but I doubt he has all)

What is so secret ? Mind you I will never say "If you have nothing to hide...." when it comes to the government and they all need executed over the fourth amendment, but this is not really like that.

Or is it ?

 

"Most modern airplanes are fly-by-wire. How about cars? Are their
steeling wheels still using gears to directly control the wheels? "

I would refuse to pilot or drive anything that was not directly mechanically controlled. I got 40 years in the electronics business and I do not trust it for shit like that. And that is why MIGs are better then the best planes the US has. And that includes the new F-35. Look it up.

 

"I have to puzzle over troll feeders and why you waste everyone's

It is a bunch of bullshit, but alot of people are doing it, even you. Even me once in a while.
