Re: Technology Backfire?

It's amazing that the old cars (pre-any computer control) could sit for over a month and still start. Even my old 1985 Caprice Estate Wagon with "computer controlled carburetor" (not really computer, I think it was logic controlled via feedback from the O2 sensor) could go over a month before showin...

Re: Technology Backfire?

Out of curiosity, what's the current draw when the car is turned off just sitting without anyone in it? Even with a modest draw in order to keep certain systems alive, which incidentally should be in power saving mode individually, the battery should last for quite a long time - definitely more then...

Re: surge voltages

That was my sneaky way of calling out the spam. I recognized the type of link even before I checked it out. (Yep, same type!) Well, at least it started a conversation! (We could keep this one and get rid of the OP's 2nd reply. Could still be useful.) And yeah, shinny paper is horrible in most cases....

Re: Cross Page Posting

Posting the same thing in multiple places, ie, this forum, other tech forums, places like Instructables, different groups on Facebook, well, you get the idea.

Re: Television Conundrum.......

If the pic tube is going, even old time gamers won't want it. As tempting as it may be to fix it, it's at EOL.

Do you have hazardous household waste / electronics disposal day in your neck of the woods? We have them, like, twice a year where I live. Maybe hold on til then?

Re: surge voltages

It's been Brick Wall since sometime in the 90's when I first read about them in Popular Electronics.

And it may cost more, but you, your children, grandchildren and maybe even great-grandchildren will have it. Try that with a regular surge supressor.

Re: surge voltages

Crowbar circuit, MOV, power strip surge supressor, or one of the ones I really want, Brick Wall. See http://www.Brickwall.com for details.

Re: ok,, New Project time,,,

Funny enough, I went in search of a more discrete version of a graph/VU driver and came up with the same one Janitor Tzap posted above (go to the base URL of the picture and search for "VU meter LM324") in order to customize the resistor chain to deal with the non-linear sensor. The quick way to get...

My first "Walkman" (generic unit) included its own FM Stereo cassette adapter that had little pin pads in the cassette and pins that stuck up out of the cassette well. It worked fairly well, except the contacts would get dirty quite easily. I may still have that in a box somewhere....

Re: ok,, New Project time,,,

i am about at my wits end on this.. Grrrrr i was doing some more testing,, the output maxes out at 4.08v at about 78% of full. anything beyond that is the same. there is no way to tweak the sensor as it snaps onto the dial face ( it's isolated from the tank. ) i think that will be my main obstacle ...

Re: Something Wrong with Coupling Capacitor

The role of a capacitor in the signal path is a complex one, but it can be most easily explained as the two roles of 1.) blocking DC and 2.) frequency control. DC blocking is just that, the capacitor prevents DC from passing through the signal chain. If DC were to get through, it would further bias ...
