Replaced the electroluminescent  panel as it was not doing well at all after over 10yrs.  Took a broken 7in 12v monitor and it had a led back light setup that was the perfect thickness to fit. So I cut all the plexi and diffuser panels for length and width and wired it in and it is better than when it was new. So happy.

This was and still may be one of the best car cd radios ever made. Pioneer said it had 112db sig to noise ratio on cd, but when car audio magazine tested it, they found it was vastly under rated and it was actually 134db sig to noise ratio. Has everything one might want in a radio. 3 way crossover for subs, mids and tweets to be powered by their own amps. Up to 24db per ocatave for the mids and tweet rca outputs and up to 36db crossover for the subs. Time alignment for each  speaker in the system, RDS digital radio info, they didnt even have the RDS in place yet at the time. Pulls in traffic and emergency info. All sorts of goodies.

Im a happy Mags  ;D ;D ;D ;D

Thanks for the videos. The older ones are gems. You are a qualified em expert. I wish you are my next door neighbor.

Thanks.  I wasnt even going to do vids on this. After I got to the point of putting it together I thought it would be a cool tidbit to show.  The eletroluminescent back light element was pretty thin. Was very lucky to be able to use that led stuff from the non working 7in monitor to do the job.  Salvaged parts that the thickness was key for it to fit and work for me and every time i look at it working I an ecstatic. Technology of using leds for lcd back light has only been in recent years and Im glad it came to be. The radio came out in 1998. Id put it up against any radio out there today. No parts available except for the ribbon cable for the swing open face plate that is advertised on ebay all the time.

Still looking for free energy? Magnetic vortex?

Or quit dreaming already?

Nah, I havnt quit. Just some time for me and getting my radio working right. I dont follow the vortex stuff.  Havnt seen anyone make Ou from it yet. You?

Thanks for the reply.

OU is impossible. I am thinking at the atomic level. I think all em phenomena are caused by the repulsion force between free electrons.

If you put a strong magnet in each hand, the same pole face each other, feel the tension? Now wave 1 hand at 90 degrees to the tension, what do you feel the other hand? I feel an opposite vibration force. 

I think that is the true mechanism of em waves between antennas and air core transformers. The magnetic force is simply a circlar electric force carried by ferro matters or circling currents.

I know the key to the force is all based on f=Ke x q1q2/rr. But I can't put the math together yet. Forgot most learned ee theories.

I think earth magnetic field is caused by westward moving sunlight/ac current. Not yet figured out a way to proof it.

We need to know what exactly is energy first. energy is moving force carried by moving matters/charges. no matter moves without energy. therefore, no free energy.

If in fact there is westward moving electrical force in the atmosphere, produced by moving sunlight, causes earth magnetic field. We need to find a way to tap that current. Magnetic propulsion might be possible.

I dont believe the OU is impossible statement is valid universally.  Sure you can say it. But it is because you havnt seen nor experienced it.  You can stand by your statement, but it is only your opinion in my view, not a fact. Your statement should be corrected to "I dont believe OU is possible"

Magnetic propulsion?  Yeah I can dig that possibility.  But why would you believe that is possible, without seeing proof of it, yet you are solid on OU being impossible..

I have learned here over the years to use other peoples words to argue them successfully.

The magnetic propulsion is something I had worked on for a bit from ideas that are based on the homopolar motor/gen configurations.  Ring magnet and copper disk for example...

Spin the copper alone and current is generated. Spin the magnet alone, no current generated. Spin both together, current is generated.

So, if we spin both together and current is generated, is there a drag on the rotation when we apply a load to the output current?  If there is, what is it dragging against? Thus in that we should be able to accomplish magnetic propulsion. If there is no drag, then we have a lenzless system of which should be able to be used to accomplish OU.

Reread and think.

i believe ou is impossible if energy and momentum conservation are universal.

all things have a precise mechanism. science cannot explain the mechanism of magnetic force yet. why is moving current producing circling magnetic field? why is moving magnet producing a circling current? what exactly is a magnetic field? how it interacts with matter and charges?

about faradays paradox, spin magnet no radius direction current (any circling current on the disk? i find no videos yet, don't have the tools to test it), but if you move the magnet up and down, changing the distance to the copper disk, you should find clockwise and counterclockwise ac current on the disk, not radius direction current. you can measure the voltage between any two points on the outer ring of the disk. my prediction anyways. based on my belief of magnet carries circling electric force produced by atoms arranged into positive next to negative patterns. normal matters are formed by neutral atoms next to neutral atoms.

a magnetic field is a circling electric field. if that is true, may explain many em phenomena. Thanks for the discussing.

So that is what you believe in. Why? Any proofs?

can't prove yet. just my theory. based on some facts.

such as moving charges in a magnetic field change direction without an electric field at work.

my idea of magnetic propulsion is pushing/compressing earth magnetic field/current is the air. i think if such propulsion is working, it has to produce air flow to get thrust.

can you test if the copper disk produces circling current? spin the magnet or change the distance. cut a gap from the center to the edge of the disk, measure the voltage and current?

can i move to your next door? we get stoned and do tests all day long?

I had a theory a few years back..  I think the electrons are the source of magnetic fields. I think this is why electrons when broken away from their bonds move in particular directions to moving magnetic fields.

I cannot spend the time here to re explain that. Its here in this site somewhere I think on a couple threads.

my idea is similar to yours.

i am sure electron plays a big role in magnetism. i am also sure electrons are not spinning or circling in atoms. they can only move on the surface of atom ball.

a ferro material near a current, electrons in the atoms will move against the current, therefore atoms will line up as +_+_+_ direction within the matter/magnet.

a circular current in the coil will make iron core atoms arrange into such pattern all the way through, on the pole plane, concentric circles +_+_+_ atom formation.

too bad i don't have the tools to test.

a compass, atoms are arranged as +_+_+_circle along the length, therefore it will line up at 90 degrees with a nearby current.

earth has no magnetic field, has circling current. therefore compass line up 90 degrees to the earth spin direction.

force is invisible, but we can feel/measure it. forces are always there as long as matters/charges exist.

look the universe from an atom. electrons are float on the surface of atom ball.

image positive charge is a ball shape single north pole, negative charge is a ball shape single south pole.

a big/strong north pole will be surrounded by many tiny neodymium south poles, form an atom ball, iron south poles float on that atom ball as electrons. 

maybe that's the true structure of matter. assume that is true, follow the f=Ke x q1q2/rr fact, too see the world and everything.
