Hot Rods Will a 12V solenoid as my switch power my oogah horn if manually pulled?

I've been reading about solenoids and it sounds like they create current if you manual operate them.
Could I hook one to my oogah horn and send it a really wonky signal?

I already tried a 12v to 7.5 step down converter but signal too clean...

I this solenoid idea

 

Bueler? Anyone?

 

I'm not getting how you are manually operating it. What solenoid are you planning to use?

 

I think your confusing the term solenoid and relay. A solenoid for our purposes is generally used as a mechanical actuator to activate a latch for door poppers, trunk release or whatever.

A relay is an inline electrical switch used to take the load off a dash board switch for example. The fan switch on my new 32 project would get hot when you turned the fan on so I ran a hot wire from the starter terminal to the electric fan with a relay in line. That way the switch in the dash would trigger the relay to activate the fan and the dash switch wouldn't overheat anymore.

Of course you need to wire in a fuse so you don't burn anything up in case of a short.

Tons of info and diagrams online if you need them.

Unless of course I misunderstood the question.

 

I want to use a solenoid as a small generator to generate current to run my horn. Kind of like the old western movies with the dynamite spark generator

A solenoid is an electro-magnet, i.e. coil of wire held in place on a form. Attach voltage to the coil of wire and it will **** a piece of steel into itself. That steel need not be magnetized. And the distance moved is quite short. If your Oooga horn needs a lever moved then the answer is yes, the solenoid will pull the handle of the horn when voltage it applied to the coil.

Are you thinking of a generator, rotary or linear, whereby a magnetized steel moved inside the coil will create electricity. If so, the answer is no it won't power anything except to move the needle on your meter or maybe give you a small shock.

I'd like to hear more about step down converters and clean signals. What's that all about? We could all use a clean signal.

 

Yep.. basically what I want is a push pull switch that will generate the current from me pulling it like a hand crank generator. Step down converter check it out.

They also make a 6v one

OK, now you have us really confused. The link you sent is for a 12volt to7.5VDC voltage regulator. Are you trying to run a 6 volt horn on 12 volts? If you are, you have to know how much current it will draw on 6 volts, and size your regulatior or dropping resistor from there. If your horn draws more than 3 amps (it probably will), this converter will shut down (that's the over- current bit kicking in ). We need more information.

 

12volt horn run off the 7.5v 3amp power supply

I'm running a 12v horn on the 7.5V 3 amp power supply. It overheated when I added the lamp into the circuit. But other than that it seems to work fine now that's it's cooled down.

? wot? ...... read it again its still a big ?? but to answer the initial question , no , BUT , sorta sounds like you want to vary voltage to the horn to make weird arssed noises?

 

For years, at least up through 1948, the real Ford starter solenoid had a push ****on on the bottom. 12 volts doesn't seem to bother one so I'm sure if it could handle 500 cranking amps for a starter it could power an Ooga horn. Remember these solenoids were activated by GROUNDING.

 

The lamp? What lamp?And what overheated? the horn?

 

Is this what you mean, only pulling the toggle lever to actuate the horn? What about a small central locking solenoid if you really want to go down that road? Cheap and readily available.

Small and light but would it have enough power to pull all the way out against the spring tension?

 

A solenoid does not generate power, it p***es power from on point to another like a relay.

 

The light bulb was in the circuit to try and reduce The amperage and to create a signal that started weak and then built up. My thought was that as the filament warmed up, the impedance would decrease.

But what happened was that when I hooked up the lightbulb either the lightbulb worked in the horn did not or the step down power converter overheated and stopped working.

I buy mine at ACME supply,they have a lot of dinamite on sale right now.
Use code #fuktharoadrunner for a discount¡

 

Why all this work? If its a 12 volt horn just send it 12 volts. I hate electrical ****, keep it simple and it works better.

Are you possibly trying to make a standard horn do an oogah sound?

 

If I understand correctly.
You have a 6 volt aahooga and it isn't providing a slow varied sound with 12 volts.
Get yourself a 6 volt battery and dedicate it just for your horn. Easy fix no headaches.

 

Yes, you have to move a magnet through a coil to make voltage and it won't provide enough current to power a 6 volt horn. Those old style detonators had a magneto turned by a rack and pinion gear.

No. I have a 12. Volt horn and it sounds awful on 12 volts.
I only get a the ooo sound and it's very harsh at that.
I got a step down converter that sends it 7.5 volts 3 amps.
But I still only the oo-gah sound
I want the " ahh "part of the ahh-oo-gah sound

Basically what I'm asking now is if there is a pull switch that generates it D.C. Voltage on its own by pulling it. Like a looney toons dynamite switch does.

The 12 volt Harbor freight oogah horn sounds like crud on 12volts. Sounds good on 7.5, 1 amp

This thread is repleat with strange understandings. I.e. tungsten lamps actually have low cold impedance which increases as it get hotter/brighter with applied power. Hence the lamps high inrush current upon power up. Then there is using an unreliable 3A voltage regulator to reduce power to a 10A device which itself speaks volumes. As does trying to create power out of nothing. Or pulling/pushing a solenoid to create power. Most know a 'starter solenoid' is a misnomer ... it is actually a relay made from attaching a solenoid to a set of high current contacts. Solenoids do not produce power. God give me the will to avoid this thread cuz while I try to help legitimate problems, I don't know whether to laugh or cry here.

 

No.

 

well **** ........................................how do I apply to get my 5 minutes back?

 

...and I thought it was only me.

 

Sorry I was replying using the app on my phone and couldn't see that the answer lies right here.
Pulling the solenoid piston will not generate enough juice to honk my horn.

is there such a thing that will?

 

My goodness. You're trying to get a cheap horn to sound good by crazy ideas that won't work.

Get a proper horn and ditch the cheapo.

It will never sound good. And all this effort is wasted on a $7 horn.

Is this what you're talking about?



If so, there's a small generator inside the box. The generator has a shaft that has to spin to make electricity. The shaft has a flywheel on it. The flywheel has teeth. The plunger also has teeth which push on the flywheel teeth to make the generator spin.

There is no device that generates electricity simply by pushing up or down on it. They all have to spin. The reason the dynamite plunger box looks like it's producing electricity by pushing down is that it is actually changing the up-down motion into a spinning motion.

Now you have to consider portions. You would have to pump the handle like a mad man to make enough electricity to honk your horn.

Sorry, GENERATING electricity by pushing a plunger down is a bad idea. Especially when you have an easy source of electricity right at your car's battery.

Are you wanting to make a SWITCH that looks like a dynamite plunger, for novelty purposes?

If so, just make a wooden box with a plunger that goes through a hole in the top and pushes on a horn ****on mounted in the bottom of the box.

I could be wrong, but I think you may be using the word,"generator" when you mean,"switch."
