The Stovebolt Site Forums The Shop Area The Electrical Bay somthing new

I'm Working on a fuse box that will have 12V on one 1/2 and 6V on the other 1/2. And would like to know what you stovebolter thought and if you would buy something like that. No resisters no math just decide what you need to be 6V and what needs to be 12V.

Original smartass comment directed at original subject thread with phunny spelling is retracted.
As I said originally -I apologize. It was too hard to pass up.
Auto - consider your second job as stand-in moderator fulfilled.

I'm surprised you can patent a voltage reducer. How are you regulating the voltage on the 6 volt side?

Will it be clean enough to run a radio and provide enough current to power a heater fan?

Houston54,

Maybe it would be more considerate to 'delete post' than to apologize... and leave it! :rolleyes:

Stuart

I like it right where it is but thanks just the same.

Oldsub,
It has a filter on both sides and on the oscilloscope it is vary clean.
There are actually about 13 patent on it

Don’t you worry I will have many pictures for you

I lok fourward to it.

Okay that would mean it's clean enough to run an old six volt tube type radio.

How well regulated is it?

Does it put out enough power to run a heater motor?

What is it going to cost?

OldSub,
6V radio Yes one of my test loads is the 6V out of my truck it is cleaner then if you would put just a resister on it.

How dose it regulate? Well the basic is a zener but it is not that simple.

The prototype is set up so that you could have 200 AMPS going thru it but you are limited to your alternator.

Price I don’t know what it will be for sure but the currant price is looking like about $150 to $175 but I do not know until after I'm dun with UL.

Okay RBT I just wanted to hear enough detail to believe you know something of what you are doing. I don't need to know enough to try to duplicate your effort (as if I could).

How do you intend to market this device? How will the manufacturing be handled?

Oldsub

Well I plan on marketing it in classic car magazines and auto shows it will be small to start I have some venders already interested. Manufacturing well the casing will be out sourced by a plastics manufacture out of Gastonia, NC and the electronics and assembly will be dun in house I will add a sub deviation to me elc. RD firm.
If you wont to know about my back round I just received my PHD in elc. Engineering from the university of MN. I started out in the elc design industry doing testing for Medtronic’s 8 yr ago and started my own firm 3 yr ago.

If you could come up with one that has a booster in it (6v in, 6v and 12v out) that could be cool too.

I could do it with AC but you would need 2X the AMPS

Apparently Im missing something. Why would you even want something that could provide both voltage outputs? Why not one or the other? Its just simple to either go with 6 volt or go with 12 volt. No math is involved. All of my 6 volt equipment works wonderfully which is why I see no need to change any of it. Also upgrading to 12 volt is simple in itself. ???

yes if you whant to upgrade evrything

I think that's a fair question, but I also think there are some reasonable responses.

If you want to run a modern radio and enjoy the often better starting 12 volts gives you, this approach would let you do just those few things, and not worry about changing all the lights, heater and fuel guage.

The only reason I'd do this would be to get my fuel guage right and run an original radio while enjoying 12-volt starting and headlights.

But the truth is I'm not likely to do because a full conversion to 12 volts is likely to be cheaper and the advantages of running anything on 6 volts are not likely to change my mind.

I guess it seems kinda half assed to me. If your gonna change from 6 to 12 why not just change out the few things that are necessary.

I guess I would rather go with 1 system and have it regulated across the board without change. It just seems like over complicating an other wise simple task.

Just my thoughts.

1947RBT,

You would need more than 2X amps from 6 to 12 inversion unless you have 100% efficiency, however, items running off 12 volts only require 1/2 the current for the same wattage, so you're only out the efficiency loss.

The only reason I can see to have a split system is if one wanted to have an original look, but hidden 12 volt devices.

Well it's one thing to engineer a solution, its another to convince the market they want it.

I suspect the problem with this product is that not many people will be willing to pay more than the cost of a modern radio for a device that allows them to run the old radio and guages.

I find the engineering interesting. But making money requires understanding the market too.

Well one of the reason I put it out on some forums was to do some market research the funny thing is some forms are like this is the greatest thing and others are like why. I developed it because I don’t know how many times I have put a post working some one throe ohms law so they could use some 6V devises or iv seen cars with resisters soderd on to something well this all works but why bother with resister on lights and radios and just have something that will do the wok for you. I’m just doing market research.
