STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

How useful will a PC based Oscilloscope using a sound card be for the task at hand, http://www.micahcarrick.com/06-06-2006/pc-sound-card-oscilloscope-linux.html

A buffer hardware circuit could be used to buffer the probe similar to a true oscilloscope and protect the PC's Line In from excessive voltages.  Would I need the buffer hardware circuit, or could I get by with just protecting the PC Line In with a Voltage Divider.

I don't have the money to buy the real thing.  I know being cheap isn't the best thing, but it has to be better than nothing and doing it totally blind.  Any thoughts?

Thanks,

GB

The more of the files you verify were last modified in early (February) 2009 the better.  You have no idea how much I appreciate it!

Thanks so much!!!! It would mean the world to me, as this is at least some evidence that in February 2009 I uploaded my designs based on a technique of using a toroid as a magnetic switch. I have always planned on making my designs open-source, but always planned on starting a business manufacturing & selling excess energy devices to people who don't want to build their own, that is *after* such technology is proven.

Also, IMO I'm not the 1st to re-invent this technique, but I would like as much evidence as possible in case Steorn ever decides to sue me. btw, I would never in a million years sue Steorn! Nor would I have grounds to sue them.

btw, the reason for the request is that google says they will soon move (and convert) my entire googlepages site to another server and completely different system, so the file date stamps will be no more. Thus I'll no longer have proof that I upload the above files in Feb. 2009. Some may say that's not proof in court, but I would definitely not be so quick to say that.

Just make sure you're aware that method cannot measure *DC*. It's only good for AC. Not sure the lowest frequency.

Completely away? 1 inch I would say.
Anyway, I haven't got a LCR meter yet, so I can prove my conclusion to my observation is correct. Time will tell.

Yes, the magnet was moved as far away as possible. They showed the inductance change. You can see this at the end of the video #2 & start of video #3 in the Steorn 2nd Talks.

People need to know that measuring the inductance of square loop cores can vary by massive amounts. I now think the inductance meter came no where near flipping the cores domains, which meant it was seeing the cores permeability on the lower end. If true, then there are at least 2 layers. Probably not that many layers since there's not enough room unless they use thinner wire.

If I had to take a wild guesstimate, I'd say the scope slope of my cores is ~~ 10 times more than Steorn's. Given a perfect system, inductance increases at turns^2. So today I might add two more layers for a total of 3 layers, thus increasing the inductance ~ 9 times.

My tiny orbo input power was 130mW @ ~ 4000 rpm. After some thought, that figure could come down by a thousand times or more, IMO. Time will tell.

I did a little more research on this and it doesn't look like a good idea after all.  Sound card inputs are AC and can't measure DC like you said.  The frequency thing is an issue also.  Looks like eBay is my only option.  Thanks for your input.
