Bedini replication in Germany

[albert]

Hello friends,

I would like to mention an amazing site with scans of old electricity books. I am trying to go back to the source to get a better understanding of what we are dealing with in the Bedini and other motors.

If you put in a search for "induction coils" or "wireless" you will find old books on electromagnetic induction, the famous R?hmkorff coil and the like. Lots of drawings and great information to find there. Perfect scans, and you can look thru the books before downloading them when you click on the preview on the left side of the page.

My own interest in this field of high voltages started when my father bought a "medical" device in the 70s that turned out to be a Tesla transformer. I was greatly intrigued by the effect of lamps lighting in my hands and so on.

In 1992 I had the chance of a lifetime to find an ORIGINAL R?hmkorff machine on a flea market in Bordeaux, France. The machine looks exactly like the R?hmkorff Conrad roentgen used when he discovered the x rays. We have it here at the "DEUTSCHES MUSEUM" in Munich. The device still works but I use it only rarely because it is in  rather delicate shape. Paid 250 French Francs for it, about 70 to 80 dollars of today. the guys did not know what the thing was.

So this is why I always try to put myself into the mind of an engineer at Tesla's time. No semiconductors, no diodes, no vacuum tubes. Only spark induction machines, batteries very different from todays elements and eventually dynamo generators for the higher power.
When all the transistors were shorted once on my Bedini, I ran it with a mechanical interruptor made from two vibrating saw blades. It works just as well but most of  the radiant went up into the spark of the interruptor.
when I got back my new transistors I gave up on the mechanical switch because it produces lots of RF noise. But its an interesting thing to try.

Hello Ren,

I had to get the other isssue out of the way first, so now I'll try to answer your question.
Charging several bats with one 12 V/7aH bat in front does not work with my setup because I will exceed the c/20 discharge rate of the battery. At 12 Volts the system will draw up to 500 mA when I run it at its usual speed of 200 rpm.
By the way: Do you think the "sweet spot" is only when there is one pulse per magnet? I get anything from 3 to 10-15 pulses per magnet, depending on the voltage at the input. The scope shot shows the trigger signal with the pot turned back.

BTW are you in Australia, too? I think Australia is Joe Cell country. I would really see one of these things working....

   Off topic but just have to ask. What is a VB? Suspect its a beer right? I thought you mates drank Fosters. I like Wild Turkey 101proof chassed with a budwieser. Thats if I really want to tank it on.

@Thaelin,

VB or Victoria Bitter is a beer made by Carlton United Breweries, the makers of Fosters.

No-one drinks Fosters anymore in Australia, they make it now only for export. VB is better but doesn't travel as well.

VB is probably the worst beer sold here in Australia. As hans said, Fosters is only for export - nobody drinks it. Most places don't even sell it.
