An alternative Bedini circuit

[lanenal]

Anyway, I redone the circuit with a linux graph program called Dia. See the new graph below and enjoy!

There are a few programs out the which are free and allow you to create circuit diagrams, I understand that they also allow you to test them, but I'm not sure as to their prices.  I am limited to Linux software, and thus only have access to a few programs, which I can assure you, I haven't got any real working knowledge of at the moment.

Some of these programs are:  klogic, kicad, ktechlab, geda, and Berkley's SPICE; no links, you'll have to search for these.  I would recommend geda and SPICE over the others.

Additionally there's a program called VYM ( view your mind ) which has nothing to do with circuit boards but could help with concept analysis.

Here is my second version. Comments welcome!

Scematic from second version cant work!
No DC current cant flow to collector.
(so also not AC)

Hi Pese,

If you take a second look again on the circuit then I think it can work as follows:

The magnet coming to the coils' core induces current in L2 (because the induced voltage from L2 sees a closed circuit via R1, R2 and base-emitter of Q1)  so base current can switch on the transistor like in normal Bedini circuit,  the transistor now connects the battery B1 to L1, the collector current can flow through L1 directly from B1, ok?
When the magnet is moving away, transistor switches off, flyback pulse from L1 is directed to B2 battery via diodes D3 and D1,  ok?

Diodes D2 and D4 are guiding the negative half-waves of the moving magnets'  induced energy into B2, the positive half-waves trigger the transistor base-emitter.

What do you think?

I agree with Gyula, just one correction: the trigger coil closes the transistor when the magnet leaves the core.
See this youtube video: http://www.youtube.com/watch?v=yi7cmUpMdX8

Another thing that I am not quite sure with: when flyback pulse from L1 is directed to B2 battery via diodes D3 and D1, there is another possible path via D2 (but is that really possible? I don't know yet).

Yes i understand your idea, but it will not work.
Simply say´d:
The Transistor first become not and Voltage to start.
If the circuit comes - with some triks- to oszillate,
and old this supply current over this CAP (that separate the DC to flow)
than THIS Cap charges up to an voltage, that the Transistor becomes no

more supply current to work. Pls try it...
I have done my life so mutch unusal transistor circuits,
testequipments and used unusal functions of semiconductors.
So most schematics, i must not more "try to see".
I have also "invented" that device that "Popular Electronics" -named-

NEGISTOR .
I have TISONE published that years before in an european electronic news.

- But now over 40 years ago... No more mutch value. It was used... but

nobody ave understand, te cause and function that this work.

Your ideas to find simply schematic transistors-circuits , instead of

IC´s . 
i find very good, also to understand the electronics.
