Bedini Transistor Problem

[earthbound0729]

Thank you citfta for these recommendations.

I will try these later today and get back with you this evening.

One other thing I noted when doing a continuity check with the CS5027 transistor and that is the collector pin is connected to the backing plate and therefore could be grounded easily. Since I'm not an electrically trained person I don't know about these things, just merely making a note. The reason I see this as important is because the positive from the battery runs through here via the Main coil and because this backing plate is often in contact with a heat sink.

.....This is consistent with what I know of how the Bedini Circuit works; The Magnet moving towards (or away) from
the trigger coil is what drives the transistor closer to being fully on. This is a magnetic mirror where the coil reflects
what the magnet looks like to the coil back to it in reverse polarity. Pushing or pulling depending on the polarity from
versus to. So that when the magnet is closest to the coil the transistor is most fully on.

To have it any other way would be to inefficient. You would be wasting energy turning the coil on when the magnet
is very far from the coil. The Bedini circuit is inherently efficient.

Change your 12V light experiment around, the bulb should be connect to the power supply plus terminal,
the other side of the bulb to the transistor collector and connect the emitter to the supply minus terminal.

Now if you touch the transistor base to the PS plus terminal the bulb should begin to light. If you use a low
value of resistor in series with base like 10 Ohms the bulb should still light, but a high value like 10KOhms
it won't. If you happen to have a current range DVM, you could validate the transistor transfer equation
above.   

In trying to understand your info I seem to see this:

I looked over the entire Bedini schematic and can now see clearly why MY setup is wrong. My 12 volt light bulb, even though connected properly, will continuously be lit simply because I am connecting the bulb straight to the positive and negative sides of the battery at the same time. I am not really going through the transistor circuit because I have bypassed it essentially.

It would seem that by using the higher voltage Neon as directed it would prevent the passage of that 12 volt energy through it, maybe acting as a resistor, and force the 12 volt energy to be directed through the transistor as intended when the base is energized by the Trigger coil and thereby activating the pathway from the collector to the emitter..

Any comments? I will definitely try this tonight after I get home and get back to the forum with my success.

Additionally, I will put the 12 volt light bulb downstream on the emitter side and keep the Neon in the crossover state as mentioned last post. At least that way I will able to see the results of the energy going through the trasnsistor when the base actually energizes it.

OK citfta. WE have contact. Hooray!

Now to share some data with the energizer spinning.
Voltages:
  a. Through the base - 1.56 volts without a resistor. Using the 470 ohm resistor. No go.
  b. Collector to ground- 9.10 volts
  c. Emitter to ground - ~200 mv

The neon never came on that I could see. I would have thought I would have some light pulsating based on expected values from the Main coil field collapse.
I heatsinked the transistor and it got very warm.

Your requested values. Will be very close as above.

Emitter to Collector--8.95
Base to Emitter - 1.76 - 1.805

I am not using caps or a charge battery yet off the charge circuit.

Looking forward to the next class citfta.
