    555 Signal Generator/Power Stepper

    I see. What you want to use 555 for?
    Ok, you asked I'm working on a CMOS 555 based frequency/pulse-width dynamically controlled power stepper. The kind of stepped power one might drive a motor with or control the heater on a soldering iron.

    Application-wise, Producing maximum sensory feedback about radiant production/recovery - wadititisanwaditshudbe It's exclusively for testing and measuring different coil designs. Spark-gaps, as previously mentioned, too, as well as EVGray tube type devices. So got to say it's more than a signal generator because I intend to pulse various levels of power into the target device. I'll also be aiming to scale down and minimize any HV heavy going on, being primarily concerned with constructing a safe, portable, and informative testing environment.

    I'll always be driving a power switch with the 555 signal. The Stingo setup may just be the sharpest way to do the switching...capiche?

      I see. Good luck .

      Be carefull when playing with spark, I kill two 555 and 5 computer fan when I get spark at primary. Watch out the heat too, it can melt transistor core.

        In the recent thread about don smith, there was a link to a long document that had a 555 timer circuit near the end of it. The circuit is for driving a spark gap to resonate a tesla coil. I replicated a low voltage version of it and took some scope shots.

        Sorry for the video being sideways.

        The stingo impulses have nicer slopes, but this is meant as input to a spark gap which produces the nice steep slope.

          Thanks for the video and scope shots, 7imix. Very interesting!

          What's different about your circuit. 3V? What coil?

          Thanks, that's really useful data.

          Why have the single toroid coil paired with a car ignition coil? Is the single coil stingo feeding the one with the car coil in a staged configuration?

          From what I recall Peter Lindemann once mention that bifilar coil will make the coil collapse current to flow to each other coil. He said that for radiant recovery, bifilar may not be optimal.
          Although I haven't experimented with them enough to measure their characteristics, I think that a bifilar coil's type of capacitance may help preserve/pass on radiant energy.

            That just an actuall implementation, something that I already have. It is not that important. But what you mention also happen, the circuit have effect on each other, that the other coil may still works even if you pull some of its component ....

            Just like what in front of me now, I add relay based oscillator to the FWBR merger, the relay sing too .

            Well, just try it. I found that sometimes implementation defies theory. Stingo teach me that . So I am not that surprise if I am wrong now . But please compare bifilar and single filar having same impedance, core and wound.

              Now the 3V test bed gets interesting because the output does not overwhelm the scope or 1x probes :



              As I turn the knob more to the right, duty cycle %, decreases. The frequency declines in the middle. Then the frequency starts to rise again, and I hit a new sweet spot around the last third of the knob where the frequency peaks again at around 2.6kHz :



              The duty cycle drops to 4.2% :

              post note: One important measurement I left out was output current...only way to really tell what the total power output of the radiant spikes were.

                Cool, dude, thanks for the test and scope shots.

                I have been working on something else for a bit, but hopefully I'll get back to testing stingo soon.

                  Very interesting result Godfrey .

                  But add at least 100 ohm between the PNP and potentiometer to prevent you from burning up the PNP.

                  It is interesting that you get two sweet spot. It also show different wave form. one with bouncing, other don't.

                  You don't get oscillation with secondary being shorted? try reconnect the power. Don't short it while running.

                  I use TIP2955, TIP32C and 2SB507. I prefer the cheapest TIP32C though. I don't think I can notice the difference.

                    I have noticed that sometimes I need to give the circuit a kick by disconnecting the battery and reconnecting it. The transient spike generated by closing the circuit seems to start the oscillation.

                      Yes.

                      BTW, I get blackout again last night and try both parallel and series. It seems both have similar brightness. So I goes power out is the same on any configuration. High voltage low current while in series has brightness equal to low voltage high current in parallel. I don't measure input power though.

                        I've been putting together a new higher voltage Stingo using a TIP2955/TIP3055 pair. I got it working with a toroid coil at 6V and 12V and one of my ignition coils at 12V. They both light a neon bulb across the output and I got the ignition coil secondary dimly lighting a florescent bulb. I'll be posting pics of my setup, scope shots and current measurements. I'm very hesitant to subject my little scope with the 1x probe to the output. I'm ordering a 10x probe that will be good for up to 300V, and gathering ideas on how to make my own HV probe.

                        Gee guys, I'm really scratching my head over this one. Not only my little 3V transformer, but the toroid coil is acting this way. I've got a switch which I've flicked off and on several times to try and get it working, with a shorted secondary. I can even start and stop the oscillator by disconnecting and connecting the secondary short, while the circuit is on!

                        Running a load on the secondary of the small transformer and the car coil worked. I haven't tried shorting the secondary on the car ignition coil or running a load on the secondary of the toroid coil yet. Will investigate further.

                          great . I get brighter neon with my transformer than my car coil.

                          Mine reach 1000V on analog, about 800 on digital multimeter. Maybe you need higher.

                          Do you test it with full circuit or the simple one? Now that you mention it, I seem to test it with the simple version. The one with neon load at primary use my hand as resistor.

                            Do you mean the simple circuit failed when you shorted the secondary too?

                              Here's the post I built my first sparker from.

                              http://www.energeticforum.com/renewa...html#post99691

                              I've built a few of these, sometimes I use a 1000 ohm resistor and sometimes I use a 100 ohm.

                              Thanks for the cool info, godfrey. I've got some fun stuff to share, I'll post in the stepper motor thread.

                                If your coil is not oil filled, maybe you can fill it with oil.

That and the inductive energy given off by the coil gave me a positive feeling, almost light-headed.
                                Thanks for the info. I never know such different exist . All I know that other people complain headache when doing experiment with car coil. I guess different way of switching can make a difference.

                                Did you connect the common terminal to battery positive?

                                I think it depend on the coil resonant frequency. If the coil have iron core, it would prefer low frequency.

                                Yes.

                                No. To be sure I retry it again with complete circuit today. With car coil the neon bulb is brighter when the secondary is shorted. and I recall that with analog volt meter my air core transformer give the opposite result, less output voltage with shorted secondary. I think the core type can change result..
