LED Heresy

Are you sure you don't put the LED backward? I think you should get brighter LED or even kill it if you reverse it

“I meant to do that!” – Peewee Herman I’m pretty sure that’s how I connected the LED, with its long anode leg to the positive rail, and cathode to the collector of the NPN transistor of your already bassackwards setup Why not break all the rules

Besides, any load is taking the reverse HV power spikes, which may pass right through an LED no matter what direction the bias is. Yes, it was very bright, much more so than simply powering it with 3V. Looking at it directly burned an image into my retina which lasted The LED is still alive and kicking, but I didn’t leave the circuit powered up for very long. Incidentally, that incandescent, yellowy-orange tint is normal. I plucked a big, clear looking one from my Radio Shack grab bag O’ LEDs and that’s just the color it happens to give off.

Mine reach 50V

Before it died? That’s pretty neat. Wonder if one could hold an ultra bright LED in its reversed, over-bright condition for long. That might be some kind of efficiency coup, potentially. Anyways, I think we ought to maintain an open mind as to how we expect different electrical components will react to radiant spikes. Keeping an inquiring eye on what actually happens, rather than presupposing. I’m still wondering when I’ll blow up an SLA battery with too much HV.

Complicated. Here is an example of combining two:

I like the two Stingos feeding one coil Looks good for a MOT.

Ignore the circuit, just put attention to the wire after the coil going to charged battery.

Still gonna have to chew a bit on this one

I’m also considering combining a 555 timer with a Stingo switch, like some of the other circuits you have posted up on ImageShack.

- Godfrey

post note: Yes, the reverse bias may be the only reason the LED lit brightly, not sure.

[Godfrey]

To 555 or not to 555 - that is the question.

I felt compelled to take it out of our private conversation and chew on this fat here for everybody to enjoy.

With 555 timer, it work better than normal 555 based one.

I always switch with a transistor or MOSFET You can actually see the 2N3055 sitting on my breadboard that I use with NE555's. It's slow enough to keep them alive.

But since it is so efficient, you might kill the 555 easily when playing with the circuit.

I would use a CMOS 555. Wouldn't that keep up with it?

Any 555 can be killed easily on radiant circuit because of its spike. I prefer stingo because it is more reliable.

I don't see any reason to use 555.

Show me a Stingo circuit that provides precise, dynamic control of frequency and pulse width and I'll agree with you.

DSO Nano Oscilloscope Issues

I have firmware version 2.02. I haven't tried actually saving any waveforms yet, I'll try it and let you know if it worked.

What clone do you have?

I’m really not sure how much the hardware actually differs from Seeed. The body and buttons differ somewhat. I’ve pretty much determined that any firmware out there for DSO Nanos should work. Here’s the outfit I got mine from, for what it’s worth:

General Eletronics-Tech

Now that I’ve gotten my firmware upgrading issues put to bed, the vendor does provide a satisfactory firmware upgrade that allows a 2GB Micro SD card to work, but it changes the UI to one identical with the Seeed DSO Nano. It’s both funny and a bit tragic, however, that the manual they include only covers the old IU which the upgrade removes.

As I delved into the problem more, Seeed representatives clearly stated in their tech support forum that problems occur using a 2GB SD card. It would seem from this upgrade, however, that the problem must be software based. I’ve found more recent firmware upgrades which use the UI conceived by a 3rd party developer name “Paul”. Many Seeed users prefer it over the native UI and I have to agree. But every one of these versions clobbers my 2GB card. I’ve got a 1GB card on order.

I’m an old hand at C/C++. I haven’t decided whether or not I want to get my hands dirty learning a new development environment and editing/recompiling the code for the firmware. It would seem to me that the data storage object library from the code that works with the 2GB card could probably replace the one with the UI I like, but time is precious, and I’m already up to my armpits in techie trivia over all this.

The main source of information and help on the DSO Nano still remains Seeed’s tech support forum at:

They’ve been maintaining an open source website with lots of goodies to download at:

Thanks for the idea about using a smaller transformer. I played around with this a bit and enjoyed it a lot. I will do some more detailed measurements and report about them tomorrow.

Looking forward to it!

I'm going to wind an air coil for it and see how high the frequency can go. I can't decide how to wind the coil yet... Bifilar pancake coil I think.

Shades of David Wagoner I’ve wanted to try a bifilar pancake air coil with an oscillator too. I’m still wondering what kind of back EMF, if any, would come out of it, since bifiler windings are often used to counteract BMF.

- Godfrey

[7imix]

Thanks for the information about the dso. I think I will have to figure out how to upgrade the firmware and install some third party software. I am also a programmer so I have fantasizes about how I want to change the ui. Hooray for open source!

I have a 2gb card too. I guess I should get a smaller one.

I’ve wanted to try a bifilar pancake air coil with an oscillator too. I’m still wondering what kind of back EMF, if any, would come out of it, since bifiler windings are often used to counteract BMF.

That is what I am interested in seeing. The bemf is not as interesting to me as driving the sharp sloped spikes into a tesla transformer with a termination. (probably a dead light bulb) Since the bifilar coil reduces back emf through self induction (I am assuming...) this setup should produce maximum dielectric induction, or displacement current. That is what I am most interested in researching.

Here's my 4th stingo build. It came out very nice and compact. I am using NTE392 and NTE393 transistors. On the right are the 500k and 10k pots. The 10k pot I used on this one is a very nice 10 turn pot. This makes fine tuning very nice. On the left are 2 pots for changing the voltage divider. I accidentally put a 8.8k pot instead of a 100k pot, so instead of tearing the thing apart to remove it I simply added the 100k pot in series with the 8.8k. This means I have a rough and fine adjustment on the voltage divider leg, which is nice.

The positive and negative battery connections are the wires sticking out of the left side, and the connections for the coil and the radiant recovery are on the right side.



This setup is pretty hard to tune since there are so many knobs, but once it is oscillating the tuning is very sensitive, which is nice.

Here's a side view showing the transistors under the board which is supporting all the pots.

[sucahyo]

Yeah you need to use brushed motors. Computer fans have a little board that actually generates ac to drive the motor. Try a cheap toy, like maybe some rc slot cars or something.

Brushless motor can use stingo too, Godfrey refer to my last post on stingo motor thread. I just post my recent experiment result that show stingo outperform standard bedini fan.

“I meant to do that!” – Peewee Herman I’m pretty sure that’s how I connected the LED, with its long anode leg to the positive rail, and cathode to the collector of the NPN transistor of your already bassackwards setup Why not break all the rules

Ok .

I still don't explore stingo use for LED lighting.

50V is measured output from 3V source.

I like the two Stingos feeding one coil Looks good for a MOT.

No, each stingo use one coil.

I don't see any reason to use 555.

Show me a Stingo circuit that provides precise, dynamic control of frequency and pulse width and I'll agree with you.

I don't need that. I currently have no use of "precise, dynamic control of frequency and pulse width". For charger stingo is more efficient. For spark maker stingo is more reliable. I don't have a scope so I won't be doing experiment on sensitive measurement.

But the primary reason is 555 is too fragile.

Cool . What is the spec of that transistor? Would it run on 1.5V battery?

[7imix]

Brushless motor can use stingo too, Godfrey refer to my last post on stingo motor thread. I just post my recent experiment result that show stingo outperform standard bedini fan.

Sure, but the bedini fan has been modified, right? It's not connected to the original board which takes DC and produces pulses. Having the stingo pulse the input to the PCB which is supposed to produce pulses isn't going to work, is what I meant. The stingo needs to pulse a coil, which it is doing when it is hooked up to a bedini fan. Am I right?

I haven't built a bedini fan yet, I am going to do that next so I can replicate your latest youtube video.

I still don't explore stingo use for LED lighting.

Godfrey inspired me to experiment with lower voltages, LEDs, and smaller transformers. I get similar results as when I did experiments with a joule thief, but I think this is even more efficient because the impulses are much shorter.

It's the equivalent of 2955/3055. I ran it today with 5v. I'll try with 1.5V.

[7imix]

Stingo provides very precise, dynamic control of frequency. Controlling pulse width doesn't matter -- from my Tesla research, it's my opinion it is always the case that the narrowest pulse width possible will be the most beneficial. Stingo simply provides the narrowest pulse width that it can, which is better than any other circuit I have seen out there so far.

If you can suggest a circuit that gives narrower pulses than the stingo, I'd like to replicate it. Thanks

[sucahyo]

Modified means we split the wire. from 3 terminal (1 common) to become 4 terminal. The controller is unused. Standard JT way require us to reverse half of the winding.

In stingo, the first half pulse the PNP, and the NPN drive the second half.


Notice that I have to switch the leg when changing from standard to stingo. You may not need to add another terminal.

I have been suspecting that but never sure. Thanks for the info .

Awsome! Thanks, 7imix.

Thanks Sucahyo. Very interesting!

A very practical application to explore, glad 7imix is looking into it – great LED vids, 7imix!

50V is measured output from 3V source.

Wow! What kind of coil got you these results?

No, each stingo use one coil.

Woops, missed that single coil on my first scan of it. Now it looks like a 2 stage step-up circuit, the first stingo feeding the second. I had been assuming you were combining the two in parallel. I’ll be analyzing further.

I don't need that. I currently have no use of "precise, dynamic control of frequency and pulse width". For charger stingo is more efficient. For spark maker stingo is more reliable. I don't have a scope so I won't be doing experiment on sensitive measurement.

Ok, good to know/understand about Stingo’s strengths for generating short pulses, which maximizes battery charging! Thanks.

However, I’m inclined to think that a specific frequency and pulse width changes the nature of the radiant energy being output. And so intend to develop a circuit that provides such precise control for experimentation. I would think that watching a spark as the pulses change would reveal some very interesting things.

Here’s another thing I wonder about – How does storing the radiant energy in a battery or capacitor change it?

I have firmware version 2.02. I haven't tried actually saving any waveforms yet, I'll try it and let you know if it worked.

BTW my hardware is the DSO201. I upgraded to version 2.21 for the library and 2.31 for the application. Looks just the same as your interface and handles 2GB flash cards. I did find out some more about Paul’s firmware with the UI I like the best. Unfortunately, it is not open source and the code isn’t available. Furthermore, he just posted his last update and will not be developing it further. Dead end, unfortunately.

This fellow is authoring a firmware with yet another interface. His article/review on the DSO Nano here is interesting and informative. It’s written in Spanish, but translates pretty well in babelfish:

Lordblacksuca

So I got me some wave files finally and I just have to compare them with what I’m used to getting out of this antique Heath Kit Lab Scope:



Here are square wave pulses generated by a 555 timer circuit:





Here is the capacitor charging cycle from the same circuit:





I’ve been checking out what people are saying on various forums about the Nano and the criticisms are awfully biased. This one channel scope is not going to be the thing to get if you’re working with digital logic. But the people who are criticizing its 1Meg sampling rate are comparing it to storage and USB scopes that are much more expensive. Anything else in its price range can’t handle frequencies higher than 20kHz.

Actually, I have to try it sooner then expected. I have blackout last night and my emergency light run out of battery. Fortunately my radiant sleeping aid available and I use it to light 6 LED in series at about two candle light.

Now I wonder if parallel is better, because stingo reduce consumption with more load, and parallel should force it...

50V is measured output from 3V source.

Wow! What kind of coil got you these results?

1A 24V transformer without core. Kinda cheating though, the battery seems to be conditioned by my radiant charger and seems to exceed normal.

However, I’m inclined to think that a specific frequency and pulse width changes the nature of the radiant energy being output. And so intend to develop a circuit that provides such precise control for experimentation. I would think that watching a spark as the pulses change would reveal some very interesting things.

Yes, I agree to that. But I spesifically after the radiant produced by the steepest signal for health reason. I look for a way to drive the transistor with spike. I think stingo use radiant spike as trigger.

During this time, Tesla found shorter impulse lengths where the heating effect disappeared altogether, rendering the radiance absolutely harmless. These impulse trains were so very high that the deepest nerves of one's body could not sense the permeating radiant energy field. Now he could
pursue his vision of broadcast energy systems without fear of rendering to humanity a technological curse, rather than a true blessing.

You have seen this circuit of mine? this circuit bellow have many wrong part.


If you want to compare, try with and without duty-cycle-trick-diode. I forget which one I use. To reduce 555 consumption use more than 10K ohm duty-cycle-resistor. And to compensate for lowered frequency, use pico Farad capacitor, or don't use it at all. 100ohm for PNP base is too low, I use 10K on my charger. You might also try other circuit variation but keep the PNP+NPN combination.

The 555 can not be called precise because frequency wander with input voltage. If you use battery, when your circuit draw more power the voltage change, and in turn will change circuit frequency.

Here’s another thing I wonder about – How does storing the radiant energy in a battery or capacitor change it?

Some have great success with capacitor. Try with big capacity and use it to charge battery with relay or other mechanical switch.


1MHz scope still good enough for our experiment .

[7imix]

yep. Parallel is better. That's what I ran in my experiment, I should have made it more clear.

I see. Thanks .

But I spesifically after the radiant produced by the steepest signal for health reason

??? – I’m not understanding – Do you mean that the sharpest (shortest) pulse produces the best radiant energy for health purposes? Can you elaborate further?

You have seen this circuit of mine?

Yes, that’s the one I was referring to earlier.

this circuit bellow have many wrong part.

What’s important is it showed me how to feed the Stingo transistors with the 555 signal.

I have my own ideas about how to do the 555 timer part. I’ll be replacing the timing resistors with potentiometers, and configuring it differently to control frequency and pulse width, independently. Your configuration with the diode gives you independent control of Mark and Space, which do add up to a frequency, but not in a single dial way. I would also decouple the power to the timer more by adding a big capacitor in parallel to the power rails and a resistor in series with pin 8 to help it deal with the spikes.

To reduce 555 consumption…

when your circuit draw more power the voltage change, and in turn will change circuit frequency.

Using a CMOS 555 reduces these issues considerably. It consumes much lower power, and its timing is less sensitive to voltage changes. I’ve been using TLC555CP. They are delicate, however, and in my experience, the timing varies (usually faster) from non CMOS ones like the NE555, even though the formulas look the same on the spec sheets. This is one of the reasons I desired accurate frequency measurement and picked up the Nano.

Some have great success with capacitor. Try with big capacity and use it to charge battery with relay or other mechanical switch.

Thanks for the tech observations, but the question I’m really pondering is: How different will the stored radiant energy be from that being given off fresh by an oscillating circuit? Does it really come out the same if stored and pulsed out later? Or are the qualities/effects of radiant energy coming right out of a generating circuit as spiked pulses unique?

Sucahyo, I forgot to ask you what that single coil is in your dual Stingo configuration? I assume the other one is a car coil.

yep. Parallel is better.

Good info! Thanks.

That is what I am interested in seeing. The bemf is not as interesting to me as driving the sharp sloped spikes into a tesla transformer with a termination. (probably a dead light bulb) Since the bifilar coil reduces back emf through self induction (I am assuming...) this setup should produce maximum dielectric induction, or displacement current. That is what I am most interested in researching.

Yes…yes…good stuff! I may not be as articulate as some of the heavies on this forum who have debated these issues, but intuitively, I feel that electrons, protons and neutrons are all carriers for a transcendental energy. The radiant technology we are thrashing out here seems to work with those transcendental units and bypass the physical carriers normally involved. For instance, semiconductor technology acknowledges the existence of positive holes as well as negative electrons as active agents. I think neutrons relate as carriers to magnetism. And of course, there’s something, a unified transcendental force that is the source of all electromagnetic phenomena. Relating to your investigations, Tesla seems to have discovered that the bifilar coil filters the reverse electromotive force while passing on the radiant energetic reaction to the spike. Something worthy of my further investigation too! Thanks for reminding me.

[sucahyo]

??? – I’m not understanding – Do you mean that the sharpest (shortest) pulse produces the best radiant energy for health purposes? Can you elaborate further?

Yes. I believe that the sharpest pulse (may not be shortest) produce healthier radiation. I feel it from my past experiment prior PNP+NPN combination.

Tesla used very fast mechanical current disrupter. With solid state I am thinking that we have to use the sharpest drive signal. There is other reference which I forgot where that mention that stinging sensation reduce with higher switching, changing to warmth, and then cool.

Coincidentally, the most abrupt switching, the most sharp signal, also produce better efficiency.

I would also decouple the power to the timer more by adding a big capacitor in parallel to the power rails and a resistor in series with pin 8 to help it deal with the spikes.

I see. What you want to use 555 for?

BTW, can you test charging efficiency once you done building 555 one? From what I recall, stingo is twice more efficient than my 555 version. But I still use a power hungry 555 at that time.

Using a CMOS 555 reduces these issues considerably. It consumes much lower power, and its timing is less sensitive to voltage changes. I’ve been using TLC555CP. They are delicate, however, and in my experience, the timing varies (usually faster) from non CMOS ones like the NE555, even though the formulas look the same on the spec sheets.

I see. thanks for the info. My lowest current consumption with 555 is under 10mA.

Does it really come out the same if stored and pulsed out later? Or are the qualities/effects of radiant energy coming right out of a generating circuit as spiked pulses unique?

Capacitor and battery will partially change the radiant to normal electricity. If you charge it directly with radiant output the battery will stays cool. If you use capacitor dumping mechanism the battery will get hot.

I find that even capacitor in parallel with charged battery will make the charging hotter.

Sucahyo, I forgot to ask you what that single coil is in your dual Stingo configuration? I assume the other one is a car coil.

toroid wound coil like the one I post before. That just my actual circuit. The coil can be anything and you still get better efficiency with two.

Relating to your investigations, Tesla seems to have discovered that the bifilar coil filters the reverse electromotive force while passing on the radiant energetic reaction to the spike.

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.
