Hi all, Hi erfandl, yes, the 2n3906 seems to work good,also 2n2907 and 2n4403 works good also.

I notice the pn4248 does not have the same gain and i can see that first hand with my setup,
as i found another one in my salvage stash. ;D

I'm testing two 2n3906's in parallel at the moment.

The $50 function generator
« Reply #271 on: June 20, 2018, 06:57:43 PM »
All--- I went ahead and ordered one of those $50 function generators like what Dr. Jones fried attempting to replicate the Dr. Stiffler latest experiments.  Building up a signal generator specific to this project isn't going to work for me.  My hope is that I can isolate the function generator to prevent the failure Dr. Jones had.  I will probably use this tool for many other projects -- if I can keep it alive.  If it doesn't do anything for this particular project so be it.  If I kill it the cost was not much.
  Here is the unit I bought off EBay.  It ships for free from a California source where I live.

Lidmotor - very nice, you've been missing one of those !
It has the 20Vpp and also the measurement function is intriguing.
What's a Symplectic Pulse ?   :o

Oh and it has this line in the ad:
"Protection    All signals output can work above 60s under the condition of load short circuit"


HiLetgo are sending another AD9850, so all's good on that front.

Slider---- This should be fun to see if I can get this function generator to at least do what those little crystal oscillators I have do.  As you and I know the 'Exciters' energize the whole area around the device so trying to isolate and protect this generator might be tricky.  The crystal oscillators tolerated it just fine so I am wondering what went wrong with the Dr. Jones experiment.
  I have no idea what a Symplectic signal is.  I tried looking it up but got confusing answers from Google.  Perhaps I'm too symple minded? Ha.
  I hope you get your AD9850 eventually running.  Had you gotten your project instantly working I might have gone that direction.

Instantly working for some projects is about the same as "I'll just print out this PDF and be right with you". There's usually a niggle of something.
There may be a need to protect the return path of the output signal with something like an optical isolator. Am not sure of the speed they max out at, but can be as simple as an I/R LED and detector inside a black straw. Another route may be to use a transistor as a high speed switch, such that only it blows if anything odd happens.

Slider---  I was thinking of using a transistor to isolate the function generator.  I will probably try a fast diode and a cap on the way to the transistor base.  I plan on just lighting up a few leds so maybe that is not even needed.  I would hate to zap the thing in the first 5 minutes.

 Good news today!  I built up that simple one transistor crystal circuit you showed a ways back and got it to work using a 7MHz  2 pin crystal.  I had to fiddle around with cap values and several different  L3 coils but finally got it light leds down one wire.  Pretty cool.  Ran it off a 9v battery.  I will play around with the neat little circuit more tomorrow. I wish more people would try it.

Hi all, I'm trying some different leds with the same exciter setup.
I picked up a 4 pack of Utilitech 14 watt 1600 lumens, led tube lamps or linear lamps, the ones meant to replace those flourescent electronic ballast lights.
On clearance for 5 bucks, and they are encased in glass.
So, after hooking one up, realized it must have circuitry inside.
I then proceeded to break the entire glass envelope and slice all the glass off, that was attached with some silicone to a strip of aluminum backplate.
It's just one long led strip of 52 leds, though i cut one off and another shorter strip of 24 leds, cut another one off also.
I separated the two strips and they both light up very well with this exciter.
The 24 led strip is blinding at 520 milliwatts.
I had to scrape a couple spots to solder wire connections.
I will test the 52 led strip tomorrow.
The nice thing is, i essentially have 4 strips of 24 leds in series and 4 strips of 52 leds in series for only 5 dollars, with only a little work to get those strips, cutting off the circuitry and also being careful, use gloves. ;)
peace love light

Edit: another interesting thing, when you touch the aluminum back plate strip, i can see the leds light up slightly, with the circuit not oscillating.

Lidmotor happy for you, arbitrary, sweep, frequency counter, precision signal.

Slider good one, There are a lot of diodes on the SEC 18 the remote idea with opto coupling is interesting.
The circuit for fiber optic transmits and receives of sine in the radio frequency over a few meters or less of fiber cable turns into pulse... the turn-on voltage of the led is received at the photo transistor at the led turn on voltage.
It is an interesting shape because it has rounded edges and a narrow triangle offset above base line gives a narrow pulse. A sine into AV plug, the half wave into photo transistor should be slightly more narrow, arbitrary function could simulate that. The signal generator can be placed behind while the photo transistor and final amplifier stage could be on the bench keeping a distance for delicate circuitry might be helpful.
There should be some results coming up on the 13W led light. (not my video)

   Lidmotor:   I am also looking into building a crystal oscillator circuit. I've pulled out several crystals from my junk pile.
So, I have the following crystal ready to test, the 3.5k, 4K, 7,2K, 8k, and the closest to the 13.45K that the Doc tunes to, is a 12k crystal. I also have a 20k, if needed, and I can further tune the crystal oscillator by the ferrite rod inside the Tesla secondary coil. 
   However, as Gyula mentioned, the main L3 type coil needs to be at the same frequency as the running oscillator frequency for the best effects. This I will try to do afterwards.
  I have also managed to make the 120v reflector led bulb that I had previously shown a picture of, to light by capacitance. By placing the two diodes on it, and placing the whole bulb on an aluminum base, so that it lights up now. May not work as well as the right led bulb with the aluminum back plate, but it lights up pretty well, in any case.  So, I'm looking into just what crystal oscillator circuit to use, one the can output enough power to properly light the bulb(s).
  Any ideas are welcome...
   BTW: I have never had any problems with my 2MHz SG being affected by HV, it's old, but still works fine. It's just too low powered for this project, as the output has to be able to light neon bulbs when connected to an oscillator, not just leds.

   Here's some pics of the bulbs that I'm using. I got the round led 120v reflector spot light bulb to light off of capacitance. It's ready for the crystal oscillator circuit.

   The filament bulb lights the brightest, (bang to the buck), but I can only make it light with a single wire connection to it, to one side of the filaments. It's a 40w equilavent, and it lights quite bright.

Hi all, i realized this morning, that the utilitech led tube lamp is actually 3 series strings of 26 leds wired in parallel, printed on a fairly thick aluminum strip.
So i cut them to make 3 nice led strips.

These might work well for the stiffler experiments, with the aluminum back plate.

They are also very efficient, rated at 114 lumens per watt.

The led strip lighted is 24 leds, because i cut off the circuitry on the ends and a couple leds went with it.
It is blinding bright for around .5 watts input.

Nick - that's one of those Dendera bulbs from Egypt  :P
It looks great, with the warm glow.

uV - TK's video was great, the way that the photo-transistor followed the output exactly.
Perhaps it could also be a wave shaping method on an output, to remove or introduce edges. 

SkyWatcher - The strips seem similar to LED automotive bulbs. Have got a couple of headlight bulbs here where there are about 100 LED's on the things. I cut strips off them. Years ago I used to go to Dollar Tree to get closet push lights that had 3x 5mm LED's on them and now for not much more there are those automotive LED's !



Side track:
Am glad that the crystal circuit is being built by others, It's easy to make and i'm thinking that if something efficient to the Doc's principles can be built for lighting, a crystal would effectively 'hard code' a frequency of that operation for replications. Ideally 13.6MHz, yet it all has to be worked out with some flexibility based on results so far. We all could perhaps tweak and improve something with known values.
I'm not versed well enough to fully expand the idea yet, but, the overview is a circuit where the output coil(s) are tuned to the crystal frequency. The circuit has a sensible but limited wireless field around a desk lamp. Other devices/objects/circuits can be powered similarly to if they were using solar cells around the lamp. No antennas or bulky coil pickups...more like Qi, with a simple pancake coil and multiple SMD diode array.
Can it ever charge a phone ? not with the requirement of >450mA for smartphones, but it may well be able to power a lot of other handy gadgets such as calculators, LCD games, small fans and AA chargers. Standardised, where things are thrown near the lamp and they just work.   

Another thought is about Home Automation away from WiFi and Bluetooth.
A switch box could be plugged in to the wall mains. Inside, it has a step-down circuit to 5V (so could have a couple of USB outputs as secondary function). The box has several switches on the front, relating to lamps or other devices in the house. Flick a switch and the crystal circuit for a set value is started up. That frequency goes down the mains wiring and somewhere in the house a plugged in device begins to oscillate because of that frequency. Its circuit runs.
Usage example would be going to the toilet at night. Flick just 1 switch in the bedroom and 3 different lights come on to light the way to the bathroom.
If there are 6 switch frequencies, they could be known as 1,2,3,4,5,6. All devices with a 3 written on them switch on when the 3 switch is in operation. All '1' devices may use a 20V step-up driver from the switch box and would be used for lighting lamps similar to the Doc's Cree board.
The need for specific resonance conditions then works to our favour, locking out the other devices.
Anything plugged in to wall sockets only needs to be connected to 1 pin, making the whole thing far safer than traditional mains outlets.
A scavenger circuit could remove fears of electro smog being unhealthy in the house, doubling as a power indicator light as it soaks up excess field energies.
Also important, only the switch box is actually mains powered.

It was given before, but here's my version of the Simple Crystal Oscillator. I used a BC337-25 transistor, also tested it with a VHF transistor, MPSH10, which also worked well but didn't have the amplitude of the 337. I think just about any NPN would work in this circuit.

The original circuit made a signal but didn't have the ability to really drive anything. I added a 74c14 hex Schmitt trigger inverter and ran the SCO's output through 3 of the inverter stages, which helped to square up the signal and make it capable of actually driving some small load (like a mosfet driver or a transistor). The inverter is pretty slow though so this version only works best for lower frequencies. I also added some bulk capacitance at the power entry point, which also helped to clean up the waveforms, both before and after the Schmitt trigger inverter stages.

Yellow is SCO output before Schmitt trigger stages, blue is after.  Input is about 6.5 volts from a regulated PSU.

What do you mean the the 74 series chip is slow ?  how slow here i have a CMOS chip CD4060 with a 13.4Mhz chip it's fast I found this
in looking for 432hz multiples up to 1.3 mhz region, even a 4011 will clap away at 15mhz easy all with a 8volt power rail, you might not be so lucky
 with if using older stock.

This old bulb of Nick's they remind me of some of the old junk that worked of DC from years a go now you can get them in hard ware stores allover.
I was called a Beretta voltage dropper. I had a knowledgeable grandfather if any ones asking.
