Myself answering a question about replicating Tesla and other inventor's work,
that we must stay focused on understanding the principles of operation rather than just trying to build a 'free energy' or crazy sci-fi device blindly.

This is meant to serve as a simple crash course for those who are interested in using the relatively inexpensive Vector Network Analyzer sold by sdr-kits.net in order to test and tune a simple Tesla Extra coil.

Turning up the power to the Tesla system and powering more substantial loads through a single wire and a 200ma fuse.

This was somewhat cobbled-together test as I'm still working at finishing+tuning the second Tesla Magnifying Transmitter. A matched set should perform much better :-)

A brief and quite cobbled-together experiment following some preliminary long-range telluric testing performed the day prior.

The experiment seems to suggest a unique transmission mode may indeed exist when two Tesla coils are used in tandem to transfer power between each-other.

I'm not the kind of person to do public speaking, but there's only a dozen people alive that could build a proper Tesla Coil, and unless that number goes up the tech might easily be lost for another hundred years.

Short experiment lighting a florescent bulb with a single monopolar Tesla extra coil using just a function generator.

The function generator was later tested with an RF wattmeter and measured between 0.27 and 0.30 watts output around this frequency.

Experimenting with a pair of Tesla Coils and a homemade mercury vapor bulb. Interesting formations seem to develop as the mercury vapor plasma becomes energized, forming multiple distinct rings and patterns in the 'null space' where the fields are supposed to cancel...

Doing some live testing with a modulated resonant high voltage system aka Musical Tesla Coil.

Livestreamed 6/18/2022

Testing and tuning a new 5mhz Tesla Coil with a high-power HAM radio linear amplifier.

Testing various configurations for the Musical Tesla Coil experiment.
Driving directly from an EIMAC 304TL tube by modulating the grid via HAM radio.

Quality is subpar due to the low modulation, but sparks are more prominent due to the higher-voltage.

Song is Wintergatan's 'marble machine' song:

Putting a new amplifier through the ropes, making sure the magic smoke doesn't leak out when I turn up the power.

The amp is being used in some upcoming high-power Tesla Coil experiments. :-)

Finally traced the audio quality problem with the musical Tesla Coil;
turns out the HAM radio has a built-in bandpass filter that limits roughly to human speech range (~800hz-4khz).
Explains why the highs were getting cut off in most of the songs as well as the lows.

Gonna take a little engineering to fix though, since I'll need to use a function generator to modulate AM instead of the HAM radio....

Musical Tesla coil ~7mhz powering a nearby Tesla replica brush bulb
Total power around 100-150w, SWR ~2

Mostly been experimenting with linear amplifiers today (not very photogenic),
but since the frequency and matching was super close on one of the coils, I tried tuning it in, cranking up the power to ~60-80w, modulating it to some music with the HAM radio.ūüėČ

The sound you hear is coming from the spark at the end of the coil.

It's not very loud, but that's mostly because the limited power available. I was hoping to have the 3kw amp working this weekend to show the kind of volume and fidelity that can come from such a setup.‚ö°‚ö°

Quality is pretty low too since I lacked a proper microphone coupler to match it to the phone.

Incandescent bulb lighting under longitudinal waves produced in a Tesla Magnifying Transmitter

Built around Dec2021 to Feb2022. It was a thoughtful christmas present consisting of a heavy pile of raw foundry castings that needed to be machined on a lathe+mill.

Showing off one of the neat features of a 'real' Tesla Coil.

Probably >99% of 'Tesla Coils' online are in fact normal induction coils (also known as Lodge coils in Tesla's era). Those are largely magnetic devices, while a real Tesla Coil focuses much more heavily on the dielectric field.

This example uses a coil with 1/4wave resonance around 1.4mhz, and a relatively high Q factor around 200.
Higher Q = stronger resonance and a much 'tighter' signal.

You can detect the oscillations quite easily with an oscilloscope probe placed several feet away from the coil. You can measure several hundred volts if the probe is placed close to the coil (from the <20v being input from the function generator).

Also note that only one lead of the function gen is connected. Ground lead can be used in other experiments but in this case it is not needed at all.

pretty neat, huh?

I started by teaching him to sit/shake, and once he knew that I would hold the button in my hand so his paw would push the button when he 'shook'.
Then I put the button on the ground and eventually it 'clicked' with him one day and he learned how to push it voluntarily.
Took a couple weeks to get this far.

Now that he knows 'treat' I plan on expanding to a few more simple words like 'outside' and 'toy', putting them in different locations so he associates the button easier.

Maybe one day he'll be as articulate as Stella? -->

Rough test of the PMA wind turbine alternator with the 1/4hp steam engine machined from castings last month.

The right music makes a boring job so much more interesting.

Testing+tuning the Tesla coil.
Progress is still a ways off, but I did get it running well enough to light bulbs with just the function generator

Enjoy :-)
