I don't recommend trying to run audio into this. I assume you want to modulate the plasma intensity and this circuit is simply not designed for that. Also there is high voltage, a danger not only to you but to your audio equipment. The circuit is a high frequency oscillator and trying to modulate it with audio frequencies will probably just kill the output. But if you insist, maybe try adding the audio as a ripple on the input power supply. The capacitors will short out the higher frequency audio but you should see some effect. Caution: component voltage limits in these circuits are very tight and some capacitors may not tolerate much AC. Experiment at your own risk! I suggest you lower the DC input voltage if you are adding in some AC.

I know, all three of the old ribbon mics I tested were great. Rather heavy, though. I remember once using a 1950s motion picture mic boom and wondering why it was strong enough to hold a pail of bricks. After trying out these old ribbon mics, I understand why!

Glad it was helpful!

Sorry, no, it was just borrowed for the demo. But I think such small tube-type guitar amps can still be found if you look around online. Of course they usually need new tubes and new capacitors.

@@1-minute-electronics This specific model is hard to find. I have one just like it and plan to build a copy. Thanks for the reply.

What module to get and where to get it? Some of this is already in the description, but some of that seems to have been cut off, so I will repeat it here. Read reviews of the module you intend to buy. For example, there was a $10 module on Amazon that I ended up buying. There was also a very similar module that seemed a better deal at two for $11, but when you read the reviews it looked like only about half of these actually worked, so you would be worse off. Quite a few replacement modules are defective as purchased or go bad fairly soon or fail immediately because of incorrect installation. These modules are easily destroyed by static electricity. Don't work on them in dry weather and try not to shuffle your feet on the carpet before touching the lamp. You can ground yourself when working on the unplugged lamp, but for heavens sake don't ground yourself when testing a plugged-in touch lamp. In the lamp I repaired, the LED bulb had apparently been damaged by the failing touch module and had to be replaced before the lamp would work. For testing touch lamps, new or old, use regular incandescent or halogen bulbs, not LED bulbs. Don't even think of using a CFL bulb. And be sure any LED bulb used is labeled as okay for dimming. The modules I looked at do not use a relay, just semiconductors, so there is always a risk of full line voltage getting to the lamp body (and YOUR body), especially if an isolation capacitor fails. Obviously, people are not dropping dead in large numbers, so any leakage current is likely quite small, but I would still not locate such a lamp near small children or elderly people. These lamps contain a sealed module with usually 4 wires - live, neutral, light, lamp base. The lamp base (or stand or shade) must be metal, though it can be painted, and must be electrically floating, not connected to earth ground. PLEASE UNDERSTAND THAT MAKING A WRONG CONNECTION CAN PUT FULL LINE VOLTAGE ON THE LAMP BASE AND BODY! TRIPLE CHECK ALL CONNECTIONS AGAINST THE DIAGRAM THAT COMES WITH THE TOUCH MODULE. DO NOT PLUG IN THE LAMP UNTIL YOU HAVE CHECKED WITH A MULTIMETER (ON THE OHMS SCALE) THAT THERE IS NO CONNECTION BETWEEN BARE METAL PARTS OF THE LAMP BASE/CASE/BODY AND EACH OF THE CONTACTS ON THE POWER PLUG. Carefully inspect all installed wire nuts (the plastic screw-on connectors) to be sure they are tight and no strands of wire are poking out. In selecting a replacement touch control module, you need to consider: size - it must fit in the available space. number of wires. voltage - 120 volt or 220-240 volt. frequency - 50 Hz or 60 Hz. dimming - is it on/off or 3-way (low-medium-high-off). power rating - many will handle up to 150 watts but some are limited to 100 watts or less. LED support - many specify incandescent lamps only - you want one that also works with LED bulbs. But not all LED bulbs will work. The bulb must be designed for dimming, but even so it may not dim properly. ================ The module I bought was: www.amazon.com/gp/product/B07QF1B9GR/ref=ox_sc_act_title_1?smid=A1W8R3OQ5VZE8C&psc=1 3 Way Touch Sensor dimmer, Touch lamp Repair kit Control Module, Replacement Sensor, Touch Switch, 150Watt. $9.99 Brand: ESC 4.3 out of 5 stars 4,039 ratings This is not a product endorsement. It was just the one I used. I have no idea if these are reliable or safe or a good buy. (Mine is still working after a year or so.) You can get cheaper ones from China but I suspect they are not all that reliable.

Well, Boeing can reuse the Starliner capsule after a six-month refurbishment, assuming that the thruster problems are fixed. The Atlas rocket cannot be reused and the supply of its Russian engines is limited. Boeing plans to switch to Vulcan-Centaur, but I don't think that can be reused either. As a last resort, the Starliner can be fitted on a SpaceX Falcon 9.

It is getting there. Maybe in the next test they will try to land the first stage back at the launch site.

Yes! Getting better with each launch. Still, it looked like a lot of heat damage.

Yes. The Atlas, even the latest Atlas 5, is an old design with a Russian RD-180 main engine.

I don't know, she seems well dressed. Of course, she was the commander of the station and knew she would be appearing on camera. Hey, look up pictures of Italian astronaut Samantha Cristoforetti, who took a Star Trek uniform with her to wear at the ISS.

Yup. Hair tends to float up in microgravity. Also they use dry shampoo to save water and avoid water globules floating around.

"what are you saying " 😂

Hair sort of floats out in microgravity. And Suni had been up there a long time and they don't exactly have beauty parlors in space -- they use dry shampoo and rough Russian towels to clean hair. And, indeed, the space station is awash in wiring and air ducts.

This is what it is really like in space.

Why can't they do a continuous shot? Because the Vomit comet needs to regain altitude.

@@mrsir2378mate you are an absolute moron of course you can’t understand why a short UA-cam clip isn’t continuous.

Yup.. I can’t wait to hear about fish eye lenses.

These were continuous shots - see the long version on this channel. These had to be cut into under-a-minute sections to meet YT shorts requirements.

They use dry shampoo to avoid having water globules floating around. Not everyone has hair problems. NASA astronaut Judith Resnik had long curly hair that always looked beautiful in space. Unfortunately she was part of the crew killed in the Space Shuttle Challenger disaster.

how is it fake you can see it easily......

SpaceX Starlink is designed to fill in cell phone reception in areas not served by cell towers. People visiting Mars is certain, though a civilization there is not.

Exist

omg hi iosa im firstt

I suspect government hasn't a clue, but, yes, the problem is not pollution or even gradual warming. It is the unexpected, the unanticipated.

You don't need to believe or participate. You are not involved. It is not your money. But it is interesting that someone is buying insurance for the human race.

I doubt if anyone thinks a travel service to Mars will make much money, at least in the next hundred years. Well, maybe Elon does, but I doubt even that. Breakeven may be possible. But lots of things are done for reasons other than profit.

@@1-minute-electronics No, but even to consider it as a sensible alternate base for humankind at any stage is idiotic in the extreme. It will always be cheaper to fix our problems here, than to recreate living conditions and relocate to Mars. Seems that some people are just too commited to ending life of Earth.

I don't want to get into politics, but if one looks into the history of "improving our planet" the results are often negative.

There is a chance your house will burn down. So you buy insurance. There is a chance the human race will be wiped out on Earth. So you build a small but self-contained outpost on another planet.

Remember that Elon usually delivers but is also usually late. I would say 20 years to a human visiting Mars but 40 years to anything like a permanent base.

Mars is a terrible place, far worse than any Earth desert. But it is the only choice, at least for now, for an off-world colony that could preserve human life long-term if things on Earth don't work out.

I think he was talking about civilization now versus after a major atomic war, but yes there has been a long-term assumption of growth - every new town, every investor, every real-estate agent, makes such assumptions. But there is now a movement away from the idea of constant growth. Also, the population will crash - that is another thing Elon is often harping on.
