  • VTTC- Vacuum Tube Tesla Coil I warmly welcome all fans of high voltage.
    I would like to introduce my tube tesla coil on the GU-81M lamp.
    The coil was created according to the diagram on page Link
    And what to write here, I wish you good luck in building the tlock and meter coil 1998
    I used this scheme (not really)

    Where it is written that it must be at the bottom. And the pattern is the opposite because it was easier to paint, if I'm sorry I'm sorry

    Very nice :) I support all activities related to TC ;) Tlock is again confused by concepts. The primary winding is to be below the secondary one in DRSSTC in other coils, but this is not important, but you can experiment. I am planning to make an attempt to change the feedback to lower in my SSTC and in DRSSTC I have already convinced that the secondary MUST be above the original because otherwise too large coupling results in punctures on the original one. Generally, the principle sounds - if there are no secondary breakthroughs - the original one has no reason to lower the feedback. If we are reducing the feedback by extending the secondary from the original. There is an unspoken rule that says it is better not to drill holes in the secondary pipe wall. With this coil, it does not matter. With a bigger one, this is the first place where a ;) breakdown will occur ;) So if you planned something bigger remember about it.

    Welcome At the beginning, congratulations for the author, the design is decently made. I have one question where did you buy a GU-81 lamp? I have been hunting for her for some time and at what price can I buy it?

    About 3-4 months ago I saw GU-81 on the Allegro for PLN 50. You need to check there a few times a week, and maybe someone will add.

    Well, I think so too, but I made my work on the opera and it works correctly already.

    Welcome back!!
    I have a question, how to make two lamps work to achieve more power? I would like to use two to increase the power.

    I just want to point out that the above-mentioned coil uses this driver: Staccato Controller . In short, it allows you to squeeze more out of the lamp by shortening the cycle.

    I am asking the author of the topic to include the correct link to the project's sources and to improve the photos - it was hard to turn the right side before loading?

    Very nice construction :)
    I have to do something like this :)
    And how many coils did you give to the coil ?? :)

    Tlock this picture is a different lamp and another power, and the images from lukasb9 are nicer because they did it with a long exposure time (eg night mode with the flash off).
    And when it comes to the link, this is ok, the site is not open at all, so it gives a link to the post https://www.elektroda.pl/rtvforum/topic971433.html
    The film, however, will be at school ... But it gives you a link to another http://www.youtube.com/watch?v=wNFLibUZOTY where the effects are similar, I am interested in connecting this foot next to the anode S1. It hunts for one more GU 81 to combine them for more power. The lamp in my heater is in the new housing I gave the microwave fan, I'm still waiting for the heel switches.
    And tlock probably was right, see here how it is done http://www.teslacoil.it/

    Nice Tesla :spoko: transformers

    I have a question - what kind of capacitor and where did you buy it?

    Great design, I like this ;) lamp
    I have a question - where did you get the power supply from?
    From what I know for the very glow you need 12V / 10A.

    Greetings.

    Hello

    trzaska456 - it looks like your tesla is not tuned to resonance, just like a colleague wrote above, make taps on the top 10 windings of the primary winding and connect one by one looking for the maximum. If you get a definite maximum (one and the other side of the discharge will be reduced), take care of the feedback. Try to increase the number of windings of the coupling winding, reduce the value of the grid resistor. On the GU81, when powering from a transformer from a microwave and using a multiplier, you can get 30cm long discharges.
    As for the explanation of not working links to my site - everything will work at the beginning of the week.

    After reducing the resistor from 1k? to 2?, the effect improves (longer sparks), and what you think about it to connect two motifs with each other. Normally, the MOT takes me 4A and with a 0? resistor takes me 7A
    PS: I added a movie with my :D coil

    Ok I changed the primary winding to the resonant winding by removing some coils and increased the distance between them to 2cm and the effects improved, the sparks are about 24cm max. And as for the toroid, I read somewhere that no lamps are needed

    It is not needed in the same way as in SSTC ;) Read tesla will work without it, but combining with the right one can improve the effects. It can also aggravate :) but in the end the fun with TC is based on experimenting with ;) so it's worth ;) with the torus.

    I removed 7 scrolls from the secondary one and it is even better, and tell me why this 1k Ohm resistor may be worth it, as on the website http://www.teslacoil.it/

    Quote:
    rolled back 7 rolls from secondary
    for what? not much will change this secondary inductance. And what follows and the resonant frequency.

    Everyone says that you will tune the resonant frequencies by changing the number of windings of the primary winding (you must find a clear maximum), then only combine with the wire resistor (it sets the working point of the lamp).
    Another thing you can try to move the secondary winding relative to the original one, then you change the coupling factor (here also look for the maximum), only after such an operation you will probably need to re-tune the primary part.

    How does it work? are these sparks harmless?
    For how much can you buy something (already done?)
