TA2WK (aka TA1LSX)
Добавлен 27 окт 2020
Welcome to my video channel.
I started using the TA2WK callsign from 25 November 2022. My old callsign was TA1LSX and before that it was TB1DJU.

How to build a homebrew butterfly capacitor for loop antenna
Просмотров 20 тыс.3 года назад
I just wanted to show how easy to build a homebrew air variable and high voltage butterfly capacitor. I designed and used 3D printed endplates. They are free and can be downloaded from www.thingiverse.com/thing:4573307 If you want to see instructions and BOM part list visit my blog ENGLISH: www.ta2wk.com/high-voltage-diy-air-capacitor-for-magnetic-loop-antennas/ TURKISH: www.ta2wk.com/manyetik-...

Used 3D printed endplates and looks fancy. 3D Printable STL files for endplates panels can be found at following sites: cults3d.com/en/3d-model/various/homebrew-butterfly-capacitor www.thingiverse.com/thing:4573307 If you want to see instructions and BOM part list visit my blog ENGLISH: www.ta2wk.com/high-voltage-diy-air-capacitor-for-magnetic-loop-antennas/ TURKISH: www.ta2wk.com/manyetik-loop...
Thank you and appreciate your effort. Greetings to you from Turkey .
Teşekkürler, 73
What is the minimum & max capacitance value of the 5 set 6mm apart. ZL4MBW
god job
Nice job.
Well that was a stupid video.
Instead of using air dielectric, have you thought about just printing that as part of the fixture? I was just looking into doing this. PLA has a dielectric constant of 3 to air of 1; PLA dielectric breakdown is 30kV/mm to 3kV/mm for air. This should increase power handling and decrease capacitor size for the same capacitance range.
Interesting idea. Can you please explain that a bit more. Where can we place printed PLA plastics parts? Between the stators? You can email me at erhan@ta1lsx.com
@@TA2WK-TR I was thinking of printing the stator and rotor vanes directly and at the desired thickness (100% infill of course). Copper tape the plastic. The overall configuration probably wouldn't be rotating butterfly though. However, since you've already laser cut both, perhaps print just inserts into the air gap.
Very nicely done! I will be contacting you soon on Etsy!
Crazy I want to make one of those to tune my high frecuency tesla coil
Hi, can be replaced with SI4844-A10-GU. can`t find the SI4735. Thanks in advance!!
what is the plate thickness and what metal please?
Its 1mm. I have 5mm and 6mm spacers. So they give us 2mm and 2.5mm spacing.
Wooooooooow super LIKE👍
👍 Nice 👍
Thank you for the video, and especially the links to sources and printing plans. Great project!
Long term durability is questionable. The plate and shafts should be silver plated and brazed together to prevent corrosion from forming. Corrosion will cause higher plate to plate resistance.
Nope. I use 304 grade stainless steel plates and rods and high grade aluminum plates. I have a few caps for my own use for more than 2 years and nothing happened yet.
Hello, can bay the aluminum plat from Chile ??
Yes, you can order from www.ebay.com/str/TA1LSXStore or email me how many plates you need? erhan@ta2wk.com
Nice work! Whats min and max pf?
It depends on number of plate sets. Email me I can send you pf table erhan@ta1lsx.com
Nice work.
Thanks, excellent.👍🇬🇧
Merhaba bu chip in performansı genel olarak nasıl. Fm de gayet iyi gibi. Am mw gibi bandlarda iyi midir. TA4İRS 73.
Gayet iyi. RUclips da si4735 aratırsanız bolca örnek proje var kısa dalga ve orta dalga kabiliyetini gösteren
Will I have to pay import tax for delivery to UK. Iam intrested in buying quite a few of these please.
After brexit you will pay VAT 20% for everything you bring from outside of the UK. As far as I know there is no other import tax if the goods value does not exceed 185 gbp. Check this document www.avalara.com/vatlive/en/vat-news/uk-post-brexit-vat-on-e-commerce-b2c-imports.html You can buy plates from www.Etsy.com/shop/snowistcorner and Etsy calculates the necessary taxes during check out.

Thanks. When I copy and paste some longer links truncated. Corrected.
