air variable capacitor 3d models

DKS-8 split section air variable capacitor, 2x 15 - 280 pF, rated for 2 kV, used in power amplifiers and transmatch devices in HF applications

DK-8 single section air variable capacitor, 15 - 600 pF, rated for 2 kV, used in power ampilfiers and transmatch devices in HF applications

These are insulators/isolators for air variable capacitors used in tube radio circuits. More will be added as needed. These insulators are utilized in my modern tube Theremin design. Insulator_C-V100P Insulating collar for Antique Electronics Supply...

Experimental desig for a air variable capacitor. I tried covering the fins with copper foil, but every small wrinkle causes arcing. ... Need more tinkering :-)

... to fit my specific SHCS, so it may not fit yours. It has a little 6mm hexagon inside to lock it into the bolt head. I uploaded both a bottom mount and a panel mount version. I may post a version for air variable capacitors when I get some. ...

... of the bolt. I made a bottom mount, and a panel mount version. Both have 4mm bolt holes. My variable capacitors use 2.5mm bolts, yours may be different. I will likely make a version for air variable capacitors soon, as I have some in the mail.

variable capacitor for old school radio design

This is a variable capacitor, by turning the vertical axle you can change how much the plates overlap, changing the capacitance of the device.

A variable capacitor is an electrical component that can be adjusted to alter its capacitance, enabling the user to control or tune various electronic devices and circuits. ...By changing the distance or overlapping area between its plates, a variable...

Old school looking (ish) variable capacitor. ...My super ultra cheap Part Tester/LCR meter (probably not at all accurate) gives me a capacitance range of about 25pf to 130pf.

A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically.Dear Guest! If you download this model, hit "like". ...Enjoy :-)I will also be grateful if you give me an idea of a new project you need.

A mostly-printed variable capacitor. I don't necessarily recommend making this one, as I designed it around what I had, and it isn't perfect. This is more sharing for inspirational purposes :) Uses two 100mmx70mm single-sided copper clad...

Variable Capacitor Knob for China HF antenna tuner kit.

Create Your Own Unique Butterfly Variable Capacitor, as these are now difficult to obtain.

This is a dial for the Varicon capacitor on my tuner. ... On eBay: Variable Capacitor Polyvaricon x10 with Mounting Screws for QRP ATU, VFO, Receiver

This is a 3D printed butterfly type variable capacitor. Can be extended to any length/capacity by just adding more plates. Distance between rotor and stator plates is ~ 2.5mm. Currently contain only 3 plates for the rotor and 4 sets for the stator.

I needed to upgrade those low-cost Chinese variable capacitors to make them more useful in my radio projects. So, here's what I came up with. You can extend the shaft to your desired length. It fits perfectly on my collection of VCs from China and...

I still need to install the plates themselves for testing of the capacitance yet.*** A variable capacitor designed to approximate 10-120pF in value. At this point, it's purely mathematical as I haven't printed it yet. It's intended to utilize two...

You need a capacitor, like the kind found in cans, that's got a capacity ranging from twenty to seventy picofarads. ...Here are the things you're gonna need to make one: * Fifty millimeter-wide adhesive copper foil * Some tiny wires to go with it ...

Remix of "Air Gap Capacitor System"

A capacitor labelled as Air Capacitor 158-6 is what's being referred to in this context.

Air gap capacitors are so very expensive, so I make my own. This is two end brackets, one set of spacers for anode and cathode, a stencil of anode and cathode plates, and an alignment tool. Most likely best printed in ABS, ASA, or PETG; PLA is just...

I made this variable capacitor as CV trimmer for my magloop antenna project, combined with fixed capacitor made in bakelite pcb. ...It works well for low power transmitting (5 - 10 watt).

This is OpenSCAD high voltage sliding variable capacitor generator. It allows you to specify number of plates, plate size, distance, sliding gap, etc. To be used inside magnetic loop antenna or antenna tuner. This is based on my positive experience...

This component fits perfectly onto the drive shaft of my vacuum variable capacitor. The shaft itself measures approximately 12.6 millimeters in diameter - the bore in this part is precisely 12.75 millimeters. Furthermore, there's a crossbar running...
