vacuum variable capacitor 3d models

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...

I have a model of a 10 kV vacuum variable capacitor that ranges from 0 to 300 pF. It's labeled with C.M.C-147-684, which could be its model number. Other than the voltage rating, there are no other markings on it. I think it was listed as a...

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...

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

China HF Antenna Tuner Kit Requires a Versatile Variable Capacitor Knob.

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

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

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

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

Insulator_C-V100P Insulating collar for Antique Electronics Supply 100pF variable capacitor. ...This collar fits between the capacitor and the panel, ensuring that the metal collar at the shaft cannot make contact with the panel or any burrs from...

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 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...

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...

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 ...

Designed to clamp a KP1-4 5-100pF 25kV variable vacuum capacitor together with the 28mm diameter ends of the copper tube from the magnetic loop antenna, this bracket is a clever solution. ...The contacts of the capacitor are 52mm in diameter, and the...

It should fit most of those little plastic variable capacitors. All the ones I've found had the same shaft size and shape. You'll need some short 2.5mm bolts for the capacitor. If they're too long they'll short out the capacitor. The knob was...

... 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.

These are the vacuum tubes that I modeled when building my replica Flux Capacitor. ...I printed them out on an Elegoo Saturn in clear.

This clamp is specifically designed to hold a Russian vacuum capacitor firmly in place on 16mm copper tubing for the purpose of creating a magnetic loop antenna. The large central hole measures exactly 52mm in diameter, providing ample clearance for...

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).

One bracket supports mounting the variable capacitor lugs down, lugs left, or lugs right (with protective top cover. The other bracket supports mounting the variable capacitor with the lugs up, lugs left, and lugs right, but not down.WARNING. Watch...

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...

I used original props consisting of three high voltage Torr vacuum relays to create the Flux capacitor design. Since I didn't have the opportunity to hold an original in my hand, this design is based on measurements taken by others that were...
