How to make an adjustable capacitor
Adjustable Timer Circuit Using IC 555
The produced time delay is fully adjustable and the user has the freedom to set the time period as desired. There are many ways of making simple timer circuits using different ICs and discrete components; here I have explained one such circuit using the ubiquitous IC 555.

1 – 1µF capacitor. All of these parts can be found at Radio Shack or similar online websites that sell such components, and the job of wiring is very simple and straightforward. First find your signal wire and ground wire, cut them and splice them leaving a good inch of exposed wire for you to wire your component inline.
Variable Capacitors: Tuning and Adjusting
Adjustable capacitance makes these capacitors essential for fine-tuning electronic circuits. In electronic applications like radios and oscillators, their ability to adjust capacitance by …
VARIABLE CAPACITOR BASICS
VARIABLE CAPACITOR BASICS A variable capacitor is a capacitor whose capacitance may be intentionally and repeatedly changed mechanically or electronically. Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore they are sometimes called tuning capacitors), or as a variable reactance, e.g. …

DIY Variable Capacitor for Homemade AM Radio Receiver
In summary, for a homemade AM radio receiver, the best options for a variable capacitor are either a parallel plate capacitor with one adjustable plate or a coaxial capacitor with a rod inside a tube. The position of the adjustable plate or rod can be adjusted with a screw. It may be tricky to achieve values higher than a couple of tens of …
Electronic 12V DC Capacitive Discharge Ignition (CDI) Circuits
Here, the left side stage which includes the IC 555, 4 transistors and the X1 transformer, form a 12 V to 500 V step up push pull inverter. The right side section using the SCR BT151, and the associated circuitry forms the capacitive discharge ignition stage.
identification
Yes, it is an adjustable capacitor. Each capacitor ''plate'' is usually a stack of vanes, with a gap between each vane. A vane looks like slightly less than half a disc, mounted on the central shaft. One ''plate'' stack is fixed, the other is rotated by the adjustment shaft. This moves the stacks of vanes in between each other.
Types of Capacitors: Definition, Diagram, Working, …
Adjustable Capacitors; Variable Capacitors; Fixed Capacitors. The capacitors whose capacitance value is fixed are known as fixed capacitors. Fixed Capacitors Symbol. Ex: Mica capacitor, paper …
Make Your Own High-Voltage Capacitors
Plastic cases for dry capacitors are easy to make with acrylic sheets glued at all corners with Silicone RTV. Oil-proof cases can be made for immersed models, but you will need to rough-up the plastic at the sealing edges with sandpaper and use both a bonding and second fillet glue coating for a liquid-proof seal. Metal cases can be made from ...

High Voltage Butterfly Capacitor for Loop Antennas
That''s why they use capacitors in series. The pro for series''s capacitors is that the voltage rating is doubled. The anti is that the value of capacitance is divided by 2. For the split stator capacitor the 2 capacitors are connected in series by the shaft (blue) and the red spots on the first drawing are losses.

A variable capacitor is designed to have adjustable capacitance. It typically consists of two sets of metal plates that are insulated from each other. One set of plates remains fixed, known as the stator, while the other set is movable, known as the rotor. The capacitance of the variable capacitor can be adjusted by changing the position of …
