High-Q Coil Construction Techniques
High-Q coil inductors have something in common: the length of the coil can only be slightly longer than its diameter. In other words, high-Q coils have cube-like dimensions

Homebrew Your Own Inductors
Air-dielectric inductors can be made quite easily at home

Helical Coil
The inductance and self capacitance of a helical coil can be determined by entering its dimensions in the boxes above. The length of wire used is also calculated

Jar Capacitance Calculator For Coils
This calculator requires the use of Javascript enabled and capable browsers. The purpose of the calculator is to determine the capacitance value of the jar capacitor needed for the circuit's coil
