# Variometer (variable inductor) OpenSCAD generator

## Introduction

![alt text](images/schematics.png)

Allows generation of variometer with various parameters, such as winding wire diameter. Calculates and prints inductance estimation.

Continously tunes from 10uH up to 90uH with default parameters.

Requires dotSCAD library: https://github.com/JustinSDK/dotSCAD, should be cloned into OpenSCAD libraries directory: https://en.wikibooks.org/wiki/OpenSCAD_User_Manual/Libraries.
