About the VoltageSensing PCB

VoltageSensing is an open source PCB design by gongminmin, published on GitHub under the MIT license. It is a 2-layer board measuring 40.6 × 27.9 mm, with 22 components from 11 distinct parts.

Other key parts include the LM393 and PC817. By type, the board carries 11 resistors, 4 diodes, 3 ICs, 2 connectors, 1 battery holder and 1 capacitor.

From the project

A preliminary design of a plasma engine for spacecraft propulsion

In Star Trek universe, impulse drive is a propulsion system of spacecrafts for interplanetary travel. This project is trying to design a real-world impulse drive. The basic characteristics of this engine are

Electric propulsion Large thrust Long specific impulse No or little moving parts Good scalability Low cost

We'd like to make it easy to implement, so people can build it as a hobby project.
