Introduction

Many projects require a negative voltage source such as those heavily based around op-amps and generating a negative voltage can be difficult. In this kit you will learn how to build a simple negative voltage generator that can be useful in scenarios where a negative voltage is needed from a single rail supply such as a battery or solar panel! This kit is also great for solder practice and teaches how capacitive coupling can be exploited in electronic circuits.

What makes this special?

MitchElectronics kits are designed with education in mind and as such use high quality double sided PCBs. The through-hole plating of each pad means that even the most novice of builders will not be able to tear traces or break pads (unlike many other professional kits which only use single sided boards to save costs). These kits are also RoHS compliant which make them safe to use and no kits use non-RoHS components such as LDRs (which contain Cadmium).
