Neat Circuits

This site is always Under Construction

This is a website devoted to all kinds of neat pictures, designs, circuits, ideas and suggestions. Much of the info found on this site are my tutorials, How to's, opinions and suggestions. Although some of the topics and circuits may seem simple and basic, it is primarily for the newcomers and beginners in electronics.

All circuits and ideas are of my own design or a variance of others and are copyright by myself and not to be copied, sold or used commercially without my express written consent. However I encourage anyone to reference the pages on this site.
