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 and other hot topics.
All circuits and ideas are of my own design or a variance of others and
