It all began for me around 1981/82 when I built an electronic musical doorbell kit for my sister. It has been in use in two different... Continue Reading →

The issue of bounce with them is significant and for years I’ve been looking a reliable method of dealing with it. I thought I had it figured out by either... Continue Reading →
