As I mentioned in my recent columns on the topic of adding pull-up or pull-down resistors to the inputs of unused or partially used logic gates and functions (see Part 1, Part 2, and Part 3), I was ...

Over the last year, the production of homebrew electronic badges for conferences has exploded. This is badgelife — the creation of custom hardware, a trial by fire of manufacturing, and a mountain of ...

Breadboard CPUs are a fantastic learning experience and require serious dedication and patience. Occasionally, CPU builders eschew their breadboards and fab their design onto a PCB. But this takes ...

Back in the late 1960's, I experimented with DTL. That's not a misprint. DTL stands for diode-transistor logic and it was popular in “930-series” logic devices. I used wire-wrap or point-to-point ...

CWAV has combined a prototype plug-in breadboard with their USB-based test equipment and tossed in a handful of parts to give you a prototyping station. This would be great for learning electronics ...

Well, I must admit to being flabbergasted. I think I can say without fear of contradiction that my “flabber” has rarely been so “gasted.” The cause of my current state-of-gast was the rapturously ...
