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 ...

Most Hackaday readers will no doubt at some point used a solderless breadboard for prototyping. They do the job, but sometimes their layout can be inflexible and keeping track of signals can be a pain ...

The Arduino is a great way for hobbyists and pros alike to experiment with programmable objects, but it can be confusing for beginners without these tools.

We will refer to these article collections as “Breadboards,” “Tools,” and “Components” for short. We’re assuming that we are in possession of a full-size breadboard and associated wires (Components, ...

The project is based on LM3915/LM3916 to produce a VU meter with the level indication using 10-segment LED bar graph. The VU meter circuit was built on a breadboard with a few components used such as ...

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 ...

I don’t know about you, but although I like reading about electronics in a theoretical sort of way, there’s nothing I enjoy more than the hands-on building of something and then watching that thing ...
