Sometimes the most useful hacks are also the simplest ones. A case in point is the LED and resistor assembly that [Skippy] recently posted on his blog. The idea is to solder up some pre-made ...

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 ...

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 ...

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.

This breadboard module is made to cater a PIC16F628A microcontroller for faster prototyping of circuits and avoid the initial microcontroller setup. This breadboard module is made to cater a ...

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, ...

Electronic enthusiasts or those looking to learn how to build electronic circuits may be interested in a small, portable yet fully functional open source OLED breadboard power supply. The ANT BBPS ...

Microaware’s Sandwizz, a schematic-configurable breadboard, hit 120% of its funding goal on Kickstarter on July 19, 2024. The KiCad freeware schematic capture tool is used to configure an active ...

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 ...

Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides clear results in just seconds. For related tutorials and step-by-step build ...
