[Rajendra] got tired of building the same basic circuits time and again on the breadboard. He decided to build some simple, modular circuits on protoboard and make them easy to interface with the ...

Here’s the most amazing 8-bit DIY computer implemented using a bunch of simple logic chips — along with a cornucopia of flashing LEDs — mounted on a cluster of breadboards. I stand in awe. As I’ve ...

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 ...

Regular Hackaday readers will be familiar with all the cool things you can do with FPGAs; emulating old video game consoles, cracking encryption protocols, and DIY logic analyzers become relatively ...

Words such as breadboard and prototype have an almost romantic allure in the electrical engineering world. Although the terms are sometimes used interchangeably, they are somewhat different: a ...
