Simple Breadboard SDR For Shortwave

One of the best ways to learn about radios is to build your own, even in the age of cheap SDR dongles. [Aniss Oulhaci] demonstrates this with a simple HF SDR receiver built on a breadboard. The rec…

Retro Breadboard Gives Up Its 1960s Secrets

When we see [Ken Shirriff] reverse engineering something, it tends to be on the microscopic level. His usual forte is looking at die photos of strange and obsolete chips and figuring out how they w…

555 Timer Contest Entry: A Digital Counter With Nothing But 555s

With a 555 on the BOM, you never know what you’re going to get. With 40 of the versatile timer chips in a build, you might just get something completely unexpected, like this 555-based eight-…

A Well Documented BreadBoard Computer Shows Dedication

These pages have not been exactly devoid of home-built computers, with those constructed on solderless breadboard less frequent, but still not rarities. But what is more of a rarity is this ground-…

SPAM-1 Is A Well-Documented Discrete CPU With An Impressive Software Library

Here at Hackaday we love projects that are so well-documented that you can spend days reading up on what the designer has achieved. [John Lonergan] didn’t disappoint when he designed the SPAM…

BreadBin Is An 8-bit TTL CPU On A Breadboard, In A Bread Bin

Building a CPU out of logic gates is a great way to learn about the inner workings of microprocessors, and we’ve seen several impressive projects in this area. [c0pperdragon] set himself the …

3D-Printed, Hot-Swap Keyboard PCB Generator Is Super Cool

About a month ago, [50an6xy06r6n] shared their hot swap 3D-printed circuit board for keyboard design with the mechanical keyboard subreddit. It’s more of a prototyping tool than a permanent f…

Silicon Jumpers Make This Wire-Free Breadboard Programmable

There’s no doubting the utility of the trusty solderless breadboard, but you have to admit they’re less than perfect. They’re not ideal for certain types of circuits, of course, b…
