Collaborate Disseminate
With the Great Chip Shortage still delaying deliveries of new components, now might be a good time to look around your lab and inspect those piles of chips that you …read more Continue reading Hackaday Prize 2022: Reuse Those DIP Chips to Make a 1980s-Style Single-Board Computer
Over the years we’ve seen a number of hackers generate VGA with 74xx logic chips, but they’ve generally not been the most practical of builds. Often put together as part …read more Continue reading A Slim 7400 Logic VGA Board For All Your Retro Needs
Building your own computer has many possible paths. One can fabricate their own Z80 or Motorola 6502 computers and then run a period correct OS. Or a person could start …read more Continue reading Homebrew 16 Bit Computer Reinvents All The Wheels
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 …read more Continue reading SPAM-1 is a Well-Documented Discrete CPU With an Impressive Software Library
In a world with software-defined radios and single-chip receivers, a superheterodyne shortwave radio might not exactly score high on the pizzazz scale. After all, people have been mixing, filtering, and …read more Continue reading A Superheterodyne Receiver with a 74xx Twist
We see a lot of discrete-logic computer builds these days, and we love them all. But after a while, they kind of all blend in with each other. So what’s the discrete logic aficionado to do if they want to stand out from the pack? Perhaps this CPU-less computer with …read more

Where do you go if you want crazy old electronic crap? If you’re thinking a ham swap meet is the best place, think again. [Fran] got the opportunity to clean out the storage closet for the physics department at the University of Pennsylvania. Oh, man is there some cool stuff here. This room was filled to the brim with old databooks and development boards, and a sample kit for the unobtanium Nimo tube.
The Gigatron is a Hackaday Prize entry to build a multi-Megahertz computer with a color display out of TTL logic. Now, all this work is finally paying …read more
