Building a computer around a TTL CPU

[Bill's] worked on his homebrew computer for almost a decade. He didn’t start with a Z80 processor like a lot of the projects we’ve seen, but instead build the CPU itself from 74-series TTL chips and a ridiculous amount of wire wrapping to connect it all.

The video after the break shows off the functionality. We love the front panel, … Read the rest

Homebrew TTL logic computer

Although [Jack] just graduated High School and doesn’t have much experience with electronics, that didn’t stop him from building the DUO Adept, a homebrew computer built entirely out of TTL logic chips.

The DUO Adept has 64k of memory, 6K of which is dedicated to the video ram that outputs a 240×208 black and white image onto a TV. Bootstrapping … Read the rest

[Stan] was putting together his nano-brewery, and while waiting for his beer to finish fermenting, he decided to work on the storage portion of his project.

Weather station turned data logger

Home brewing the perfect beer (or root beer in this case) requires a watchful eye and stable temperature, but [Gregory] has a house that is 120 years old. While we are sure it is a beautiful home, it does have its usual historical issues including temperature fluctuations.

[Gregory] suspects this to be the reason why his root beer is not … Read the rest

PSP homebrew using the Half-Byte Loader

[Rich] tipped us off about the Half-Byte Loader which lets you run homebrew on late-model Sony PlayStation Portables. Above you can see a PSP Go running Doom (a screenshot from the video after the break), which is a prerequisite for any cracked device. HBL uses an exploit in the game demo of Patapon 2, which is free for download. A … Read the rest

USB gameboy cart

[Jose Torres] sent in his latest attempt at creating a custom Gameboy game cartridge. We’ve featured his projects before, and he’s come a lot closer over the last 2 years. He’s aiming to create an easy interface for homebrewers that doesn’t require any other special equipment. In this revision, he’s using a PIC and a memory controller to interface between … Read the rest
