Arduino and the Other Kind of Homebrew

Usually, when we are talking about homebrew around here, we mean building your own equipment. However, most other people probably mean brewing beer, something that’s become increasingly popular as one goes from microbreweries to home kitchen breweries. People have been making beer for centuries so you can imagine it doesn’t take sophisticated equipment, but a little automation can go a long way to making it easier. When [LeapingLamb] made a batch using only a cooler, a stock pot, and a propane burner, he knew he had to do something better. That’s how Brew|LOGIC was born.

There are many ways to …read more

Nintendo 64 Homebrew Via Game Shark

The Nintendo 64 is a classic console now, and much loved, despite losing in commercial stakes to the dominating PlayStation from Sony. It’s one that doesn’t always get as much attention in the homebrew and hacker scene, compared to platforms like the NES and Game Boy. This means the tools required to work with the console aren’t as well-known. However, there’s a remarkably easy way to load homebrew on to the Nintendo 64, if you’ve got the right hardware.

To pull this off, you’ll need a N64 Gameshark, particularly a version higher than 3.0. These included a parallel port and …read more

A Low Cost VR Headset

Virtual reality systems have been at the forefront of development for several decades. While there are  commercial offerings now, it’s interesting to go back in time to when the systems were much more limited. [Colin Ord] recently completed his own VR system, modeled on available systems from 20-30 years ago, which gives us a look inside what those systems would have been like, as well as being built for a very low cost using today’s technology.

The core of this project is a head tracker, which uses two BBC Microbits as they have both the accelerometer and compass needed to …read more

The Math That Makes Computers Go, Built On a Tiny PCB

A computer is, at its core, just a bunch of transistors wired together. Once you have enough transistors on a board, though, one of the first layers of abstraction that arises is the Arithmetic Logic Unit. The ALU takes in two sets of data, performs a chosen math function, and outputs one data set as the result. It really is the core of what makes computers compute.

An ALU is built into modern processors, but that wasn’t always how it was done. If you’re looking to build a recreation of an early computer you may need a standalone, and that’s …read more

Scribble Your Way To Quick Printed Circuit Boards

There are a variety of techniques employed by electronic constructors seeking the convenience of a printed circuit board without the inconvenience of making a printed circuit board. Dead bug style construction in which the components float on a spiders-web of soldered leads above a ground plane is one, Manhattan style construction in which pads made from small cut squares of bare copper-clad PCB are glued on top of a groundplane is another.

[Freestate QRP] has another take on this type of electronics, with what he calls “Scribble style” construction. He cuts away copper from bare board to create pads and …read more
