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

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

IoT Device Pulls Its Weight in Home Brewing

Brewing beer or making wine at home isn’t complicated but it does require an attention to detail and a willingness to measure and sanitize things multiple times, particularly when tracking the progress of fermentation. This job has gotten easier thanks to the iSpindel project; an ESP8266 based IoT device intended as a DIY alternative to a costly commercial solution.

Tracking fermentation normally involves a simple yet critical piece of equipment called a hydrometer (shown left), which measures the specific gravity or relative density of a liquid. A hydrometer is used by winemakers and brewers to determine how much sugar remains …read more
