An Atari Graphics Chip, Ready For You To Build

The most notable of the home computer and console hardware from the 8-bit golden era didn’t get their impressive sound and graphics from off-the-shelf silicon, instead they relied on secretive custom chipsets to get the edge over their competitors. Unfortunately for vintage gaming aficionados, those chips are now long out …read more

Byte Sized Pieces Help The KiCad Go Down

It’s no surprise that we here at Hackaday are big fans of Fritzing KiCad. But to a beginner (or a seasoned veteran!) the learning curve can be cliff-like in its severity. In 2016 we published a piece linking to project by friend-of-the-Hackaday [Chris Gammell] called Contextual Electronics, his project to …read more

Ask Hackaday: How Do You Draw Schematics?

The lingua franca of electronic design is the schematic. I can pick up a datasheet written in Chinese (a language I do not read or speak) and usually get a half-decent idea of what the part is all about from the drawings. Unfortunately, even as my design experience has grown …read more

What’s Coming In KiCad Version 5

Way back in the day, at least five years ago, if you wanted to design a printed circuit board your best option was Eagle. Now, Eagle is an Autodesk property, the licensing model has changed (although there’s still a free version, people) and the Open Source EDA suite KiCad is getting better and better. New developers are contributing to the project, and by some measures, KiCad is now the most popular tool to develop Open Source hardware.

At FOSDEM last week, [Wayne Stambaugh], project lead of KiCad laid out what features are due in the upcoming release of version 5. …read more

Making an Arduino Shield PCB with Fritzing

[Allan Schwartz] decided to document his experience using Fritzing to design, fabricate, and test a custom Arduino shield PCB, and his step-by-step documentation makes the workflow very clear. Anyone who is curious or has been looking for an opportunity to get started will find [Allan]’s process useful to follow. The PCB in question has two shift registers, eight LEDs, eight buttons, and fits onto an Arduino; it’s just complex enough to demonstrate useful design features and methods while remaining accessible.

[Allan] starts with a basic breadboard design, draws a schematic, prototypes the circuit, then designs the PCB and orders it …read more
