Last week I completed the SAO flower badge redrawing task, making a complete KiCad project. Most of the SAO petals are already released as KiCad projects, except for the Petal …read more Continue reading Supercon 2024 SAO Petal KiCad Redrawing Project
Out of curiosity, I redrew the Supercon Vectorscope badge schematics in KiCad last year. As you might suspect, going from PCB to schematic is opposite to the normal design flow …read more Continue reading Supercon 2024 Flower SAO Badge Redrawing in KiCad
When I was growing up, about 4 or 5 years old, I had an unorthodox favourite type of reading material: service manuals for my dad’s audio equipment. This got to …read more Continue reading Hack All The Things, Get All The Schematics
The mobile phone is an expensive and often surprisingly fragile device, whose manufacturers are notorious for making them as difficult to repair as possible. Glued-together cases and unreplaceable batteries abound, …read more Continue reading Schematics, For A Modern Flagship Phone
When I saw this year’s Supercon Vectorscope badge, I decided that I had to build one for myself. Since I couldn’t attend in-person, I immediately got the PCBs and parts …read more Continue reading Vectorscope KiCad Redrawing Project
Before the days of MP3 players and smartphones, and even before portable CD players, those of us of a certain age remember that our cassette players were about the only …read more Continue reading Pocket Radio Powered By Tiny Microcontroller
With the widespread adoption of emulators, almost anyone can start playing video games from bygone eras. Some systems are even capable of supporting homebrew games, with several having active communities …read more Continue reading Reverse Engineering the SEGA Mega Drive
We wondered recently about those crude ASCII schematics you see in some documentation — are there any dedicated schematic-focused tools to draw them, or are they just hand-crafted using various …read more Continue reading ASCII Schematic Diagrams
Some projects are a rite of passage within their respected fields. For computer science, building one’s own computer from scratch is certainly among those projects. Of course, we’re not talking about buying components online and snapping together a modern x86 machine. We mean building something closer to a fully-programmable 8-bit …read more
We often lament that the days of repairable electronics are long gone. It used to be you’d get schematics for a piece of gear, and you could just as easily crack it open and fix something as the local repairman — assuming you had the knowledge and tools. But today, everything is built to be thrown away when something goes wrong, and you might as well check at the end of a rainbow if you’re searching for a circuit diagram for a new piece of consumer electronics.
But [Robson] writes in with an interesting story that gives us hope that …read more
