We all know, at least intellectually, that our computers are all built with lots of tiny transistors. But beyond that it’s a little hard to describe. They’re printed on a …read more Continue reading CPU Built From Discrete Transistors

Pick and place machines are a wonder to behold, as they delicately and accurately place part after part. Unfortunately, they have to have a similarly wondrous price tag. Luckily, they …read more Continue reading An RP2040 Powered Pick And Place
[MakingDevices] has created a simple stopwatch that makes for a nice introduction to surface mount electronic design and assembly. The project is open source hardware (OSHW) certified, with Gerbers, KiCAD …read more Continue reading Add an OSHW Certified Stopwatch to Your Toolkit
Teardowns of cheap electronic devices can produce results that are interesting, horrifying, or both, especially when mains power is involved. [bigclivedotcom] gave a minimalist LED lamp his reverse engineering treatment, …read more Continue reading Investigating A New Chip In A Minimalist LED Lamp
Mihir Shah has designed many a PCB in his time. However, when working through the development process, he grew tired of the messy, antiquated methods of communicating design data with his team. Annotating photos is slow and cumbersome, while sending board design files requires everyone to use the same software …read more
One thing that always means the end of the year is close is the reappearance of TV ads for “The Clapper.” After all, who needs home automation when you can clap on and clap off? While we’re partial to our usual home automation solutions, [Utsource123] shows us that building a …read more
Don’t get me wrong. Like most people, there’s nothing I enjoy more than solving a long, involved math problem by hand. But, sometimes, a few pages of algebraic scratches on paper is just a means to an end. I find this especially true during electronic design sessions, be it circuit …read more
This is some of the prettiest and easiest biohacking we’ve seen yet. Continue reading This Pretty Temporary Tattoo Lets You Remotely Control Your Devices
We return once again to the work of Dr. Claude E. Shannon, this time to his Masters thesis on relay switching circuit design. This thesis introduced switching algebra that allows the systematic design and optimization of logical circuits. While Shannon’s work applied to switches and relays, it is equally applicable to all the modern forms of digital circuits. His thesis received widespread notice when published as “A Symbolic Analysis of Relay and Switching Circuits” in 1938. This work built on the Boolean algebra developed by George Boole and an analysis of logic by Augustus De Morgan which these mathematicians published …read more
