[Indeterminate Design] tried to 3D print a screw compressor some time ago but wasn’t satisfied with the result. He’s trying it again, and you can check it out in the …read more Continue reading 3D Printed Screw Compressor Revisited
AM radios were easy to understand. The strength of the signal goes up and down, and the audio follows. FM radio is a little more difficult. [AllAmericanFiveRadio] has an old …read more Continue reading FM Radio is Discriminating
[Technistuff] read a paper about simulating a “minimal” cell — apparently a cell with only 493 genes. This led to a goal: reproduce the simulation in TypeScript so it can …read more Continue reading Simulating Cellular Biology in the Browser
We’ve often said you can make a logic gate out of darn near anything. [The Action Lab] agrees and just released a video showing how he made some logic gates …read more Continue reading Computer Logic Spins with No Electricity
While the 8080 started the personal computer revolution, the Z80 was quickly a winner because it was easier to use and had more capabilities. [Noel] found out though that the …read more Continue reading Z80 I/O Madness
You probably see a frit every day and don’t even notice it. What is it? You know the black band around your car’s windshield? That’s a frit (which, by the …read more Continue reading Tech in Plain Sight: Windshield Frit
[Lost in Tech] set out to examine a variety of 3D printing nozzles. Before he got there, though, he found some issues. In particular, he found that his current crop …read more Continue reading Deep Dive into 3D Printing Nozzles
There’s an upcoming movie, Argyle, about an author whose spy novels are a little too accurate, and she becomes a target of a real-life spy game. We haven’t seen the …read more Continue reading Predicting the A-Bomb: The Cartmill Affair
The Rigol DHO800 and DHO900 series use Android underneath, and as you might expect, this makes them easier to hack. A case in point: [VoltLog] demonstrates that you can add …read more Continue reading Android-Powered Rigol Scopes Go Wireless
While simulating an Arduino isn’t a new idea, a recent project by [LRusso] provides an open source JavaScript simulator that runs in your browser. You can try it out live …read more Continue reading Arduino, Virtually
