We always look forward to [Stefan’s] CNC Kitchen videos. They are usually useful, but always carefully thought out and backed with experimental data. His latest is about creating transparent and …read more Continue reading Full Transparency: Stronger FDM Prints
Mathematical transforms can be a great help in understanding signals. Imaging trying to look at a complex waveform and figuring out the frequency components without the Fourier transform. [Artem Kirsanov] …read more Continue reading Understanding Wavelets
We will admit to not being particularly artistic, but we do remember an art teacher telling us that sometimes it is better to draw what isn’t there instead of what’s …read more Continue reading Diff Tool Knows What You Mean
We think of the Internet extending to small devices as a modern trend, but it actually is a good example of how everything makes a circle. Today, we want the …read more Continue reading The Internet Without the Computer: 1990s Style
If you have any sort of device that cuts like a CNC mill or a laser cutter, you probably generate a lot of strange-looking scrap material. Most of us hate …read more Continue reading Upcycling Flat Scraps with Open Source Tools
The advent of cheap software-defined radio hardware means that what would have once been an exotic expensive undertaking can now be relatively cheap. [David] notes that using some pretty simple …read more Continue reading Tracking Weather Balloons with SDR
We’ve all been there. Something that is known to work doesn’t work out in the field. But back at home base, it works fine. How do you fix it? Of …read more Continue reading Troubleshooting Barcodes: A Lesson in Critical Thinking
Most of us strip the insulation off wires using some form of metal blade or blades. You can get many tools that do that, but you can also get by …read more Continue reading Ask Hackaday: Stripping Wires with Lasers
We always enjoy the odd things that people do to try to get better audio reproduction. Exotic cables, special amplifiers, and higher resolution digitization come to mind. Most of this …read more Continue reading Improve CD Sound by Shaving?
In the old days, if you wanted to snoop on a piece of serial gear, you probably had a serial monitor or, perhaps, an attachment for your scope or logic …read more Continue reading Linux Fu: Eavesdropping on Serial
