A Modern Take on Iconic Industrial Design

Posted on June 9, 2025 by Aaron Beckendorf
Two white, cylindrical speakers are shown. The sides and most of the tops of the speakers are covered in holes, and at the center of the top of each, there is a circular LCD display. The top of the speaker is marked “Braun.”

The Functionalist design philosophy that Dieter Rams brought to Braun from the 50s to the 90s still inspires the look of a few devices, including Apple’s iPod, Teenage Engineer’s synthesizers …read more Continue reading A Modern Take on Iconic Industrial Design→

Simple Triggering for Saleae Logic Analyzers

Posted on June 8, 2025 by Aaron Beckendorf
The Saleae logic analyzer software is shown. One PWM channel is active, with values of 0x0001 displayed above the individual waveforms. On the right panel of the app, a trigger mode configuration panel is open for the simple parallel analyzer.

Saleae logic analyzers seem to have it all: good sampling rates, convenient protocol decoding, and plenty of channels – but not a good way to set rising or falling-edge triggering. …read more Continue reading Simple Triggering for Saleae Logic Analyzers→

Freeze-drying for improved metal printing

Posted on June 6, 2025 by Aaron Beckendorf
A man’s hands are shown in the foreground holding two splines, each with teeth both on the interior and exterior surfaces. Both are identical in shape, but one is larger and made of plastic, and the other is smaller and made of metal.

For all the remarkable improvements we’ve seen in desktop 3D printers, metal printers have tended to stay out of reach for hackers, mostly because they usually rely on precise and …read more Continue reading Freeze-drying for improved metal printing→

Turning the Pluto SDR into a Network Analyzer

Posted on June 5, 2025 by Aaron Beckendorf
The Pluto software-defined radio is placed on a desk, connected by three RF cables to an RF bridge circuit board. The RF bridge has a prominent ballon taking up most of its area.

Usually when we see a project using a software-defined radio (SDR), the SDR’s inputs and outputs are connected to antennae, but [FromConceptToCircuit]’s project connected an ADALM-Pluto SDR to an RF …read more Continue reading Turning the Pluto SDR into a Network Analyzer→

Making solder wick less painful

Posted on June 4, 2025 by Aaron Beckendorf
A circuit board is shown, with the tip of a soldering iron applied to a piece of solder wick positioned above a pad.

For some people (e.g. this author) solder wick is a tool of last resort. Unfortunately, solder suckers and vacuum pumps lose most of their utility when you move from through-hole …read more Continue reading Making solder wick less painful→

A CRT Display for Retro Weather Forecasting

Posted on May 31, 2025 by Aaron Beckendorf
A weather forecast is shown on a blue monochrome cathode ray tube display. It is displaying current conditions, and displays a “The Weather Channel” graphic in the top left corner.

It would be hard to find any electronics still in production which use CRT displays, but for some inscrutable reason it’s easy to find cheap 4-inch CRTs on AliExpress. Not …read more Continue reading A CRT Display for Retro Weather Forecasting→

A Forth OS in 46 Bytes

Posted on May 27, 2025 by Aaron Beckendorf
A console is shown displaying a system’s startup information, followed by “Booting from Hard Disk …”, “Hello World!” in a green font, and “The keyboard is working!”

It’s not often that we can include an operating system in a Hackaday article, but here’s the full 46-byte source of [Philippe Brochard]’s 10biForthOS in 8086 opcodes: 50b8 8e00 31d8 …read more Continue reading A Forth OS in 46 Bytes→

A Quick Introduction to TCP Congestion Control

Posted on May 25, 2025 by Aaron Beckendorf
A graph of download speeds is shown, with two triangular spikes and declines. Above the graph, the label “8 MB/s” is shown.

It’s hard to imagine now, but in the mid-1980s, the Internet came close to collapsing due to the number of users congesting its networks. Computers would request packets as quickly …read more Continue reading A Quick Introduction to TCP Congestion Control→

A Presence-sensing drive for Securely Storing Secrets

Posted on May 24, 2025 by Aaron Beckendorf
A USB dongle is shown connected to a laptop computer. A text box in the lower right corner says "PECKUS is running in DEBUG mode, it is 3x faster in non-DEBUG mode."

When we hear about flash drives in the context of cybersecurity, we tend to think of them more as threats than as targets. When you’re using flash drives to store …read more Continue reading A Presence-sensing drive for Securely Storing Secrets→

Using pitot tubes for more than aircraft

Posted on May 19, 2025 by Aaron Beckendorf
A white control box is shown in the foreground. The box has an LCD display, eight button, and two barbed fittings for flexible tubing.

When we hear the words “pitot tube,” we tend to think more of airplanes than of air ducts, but [Franci Kopač]’s guide to pitot tubes for makers shows that they …read more Continue reading Using pitot tubes for more than aircraft→
