For today’s podcast Elliot Williams is joined by Jenny List, and we’re pushing the limits of mobile connectivity as Jenny’s coming to us from a North Sea ferry. We start by looking forward to the upcoming Hackaday Europe, with a new location in Lecco, Italy. We hope you can join us there! There’s a bumper […]
Magnet placement tools are great because they remove finger fumbling while ensuring correct polarity every time. [EmGi] has made a further improvement by making a version that auto-feeds from an internal stack of magnets. A stack of magnets auto-feeds with every press of the plunger. That is a trickier task than one might imagine, because […]
There was a period from the 1970s to the mid-2000s or so when a fixture underneath the family TV set was a VHS videocassette recorder. These were a masterpiece of cramming a color video signal into the restricted bandwidth of an affordable 1970s helical-scan tape deck, which was achieved by clever use of frequency shifting […]
During the Cold War, the specter of a nuclear “dead man’s switch” was central to the concept of Mutually Assured Destruction (MAD). In the event that one side was annihilated by the other, an automated system would be triggered to deliver a revenge strike that would ultimately destroy the attacker. It was the ultimate defense, […]
A few months back, Sandia National Laboratories announced they had acquired a new supercomputer. It wasn’t the biggest, but it still offered in their eyes something unique. This particular supercomputer contains NextSilicon’s much-hyped Maverick-2 ‘dataflow accelerator’ chips. Targeting the high-performance computing (HPC) market, these chips are claimed to hold a 10x advantage over the best […]
A modern computer can be a great productivity tool. It can also be a great source of distractions. To solve that issue, [Quackieduckie] built the e-typer—a device for writing without distraction. [Quackieduckie] refers to the device as a “low-cost e-ink typewriter” which lays out the basic mode of operation. It consists of a 4.2 inch […]
As anyone who’s made a thing knows, a lot of work goes into bringing something from idea to completion. But there’s also considerable satisfaction in the process. [Willian] recently did exactly that, and shares the joyful experience of creating a homebrew handheld game gadget from scratch. It runs a homebrewed Tetris clone (as well as […]
It’s becoming somewhat of a theme that machine-generated content – whether it’s code, text or graphics – keeps pushing people to their limits, mostly by how such ‘AI slop’ is generally of outrageously poor quality, but as in the case of [Vincent Driessen] there’s also a clear copyright infringement angle involved. Recently he found that […]
The RF section of the ESP32-C6 die. (Credit: electronupdate, YouTube) With the ESP32-P4 not having any wireless functionality and instead focusing on being a small SoC, it makes sense to combine it with a second chip that handles features like WiFi and Bluetooth. This makes the Guition ESP32-P4-M3 module both a pretty good example of […]
When you’re livestreaming, it can be tempting to fire off all kinds of wacky sound effects like you’re a morning radio DJ back in the heady days of 1995. If that’s who you want to be, you might like this soundboard project from [Biker Glen]. The build is based around an RP2040 microcontroller. It’s paired […]
