High-Speed Pocket Hot Dog Cooker

https://invidious.privacyredirect.com/watch?v=0-OKW5CsKkU

Few of us complain that hot dogs take too long to cook, because we buy them from a stand. Still, if you do have to make your own dog, it can be a frustrating problem. To solve this issue, [Joel Creates] whipped up a solution to cook hot dogs nearly instantaneously. What’s more, it even fits in your pocket!

The idea behind this build is the same as the classic Presto hot dog cooker—pass electricity through a hot dog frank, and it’ll heat up just like any other resistive heating element. To achieve this, [Joel] hooked up a lithium-polymer pack to...

Christmas Ornament Has Hidden Compartment, Clever Design

https://invidious.privacyredirect.com/watch?v=Oyy16lbpe_c

If you need something clever for a gift, consider this two-part 3D-printed Christmas ornament that has a small secret compartment. But there’s a catch: the print is a challenging one. So make sure your printer is up to the task before you begin (or just mash PRINT and find out).

This design is from [Angus] of [Maker’s Muse] and it’s not just eye-catching, but meticulously designed specifically for 3D printing. In fact, [Angus]’s video (embedded under the page break) is a great...

Calibrating a Printer with Computer Vision and Precise Timing

https://invidious.privacyredirect.com/watch?v=8DvygwWloCc

[Dennis] of [Made by Dennis] has been building a Voron 0 for fun and education, and since this apparently wasn’t enough of a challenge, decided to add a number of scratch-built improvements and modifications along the way. In his latest video on the journey, he rigorously calibrated the printer’s motion system, including translation distances, the perpendicularity of the axes, and the bed’s position. The goal was to get better than 100-micrometer precision over a 100 mm range, and reaching this required detours into computer vision, clock synchronization, and linear algebra.

To correct for non-perpendicular or distorted axes, [Dennis] calculated a position...

Ask Hackaday: What Goes Into A Legible Font, And Why Does It Matter?

American and British patents, for comparison.

There’s an interesting cultural observation to be made as a writer based in Europe, that we like our sans-serif fonts, while our American friends seem to prefer a font with a serif. It’s something that was particularly noticeable in the days of print advertising, and it becomes very obvious when looking at government documents.

We’ve brought together two 1980s patents from the respective sources to illustrate this, the American RSA encryption patent, and the British drive circuitry patent for the Sinclair flat screen CRT. The American one uses Times New Roman, while the British one uses...

NIST was 5 μs off UTC after last week's power cut

NIST was 5 μs off UTC after last week's power cut

If you were 5 microseconds late today, blame it on NIST.

Their facility in Boulder Colorado just had its power cut for multiple days. After a backup generator failed, their main ensemble clock lost track of UTC, or Universal Time Coordinated.

But even if you used the NTP timing servers they run, they were never off by more than 5 microseconds.

5 μs might seem insignificant. But it is significant for scientists and universities who rely on NIST's more specialized timing...

ESP-Scope is a web-based oscilloscope built using the ESP-IDF framework and Gemini 3 LLM

ESP-Scope is an open-source firmware transforming any ESP32 board into an oscilloscope using one of the ADC pins up to 83,333 Hz sample rate (on the ESP32-C6) and visualizing the results over Wi-Fi in a web browser, be it Google Chrome, Mozilla Firefox, or others. It’s not the first ESP32 oscilloscope project we’ve seen, as last year, we covered Bojan Jurca’s “Esp32_oscilloscope” Arduino sketch doing something very similar. The ESP-Scope is a little different, since it’s based on the ESP-IDF framework, and was used to test AI code generators, specifically “Google Antigravity using Gemini 3, with refinements, hints and tips...
