Winner, Name that Ware September 2025
The Ware from September 2025 is a Hotronic AF 75 time base corrector. Really great comment thread, it was fun to read the sleuthing work and thought process behind the guesses. And yah, those SRAM chips make me nostalgic – I remember how expensive those were! Back when 32kiB cost real money.
A couple folks had guessed a time base corrector out of several possibilities, but I like how Guy Dunphy backed his guess up with an explanation of how it works. So, I’ll give Guy the prize this month. Congrats, drop me an email to collect your prize!

Precision Clock Acrylic Case
[Hardware] Smoked acrylic upgrade for the Precision Clock Mk IV
Tiny Continuity Tester
This is a simple continuity tester, based on an ATtiny202, a piezo buzzer, and an LED, for checking circuit wiring or tracing out the tracks on a PCB:
The Tiny Continuity Tester based on an ATtiny202.
The piezo speaker is on the reverse of the board.
It has a low threshold resistance of 50Ω to avoid false positives, and passes less than 0.1mA through the circuit under test, to avoid affecting sensitive components. It's powered from a small button cell, and automatically switches itself off when not in use, avoiding the need for an on/off switch.

Возможно это провал: разгоняем до 400 герц
Стараясь держаться правила — одна статья в неделю — я, с красными глазами после работы, всё же закончил этот текст. Понимая, конечно, что в пятничный вечер его вряд ли кто-то прочитает. Но правило есть правило. Приятных вам выходных.

Since our previous timeline update, we have encountered additional unexpected delays in our production progress. These delays are the result of a necessary hardware revision to account for MacOS users. During late stage testing, our team encountered issues with USB signaling on Mac devices, and while able to find potential workarounds, agreed that the next step would be to modify the PCB design to address this issue. HackRF Pro will ship as r1.2.1, our final revision. We decided that this revision was imperative to ensure that all users could have an equal user experience with HackRF Pro, regardless of operating...
АМС-100Ф. «Народный» кассовый аппарат двухтысячных
Приветствую всех!
Когда-то давно я уже рассказывал про устройство и работу кассовых аппаратов с фискальной памятью.
Так уж вышло, что один из имевшихся у меня экземпляров я тогда так и не показал, хотя на самом деле его воистину можно назвать одним из символов касс той эпохи. Что же в нём такого примечательного? Сейчас и узнаем.

Solving the NYTimes Pips puzzle with a constraint solver
The New York Times recently introduced a new daily puzzle called Pips. You place a set of dominoes on a grid, satisfying various conditions. For instance, in the puzzle below, the pips (dots) in the purple squares must sum to 8, there must be fewer than 5 pips in the red square, and the pips in the three green squares must be equal. (It doesn't take much thought to solve this "easy" puzzle, but the "medium" and "hard" puzzles are more challenging.)
