"show cat" yea, sure, I haven't posted this thing in a while. I still love it to bits and will be very sad if it develops serious problems.
Though I also wish its creator a long, healthy, and safe life free of Russian aggression, and not just so they can help me replace it/parts!

@Sariat @ami_angelwings
Yeah, as an #Accordion historian I enjoy pointing out that pirates never played Accordions cause they weren’t invented until the age of railroads in the 1800sCharles Wheatstone who invented the little concertina actually sold the first popular telegraph
It took the same industrial technology to produce the parts that go into accordions as steam engines
#Clock makers experimented laboriously and inaccurately with gears earlier ⚙️
Add magic? 🤷🏽

The Clock and The Calendar Didn’t Have to Look Like This
Two of our basic time units are non-negotiable. A day is one rotation of the Earth. A year is one trip around the Sun. Nature hands us these whether we like it or not, no civilisation ever had to invent the day. Everything else - the week, the month, and even the hour, minute, and second - is a human invention layered on top. Nothing in physics requires 24 hours, 60 minutes, or a 7-day cycle. We made all of it up. And the fact that nearly every civilisation independently arrived at something […] -

@arstechnica RE: my SNTP Clock project.
I had a similar itch and turned it into a project to teach myself FreeRTOS, ESP-IDF (on ESP32 DevKitC), KiCAD, PCB layout and ordering, parts sourcing, hand surface mount soldering, FreeCAD, 3D printing, MQTT, and rewrote parts of SNTP and wrote a robust linear regression algorithm for tracking rate and phase error. I developed it during the CoVID-19 pandemic. I had worked with similar things in my embedded software career but never done all these things myself. And used no AI. There is no wrong way to do this. My result looks similar and uses many of the same parts (initially via Adafruit, then direct from Digikey and Mouser). It's a journey of self-reward. #sntp #clock #project #smd #embedded #hobby -

I have a cursed object in my office. A cursed #horological object, to be specific.
I have an LED display clock (red, naturally) with a fairly large display, about 55mm high. It was cheap, partially because it has no internal power supply - it runs off USB power.
Oddly, it's one of the most accurate clocks in my house. I have never seen it gain or lose a minute versus my NTP-synced or ELF-synced clocks.
It has enough juice in its reservoir/filter capacitor that it rides out a lot of power outages without losing the time or settings. It's only with extended outages, say 10 minutes or more, that it comes up without the correct time on it. As such, I rarely have cause to dive into its settings.
The last power outage we had that cleared this clock, I left it set to 24-hour time, where I usually switch it to 12-hour. And then I found out it is cursed.
It skips the leading "0" on times where the hour is a single-digit. So it displays, for example, "3:14" rather than "03:14". And the bit that makes my head spin, it displays a single "0" for 12-1am...
"0:23" is seven flavours of wrong.

What Is a Strike Train? A Beginner’s Guide to Mechanical Clock Striking Mechanisms
If you have spent any time collecting or repairing antique clocks, you have probably come across the term strike train. For newcomers to the hobby, the expression may sound complicated, but the concept is actually quite simple.
In a mechanical clock, the strike section is the group of gears, levers, springs, and other components responsible for producing the clock’s striking function. The collection of those gears, levers, and springs is called the Strike Train.
In other words, it is the mechanism that allows a clock to strike the hours and, in some cases, the half-hours as well.
A mantel clock; the winding point for the time is on the right, while the winding point for the strike is on the leftNotice I did not use the word “chime”. Many confuse the words strike and chime. A strike is simply the strike of a rod (1,2,3 or even 4 rods) bell, or coil that produces a note(s). A chime is a musical tone, usually on the quarter hour, such as found on a Westminster “chiming” clock. Honestly, if we were both at a party talking about clocks and you called it a chime instead of a strike, I wouldn’t correct you unless you asked me whether that was the proper term.
Without a strike train, a clock would still be able to tell time, but it would remain silent. Clocks without a strike feature are called time-only clocks.
Most Mechanical Clocks Have Two Trains
Many spring-driven and weight-driven clocks contain two separate gear trains:
- The time train, which powers the hands and keeps time.
- The strike train, which powers the striking mechanism.
Some clocks, particularly those with more elaborate chime systems such as Westminster chimes, may have three trains: a time train, a strike train, and a chime train. Many of those clocks have three winding points on the dial face, one for each of the trains.
Occassioanlly you will find unusural clocks like a 2-train Westminsiter chime clock made by Sessions in the late 1920s.
When you wind a typical two-weight regulator or two-spring mantel clock, one weight or spring powers the time train, while the other powers the strike train. If you neglect to wind the strike side, don’t worry—the clock will continue to keep time. It simply won’t strike the hours until the strike-side weight is raised or the spring is wound again. The two trains operate independently of one another.
For a weight-driven clock, if only one side is wound, the other weight will not descend unless it is also wound. As a result, the clock will appear unbalanced to an observer.
A clock movement on a test standHow Does a Strike Train Work?
The strike train remains locked for most of the hour (or half hour). As the clock approaches a striking point, a series of cams, levers, and release mechanisms allows the train to begin moving, but just a little. This is called the warning phase, which usually lasts about 5 minutes.
Once released on the hour (or half hour), power from a mainspring or weight drives a sequence of gears that causes the hammer to strike a bell, gong, or chime rods.
All the levers on this rack and snail movement operate the strike trainThe clock then counts the appropriate number of strikes before the mechanism locks itself once again, waiting for the next striking cycle.
For example:
- One strike at 1:00
- Two strikes at 2:00
- Three strikes at 3:00
- And so on until twelve strikes at noon or midnight
This process occurs automatically and repeats day after day, often for decades or even centuries. as long as the clock is wound, of course.
What Parts Make Up a Strike Train?
Although designs vary from one manufacturer to another, most strike trains include:
- A power source (spring or weight)
- A series of gears and pinions
- A gathering pallet, (if rack and snail)
- A series of levers
- A warning mechanism
- A count wheel
- A hammer assembly
- A bell, gong, or strike rods
Each component has a specific job to perform. If any one of these parts becomes worn, bent, dirty, or improperly adjusted, the clock may fail to strike correctly or not at all.
A typical American time and countwheel strike movementCommon Strike Train Problems
Many antique clock owners eventually encounter issues related to the strike train.
Some common symptoms include:
- The clock strikes the wrong hour.
- The strike train stops midway through striking.
- The clock remains in warning and never completes the strike.
- The hammer fails to reach the gong.
- The strike train runs continuously without stopping.
In many cases, these problems are caused by accumulated dirt, dried oil, wear, or incorrect synchronization between the strike train and the motion work.
Fortunately, most issues can be diagnosed with careful observation and a basic understanding of how the mechanism operates.
Why Understanding the Strike Train Is Important
For clock collectors and hobbyists, understanding the strike train helps remove much of the mystery surrounding mechanical clocks.
When a clock strikes the wrong number of times or refuses to strike altogether, many people assume something is seriously broken. In reality, the problem is often a simple adjustment or a component that needs cleaning and lubrication.
Learning how the strike train works also provides a greater appreciation for the ingenuity of the clockmakers who designed these remarkable mechanisms centuries ago.
Final Thoughts
The strike train is one of the most fascinating parts of a mechanical clock. While the time train quietly keeps the hands moving, the strike train brings the clock to life by announcing the passing hours.
The next time you hear the rich sound of a gong or bell from an antique clock, take a moment to appreciate the intricate system of gears, levers, and springs working behind the dial. That sound is the result of a carefully engineered strike train performing the task it was designed to do many years ago.
