Temporal Anomaly Clock.
The clock shows time with its local anomalies.
The sensitivity is set to 5 but "it goes up to 11".
I did not dare go set it that high.

Here are two animations revealing time: SlotMachine and Matrix. Both of them require some fine tuning but I am not sure which one to pick.

I ordered 20 of those connectors and received 280. I am trying to imagine how this might have happened.
1. Disgruntled employee packed the content of the entire bin.
2. One picker instead of taking one pack from a bin took entire bag and went for a lunch. Another one put the whole bag into a box..

Yes, I got them from a thrift store for pennies. Thanks to your question, I found one that is more affordable 😃

After my manual initial test, Gemini "suggested" code with Adafriut LEDBackpack library, but the code did not work as the library 7segment class assumes only 4 digit display with a colon in the middle. It ended up generating more generic logick.

I am in love with 1970s calculator bubble LED displays. Cuteness overload!
I am using HT16K33A breakout board because it is a damn common anode display.
I will add an RTC this time, but this will require a level shifter.

Based on images of other devices, unlikely. Could have been pretty 😍

Posting the most beautiful rat picture from 1990s. I do not have an electronic copy of the original - just its imperfect printout scan

"The designers managed to get the IC count down to just 29." No wonder that it does not have leading zero suppression.

Yesterday's thrift store find: Royal Digital I calculator with VFD display. The curious thing is the use of lowercase 'o' to display blanks and zeros. Technically, the blanks are zeros, but they are being suppressed in contemporary displays.
