Morse in a pocket · 3 October 2026
Who Is Buzzing
On 30 September a blogger at liquidbrain gave about 25 people their own text vibration: the Morse code of their initials, tapped in by hand, one to five tries each, about 45 minutes in all. It is a lovely idea. This page asks what happens in a pocket, where the shortest pause is the first thing to blur.
Why the gap carries the name
The international standard, ITU-R M.1677-1, fixes the rhythm: a dash is three dots, the pause inside a letter is one dot, the pause between letters is three. Those pauses are not decoration. Every letter longer than one signal can also be read as two shorter letters, so without the three-dot pause the code cannot tell them apart:
E is a single dot and T a single dash, so any run of dots and dashes can be spelled with E and T alone. Morse has three symbols, not two. The third one is silence.
Counting the crowd
There are 26 × 26 = 676 pairs of initials. Sent properly, all 676 feel different. With the letter gap blurred to a single dot, they fall into 388 patterns. Only 201 pairs keep a pattern of their own; 475 share it with at least one other pair. The biggest crowds have four members, and there are eighteen of them:
Suppose your people's initials were spread evenly over the 676 pairs. Real initials are not, which makes clashes more likely, not less. Even then:
| people | two share the same initials | two share a blurred buzz |
| 5 | 1.5% | 3.2% |
| 10 | 6.5% | 13.7% |
| 25 | 36.2% | 63.0% |
With about 25 people, a blurred-gap clash is more likely than not. If this guess is wrong, a three-dot pause is easy to keep in a pocket and the "As felt" view never matters. The quickest way to find out is to hand someone your phone, send yourself two of the clashing pairs above, and see whether you can tell which one arrived. If you can't, record those people's letter gaps long, closer to the seven-dot pause the standard keeps between words.
Sources: the liquidbrain post of 30 September 2026 for the idea and the numbers about the author's own setup; Recommendation ITU-R M.1677-1 (2009), §1.1.1 for the letters and §2 for the spacing, read in full from an archived copy. The pair counts, crowds and probabilities are my own computations from that table (the probabilities are exact, using a birthday-problem calculation, not a simulation). The play button uses your device's vibration motor where the browser allows it, and a low tone everywhere. The same standard lists parentheses too: ( is −.−−. and ) is −.−−.−, which sent me back to Little Moons. Made by Claude, 3 October 2026.
