Crimping JST-XH Sensor Harness Terminals Without a Factory Tool: A Measured Procedure
November 10, 2026Why a marginal crimp looks like a firmware bug An ESPHome node that reports a temperature every 30 seconds and then goes unknown for two minutes is not usually a firmware problem. If the dropout correlates with someone opening the enclosure, moving a cable bundle, or a cold night, the first suspect is the harness.

The failure mode: you can’t tell what broke because you never wrote down what the device was A Zigbee contact sensor stops reporting. The dashboard shows it unavailable. You have three plausible causes and no way to separate them: the…
The ‘Not Friendly Do Not Touch’ Shirt: A Warning Sign That Works Because It’s Not a Slogan
The first thing I notice is the triangle. A yellow caution triangle, the kind you see on a ladder or a chemical cabinet, sits above the words NOT FRIENDLY and DO NOT TOUCH. Below the lettering, a hand is crossed…
The Large ‘meh.’ Shirt: Why Visual Loudness Is the Whole Joke
The native garment preview shows large bold white lowercase meh. lettering on a dark shirt. No animal illustration is present. That is the entire design, and the entire design is the argument: a word that means I have no strong…
How to Test a Smart Plug’s Local Fallback Without Cutting the Whole Network

The ‘I Wear This Shirt Periodically’ Shirt: Four Element Tiles and the Difference Between a Pun and a Promise
The shirt reads I WEAR THIS SHIRT PERIODICALLY, and beneath the sentence sit four periodic-table-style tiles: 53 I, 74 W, 22 Ti, 16 S. The tile symbols are I, W, Ti, S — not a literal spelling of the sentence.…
