Last time, I mentioned that our older ceramic knives’ plastic handles had developed cracks and propounded my hypothesis that the cracking was a consequence of the blade material and the handle material having different coefficients of linear thermal expansion and my having, in the past, run them through our dishwasher periodically.

Today’s post: two short clips of the changing condensation patterns on the inner surface of the glass lid of a stockpot, filmed consecutively while I was hard-boiling a couple of dozen eggs at some point in the past few days. The videos are set to loop and are muted by default but the audio is […]
Not very long ago, I mounted some metal fixtures, made of 304 stainless steel. The fixtures were intended to be affixed to their substrate using adhesive and each one came with a tube of glue. How robust an attachment the stuff would create, I cannot venture to guess, and I opted to use screws. An […]
S. and I recently visited a local landmark-slash-mini-park: Blackhead Point, the site of Signal Hill Tower, a brick structure erected in 1907, subsequently enlarged, and shortly thereafter abandoned. Photo of Signal Hill Tower (in Tsim Sha Tsui, Kowloon, Hong Kong), taken by yours truly in December 2023. Each day at 1pm, a large copper sphere […]
Cross-threading is a bummer. Through a momentary lapse in punctiliousness, I apparently managed to get a male-threaded pipe plug started into the female-threaded end of a piece of pipe at a tiny angle. Or, given that the plug didn’t seem to be canted at all, perhaps I failed to remove a particularly pernicious bit of […]
Below is a photo of some corroded rebar, exposed through spalling, on the floor of a multi-level underground car park in a residential complex here in Hong Kong. Snapshot of a section of floor in a multi-level underground parking lot. Today’s other photo is of a rusty cover for some sort of plumbing/electrical infrastructure access […]
I was looking for some large-ish SMD LEDs to incorporate in a paper circuit, using copper tape for the traces, on a note card, to try out 3M 9703 tape (3M Electrically Conductive Adhesive Transfer Tape 9703), sometimes referred to as z-axis conductive tape because it doesn’t conduct laterally (from side to side, i.e. along […]
Animated GIF clip of me soldering one pin on a breakout board. This afternoon, I soldered some breakout boards and recorded the process using the camera on my recently-acquired microscope (a SHOCREX 3800W) and used my other recent purchase (a QUICK 6601 solder fume extractor and purifier) to deal with the flux smoke instead of […]
Snapshot of the screen showing part of the calibration card included with the microscope’s camera. The magnification goes much higher but this is the highest at which a meaningful bit of the card is visible. I recently acquired a new workbench microscope (a SHOCREX 3800W) from the manufacturer’s (or rebadger and reseller’s) Tmall store. I […]
See anything interesting in this photo? Neither of us did at first, either, when we were having a gander at the original scene a few months back, but I paused our walk for a moment, to her minor exasperation, to give the spot a quick once-over. Here’s a closeup. That vase-like object is a potter […]
INVENSENSE MPU-6050 [D4H592LAT EL 1539 E]: snapshot taken with a Canon G7X through a handheld 40x magnifying glass because they were good enough for my purposes and the scopes are all packed away at the moment.
That’s a photo of the stainless steel panel on the inside of the lid of our water boiler/warmer.
