The Diary of Lupin Pooter
The maxim No act of kindness, no matter how small, is ever wasted. is attributed to Aesop and the fable of The Lion and the Mouse. Today, I’m pleased to bear witness to a good deed done by an unknown stranger. The act of kindness in question strikes me as quite likely completely altruistic as […]

Spitting Images The Diary of Lupin Pooter
I cribbed this entry’s title from the English text of a peculiar sticker that I saw on the rear hatch window of a minivan and used a cropped version of the least-blurry image I took through our taxi’s front windshield for the post thumbnail.

Fluoride testing tap water, retail-purchased bottled spring water, and distilled water

Looks like 0.5 mg/L (equivalent to 0.5ppm) of fluoride in our tap water. According to the Use fluoride page at toothclub.gov.hk, the fluoride concentration of our tap water should be 0.5 mg/L (equivalent to 0.5ppm): Domestic water in Hong Kong has been fluoridated since 1961. This has led to a great decline in the incidence […]

Some of S.’s colleagues recently gifted her a couple of attractive, packaged-for-gift-giving-purposes cakes they’d purchased while on holiday overseas. One of the cakes, cherry-blossom-themed, with the transparent plastic removed. One of the cakes featured a cherry blossom motif. It was made of yellow sponge cake to which red or pink food coloring had been added, […]

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 […]

A very basic, DIY-ish night-vision camera equipped with 2 beefy IR LEDs recently landed on our doorstep and S. and I took a nighttime stroll to try it out. The short video below was taken with a phone camera aimed at the night-vision camera’s screen while the LEDs were switched on. In low light, the […]

I recently restocked my assortment of medium-to-large ziploc bags after finally using up the last of the previous batch, which were extra-heavy-thick but tended to crack (ah-yup, literally crack and split) over time when folded or bent slightly. This time, I went with a different Mainland manufacturer and just extra-thick rather than extra-hevy-super-duper-thick. They’re thinner […]

Labels for stored nuts and bolts as a simplest-possible, just-barely-useful task to furnish motivation needed to begin learning CAD software (FreeCAD)

Three containers of M2 coupling nuts (304 stainless steel) bearing my taped-on homemade labels, along with the retailer’s packaging (clear plastic heat-sealed baggies). Motivation is critically important in task-based learning, but acquiring a new skill from scratch can be a hard slog even when you genuinely, even urgently, need to be able to do the […]

Got new cans of Fluid Film after a long drought. On the left is one of my new cans. My last, empty can is on the right. Fluid Film is great, but it was difficult to obtain (for yours truly) for a long while. I’d gotten my last cans of the stuff courtesy of someone […]

Fixed the zipper on a woven-polypropylene (PP) bag aka 蛇皮袋 (Snakeskin Bag in Simplified Chinese). Recently, I stuffed a woven-polypropylene bag a mite too full of stuff and managed to pop the its zipper slider (the thing with two nostril-like orifices which one pulls back and forth) off one side of the zipper’s “chain” (the […]

A human hand as viewed by a FLIR ONE Pro infrared camera dongle for Android phones. Temperature measurements with K-type thermocouple probes (to which I alluded in a previous entry: Hardwired auto-off sucks. Don’t build it into tools/instruments you design.) are useful, but you’ll only get readings at the precise locations where you place the […]
