Mucking About With Things Teardowns The Diary of Lupin Pooter To see a world in a grain of sand
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 story begins a few weeks back. While tightening up some loose kitchen cabinet and drawer handles and the screws that attach drawer sides to drawer slides, I replaced several of the handles’ countersunk Phillips-head screws with hex-head bolts and washers. Phillips-head screws that were easy to reach straight-on with a screwdriver were snugged-up and […]

I picked up a 2nd assortment of cheap-o carbon-steel Forstner drill bits a while ago. The bits in the new set have thinner shanks, so they’ll fit in my beater cordless drill’s smallish keyless chuck, which is just barely too small for the girthier Irwin-brand Forstner bits. Their shanks are also hexagonal and less slippy […]

Until yesterday evening, I’d never consumed any fresh grapefruit. I had an inkling that it was less sweet than, say, an orange and recall reading or seeing or hearing that some people salted cut grapefruit to mask the bitterness (for a pop-sci explanation, check this October 2020 news article at science.org: Why adding salt makes […]

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 […]

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 […]
