This is a followup to my recent post on concrete fasteners. A large-scale furniture assembly project has been polished off and it’s about time to give anchoring our bookshelves to the walls a go.

Have you ever listened to a long interview or podcast or a nice, long vlog and then, just a couple of days later, when you got the itch to look up something like a book or a song you heard them mention found that you just couldn’t quite remember the title or the name of […]
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 […]
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 […]
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 […]
Concluding frames of the commercial for MEGO’s ‘Forbidden Zone Trap’ Planet of the Apes playset. Vault of Vintage Toys recently posted an image of the box for a 1970s-era MEGO Planet of the Apes (check out All PLANET OF THE APES Original Franchise Trailers (1968 – 1973) if you’re only familiar with the remakes) playset: […]
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 […]
A new bit of hardware needs to be bolted down to the benchtop during use but I’d like to be able to stow it away the rest of the time. The base of the item in question features four M8-diameter holes, so I hunted around for stainless steel threaded inserts. I could only find stainless […]
Two lemon batteries, connected in series, can (just barely) power a red LED. Making a lemon battery was one of the sciencey activities I encountered frequently while leafing through children’s science-experiments-you-can-do-at-home and “rainy day” activity books when I was a young’un and wanted to try but couldn’t. As this article explains, a single lemon isn’t […]
Count the ZOTAC GPU boxes. Don’t forget to smile and wave at the surveillance camera pointed at the open door. It and the street-facing windows are open to facilitate a cross-breeze for free, or at least cheap, cooling. I’m looking for workshop space. It’s Hong Kong and we’re dealing with Hong Kong real estate agents […]
Can you tell the difference between the joins made with a type of SAC305 solder (top) and the K100LD solder (bottom), both from Kester? It occurred to me recently that I had no idea how much solder remained on the spool I’d been using, of the SAC305 alloy (Indium Corporation’s CW-807, a SAC305 (96.6% Sn, […]
How long did it take you to spot the rainbow? The rainbow faded from one second to the next and, even at the moment I took the above photo, S. had to point it out to me. The fainter second rainbow, above and to the left of the first, only became apparent when I opened […]
