The screen of the (reassembled) SMART SENSOR AS808, displaying the ambient temperature and humidity as well as the date. We have some small and accurate-enough temperature and humidity sensors (“SMART SENSOR AS808”). They run on single AAA batteries and the batteries last for months and months. Their biggest flaw is the lack of any way […]

The pull-string cat toy, disemboweled. Some recently-bought cat toys came with spring-powered vibration motors. The springs (likely spiral torsion springs, i.e. watch springs) are loaded by drawing back a length of string attached to the motor’s axle. When you draw back the pullstring and release it, the eccentric mass on the motor’s axle causes the […]

Side-by-side comparison of the H4 bit that came with the low-profile, offset, ratcheting screwdriver (below) and the one from the JTC-7801 set (above). I bid you welcome to an exciting follow-up to a late-January post: Stubby bits for low-profile offset ratcheting screwdrivers. A few months back, I got a couple of low-profile, offset, ratcheting screwdrivers […]

To the best of our knowledge, neither S. nor I have yet had COVID aka the coof. We have, however, had our scares. In late December, I caught a cold. While I felt ill, I stayed home, had lots of hot chicken soup, and did rapid antigen tests for Covid as well as RATs for influenza and RSV each day.

Wera 05004525001 Belt A Deep 1 Socket Spanner Set (1/4 Inch). Plus a 4mm deep socket purchased separately. Deep sockets are one of those tools that, every so often, I could’ve really used but managed to get along without. So I got a , Wera’s 05004525001 deep socket set (1/4-inch drive). It’s got 9 pieces, […]

This is the bent-up-end offset ratcheting screwdriver. The Japanese company‘s name, Rubicon, is translated into Chinese as Robinhood. With a specific task in mind, I recently got a couple of low-profile, offset, ratcheting screwdrivers. The kind that accept hex-shank bits. Specifically, two Japanese Rubicon brand jobbies: RGH-9A (straight and flat) and RGH-9B (bent-up at the […]

This woman exposed seemingly every part of herself to the machine’s three spritzers. See the jets of mist? We were passing through a shopping mall in Tsuen Wan recently and noticed a man standing in front of a rectangular machine and bathing himself in jets of white mist, as the woman is doing in the […]

Huh. Didn’t read this label on the bottom of the mug until I’d turned it upside-down to hand-wash the base. This Fallout-themed mug had been sitting in our kitchen sink for a day or so, exposed to water to the extent that, when the tap was used, some water splashed into the basin where the […]

Spotted this lost-pet poster for a parrot near a bus shelter early last month and, just now, stumbled across the photo I snapped of it at the time. Hope they found the bird!

A pair of NOS gloves that I donned to protect my hands while snipping off lengths of 304 stainless steel mesh. Handling a couple of small rolls of clean-looking SS for a few minutes left them visibly filthy. Buying stuff from merchants in China directly, rather than from a retailer whose stock comes from a […]

Here’s a zoomed-in image of my attempt to connect to an SCD41 sensor without soldering wires onto it or cobbling together some sort of jig with pogo pins. I recently got some SCD41 sensors. They report CO2 level in PPM as well as temperature and humidity. They’re also surface-mount, of the LGA variety and small […]
