HerpDerp Mucking About With Things Teardowns The Diary of Lupin Pooter
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 […]

One of life’s little vicissitudes: shrinky-dink sneaker insoles. We send laundry out and get it back washed, dried, and bagged. I’ve washed sneaker insoles many, many times. In a first for our household, a pair of insoles came back heat-shrunk to about two-thirds of its original size. The image above shows an identical pair of […]

Ugly, but it works: DIY Lightbulb-grabber because we couldn’t find one locally or get one shipped from the Mainland

Once upon a time, this was a water bottle. The light bulb in our storeroom blew back in February. The ceiling in that room is high enough that replacing the bulb from a stool isn’t do-able and the layout of our place (little doorways, narrow hall, and tight corners) makes maneuvering the fiberglass stepladder ladder […]

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.

Purring is reportedly very complex and often misconstrued

Marceline grooming Bubblegum. Marceline grooming Bubblegum. Both cats seemed content, but neither was purring. I’ve only ever heard a cat purr when being brushed or stroked (aka petted) by a human being. Certainly that’s the only circumstance under which any cat I’ve owned or cared for has purred, but the BBC says that a cat […]

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 […]

Don’t you wanna watch me spill? Alerting when a container is nearly full of liquid.

There may come a time when you need to know if a container being filled with liquid that flows at a slow, variable rate is nearly full so that you can empty the contents or do something else with the stuff inside. Such a need recently arose here and I put something together using an Arduino (Cloneduino) Nano, a couple of non-contact capacitive water level sensors, a WS2812 LED breakout board, and a piezo buzzer.

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!
