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 […]
One of the calibration slides, with the 1-mm-per-division scale above a new surface-mount CO2 sensor from Sensirion. I hadn’t aligned the start of the scale with the left side of the sensor yet, but it’s 1 centimeter (10mm) square. The trend seems to be that the share of interesting new thingamajigs and doodads available only […]
Pre-solder-enblobbening photo of my jury-rigged fix for an obliterated solder pad intended for the positive pin of a coin-cell battery holder mounted on the reverse of the PCB. In recent months, I’ve been lending a helping hand to a few people who’ve shown interest in electronics. I’m not an EE or an electronics expert of […]
Behold, my home workbench. The component I hoped to solder is bathed in the illumination from my microscope’s LED ring light. Tonight, I tried one very simple way of holding an itty bitty, non-flat electronics component and some wires still while I solder the stripped ends of the wires to the pads on the component: […]
