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 […]

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, […]

Stubby bits for low-profile offset ratcheting screwdrivers

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 […]

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 […]

Contrivances HerpDerp Mucking About With Things Sodding soldering The Diary of Lupin Pooter
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 […]

Calibration slides: a boon for measuring small things like the dimensions of solder pads on surface mount components

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 […]

Success: eliminated as non-optimal one way of soldering wires onto tiny, irregularly-shaped components

HerpDerp Mucking About With Things Sodding soldering Testing TØØLS
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: […]

The wheeled cart I purchased to make moving my Quick 6601 solder fume extractor and purifier around. Inside the box, newspaper recycled as environmentally-friendly packing material. The wheels were an optional add-on, replacing the default rickety all-plastic casters.

The “before” view of my second experimental setup. Three types of PTFE tape, two PTFE-impregnated glass fiber tapes and one straight PTFE tape, all with silicone adhesive, under test. How do you hold components in place while soldering? Not the PCBs on which the components are mounted. PCB holders and PCB vises can be pricey […]
