Won’t fly far, fethers [sic] snipped

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!

Dusty, grimy, sometimes packed in trash, and occasionally short

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 […]

Soldering fixture test: stainless steel mesh + silicone foam

Contrivances Mucking About With Things The Diary of Lupin Pooter
Here’s the setup I tried: a cut-off length of white silicone foam (with a 15mm x 20mm rectangular cross-section), a roughly square piece of stainless steel mesh, and binder clips securing the mesh against the foam. On occasion, one needs or wants to solder wires to a small and irregularly-shaped component. Last month, I tried […]

This may not have worked (reliably) even if I’d had the pin ordering correct

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 […]

Hits and a miss, sort-of fixing obliterated solder pads on a PCB

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 […]

Is that the way it is? The Diary of Lupin Pooter
Before heading to a “community testing center” for government-blessed RT-PCR tests, we each did a home-based pinprick blood antibody test. I’ll restrain myself, insofar as possible, from commenting here on Hong Kong politics beyond observing that the territory continues to pursue, as best one can tell, a “zero-COVID” policy. Please know that the title of […]

Wheels for the wheel-less QUICK 6601

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.

Storage shelf mitosis

Measuring the shelf upright, trying to figure out the best location for my hacksaw cut. Storage, storage, storage. Utterly tedious, once you’ve made your plan and purchased the storage hardware, and yet at the same time so necessary. Recently, I erected some shelving in our storage room (which was actually intended as the bedroom for […]

Mushy bars of soap: testing a countermeasure

The plastic countertop soap dishes we’ve gotten have ridges intended to keep the soap bar a millimeter or so above the rest of the dish surface. Those ridges are a bit on the wide, long, and numerous side, however, and the result is that the parts of the bar that contact the ridges stay moist longer than the rest of the bar and those areas often feel mushy the next time one grabs the soap.

Top of my Quick 6601 solder fume extractor and purifier, with the tethered remote control and not-yet consulted Chinese-language instruction manual resting next to the base of the flexible duct. There wasn’t much assembly involved. One end of the flexible duct slides onto the flange mounted atop the machine and attaching the flared rubber intake […]

New microscope for the workbench

Snapshot of the screen showing part of the calibration card included with the microscope’s camera. The magnification goes much higher but this is the highest at which a meaningful bit of the card is visible. I recently acquired a new workbench microscope (a SHOCREX 3800W) from the manufacturer’s (or rebadger and reseller’s) Tmall store. I […]
