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 […]

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 […]

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.

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 […]

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 […]

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 […]

Caution: Avoid swallowed by children. Rinse immediately with water if contact with eyes. We’ve been checking out the labels on the cleaning products, soaps, shampoos, deodorants, etc. that we use, looking for quats or substances that release them. Here’s an article that’ll give you an idea of why: Questioning quats’ safety, published in Chemical & […]

HerpDerp Teardowns The Diary of Lupin Pooter
To satisfy my own curiosity, I recently tore down two old Canon multifunction printers, an inkjet and a laser. When I removed one of the motors, the relative positions of the hole into which the gear on the motor axle had gone and two rivets (which were actually the ends of metal axles for other […]

I bought the tickets months ago and promptly forgot about it until I flipped to this week’s page in my tried-and-true dead-tree calendar/planner. Thus it transpired that S. and I went to see ALVVAYS play at This Town Needs (the reincarnation of Hidden Agenda) out in Yau Tong (a gritty-by-HongKong-standards industrial area sort of but […]
