From left: call button receptacle, call button plugged in (button itself dangling) with red reset button overhead, and a red triangular emergency-pull knob with its own reset button above it. I’ve spent a couple of days in and out of Hong Kong’s Prince of Wales Hospital, not ill myself, but advocating for and looking after […]

When Goop goes bad

It had been a year or more since I’d needed the cleaning power of Goop, but need it I recently did, so I dug out my mostly-full 14-ounce container of orange-scented Goop-with-pumice. To my surprise, I found that the lid had cracked and its top had separated from its rim. Of course, it would’ve been […]

You Need Cry, Dear sort of, very loosely, sounds like the characters printed in Chinese beneath the nonsensical English. The Chinese translates to something close to “Have your express delivery.” Once you start down this path, making the mascot a bowtie-sporting cartoon deer is the obvious next step.

HerpDerp The Diary of Lupin Pooter We'll go much more a roving
It was a public holiday and so we spent the afternoon back in the cut, crawling through promising-looking industrial buildings in a corner of the New Territories. As connoisseurs of light-industrial decay, we savored the innumerable signs of shoddy construction enhanced by decades of deferred or improperly executed maintenance and the exquisite stratigraphic layering of […]

Rad sign, eh? Workspace Search 2018 seemed to be inching towards a satisfactory dénouement, but it was just one of those pesky false endings. The adventure continues. “It’s freezing up here. What did you use to keep warm?” “Indignation,” said Michelangelo. “Best fuel I know. Never burns out.” Irving Stone, The Agony and the Ecstasy […]

Why go to all of the fuss of repairing “undulating” pavement if you can simply tape up warning notices about the issue and call it a day? In one industrial neighborhood we visited today, identical copies of the helpful sign shown above were taped to the I-beams sunken into the cement ridges bifurcating the sidewalk.

Looks like a worthwhile use of GPUs to me!

Count the ZOTAC GPU boxes. Don’t forget to smile and wave at the surveillance camera pointed at the open door. It and the street-facing windows are open to facilitate a cross-breeze for free, or at least cheap, cooling. I’m looking for workshop space. It’s Hong Kong and we’re dealing with Hong Kong real estate agents […]

HerpDerp Mucking About With Things Sodding soldering The Diary of Lupin Pooter
Two specimens of the same model of timer. Top: an as-yet-unused timer, opened up to show its innards. Bottom: my good-enough-for-now five-minute fix: soldering an SMD pieze buzzer to two of the leads on a transistor inductor. A few days ago, a dual-clock kitchen timer we’ve had for years stopped making much noise when its […]

Lead-free solder recommendation: Kester K100LD for shiny lead-free solder joins

Can you tell the difference between the joins made with a type of SAC305 solder (top) and the K100LD solder (bottom), both from Kester? It occurred to me recently that I had no idea how much solder remained on the spool I’d been using, of the SAC305 alloy (Indium Corporation’s CW-807, a SAC305 (96.6% Sn, […]

My soldering is still, gradually, improving. All four of the LoRa transceivers above have had 2.0mm-pitch pin headers attached. Two of the transceivers above are slotted into female headers on pre-made adapter plates which I purchased from an online vendor. THe other two have been soldered permanently onto bare adapter plates to which I fitted […]

Can you spot the little faces in this discarded, mangled length of Dupont connector reel-end? Tonight, I’m helping my better half with a work-related project. Nearly a hundred and fifty 4-AA battery holders and the same number of mini speakers need to have breadboard-friendly connectors affixed to the ends of their leads and I have […]
