I was looking for some large-ish SMD LEDs to incorporate in a paper circuit, using copper tape for the traces, on a note card, to try out 3M 9703 tape (3M Electrically Conductive Adhesive Transfer Tape 9703), sometimes referred to as z-axis conductive tape because it doesn’t conduct laterally (from side to side, i.e. along […]

A very basic, DIY-ish night-vision camera equipped with 2 beefy IR LEDs recently landed on our doorstep and S. and I took a nighttime stroll to try it out. The short video below was taken with a phone camera aimed at the night-vision camera’s screen while the LEDs were switched on. In low light, the […]

I recently restocked my assortment of medium-to-large ziploc bags after finally using up the last of the previous batch, which were extra-heavy-thick but tended to crack (ah-yup, literally crack and split) over time when folded or bent slightly. This time, I went with a different Mainland manufacturer and just extra-thick rather than extra-hevy-super-duper-thick. They’re thinner […]

Labels for stored nuts and bolts as a simplest-possible, just-barely-useful task to furnish motivation needed to begin learning CAD software (FreeCAD)

Three containers of M2 coupling nuts (304 stainless steel) bearing my taped-on homemade labels, along with the retailer’s packaging (clear plastic heat-sealed baggies). Motivation is critically important in task-based learning, but acquiring a new skill from scratch can be a hard slog even when you genuinely, even urgently, need to be able to do the […]

Got new cans of Fluid Film after a long drought. On the left is one of my new cans. My last, empty can is on the right. Fluid Film is great, but it was difficult to obtain (for yours truly) for a long while. I’d gotten my last cans of the stuff courtesy of someone […]

Fixed the zipper on a woven-polypropylene (PP) bag aka 蛇皮袋 (Snakeskin Bag in Simplified Chinese). Recently, I stuffed a woven-polypropylene bag a mite too full of stuff and managed to pop the its zipper slider (the thing with two nostril-like orifices which one pulls back and forth) off one side of the zipper’s “chain” (the […]

A human hand as viewed by a FLIR ONE Pro infrared camera dongle for Android phones. Temperature measurements with K-type thermocouple probes (to which I alluded in a previous entry: Hardwired auto-off sucks. Don’t build it into tools/instruments you design.) are useful, but you’ll only get readings at the precise locations where you place the […]

All My Friends Are Insects HerpDerp Is that the way it is? The Diary of Lupin Pooter
S. and I stopped in a local pet supplies store this afternoon and some peculiar flavors of canned cat fodder caught my eye. Sandwiched in between some of the traditional fish-and-fowl-based products were rows of unusual combos, proudly labeled as having been made in Taiwan: CRICKET & CHICKEN, RAT MEAT & CHICKEN, MEALWORM & CHICKEN, […]

Decadal review of the Belkin Verve Tab Folio for Kindle Paperwhite and Kindle Touch, Black

Nearly a decade ago, S. and I bought Belkin ‘Verve Tab Folio’ cases for our then-new Kindle Paperwhites (1st-gen EY21 Wifi-only units). Neither of our Kindles, which we got out of an abundance of optimism, has been used terribly often. Mine was almost always kept in airplane mode and employed as a portable PDF reader, […]

Snickers in purple wrappers emblazoned with odd phrases on a 7-11 shelf. I found myself in a 7-11 a few days ago, needing to make a purchase, any purchase, and scanned the shelves for something small to buy. I’m not bigly into candy and rarely buy any, but the purple-wrapper-ed Snickers bars printed with odd […]

I like my Wera 42-piece 8100 SA 2 Zyklop Speed Ratchet Set [1/4″ drive, metric] and it sees a fair bit of professional-amateur tinkerer usage, particularly the included 8784 A1 Zyklop bit adaptor, 1/4″ (05003529001), with hex-inner or Torx drive bits. Often, though, I’ve had to dig out a separate bit assortment to get a […]

Having a gander inside a SMART SENSOR AS808 (an inexpensive, standalone 1xAAA-powered temperature and humidity sensor)

The screen of the (reassembled) SMART SENSOR AS808, displaying the ambient temperature and humidity as well as the date. We have some small and accurate-enough temperature and humidity sensors (“SMART SENSOR AS808”). They run on single AAA batteries and the batteries last for months and months. Their biggest flaw is the lack of any way […]
