This is a followup to my recent post on concrete fasteners. A large-scale furniture assembly project has been polished off and it’s about time to give anchoring our bookshelves to the walls a go.

Side-by-side comparison of the stainless steel concrete fasteners I’ve got right now. L-to-R: Tapcon 410 SS washer-head 1/4-inch screw, 304 SS M8 wedge anchor, and two 304 SS sleeve anchors (M6 and M8). The high floor-to-near-ceiling metal book shelves have been assembled, but all of our books (except for ones we’ve needed since the relocation) […]
Earlier this month, I wanted to replace the bolt-feet on the bottoms of some filing cabinets with wheels, so I flipped one of them on its side, unscrewed one of the foot-bolts, and tried it in the closest-looking (size-wise) pieces of my bolt size-and-thread-check set, and found that it went smoothly into the female end […]
Recently, I mounted a few pairs of metal chests of drawers piggyback-style, which entailed drilling some holes. To keep the point of my drill from skittering away, I used a center punch to create a tiny dimple at each of the intended hole locations. Intending to clean the drill and the deburring tool that I’d used on the holes (a hex-shank deburring blade in a hex-shank handle as you can see in the photos below) once I had unpacked the tool-cleaning stuff (WD-40, Fluid Film, etc.), I laid them both — along with the center punch — on a fragment of one of the polystyrene foam sheets in which the metal drawers had been packed for shipment.
New-in-tube ATTEN T130-2.0SK soldering iron tip. This is a mostly-photos followup to , which concluded with some photos taken of a lightly used T130-2.0SK ATTEN soldering iron tip, described online as a knife tip. It gets inserted into a corded handle that, in turn, plugs into an ATTEN GT-series soldering station (such as the ATTEN […]

Phone-camera-microscope’s-eye view of the surface of the wrist wrest pad glued onto a computer keyboard. A 2023 Kickstarter project for a high-magnification mobile-phone-camera microscope that closed to new backers last December (iMicro Q3 – A Fingertip Microscope toward the Optical […]
Post-soldering, post-cleaning pic of the protoboard and rows of pin headers used in this little test, labeled with the solder wire used for two pairs of 2×4 pin header blocks: 8 pins soldered with no added flux and then 8 pins soldered with Chip Quick CQ4LF liquid flux, done for each alloy. I’m saddled with […]
Post-soldering, pre-cleaning photo of the protoboard and rows of pin headers used in this little test. Numerous punishing soldering sessions have left this solderless breadboard stained, scorched, and cracked and it is not long for this world. Recently, I posted about picking up soldering again after a hiatus () and I’ve gotten some fresh spools […]
Yesterday, I encountered an odd issue where ScreenToGif seemed unable to use its own bundled or downloaded-at-install-time version of gifski (
gifski.dll).
One of a few snapshots I took of the same soldered pins, in between twiddling the focus height adjustment on a microscope. In this first of three images, the uppermost bits of the pins are the most in-focus features. This and the next two photos are taken of a small region on the prototype board […]
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 […]
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 […]
