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 […]

Calibration slides: a boon for measuring small things like the dimensions of solder pads on surface mount components

One of the calibration slides, with the 1-mm-per-division scale above a new surface-mount CO2 sensor from Sensirion. I hadn’t aligned the start of the scale with the left side of the sensor yet, but it’s 1 centimeter (10mm) square. The trend seems to be that the share of interesting new thingamajigs and doodads available only […]

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 […]

Success: eliminated as non-optimal one way of soldering wires onto tiny, irregularly-shaped components

Behold, my home workbench. The component I hoped to solder is bathed in the illumination from my microscope’s LED ring light. Tonight, I tried one very simple way of holding an itty bitty, non-flat electronics component and some wires still while I solder the stripped ends of the wires to the pads on the component: […]

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.

The “before” view of my second experimental setup. Three types of PTFE tape, two PTFE-impregnated glass fiber tapes and one straight PTFE tape, all with silicone adhesive, under test. How do you hold components in place while soldering? Not the PCBs on which the components are mounted. PCB holders and PCB vises can be pricey […]

Animated GIF clip of me soldering one pin on a breakout board. This afternoon, I soldered some breakout boards and recorded the process using the camera on my recently-acquired microscope (a SHOCREX 3800W) and used my other recent purchase (a QUICK 6601 solder fume extractor and purifier) to deal with the flux smoke instead of […]

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 […]

Knocked together several different cheap Chinese PCB-plus-through-hole-parts electronics kits as a means of trying out a couple of different soldering iron tips, whilst listening to some recent podcast interviews with Harvard astrophysicist Avi Loeb. The surface of the yellow silicone mat on which I worked is speckled with tiny dried droplets of rosin and will […]

The seller included the pin headers but yours truly had to stump up the 2P screw terminals. Today’s recreational soldering: some breakouts for Si4599 MOSFETs and a couple more for LTC2944 battery-monitoring ICs. The photo was taken through the lens of a flex-arm-mounted magnifier removed from a set of “helping hands” and remounted in a […]

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, […]
