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 […]
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 […]
The two sponges, side by side: cheap third-party sponge on the left and official Hakko-supplied sponge on the right. I’m still using the same cellulose tip-cleaning sponge included as an accessory with my Hakko FX-888D but I’ve been soldering more frequently in recent months and anticipate doing even more in the near future. When is […]
A new (minor) personal first: connecting and driving a display, from Arduino. Thanks to Adafruit for the tutorial (Monochrome OLED Breakouts) and open-source libraries I’m using to drive this little 128×64 OLED display. Note: I am a repeat Adafruit customer but purchased these particular displays from a Taobao merchant for a fraction of the Adafruit […]
Late last month, after needing to re-do a substandard bit of my own soldering work and finding it quite a challenge to get the solder to melt and flow, I did a of reading and concluded that I ought to try another solder alloy from a different manufacturer and that de-soldering might be a heck […]
Last week, I wanted to test-drive one of the 24-LED WS2812 5050 RGB LED rings I’d bought a ways back. Getting it working, controlled by an Arduino board running the Adafruit NeoPixel library, was easy peasy. Except for the soldering step. For reasons that weren’t apparent to me while I was wielding my soldering iron, […]
