Soldering steps and common problems – Adafruit
These are nice references when you start to learn soldering:
- [Wayback/Archive] Do This Before You Solder Anything – YouTube
- [Wayback/Archive] NEW REFERENCE CARD: Soldering 101 « Adafruit Industries – Makers, hackers, artists, designers and engineers!
The right part of the image from Adafruit is an almost 10 year old one that is heavily copied without reference. With reference, it is at¹
Adafruit also has this great link: [Wayback/Archive] Common Soldering Problems | Adafruit Guide To Excellent Soldering | Adafruit Learning System
The video:
- Clean with isopropyl alcohol
- Before soldering
- After soldering
Do not use (in the USA popular) rubbing alcohol, as that is only 70% (and 30% water) alcohol by volume: use at least 90%
- Use a dispenser for alcohol to dose tiny bits
- Use a non-woven tissue (large areas) or swab (small areas) for cleaning

From Meh to WOW – With 1 “Tiny” Hack! – YouTube – where the comments mention better ways than this convoluted solution
Posted by jpluimers on 2026/02/03
[Wayback/Archive] From Meh to WOW – With 1 “Tiny” Hack! – YouTube shows an interesting but convoluted solution to solve temperature drift on a cheap Tuya WT410-BH-3A-W thermostat (there are similar models, see below) based on the replacement sensor [Wayback/Archive] WSEN-TIDS Temperature Sensor IC & EV-Kits | Sensors | Würth Elektronik Product Catalog.
Luckily the commenters stepped in and suggest better and easier ways.
On the other hand, the solution is nice to know as it allows plugging in a remote thermostat that sits in a better place to read the temperature while the control bits stay in a place where it is easier to manually adjust.

vmstan/gravity-sync: 💫 The easy way to synchronize the DNS configuration of two Pi-hole 5.x instances.
Posted by jpluimers on 2026/01/28
Interesting: [Wayback/Archive] vmstan/gravity-sync: 💫 The easy way to synchronize the DNS configuration of two Pi-hole 5.x instances.
Reasoning: [Wayback/Archive] Frequent Questions: Why two Pi-hole? · vmstan/gravity-sync Wiki
Via:
- [Wayback/Archive] Can PiHole work fine for more than 100k clients? : pihole
- [Wayback/Archive] Gravity Sync, an easy way to keep multiple Pi-hole In-sync – General / Customizing Pi-hole – Pi-hole Userspace
What is better than a Pi-hole blocking ads via DNS on your network? That’s right, Two Pi-hole! But if you have more than one Pi-hole (PH) in your network you’ll want a simple way to keep the list configurations identical between the two. I’ve recently been toiling away at a script to do exactly this, and what started as a few lines lines of bash was shared with some friends, and has grown into what I now call Gravity Sync — which I’d now like to share with you all for your feedback.

NEW Universal USB Type C Mod to Restore your older devices! – YouTube
Posted by jpluimers on 2026/01/22
Nice videos about USB-C receptacles replacement that might fit old mini-USB and sometimes micro-USB ones.
Before applying, check out the tables in USB hardware: Compatibilities – Wikipedia and the table I copied from USB hardware: connector dimensions – Wikipedia to ensure there is enough space to fit the USB-C receptacle in:

Bundling DuPont connectors: 3D Printing Everyday for 365 Days 282/365 #stem #3dprinting #3dprint #ideas – YouTube
Posted by jpluimers on 2026/01/15
Nice idea: [Wayback/Archive] 3D Printing Everyday for 365 Days 282/365 #stem #3dprinting #3dprint #ideas – YouTube
It mentions DuPont wire connectors which is colloquial for a common form of jump wires: the ones that can connect to breadboards, or male or female pin headers. Basically a so called “DuPont wire” is an electric wire with a pin header (either male or female) on each end leading to 3 kinds (not counting ones having multiple connectors on each wire) as male – female is the same as male – female:
- female – female
- female – male
- male – male
Being able to group the connector end of multiple jump wires in one enclosing connector for quick opening and closing is a great idea.
Hopefully the 3D printing files will be released somewhere.
One of the comments is also inspiration for a future 3D printing project:
