Do This Before You Solder Anything – YouTube

Soldering steps and common problems - Adafruit

Soldering steps and common problems – Adafruit

These are nice references when you start to learn soldering:

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%

MacOS and Windows: sorting – Simple to enter Unicode character that would sort after Z in most cases? – Stack Overflow

According to [Wayback/Archive] What Unicode character is this ?, the above mentioned character is U+0674 : ARABIC LETTER HIGH HAMZA.
