content: Hi, would like to buy some cheap bluetooth earphones from Aliexpress, however cheapest ones come with micro-USB. Since I want to have a single charger for all and no adapters, could I open the charging case, and replace the connector?Something like that:https://www.aliexpress.com/item/33011860929.htmlhttps://www.aliexpress.com/item/4000339760924.html

Anything more, and you need to get into more complex designs.

(I didn't realize YouTube had this level of localization, but a quick search led me to a help page on how to do it.)Looking at his channel, it appears to me he's a Turk living in France, which would explain the glorious grammar: "it is hack?" (Yes, is hack.)

Whenever I scrape silk to expose a copper plane, I start out with a hobby knife which already takes some careful handling. But it's fast, much faster than using the correct tool for the job (i.e. fiberglass pen), and the result is never nicely flat. Getting the exposed area tinned is hard because the solder flows very poorly. A few seconds touch up with fiberglass pen results in a much smoother surface and the solder attaches much better.
