alt Hacker NewsI tried soldering. With a TS100 (might have been a TS80P). I tried to solder a a Valetudo Dreame adapter [1]. Took me two hours, then I gave up. I attributed it partly to my unstable hand. Next day I tried to make a USB to (I think) TTL cable. Also failed, the cable wasn't reliable. The fumes were horrible, probably inhaled a lot. I ended up borrowing an adapter, and easily succeeded rooting the damn thing. Never again (the soldering, not the rooting). Same with cable crimping. These physical things are just not my cup of tea. I got two left hands. I hate soldering.
Try rosin flux, it smells actually pleasant!
A lot of initial soldering mistakes are from using incorrect temperature, not cleaning the surfaces with flux, or from using wrong tips.
You do get better rather quickly, especially if you ask for help!
