A first look at the Miniware TS21 USB-C soldering iron after a quick trial, covering heat-up time, portability, and early impressions for electronics prototyping.

Finishing the weather station prototype PCB, testing the assembled board, discovering an OLED pinout mismatch, and investigating reverse voltage through the LDO regulator.

Assembling and testing a custom weather station PCB, including SMD reflow using a hotplate, lessons learned, and early-stage debugging.

Testing cheap hotplates for SMD soldering and experimenting with Sn42Bi58 low-temperature solder paste.
