Third time lucky? It's time to give SMD soldering another go with another new toy. This time, it's a hot plate. Well, actually, two hot plates. One tiny one, and one slightly ess tiny one. It wasn't as easy as I expected, but isn't that always the way?

https://jlcpcb.com/?from=JohnThe PCB being built in this video is my new camera trigger design. It's based on the intervalometer I built on a breadboard in 2020, although some of the components have been upgraded. The ESP8266 has been upgraded to an ESP32-S3, the DS1307 has been switched out for a more accurate DS3231 and the two 4N25 optocouplers have been swapped out for a single TLP291-4 quad optocoupler IC.
If you didn't see my DIY intervalometer build, you can watch it here:
