I always like the smell of the fluxed solder, but it's the lead fumes that are the problem with leaded solder - avoiding the neurological damage exacerbated by breathing in the fumes is the main issue. But I have to agree that lead-free solder is a right pain to use. Nice instructions in the video, though 👍
My kit just arrived Alex. Looking forward to putting it together once my daughters are sleep! Thank you. Great video by the way. Particularly interested in your covering Arduino as well as the Pi for this widget.
Cool. I hope to get some of that done over the summer. But I do need some time off as well. However, if you want to get a head-start on things, the FastLED library github.com/FastLED/FastLED is the one I use for arduino and Wemos. I will document it at some point, but in case you're impatient to get going... :)
