Tay Tay Nay Nay to the Solder Fumes

While 96% of Australians lined up recently to spend their hard earned cash on Taylor Swift's Eras Tour, I retreated to my dungeon and re-vamped the solder fume extractor I'd been relying on to keep me safe over the last few years.

The journey involved a new "soft-start" circuit and some laughs with interruptions and other snafu moments.

It was a very good result in the end, but oh my what a journey.

The worst part was that when I emerged triumphant Taylor was still singing her heart out in Sydney!

Your thoughts, as usual, appreciated!

TDA1308 Microphone Amplifier Board

A few mailbags ago I unearthed a little red board that I initially thought might be an amplifier (the "TDA" label is usually a big hint!)

I was correct in that it was an audio module, but the little microphone in the corner was the clue that this board was a microphone plus amplifier.

After fruitlessly searching for an appropriate library I did a little "roll your own" code and found out that it works well! See for yourself in the video below.
