#introduction Hi, I'm David a 50 something geek who should have written this a while ago. I work for Ocado doing geeky things. In my spare time I work with the https://www.under17-carclub.co.uk to teach children how drive safely before they get on the roads. I regularly make my kit car more unreliable by throwing #ESP32 devices at it and fiddling unnecessarily with its #speeduino ECU. For my sins I'm also an author of #MSDroid tuning software.
