Hi!
In my YouTube channel I talk about my hobbies; rockets and electronics. From time to time I implement a circuit following a design from the Analog Devices website, or fly a rocket and make a video about it. Here is an example
of a heart rate monitor that I built.
I have also designed a flight computer for rockets
https://www.tindie.com/products/25820/ that I have been selling in Tindie. It is amazing how far PCB manufacturing capabilities have gone that nowadays a hobbyist can bring a product to market on his own.
Anyway, I'm open to ideas and suggestions for future content.
Cheers!
