Electronics explained in a simple way
Yesterday I climbed the hill of three crosses.
It’s a popular hill in Medellin for doing a Sunday hike.
Green and beautiful.
When you get to the top, it’s a great view of the city.
Suddenly I’m seeing new things:
“Oh, there’s a golf course over there.”

I remember something I struggled with in the beginning.
The LED.
It’s supposed to have a fixed voltage drop, right?
Like 2V.
But what if I force 3V across its legs with a 3V battery?

This has been a fun year.
It started out with me taking on a new electronics project.
Which was a bit challenging because I needed to use the new Bluetooth 5 chip nRF52840…
…before it was even officially released!
A very cool experience that pushed my electronics skills further.

Watching the little, yellow bird outside our window.
I came across this paragraph:
what you hear, you forget
what you see, you remember
what you do, you understand
I want you to understand electronics.

On Christmas eve, instead of watching movies and eating candy during the day, we went to a poor neighborhood in Medellin.
Some friends had collected toys.
And we helped give them out as Christmas presents to kids who might not otherwise get anything.
The kids were really happy.
And we got to see a part of the city that we would never have seen otherwise.
With an amazing view!
