Electronics explained in a simple way
This email contains a crucial piece of information.
There’s no need to waste time trying to understand how any circuit works before you get this:
As a kid, I tried to see the delay between me flipping the light-switch and the light turning on.
“There must be a delay”, I thought to myself.
“Something has to travel from the switch to the light, right?”
But no matter how hard I looked, I couldn’t see any delay.
The light seemed to turn on exactly the same time I flipped the switch.

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.
