Electronics explained in a simple way
One of the things that I love about being able to build electronics is that I can also REPAIR electronics =)
I often get the question:
“How can I learn to repair electronics?”
My response is:

The resistor and capacitor on the left of the inverter make up an RC delay element:
But how does the current flow in this circuit?
Can I comfortably fit the components for this project on my protoboard?
That was the question I asked myself in my early electronics-building days.
If I couldn’t, I regarded the project as “too hard”.
Often the most exciting projects are much larger than the simple ones.
It’s not that they are a lot harder.
But the big circuits have a lot more connections.
And more connections = more chances to make an error.
Which can be scary.
It wasn’t until I learned to design my own printed circuit boards that I stopped being afraid of the bigger projects.
A printed circuit board, or PCB, is a board that you first design on your computer. Then you get your board made, with the exact connections you drew on your computer.
The great thing about this is that you can draw out the connections on your computer. And you can peacefully check that they all seem good up front.
Then later, when you have your board, all you need to do is make sure you solder each component in the right position.
No need to worry about the connections between components, because you know they’re correct.
This skill will make your life a whole lot easier.
It’s what’s gonna take you from just building simple circuits – to be able to create advanced gadgets like LCD screens, Quadcopters, etc.

And it’s the start of the weekend.
For many of us, that’s a chance to carve out a big chunk of time to work on a project.
Today, I set aside some time to browse the web.
Looking for fun projects that people are building.

It’s a question that regularly pops up in my email.
It usually goes something like this:
“How do I choose components for my circuit?”

I wrote this email based on a recent event.
And maybe it can help you.
I’m developing a new series of electronics lessons.
(I’ll send them to you when they’re ready)
