Electronics explained in a simple way
A common decision to make for hobbyists and inventors is Kicad vs Eagle.
Both of them are decent programs for designing your own Printed Circuit Boards (PCB).
And both are very popular.
But if you’re just starting out, which one should you choose?
After six months of testing, I am finally ready to give you the result.

Texas Instruments sponsored me to do a challenge and write this post.
What would it be like to not have access to power plugs?
That’s what Texas Instruments challenged me to try.
They’ve built some really nice resources that you can use in your next power supply design, and now they want to spread the word: www.ti.com/power
In the challenge, I could not use any device that was plugged in for a whole day.
So, to prepare for the day, I charged up my two most important devices: My mobile phone and my laptop.
At 6.30 my alarm clock wakes me up. (It’s an app on my phone, so it’s allowed ;) )
Are you a brainiac?
A year ago, I launched Electronics For Kids together with No Starch Press.
Now you can get this book, and a lot of other “brainy” books, for whatever you want to pay!
And – you’ll support charity while you’re at it =)

I just tested Manga Screen!
This is project that started four years ago.
From a hot, tiny room in a small village in Guatemala – I developed the first version of the touch interface for the screen.
The screen was called Manga Screen.

Today, Seeed Studio published an interview with me on their blog.
If you’re curious about the things I’ve done over the last 5 years, check it out. (Hint: Traveling, writing books, doing workshops, creating courses+++)
Seeed Studio is a hobbyist-friendly shop that sells electronics and PCB services. I’ve used them since I started out and can highly recommend them.
I recently got a question about chosing a pull-up resistor value:
Hey!
In Monostable button triggered circuit, why did you connect 10 kΩ specifically? Does it contain any calculations?
You can use resistors for many things. In the following circuit that he was referring to, the resistor R2 is a pull-up resistor with a value of 10 kΩ:
