About two years ago.
Norway isn’t a very sunny country, so when the sun is shining I need to take advantage of that.
So I made myself a little wall of cardboard to protect my laptop screen from the sunlight. This way, I could sit in the sun while working.
I was working on the firmware for an HDMI touch screen.
The USB protocol was new to me, so I spent a lot of time reading about it…
…then testing out what I read, using the open source library LUFA.
And the result was the Manga Screen (www.thing-printer.com/product/manga-screen/)
If you want to build your own custom USB gadget, here are the steps you need to take. I’ve added links for more info on each step:
1. Learn basic electronics and start building some circuits:
2. Learn to use a microcontroller:
3. Learn how the USB protocol works
4. Learn to use the LUFA library:
Keep on Soldering!
PS! My eBook “Getting Started With Electronics” will teach you to build electronics from scratch. A good way to start if you found this email a bit too advanced:
