Have no fear... even if this project sounds complex, you'll easily learn in this article many things about high speed electronics and PCBs.
In fact, my goal here is to teach you some basics about all the new problems that arise when you're dealing with GHz signals .

Yep, for the first time this will be (mostly) a code article .
But if one day you want to make a Hi-Speed (480Mbit/s) USB composite device with CDC (communication) and MSD (mass storage) classes, this is the post you'll want to read.

If you are ordering your projects' components on digikey... this is the script you have been missing!

Let's imagine that, for some reason, you'd like to create a 4+ layer PCB, and that free tools such as eagle or kicad aren't enough for you (let's say for high speed PCB design or complex schematics).
You'd then have to choose between the two (but not only) major softwares available now: Altium Designer or Cadence Orcad Suite.
This is therefore my opinion about them.

3 months after having set the solar platforms in an indoor environment, I'm happy to show you here the extracted data

After a rather cloudy month, I finally extracted the logged data from my 8 platforms. So let's see what we got here...

Yes, this project was a lot of fun .
As I had to disassemble my Acer Aspire One to replace its hard drive, I decided to do a couple of other modifications....

Hey guys, I just came back from a trip to China! Not only was it an occasion to visit this vast country but also a good opportunity to go to the numerous electronics markets in the cities of Xi'an and Beijing. Yes, even on holidays I'm still into electronics .
So here are the few interesting things I brought back, and especially what I did with them...

It has been quite a while since I wanted to write something about my experience in product creation, especially the "what to do(s)" and "what to avoid(s)" for those who would like to do the same things as me.
I'll thus write here some tips and advices that you need to keep in mind at all times when designing your own product. Please read, these tips might save your life at some critical point during the usually complex design process!

It has been quite a long time since I last posted a project on this blog... for the good reason that I am going to detail here for you guys!
So in this article you will see a quite complex project I have been working on for at least 6 months, which is an Engine Control Unit (ECU) monitor...
