And of course you can publish it (might be good for feedback), just state that it's a learning journal, not "best practices".
The reason I'm saying that is that human beings have selective memory. They tend to remember things they did the right way, they remember their good ideas, times they were right, etc.
I used to note my ideas that would seem genius.. And then I'd look at them a couple months later and it's humbling. How stupid could I be.
But there is a good thing about this: It taught me a valuable lesson.. It taught me to focus on real needs, and not some fancy thoughts I have at 3AM. Like real needs.
And I know that at an early stage, one needs to let go of critical things and be open and not dismiss ideas, etc.. But it's just that some ideas are plain stupid and I had plenty of those.
I write them down, then cross things. Not a real need, not a problem. Now I'm thinking about an idea that I'd use if it were available. And I'm not the only one.
This is a project I did a couple of years ago

This is another project :

There was an update on the site, so images are not available there.. Here they are:

Bear in mind that this is what my first attempt with PCB design was [PDF] in French, but you can see how ugly it was:
I was on the forum chat, and I'd send pictures and they'd help me see, they'd open my eyes and explain things. Why 90° tracks are a no-no, etc.
People are tremendously generous with their time as long as your attitude is okay. I learned orders of magnitude more on the internet than in college, and still do every minute I'm online.
