Hi,
Bit of a late reply but better late than never
Can I please first suggest that you change the date system to Australian format instead of American. It's driving me insane. I keep wondering why this post was made on the first of December?!
I think tutorials and a sense of community are the key. The only times I have ever spend an extended period of time going back to the same site time after time was if there were useful tutorials, or if I knew there were people around who could help solve problems.
Tutorials that are easy to understand and relevant are mega useful. I say relevant because while I might find your tutorial about the advantages of high power lasers over low power lasers in laser etching interesting, I will probably never use it. Things like setting up a UV light box to make your own PCB's, or writing motion detection software for a simple camera I would definitely take a longer look at and maybe even use.
Also a good knowledge base is good too (as I see has been started to be set up). General information should be put in there too. And I include here pretty basic stuff like; how pull up/pull down resistors work, how do transistors work, etc, as well as more in-depth things like H-bridges and stepper motor controllers.
Guess what I'm saying is that there should be basic information, as well as some more advanced stuff around. In addition there should be a good forum community to ask questions about those specific things that no tutorial or guide will ever cover. Also love to see what other people are doing
Let me know if you agree or disagree with anything.
I have been looking for an Australian site like this for a while so I'm glad to see things are happening.
