Re: Pi in the oven
@Michelle, I have nothing against a general learning machine (I've got a couple of old laptops that fill that role) but I find that it's easier for me to gain inspiration from projects than it is to come up with new ideas on my own. That may be a weakness on my part, but I do love having a project as a starting point.
One of the things that's not on this list is a big-screen microscope. I've been looking at several of those projects -- I think I'll have to do my own article when I finally choose a design and put it together.
