I'm a new member and just recently happened to see a build thread on an ESR meter. In the thread was a link to a new updated project along the same lines. Unless someone makes a new post these kind of things just get lost in a few months. I'd like to see as perhaps a subsection to the Open Source Hardware, a listing of these threads, or maybe just one post with the basics of the project and a link to the original thread. Something like the ESR meter is a simple build and you get a useful tool at the end.
I'm not sure if this would need to be subdivided or if even the forum section is the correct place. A home brew site I know does kind of the same thing with recipes. Some possible subsections would be test equipment, audio, robotics, whatever.....
Basically, just something to keep these projects easy to find in case someone is interested or just looking for something to build. There is probably plenty of projects archived in threads here already. I'm sure members can make suggestions about which past projects are worth being brought to the foreground and how to categorize them.
Off the top of my head here's how I would do it. I'd have someone do a new write up on the completed project. Schematic, PCB layout, pictures and perhaps a rough difficulty rating. Beginner, Intermediate, Advanced. At the end the original thread could be linked to for any discussion. Lock the post so it can't be discussed in the subforum. I'd think keeping this section clean would make it easier to navigate. The point is to build a database of some useful/fun open source projects that people can easily browse.
