It's a definite "No" for me.
It doesn't pass the smell test for me to solicit donations to help pay for keep the site running and then pay out money for posting a project. No one came here to make any money.
As some others have commented, maybe there needs to be ONE place to put project. Right now they are everywhere - Shop Made Tooling, What Did You Do In Your Shop Today, and now there's a new one - Post Pictures of Your Projects (or something similar). Not to mention all of the projects / rebuilds / refurbish threads in the Forums for different brands of machines.
I'm not sure what drove the question, but I think there ARE a LOT of projects all over this site. A lot of times when a question is asked, a response will be "this is what I did" and show a picture that may show a "project" previously done but not documented and posted. We're all hobbyists and and we all do projects. Most of the time we don't feel they are significant enough to share with others.
I think when someone DOES post a project, we could all do a better job following up with positive comments. I know it's frustrating when someone posts a project and gets a lot of views but not many comments.
My two cents.
