Instead of doing a date based projects instead do point-based. The difficulty will be based off; size, number of parts, time took to actually work on the project. Each simple project gets 1 point. The complex project gets 2 points. Expert projects get 3 points. Effectively the idea is each mechanic is worth a point expect the easy stuff like, "click button" it has to be something YOU code and took some time to code. Something more akin to a dice roller. I'll make myself project bounties for big projects. I wonder if others will try this method?
