A platform where tinkerers exchange their half-finished projects with others who are willing to finish them on Youtube for everyone to see.
With time tinkerers amass loads of parts and components for various projects. Some of which never get completed because people lose interest, procrastinate, and move on to new projects.
Half-finished projects clutter the tinkerer's work and/or living spaces because they theoretically plan on completing them someday.
Having the clutter removed from your spaces and seeing your old projects completed by someone else is not bad either.
If you're a tinkerer, chances are you have a few half-made projects laying around and cluttering your place for ages.
Similar to how people share ideas for which they don't have time to build, I propose that tinkerers (builders, engineers, etc) pass on their half-built projects to others who are willing to complete them.
There would be a platform where people post their unfinished project's photos/videos and description. They explain what they were going to build, which components they have, how far they got, what's left to do, what knowledge they can pass to the person willing to complete the project, etc.
Depending on the value, the person may list the project for free or with a price if the parts were expensive.
People then bid on the projects.
Feedback and reviews are mandatory. A person's track record determines whether or not they will be selected to take on other projects in the future.
By bidding they commit to video document the build process and share it on Youtube within a deadline they themselves defined. The project owner then selects whichever bidder was the most convincing or suitable to take over.
They deliver all the parts/knowledge to the new builder.
