My hair is getting too long so I decided to build a robot to cut it for me. To support future projects like this check out my patreon:   / stuffmadehere

The possibilities for this kind machine are endless with the most interesting things being haircuts that are too hard for human hair cutters to achieve. Imagine a mathematically perfect fade from one side of your head to another. Or imagine if I added a trimmer to this and cutting perfect lithopane pattern into your hair. I consider this the first generation machine and hope to build another to explore some of the crazier haircut concepts. A colleague suggested adding a precision hair dying attachment and doing some crazy multi-color hair styles. I wouldn't say that's really "my jam" but I might try it in the name of science & engineering.

This isn't just limited to humans either. Imagine sticking a poodle in this or making a bigger one to create topiaries. Lots of fun ideas....
