Guy builds amazing automatic dartboard

As each round of darts goes by at the pub, and your blood alcohol level starts to slowly rises and your chance of hitting that fabled bullseye diminishes.

That's unless you're playing with ex-NASA engineer, Mark Rober's board. This thing is crazy!

Mark spent three years building this beauty, and it's an absolute work of art.

If you aren't too flash on the old board, and have a couple of years worth of free time, build one of these bad boys and you'll have the best man cave in the land.
