- I suck at darts, but I'm good at engineering,

00:02

which means, (board dragging)

00:04

I'm actually really good at darts.

00:08

(upbeat music)

00:23

(gleefully chuckling)

00:24

Most of the projects and builds from my YouTube channel

00:26

take a month or two to pull off.

00:28

But I've been working on this beast

00:29

with my former NASA coworker, John,

00:32

for over three freaking years, and here she finally is.

00:37

So it's fairly self-explanatory, but you throw a dart,

00:39

and as long as your initial throw

00:41

is somewhere within this diameter or so,

00:43

the dartboard helps out a little bit.

00:46

(board dragging)

00:51

(bell ringing)

00:52

And what's cool is if you use this dart,

00:54

it will make you the world's best dart player

00:57

because you get a bullseye nearly every time,

00:59

and even if you don't, it's really close.

01:00

But if you use this dart,

01:02

it makes you the world's worst dart player,

01:04

'cause it calculates the initial trajectory

01:06

and then moves the board in the exact opposite direction.

01:09

(board dragging)

01:11

(pool balls clanking, background chatter)

01:11

So eventually we took this thing to a bar

01:13

to see if it would work in the wild.
