And this speed, combined with today's high-performance micro-controllers,

ื•ืžืžื ื•, ื”ืžืขื‘ื“ื™ื

my father and I are working on a new patent-pending design

ืื‘ื™ ื•ืื ื™ ืขื•ื‘ื“ื™ื ืขืœ ืคื˜ื ื˜ ื—ื“ืฉ

for a fully volumetric display using the same phenomenon.

02:07
It achieves this by rotating LEDs about two axes.
32

3000
ื•ื–ื” ืžืฉื™ื’ ืืช ื”ืชื•ืฆืื” ืข"ื™ ืกื™ื‘ื•ื‘ ืœื“ื™ื ื‘ืฉื ื™ ืฆื™ืจื™ื.
02:10
So as you can see here, this is a, eleven-inch diameter circuit board.
33
130330
3000
ืื– ื›ื• ืฉืืชื ืจื•ืื™ื, ื–ื” ืœื•ื— ืžื•ื“ืคืก ื‘ืงื•ื˜ืจ 28 ืก"ืž.
02:13
These blocks represent LEDs.

ื”ืจื™ื‘ื•ืขื™ื ื”ืืœื” ืžื™ืฆื’ื™ื ืœื“ื™ื.
02:15
And so you could see that as this disc rotates about this axis,
35
135330
4000
ืื– ืืชื ื™ื›ื•ืœื™ื ืœืจืื•ืช ืฉื›ืฉื”ื“ื™ืกืง ื”ื–ื” ืžืกืชื•ื‘ื‘ ืžืกื‘ื™ื‘ ืœืฆื™ืจ ื”ื–ื”,
02:19
it will create a disc of light that we can control.

ื”ื•ื ื™ืฆื•ืจ ื“ื™ืกืง ืฉืœ ืื•ืจ ืฉืื ื—ื ื• ื™ื›ื•ืœื™ื ืœืฉืœื•ื˜ ื‘ื•.
02:22
That's nothing new: that's a propeller clock;
37
142330
2000
ื–ื” ืœื ื“ื‘ืจ ื—ื“ืฉ, ื–ื” ืฉืขื•ืŸ ืžื“ื—ืฃ.
02:24
that's the rims that you can buy for your car.
38
144330
3000
ื–ื” ื—ื™ืฉื•ืงื™ื ืฉืืชื ื™ื›ื•ืœื™ื ืœืงื ื•ืช ืœืจื›ื‘ ืฉืœื›ื.
02:27
But what is new is that, when we rotate this disc about this axis,
39
147330
5000
ืื‘ืœ ืžื” ืฉื—ื“ืฉ, ืฉืื ื—ื ื• ื™ื›ื•ืœื™ื ืœืกื•ื‘ื‘ ืืช ื”ื“ื™ืกืง ื‘ืฆื™ืจ ื”ื–ื”,
02:32
this disc of light actually becomes a sphere of light.
40
152330
3000
ืขื›ืฉื™ื•, ื”ื“ื™ืกืง ื”ื•ืคืš ืœื›ื“ื•ืจ ืื•ืจ.
02:35
And so we can control that with micro-controllers
41
155330
2000
ืื– ืื ื—ื ื• ื™ื›ื•ืœื™ื ืœืฉืœื•ื˜ ื‘ื–ื” ืขื ืžืขื‘ื“ื™ื
02:37
and create a fully volumetric, three-dimensional display with just 256 LEDs.

ื•ืœื™ืฆื•ืจ ืชืฆื•ื’ืช ื ืคื— ืžืœื, ืชืœืช ืžื™ืžื“ื™ืช ืขื 256 ืœื“ื™ื ื‘ืœื‘ื“.

ื™ืฉ ืœื™ ืกืจื˜ื•ืŸ ืงื˜ืŸ ืœื”ืจืื•ืช ืœื›ื,

ื•ื–ื” ืจืง ืขื 4 ืœื“ื™ื.

So, take a look.
50
185330
2000
ืื– ืชื‘ื™ื˜ื•.
03:09
And here you can see it's rotating about the vertical axis only, creating circles.

ื•ืื–, ื”ืฆื™ืจ ื”ืฉื ื™ ื ื›ื ืก ืœืคืขื•ืœื”,
