(bouncy music)
- I feel like I've been asking this a lot lately
but, does this work?
- Oh yeah.
- Wait a second.
- How are you doing that?
- Doing what?
- This is a flat panel TV.
- Yeah.
- That's a light gun.
- Yeah.
- Well flat panel TVs don't work with light guns.
- Works with this one.
Wanna try it?
- Absolutely, just like I wanna tell our viewers
about our sponsor.
This is the new Vengeance, a4100 streamer PC from Corsair.
It's powerful, it's beautiful and you can pick it up today
at the link in the video description.
(fast-paced upbeat music)
So why is it that light guns don't work on modern displays?
The reason is that traditional light guns are designed
for use with a CRT style display.
Where a beam of light scans back and forth across the screen
so quickly, that it tricks your eyes into thinking
that they're seeing a complete picture.
If you've ever seen a flicker effect on a screen
in a video game or an old TV broadcast,
that is what you're seeing.
- Because that beam is highly visible at any given instant,
the light gun can check to see exactly where it's pointing
the moment the trigger is pulled.
And on the old NES, Nintendo went a step further by turning
the screen black for a single frame
and the target painted bright white.
And would repeat that for every target on the screen.
This way the console can count which line and even
which pixels, the link gun was pointing at
at the instant of the trigger was pulled.
- Now modern display technology along
with being totally different compared to how a CRT operates,
also has LED.
In order for the console CPU to count the lines accurately
with what's being displayed on the screen, it has
to be precisely timed.
Something that was possible with a CRT
who's very ability to output relied on syncing
with the console, but is not possible on a digital LCD.
So the Sinden light gun here is something truly special.
And the moment I laid my eyes on it, I absolutely
had to have one because as you can see
it works just fine not on just a modern TV, but even
a state of the art OLED TV.
And presumably, any kind of display.
And that's because it uses a novel method
for detecting where the gun is pointing
at any given moment, a camera.
Now, you might be thinking that this is basically
a glorified Wiimote and in theory you're not wrong
but in principle, there is a lot more going on here.
This camera runs at 60 frames per second
and the processing delay between moving the gun
and moving the cursor, is as low as one millisecond thanks
to some clever mathematics and software
that runs on both Windows and Linux including
the Raspberry Pi.
- At least in theory, it should essentially be a one
to one cursor movement with the gun.
But because it's set up to mimic a mouse, you don't need it
to figure out exactly which scan light it's on when you pull
the trigger the software just already knows.
Plus, if the application supports multiple mice
like Mame, you can use two or more at once.
There's even an optional recoil effect upgrade
that works without an external power supply like
most light guns otherwise would need,
but our pre-production unit here doesn't have that.
- You might have also noticed that we don't have two of them
to have them to try multiplayer so, you got to use it
in the intro which means, it's my turn now.
Oh, that's a very unsatisfying slight action (chuckles).
So you wanna be about what was it, one and
a half, screen widths.
- Yeah, one of the half screen widths
is the optimal distance.
- Okay, so this probably about right about right, boom!
- It about right.
- It's good. - Yeah, like there's no lag.
- [Linus] Right, holy crap that one was fast.
I Wouldn't even guess that this was only 60 hertz.
I'm actually very surprised to hear that.
- Well at 60 hertz there's processing going on,
there's probably some interpolation going on as well.
Andy Sinden the creator of this thing
didn't actually tell me if there's anything special going on
with the processing, just that it's a lot
of really complex maths.
- I don't even remember being this good at this game.
- No, me neither.
- I'm feeling like a sharpshooter right about now like, wow!
And it's just a camera
on a gun. - Camera on a gun.
- [Linus] All the software wizardry is probably
why this thing has taken so darn long, for them
to come out with.
- Yeah. - How long this been
in development like couple of years?
- I think so, we've been kind of waiting to get it
for about a year.
- What's the pricing?
- I think it's 149, let me quickly triple check that.
Oh, sorry it's-- - No I missed one.
C'mon, shut up dog.
- It's 80 British pounds.
- Okay, so like hundred bucks US--
- Hundred bucks US yeah. - Okay.
Good. - Yeah, you're not perfect.
Not around 10 you not. - Okay.
That's fine I'm gonna be perfect around 11.
I'm not gonna waste a single bullet, shoot.
- Proceeds to waste two bullets. (Linus chuckles)
- Now they've got some other features built in there's
a D-pad on the one side.
- Yap. - And I've actually
got two buttons on each side.
- Each of those buttons can be... (laughs)
Each of those buttons can be mapped to something different.
So right now the reload slide and one of the side buttons
on the left I believe the one closest
to the D-pad is reload.
Left on the D-pad is escape, down on the D-pad is enter.
And the back two on the right--
- No, (shouts) sorry.
- That's okay. - What the buttons do?
- [Anthony] The back to on the right are currently set up
for, auxiliary functions.
So in that account they don't do anything.
But in the arcade games they are used
for things like in inserting coins that kind of thing,
it all varies by game.
Oh that's a game over.
- Okay so then if I wanted to, what just happened?
I just started the game again.
- Yeah, you pressed I think you pressed down on the D-pad.
And then you press back to the left on the D-pad
which is escape, which is closing the emulator.
- Oh, I just assumed this would be like, arrows.
- No, not in this case it's not set up like that.
In order to change the selection
on Duck Hunt, you pull the trigger.
- Got it, okay.
So how do I go to House of the Dead I wanna play
some House of the Dead.
- You point it at the screen.
- Oh that makes sense (whispers).
Look at that boom, boom, boom, boom--
- Yeah, it's even capturing little motions
in your fingers, your hand.
- Sure is wow, I thought my hands are pretty steady
but I guess not, aye.
- Well, (laughs) it's not terrible.
- Yeah I see that well maybe if I hold it sideways, right.
And like get a bandana, and it'll be steadier.
- Well, gangsta mode is a thing that's built
into this thing.
- Oh wait, yeah wait does it, yeah it is too.
- Yeah.
- It knows which way it's oriented.
- Yeah, so the back right button
will enable your border which your--
- It's that right here?
- On another side, yeah. - This one.
- [Anthony] That will enable the border, which is required.
- What the, am I like dying already here?
This is too hard, I'm dead, I'm already dead.
- It's the House of the Dead so, it's fitting.
- So why don't you tell me about the border a little bit.
- Basically, that's what the camera is looking for.
You can configure the size and the color of the border
and depending on your TV brightness, the TV itself,
the background brightness and the angle you're using it at
it can either be thicker or thinner.
But if you have a lot of sunlight coming
in through your room, you're probably going to have
to adjust either the thickness or the color of the border.
And there is some image recognition built in there
and whatever color you set the border to, it
will actually look for.
So you can see what it thinks the screen is.
And as you back up it actually fills the screen.
- Yeah, well that's probably because of the kind
of fisheye style lens so you can actually see
the distortion-- - Yeah, yeah.
- [Linus] of the screens so that's why they want
that distance 'cause it needs to be kind of within
some field of view of the gun.
But they can't have a narrow field of view because,
otherwise you might risk losing track of the edge
of the screen when you shoot off to reload or whatever.
- And there's also this down here
which is kinda interesting as well, Show Raw Video.
- Oh, okay so I can click that here.
Oh look at that, now we can really see Anthony
there he is.
- lttstore.com.
So that's the raw camera.
That's what it looks like processed into basically
a one vid image.
- And where is the processing done?
- It's on the CPU.
So this rather poor CPU is currently being utilized
to the tune of about 36, but that's actually only
because we're showing these images.
If we turn those off, it'll be down to about 20 ish percent.
On a modern system, with a powerful CPU it's pretty much--
- There's a dual core what, second gen i3.
- Fifth gen, but it's a low power one, 2.1 gigahertz.
- Yeah ouch, a modern gaming CPU has a single core
that's like 25% more powerful than that.
- Not to mention all of the like architectural benefits
of newer machines.
- I don't think there's much since fifth gen (whispers).
(Linus coughs)
- Here we've got the offscreen Reload, we can turn that off
if we want to.
Edge Auto Reload, he actually disabled because he found
it very annoying.
Basically reload is right click.
- Yeah. - So if you go to the edge
of the screen, it would start like right clicking.
- Okay border, so here's where you configure
the border we were talking about.
- Yeah and for the border you can see that it's got
a couple of options here.
The primary border in this case is the black one.
So it would cut off about 15 pixels.
Same with the secondary border here which is set
to white pixel with 15.
We can say we can change that color if we want to.
The filter radius is what the camera actually thinks
is that color, so you can increase it if you have like
a TN panel or something like that.
You know the viewing angles don't skew it too much
so that you lose tracking.
Here we have cursor offsets.
Not every game the cursor is pointing spot is like exactly
where the cursor is.
So you can set offsets in this case.
- So, what's availability like 'cause it sounds like
this is kind of a small one person project.
- It kind of is, it started on Indiegogo actually.
There's a website setup for it now
and from what I understand it's under production now.
So this is a pre-production unit, this is how
the final ones will look.
- Feels pretty good to me. - Yeah.
And the final ones also have
that recoil action solenoid option as well.
I mean it seems like it's pretty good, the guy
has been responsive both to me and to people
in the community-- - Go check him out.
- [Anthony] Which seems like a bit of a passion project.
- We'll have them linked down below.
This is really cool like I want one.
- Well, I mean you have one now.
- Yeah, but like I want
the recoil one. - Oh
- [Linus] Yeah, and two. - Yeah.
- [Linus] Yeah.
- Yeah. - Oh can you get a red one?
- [Anthony] I'm not sure if they come in red they may--
- Please tell me they're not all blue.
- The only images I've seen of them have been blue,
,but then again, that's all been pre production up to now.
- Yeah, let them know if you wanna see two colors.
You gotta have two different colors (whisper).
Have the alpha and the beta color.
- Right - Like one color
for your friend who came over and then there's one for you.
- Yeah, which one are you blue or red?
- Oh, I'm the blue guy.
- Oh really?
- Yeah blue player works, I don't pick
the rules I like red better but like, blue's player one.
