Hack your usb missile launcher into an "Auto-aiming autoturret!"

How to make your usb missile launcher aim on it's own.
This instructable will teach you to turn your usb missile launcher in an autoturret which will find and aim at IR targets. (sorry only IR targets)

Step 1: What you need!

What do I need?

You need:

1 wiimote:
a bluetooth enabled pc
1 Usb missile launcher (duh!)
Ducttape
GlovePie (Programmable input emulator) You can download glovepie from: http://glovepie.org/poiuytrewq.php
A little bit of programming experience (not really necessary but, helps you understand the programming part better)

Step 2: Preparation

Use ducttape to fasten your wiimote on the top of the missie launcher. Make sure the missiles are still able to fire. The wiimote should point forward, and be placed in the middle of the missile launcher like on the picture. Be sure not to cover the 1 and 2 buttons on the wiimote, because you need to be able to press them in order to connect them to your PC (see next step).

Step 3: Connecting the Wiimote

Now connect your wiimote to your pc. If you already know how to do this, you can skip this step.

If you are using bluesoleil do this: Open bluesoleil and press the red/orange ball in the middle of the screen, this will make your pc scan for bluetooth devices. While your pc scans, press and hold the 1 and 2 buttons on your wiimote (the LEDs should now start blinking) when your computer finds your wiimote you can release the buttons again. The wiimote device should appear on your bluesoleil screen as something like "Nintendo RVL-CNT-01" or something like that. Now double click the new wiimote device your pc found. This will make it scan for possible services. The mouse icon should now turn orange. Click the mouse icon. If the wiimote icon turns green you have successfully paired your wiimote to your computer.
you mean to combine the three scripts right?
Where can i get a launcher like this besides ebay?

I have a Lego Mindstorms 2.0 kit. Just wondering that because it has a IR function on it could the turret track the mindstorms brick??

This would be cool if you put an ir led on a rc helicopter and try to outfly the launcher
Just a thought but maybe you should take this down as people may use this for criminal reasons (aka strapping it to a real gun, etc)
It can only aim at things that emit infrared light, so unless a criminal goes around taping infrared LEDs to people they cant use it for any illegal purpose. They would also have to carry around a laptop doing all the controlling, and create some sort of device to hold a real gun that can communicate back and forth between the computer. The possibility of a criminal doing all that is very low.
Unless I'm being dumb, the target doesn't need to emit IR, it could reflect IR. Just like laser guided bombs or missiles work. The LGB or LGM steers toward the basket which is the cone of reflected laser light which is aimed at the target by the aircraft or special forces target designator. Of course with laser designation, the laser has to be encoded (presumably not too different from IR used in a TV remote control), so that the bomb or missile doesn't or shouldn't look for the sun or a reflection of it, or any other strong IR sources. My old TV used to be confused by the IR emanating from a compact fluorescent light bulb, the new TV doesn't (old TV didn't use encoded commands and was designed before CFLs, new one does and is unaffected by CFLs). So an IR laser or collimated IR beam would do the trick. But the comms link could defeat many criminals.

It's amazing what you can learn from TV!

If a criminal is smart enough to crack the computer / gun comms link, then they wouldn't bother with this! They'd be into bot nets and DDOS attacks and big time extortion to get rich. No-one with any sense is going to use this to control a firearm to commit a crime. Firearms are too heavy and recoil. It would need to be thoroughly re-engineered. It's far simpler to pay someone to do the dirty deed.

All that hoopla aside - great Instructable!
If you want to be really old school with tv remotes you need to forget about IR completely! We have a TV that uses ultrasonics in the remote to communicate with the TV.
zenith right? no batteries. just the sound made from the metal inside the remote being hit. Still would've been great today no betteries needed.
Nope afraid not! It was some old B&O tv, the batteries it uses are near enough impossible to find now.
what kind of battery?
oh well zenith made one that just used the high pitched click of the metal. it was featured on hacknmod.com contest guess the thing.
any idea why this became obsolete? (other than the likelyness that it could change the channel if you drop the remote and it would interfere withe other peoples tvs)
just the fact that newer technologies produce ultrasonic sounds that would interfere with the television. Like do you hear the high pitched whines and sounds when you turn your tv on. would interfere. lol it would be a cool experiment to do.
Yeah it does sound cool, but I guess it was impractical to make (PCBs can be made for next to nothing, where as this sounds quite complicated to make), plus I guess it will wear out eventually.
Great. now some criminal's gonna set that up on the side of a highway and kill anyone in a silver car...
IR led throwies!
i had the same kind of idea. just make a bunch and give them to people or throw them at them. they will likely not know what it is, they will probably look at it for long enough for the missile launcher to find them! mwahaha
Hahahahahaha nice
oh, a thought popped into my head.. oh yeh, what about termal imaging cameras they work on infrared light emmited from the body.
Yeah that's what I was thinking.
Nobody emits infrared lol. Thermal cameras display thermal energy that is emitted from heat, ie: the heat your body gives off.
thermal energy is emitted in the Infrared wavelengh, think of it as very very red light that you cant see.

That's FAR infrared though, it's at a much longer wavelength than the NEAR infrared that standard sensors pick up.
No I'm thinking of a criminal at their house waiting for the police to show up.
Still, the police would need IR LEDs on them, the wiimote can only see relatively intense IR. Also, the IR LEDs have to be pointed within a certain angle dependent upon the LEDs for the wiimote to see the IR. You wouldn't be able to just put a single IR LED on someone and expect for it to work, LEDs dont emit the same intensity light 360 degrees in a sphere, they have certain angles where the light is more or less intense at. That's why trying to play your wii from the side doesn't work well, the wiimote can't see well without pretty much a straight on view.
firstly I can't see many reasons why someone would choose to trust their attempts of murder to a wiimote its just silly. However not as silly as adamvan2000's claims that paper is fun.
seriously, who ever heard of a "usb gun" anyway?
Wow.... That's just like saying one shouldn't use paper because it might be used to write plans for an atom bomb, or something. It's a fun, harmless toy. If someone has the know-how(and desire) to link this to some sort of weaponry, then chances are this instructable being here or not being here would not be a factor. They'd still find a way to do it regardless. Just like a knife, it can be used for cutting steaks or cutting off body parts. It's the intent of the user. That said, excellent 'ible. I really love the (unique)marriage of two commercial tech products. All you need is a sighting laser to make it extra freaky. I can imagine someone seeing the laser tracking an IR emitting source and freaking. ~adamvan2000
seriously if someone is demented enough to do that they're gonna do it if there's an Instructable or not. it'd be fun to put some IR lights on a toy car... drive it around, try not to get hit good Instructable
cool
That is one of the dumbest requests ive ever heard.
I don't think they could do that really. This is a USB controlled device and most people who have a gun could do this anyways.

will this work with the think geek one?

This one? http://www.thinkgeek.com/geektoys/warfare/8a0f/

Well the missile launcher itself should work the same way, but maybe the software is different and you might have to tweak the code a bit, but it should work fine.
what one did you use?

Hello I have an ideo you can get some face detection soft ware for the computer than put camera instead of a wii reomte than when the camera has detected a face than the missle launcher can fire. Any thoughts?

you could always do the easy thing and get this

That thing is not autoaiming like this one (it could be tweaked the same way though). What you are linking to is the exact same missile launcher as the one in this instructable, except that it has a laser pointer.
