“down range”?
Most targets _are_ changed “down range”,
changing a target from “up range” (where the
shooter is) is a nice convenience.

(insert here Mel Gibson singing

as targer moves up range in Lethal Weapon (I) )

K’nex? Those look like the old Construx to me.

An even cooler use would be detecting when the target was hit, flipping it around and starting up the next sequence.

Good hack though.

Posted at 7:54 am on Jan 22nd, 2009 by Alexander

yep, definitely Construx.

Posted at 7:57 am on Jan 22nd, 2009 by Jeremy

These are construx not k’nex.

Posted at 7:57 am on Jan 22nd, 2009 by matt

Yup, definitely construx. I’ve been on instructables too much.

Should add some kind of sensor to each one to count hits and keep score.

Posted at 9:01 am on Jan 22nd, 2009 by numen

yeah, a hit/miss counter would be great.
then you make the code increase the rate according to your accuracy. So 100% hit rate would keep you on some expert curve but a lower rate would lower the challenge curve.
Also the targets need to be farther apart!

or just make it into a drinking game and skip the code.

Or have two paper targets on each target. It spins one way for a ‘bad guy’ target, the other and you get a ‘good guy’..try to not hit the good guys. A hit detector shouldn’t be too hard, but a miss detector wouldn’t be quite so easy. Maybe use a PC and a microphone to detect the sound of the shot? A shot sound + hit = score++, sound + no hit for x period of time = miss++

Put the targets between a light source and a webcam. The code to detect the light coming through the holes should be easy in ‘Processing’.

I’m just amazed there are still Construx out there. Miss those things from when I was a kid.

No Safety Glasses!! You’ll shoot your eye out!

Caleb is trying to get me all riled up about twitter. :) heheh, I see right through you, buddy.

good job on the target system. looks like a ton of work….a mini-engineering project.

my complaint is with the iobridge stuff…not open source; requires iobridge servers to work; etc. Of course there isn’t much of an alternative without some serious programming (unless you want to have a computer hooked up via rs 485/serial)

Posted at 4:38 pm on Jan 22nd, 2009 by fractalrock

a piezo on each target plus piezo on cardboard backdrop would detect hits and misses (hits would register both sensors). Twitter it to a scoreboard
‘downrange’ Dead simple.

Posted at 4:49 pm on Jan 22nd, 2009 by frollard

Yeah, they are indeed Construx. I had some ideas on “hit detection” but after all I can see the holes in the target face for scoring. Still, its really good feedback and ideas. I really like the one with the speaker detection and also the good/bad guy one.

Posted at 6:27 pm on Jan 22nd, 2009 by polymythic

yeah, you’ve got it. Construx.

Posted at 6:27 pm on Jan 22nd, 2009 by polymythic

Yeah, I had some ideas for this. I can at *least* check the target face before its torn to shreds (in full-auto on the pistol, it goes swiss-cheese in a hurry). Thanks!

Posted at 6:28 pm on Jan 22nd, 2009 by polymythic

I’d use a couple of servo’s and a PCI servo controller. But Im a big noob in this kind of engineering.

Posted at 7:05 pm on Jan 22nd, 2009 by deacon

tat doesnt seem so healthy for the wall behind the targets! actually .. why didnt you made the BB stopper stationary and just flip the target? that would make it possible to flip them faster too since you have lesser mass :-)
cool project neverless :-)

Posted at 6:41 am on Jan 23rd, 2009 by bullzebub

While you are at it, why not add a sensor that would be able to sense the location of impact, for airsoft training.

Posted at 9:02 am on Jan 23rd, 2009 by The Mainline

That’s awesome. Looks like a fun project. I agree with what people are saying about having a score counter though.

Posted at 10:47 am on Jan 23rd, 2009 by dgarman

The cut up shirt for the trap worked pretty well in fact. Nothing go through (unless I missed and did hit the wall, of course). The mass of the target face is very light, and very neutral, so I not even up against the torque limitations of those little servos yet. The code is posted on my site, so dropping some of the delays would speed the targets up even more. Good idea though, and thanks for the feedback.

Looks like something that the blackwater group sells for lots n lots of $$$ for big guns.

Posted at 10:40 pm on Feb 6th, 2009 by eric

You can make it out of K’nex too though.

want to download free music from http://www.us.dada.net can you provide me the method to do so. they give 3 credits but i need more.

Thats pretty cool that you can get the targets to move freely. I downloaded some Olly Lang tutorials from one of his paintballing websites on improving his accuracy and they are all pretty boring if you don’t have another player to peform them with.. Hours of fun to be had with that system..

Yeh it would hone your skills big time!
