Dot matrix business card is basically done so next project... automated airsoft turret.
Currently I have modifed a cheap AEG to be triggered by a relay, and the relay is triggered by the microcontroller.
(http://img4.imageshack.us/img4/6910/turret1004lb5.jpg)
AEG was modifed by opening it up, removing unnecessary components, and using gardening shears to cut off excess plastic. A dremel took care of touching it up to look cleaner. The motor is hooked up directly to the relay.

Simple relay board, I decided to make it on protoboard just in case I fried the relay (first time working with them). Some connectors and one diode was all that was needed.

For asthetics, I would be making a laser "eye" like in the portal turrets. A hole is drilled in the center to accomodate a laser. I masked off parts around it that will light up red/green.

next you could mount it on servos
then you could use the stampy robot code moded so that it will follow the target
-
you need a MOSFET or transistor to drive the relay
-
Wow! That is So wickedly Awesome!!!
I am definelty gonna try and build one!!..or two...or three..(or one base with three turrets).........

After painting and removing masking

Painted gun white (what is with the clearsoft guns)
(http://img27.imageshack.us/img27/5397/turret2008rs1.jpg)
Fill inside with cotton to diffuse light, wrap inside with electrical tape to prevent light from coming out the sides
(http://img27.imageshack.us/img27/5451/turret2009ox5.jpg)
Insert laser and leds

nice. looks like that eye thing in big brother. where will it be used
-
Very nice. Which airsoft gun did you start with? I'm assuming you got one that is battery powered so you can activate the trigger with a pulse from the MCU?
I have thought of doing this as well, but can not find a cheap enough airsoft pistol around here that is battery powered that I wouldn't mind hacking up.
-
Yeah, it's one of those cheap no-name brand electric airsoft guns. I got mine in a two pack with a pistol for $30 at wal-mart a while back.
-
Getting a basic mockup of the tilt mount done, final one might be acrylic. It will be mounted on a rotating base (for pan). I used brackets from budgetrobotics.

Dude I've always wanted to do something like this!!
-
Cool!

I ran out of shampoo and got a great idea at the same time ;)

Razor Concepts used the " Pulse-M70 " fully automatic electronic airsoft gun...(i think...its made by a company called Crosman)
-
you need a MOSFET or transistor to drive the relay
trash the relay and just use a MOSFET alone . . . relays are useless today except for high powered stuff. 8)
Where did you buy the airsoft gun at? ERP could sure use a Predator style shoulder mount cannon . . .
-
Where did you buy the airsoft gun at?
just look online for the electric airsoft guns, they're everywhere!
-
I got mine at wal-mart or target. Dont spend over $30 for one or else its not worth it.
-
Added transistor to drive relay as airman suggested:

Finally got some PVC sheet to replace the wood.

wow, that looks great! but what does the bottle do? mag? air tank??
-
The bottle is used as a hopper, or a mag if u prefer....dont know why such a big one would be needed though...that thing could hold probably 2000+ BB's easily.
-
Razor, what's your experience with the reliability of the gun? I've been working on a couple of RC vehicles that originally had airsoft turrets, but the guns got jammed so often, I abandoned them and have switched to IR laser-tag guns. The airsoft guns I used were the cheap ones used in Heng Long tanks. They jammed all the time, and had awful range. I also tried a $20 gun from Walmart, which was also pretty worthless. It had a better range, but jammed a lot also.
-
The original unmodifed gun could only hold 84 BBs. Not enough for me ;D
I've used the gun unmodified for a long time, it has never jammed, although the original BB feeding system would get stuck so you would have to shake the gun a bit to get the BBs to roll down into the chamber. I added the front-feeding system on this to get rid of that problem.
-
if you use cheap BBs then they are not always perfectly round, so get wedged in the barrel. More expensive BBs are more round, so don't have this problem. This should even work with cheap BB guns.

Added a base and made a pitch control system using a servo and ball linkages.

-
wow, i like the way you made the gun pivot are you going to add another rotation axis?
-
I really feel like it needs more space to move... a bigger angle range.... really....
Except from that.... everything else just more than fine....
-
I also agree, it looks like it needs to move more, on the different axis as previously said.
-
I've used the gun unmodified for a long time, it has never jammed, although the original BB feeding system would get stuck so you would have to shake the gun a bit to get the BBs to roll down into the chamber. I added the front-feeding system on this to get rid of that problem.
Use a small vibrating motor, like a pager motor. Have it turn on this motor after every few shots . . . I see this done on feeder systems all the time.

awesome, Thats a great idea... :)
-
Changed location of ball link to get more pitch throw, and finally came up with an idea for pan. I used a budgetrobotics servo mount on it's side to hold the pan servo. Sorry for poor video quality, I misplaced my camera so I had to use my mp3 player

That is pretty cool. I want to see it shooting stuff lol.
-
Very nice project
-
now id love to make one of these that woudl be fully autonomous and shoot moving things (people) for my hexapod
-
Hmm

(http://i43.tinypic.com/jigd5j.jpg)
-
wow! that looks so good! great work razor!
-
hmmm... base looks a tad excessive... also, try cutting out a hole in the lid of the jar and set your servo inside the jar with the servo sticking out so that the base plate of the turret rests almost on top of the lid. It will look better and might perform better? Great stuff so far though!
-
Yeah, and the red eye thing kind of looks funny there. I think I'm going to switch over to a shorter base and put legs on it.
-
yea lol, that tower of a contained you have your turret mounted on makes the centre of gravity on it quite high, making it rather unstable...the last thing you want to happen is the turret go to follow someone and as i turns knock its self over :D
-
Very nice. Make a video of it shooting something when it is done, I want to see it in action.
-
This is much better. Going for a slightly offset look since completely symmetrical won't work well.
(http://i40.tinypic.com/2db2kvl.jpg)
(http://i41.tinypic.com/1zf38jq.jpg)
-
Much better :) Now all thats left to do is Scale it up about 250x, upgrade the main gun to fire at LEAST 6 inch shells, and add a vision targeting system :)
Looks good so far! keep it up
-
Hooooooo it starts to look like the turrets from Portal:

(http://th08.deviantart.com/fs11/300W/i/2006/244/6/e/Portal_Turret_by_mahalis.png)
Sweeet ;)
-
I want that game so friggen bad... must... not.... spend... money....
Just thought of something too. Is that going to be stable when it has the BB hopper on it? Perhaps giving it a wider stance will help make sure it stays balanced and such?
-
I'll be adding my own little "portal surprise" in a bit, just wait ;)
I ditched the huge and heavy BB hopper, will be switching to a much lower profile hopper that sits right around the gun. Base is still wobbly so I will be reinforcing it by connecting the bottoms of the legs.

"your business is appreciated."

:D
-
hahaha what the heck man :P I hope your going to make it have some cheesy phaser blaster sound every time it fires :P
-
Thats sweet, I want to go installs Portal again and play it.
-
Nice job. Keeps looking better and better.
-
make it mobile so you can compete in real mech-wars, link in this topic

some other Turret projects I found.

-
I still like this one the best. It has a nice design.
-
Stampy code is erratically working... my Sharp IR sensor still reads some funny values even though I grounded the case on two points and have 3 capacitors soldered right on it. Oh well, Stampy algorithim isn't exactly a perfect thing to begin with.
Mounted the eye thing, it will not tilt up and down because of space issues. If I actually put it on the gun it would look kind of bulky and out of place. The Roboduino and main battery are screwed on the underside, and I mounted the scanning servo on the front. The wave shield will go behind the pan servo, and the speaker will be mounted on the underside between the scanning servo and the roboduino.

To do:
Install relays to trigger gun
Reinforce legs
Add sound system
Add hopper
Add misc. LED lights to make it more interesting
-
I swear there's at least 30 feet of wire in there :P

(http://i41.tinypic.com/2aabosk.jpg)
-
Hmmm needs more cowbell :P
But in seriousness, have you considered perhaps enclosing the bottom completely so that the brains and speaker and such could be hidden? Might add to the appeal a little bit. Its looking really good so far though! Keep it up :)
-
Yup, need to pick up more plastic and will make some plastic walls around the bottom to cover most of the electronics up.
-
It tracks!

wow man! that things gonna be killer when its done!
-
Almost done :D

-
OMG lol that thing is awesome! hahaha nice work man, cant wait to see it when its fully done!
-
Woot Lord of the Rings in the video before last! ;D
-
Thats sweet, nice work with the LED's and tracking. I also love the portal sound effects. What did you use for the sound?
-
Wave shield from ladyada
-
RazorConcepts Auto Turret Testing (http://www.vimeo.com/4022830)
I need to adjust the tracking a bit. Next up are sensors to tell if the turret has been lifted off the ground, or if it has been knocked over. If one of those are tripped the turret will say more stuff ;) You know what I mean if you've played Portal.
-
I just 15 seconds ago purchased Portal on amazon for 9.99 plus shipping. And its all your fault :P
-
Too bad you could just buy it through Steam and download it instantly ;)
-
bah I dont have steam. Dont you have to subscribe to steam now-a-days anyway? Besides if my HDD ****s the bed again ill be glad I have a hard copy of the game :)
-
Done.
Wireless camera
Tip-over detection
Lifted-up detection

-
damn razor, fine work my man! is this the final product or are you adding more features?
-
Yup its done for now.
Also must keep in mind, metal note... get some more colors of wires instead of a few spools of black... gets very messy

-
Wow nice job Razor!
Here is a thought, do a Stampy algorithm with two Sharp IRs. One tracks left edge, one tracks right edge, and the gun just aims in between.
