Inspired by the Mech-Wars.. uh, Mechs, we've decided to add to the information pool by documenting how to fire one of these model tank airsoft cannons using an BBII/Atom Pro

The gun has a motor and a switch. You turn the motor on and monitor the status of the switch. As soon as the gun fires the switch goes low and the motor is turned off. Now off to attach it to a mech!

Here's a video of it in action.

Schematic:
Code:
             (+) 6vdc 
             | 
             | 
|--------|   | 
| pico   |---o 
| switch | 
|        |---o 
|--------|   | 
             | 
             | 
         red | 
         /-------\ 
         |       | 
         | motor | 
         |       | 
         \-------/ 
       black | 
             | 
             | 
           ----- 
            --- 
             - 
 
 
 (+) 5vdc 
  | 
  |      10k 
  o-----/\/\/\-----o-----> To I/O pin 
                   | 
                   | 
        switch     | 
                   | 
          /        | 
  o------o  o------o 
  | black    green 
  | 
  | 
----- 
 --- 
  -




Code:
Code:
 buttonA var byte
 
 gunSW var bit
 prevGun var bit
 x var word

 button_down con 0
 button_up con 1
 
 GunPin con p0

gunSW = in1
input p12


sound 9,[50\3500,30\3700,50\4000]

main

button p12, 0, 0, 0, buttonA, 1, A_Press

pulsout GunPin,2000

pause 20
goto main


A_Press
  sound 9,[50\3800]
goto fire


fire

pulsout GunPin,4000
pause 20

gunSW = in1

if (gunSW = 0) AND (prevGun = 1) then
 prevGun = 0
 goto main
endif

prevGun = gunSW

goto fire


Step 2:
Get some ammo :roll:

That was the first time I have seen one of those fired. I did not see any rounds fired so I assume it was dry fired? Great post!

Now if only they had a miniture airsoft gatling gun the same size as that tank gun, that would be great on a mech!


I found this video but it is way to big for a mech bot.

Both of them!

Great work James!

I've been looking at adding an airsoft cannon onto my rover, and was wondering where you found that cannon. I've seen a few electric airsoft pistols for a reasonable price, but am afraid that once I open them up, the firing mechanisms won't be a contained unit inside the case, and I'll have to fight with the motors etc and build a new case around them. This here looks like a simple unit you just wire up. Any thoughts/ suggestions on where to order? Are most of them pretty easy to modify from a gun into a mini cannon, or should I look for something off of a miniature tank?

Sorry for necroposting, anyone know where to find these still?
My boyfriend wants to put one ontop of my rover, he wants to start small before moving up.

Link doesn't work in opera or internet explorer.
It goes to http://toyeast.com/v3/ncatlvl1list.asp?cid=3

So i'm unable to buy from them at all, or even find it in the store.

I think this is the turret i'd need too, by the way, how large is the airsoft clip? it's not 1 shot and you're done is it?

That is so odd, that link I posted last night goes to the main toyseast website, oh well... What you can do is what I am doing, go to google.com, type in A02102961 and look for the link that has toyseast in it, the one that comes up for me is toyeast.com - vstank pro parts leopard2a5 airsoft barrel mechanism . I am not sure about the clip size though...

ok.. i think it's showing up ok now.

http://www.toyeast.com/v3/pdtdetail.asp ... =A02102960
http://www.toyeast.com/v3/pdtdetail.asp ... =A02102961
I don't know..

Toyeast's search is broken too, cant even search barrel mechanism..
Those two links work for me now, their site is really messed up.

They have more stuff here, i'm guessing the wiring is the same or very similar.
http://www.toyeast.com/v3/catproductlis ... 988&clvl=4

You think instead of a pico switch, a simple high/low relay switch will work?

Yeah I had a hec of a time trying to find anything on that site, and most of the time it's so slow that you can't even do a search...

I'm not sure about any of the wiring on those, I would assume it's similar...

On your switch it would depend on the rating of your switch and what one of those guns draw for power....

Oh the relay is 30V @ 5A.
Plenty of the motor on these turrets, no the concern is with the controls.

I assume it would be the same, except besides sending pulses, i would simply set high or set low.
I tested the relay, it works great. Nice and compact.
