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!
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.
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…
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.
I haven’t used the picoswitch, but have two cannons on my rover, the mounting is only half done but I’ve been so busy with a new job haven’t been able to update to a project page. They’re a one shot deal, but some work with a straw, hot glue and a funnel and you’ve got yourself a hopper that works nicely. then in a small area you can hold 1k shots and more. I’m using a simple npn darlington to run mine, works beautifully though my code is broken For some reason though the code starts with pins high instead of low, so aim away from your ankles when turning it on! I promise to work on it this weekend and get some form of update going, All I need to finish the project is a bigger servo horn to mount the structure on! Two cannons draw about an amp and a half when firing, enough to brown out your bot board if you use regulated 5v btw and reset the micro, so use battery power. No offense fish, but something about this example makes it seem more complicated than it really is to run them, especially the code, it’s really quite easy! But then again yours is working properly and mine misfires…
I use external regulators for just about everything. The micros regulator is kept separate from the header pin regulators on my board.
But i’m not using a botboard 2 anymore, i use this blog.basicmicro.com/blog/2010/10 … ardmini28/
I’m actually going to keep an eye on those npn darlington transistors.
Those sound awesome for a lot of projects.
Especially if they can handle that kind of power. Like an alternative to using transistor triggered relays.
Maybe if you set low on the pins, the first thing the bot does, like the very top of the code, it’ll go low, before it could even fire.
low p4
pause 10
low p4
A double low, at the very top. Just incase.
As for a hopper, i was thinking of using a straw too, 10 shots should be reasonable. And the gentlemen here at lynxmotion know i’m no stranger to hot glue. If only they could invent hotglue that didn’t leave those damn “webbies” everywhere. Damn hotglue webs.
