Is anyone here familiar with them?

Go get 'em tiger.

I emailed the guy a while back asking how he made the 'BB minigun' thing that he used in this video

and he was quick to help. Even drew up drawings for me. I'm not going to make mine the same way though.

You sure are getting exited about this turret stuff. Now channel that enthusiasm and start building something. You can do it!

I don't know what you're so upset about Hmm let's see...
1. you're shamelessly advertising your own product
2. you pretend to be someone you're not
3. you say that step motors and servos suck, just because you'd have to spend more time to get them to work the way they should. However you state that ...

Now you're making it really obvious that you're trolling. I don't know what you're so upset about. You mad because it's not open source? You want everything handed to you for free? The world doesn't work that way.

You're right that those are your opinions. They will totally change though once you've actually tried some things yourself.

You must be trollin. Either that or you have a lot to learn.

Missing steps is not the main issue at all. See my previous posts.

One of the reasons it's no good (out of several) is because of the slight lag between real-time and the time that the PC has finished processing the frame that seems kind of counter intuitive - the software can detect motion and estimate lead but it cannot track a small dot?

Hmmm I found ...

..it would be a lot easier to mount an IR laser on the gun and use the camera to track it. nope. I've already played with that method.

I doubt any serious attempt to make a sentry gun with steppers would fail because of the use of steppers.

Near as I can tell, servos are almost always used in low power applications. For applications that require serious power from the motor(s), steppers seem to dominate. The reasons I mentioned ...

Like I said before, stupid in is stupid out regardless of the hardware.
There is a fundamental problem, and then several other smaller problems with steppers. I know what you're saying but I'll believe it when I see it. As common as it is for people to think steppers are the way to go I'm betting ...

I've seen it. It is just as bad as the others. I've seen them all and this one is clearly the most advanced by a wide margin. Forgive me sensei I forgot that you're not advertising your own product
You're making several assumptions to come to that conclusion. You know what they say about ...

That's why I suggested a microcontroler.... I've used code from the link I posted earlier in the thread and it works... you just send the absolute position through serial and the motor gets there... you might as well use ramp function that deals with inertia

You still don't get the fundamental ...

In the real world, particularly when precision is required, you don't tell the stepper to move X steps. You tell it to move 1 step and buffer the rest of the movement in software. If the target moves then you update the buffer. The software just looks to see if the buffer is non-zero then issues a ...
