Here is a progress vid of my skull mech. I'm trying to duplicate the tilt axis of the Skulltronix in a 4th class Bucky skull. The eyes and jaw mech are still in the works, but this video shows that I did accomplish 3 axis' in a bucky. I used a Parallax and VSA.[EDIT...correction: That was the Parallax software I used in the vid. ]

Wow! Roll, pitch and yaw in a Bucky! That rocks, Dr. M - makes my jawbone-only motion seem in need of an upgrade!

Thanks guys. The jaw is next...The eyes I have VERY special plans for. They will move up/down side/side and light up. Yes, a skulltronix skull IS what I'm trying to duplicate in a bucky, and I've only spent 90 bucks so far in parts, including the servos and Parallax board...Oh, and that's The Langoliers on TV in the background..in case you were wondering. Probably not though.

Man that's great Doc. I have to wait for next week to order the parallax board but I'm not giving up yet!! Working on this myself I know how much work that is. Quite impressive, never even thought to try the third axis, just the tilt and pan. Any still shots of the mechanics or are those top secret???

Morbius,

That is really sweet. I can't wait until my servos arrive so I can get started on mine as well. When you're ready, I'd love to see how you connected the PVC neck bracket you made to the skull. I know the Skultronix folks make their own skulls, but I did want to know what you think of these Bucky skulls being so heavy. Do you think it affects the servo performance at all??
Great job and I'm very excited to track your progress.

BTW...I know the Skultronix prop is very expensive, but you really have to give them credit for the wonderful engineering they've done. Not to mention we are all trying to emulate them. I equate their product to what the Disney World people have been doing for years, so I'd say that is about the greatest compliment anyone can give them.

Skulltronix is the Lamborghini of cars, no argument. Many of us just are trying to come up with enough moola to buy a Yugo! LOL

Dr. M,

Are you going to patent or sell the mech? Inquiring minds want to know and see pics !!!!!!

Z
Yes, and yes. I'll show everything when I get the patent application in. Believe me, even if you did see it, it's real hard to make. I used all aluminum brackets and steel bearings.
Doc, there's a lot of people who would buy from ya and save the $1000+ ...just a thought.
That's the idea, Sickie. I hope to come way under that price.

All the PVC bracket is, is just a steel threaded rod coming from the neck and placed inside the pipe then I used a set screw to hold it in tight.The bucky is heavy, but when balanced properly, the strain on the servos is minimal. I really do give Skulltronix credit, thier product IS fantastic. A bucky doesn't have the same facial character that the Skulltronix skull has, as the brow is anatomically correct in a bucky. However, I will be partnering up to offer skins akin to Bucky lids one could slip over the skull, so you could have a witch, zombie, gravedigger, greeter and the like. I wonder if that would be something folks would be intersted in?

Buy my Yugo! LOL! Seriously, I know there are TONS of folks unable to afford a Skulltronix, and will NEVER buy one as a result. Me included.That's why I'm doing this.

I have to look into adding another servo for the tilt without redesigning my current config, that turned out pretty good. I see you used the Y in your design too. From the looks of it on paper I would just have to split the Y so it pivots on the bottom of the 'v' instead of being one piece. This would enable the pivot to twist.

I did use the Y, but I modified it for size. Oh, yes, no doubt, your bracket inspired me..I'm sorry if I didn't give you credit for that. Other than that, the whole thing had to be redesigned to fit in the skull and allow for an eye mech. Let me know how it turns out. I'd like to see your take on it. If it is really easy to duplicate, I'll have to rethink selling it.

So Doc, if I were to obtain this, what program would I need to make it move? Would it hook up to my computer or be self contained?
