I started in on the Rockcliff plans yesterday. SCA training and fighting have halted it until next week, though. Also, I have just one major part to get: the ground ways and linear bearings.

Another Halo 3 weapon.

Sniper Rifle, fruit of ~2 days’ labor. Enjoy.

I’ve started a small side project for the Halo costuming community, basically it’s modeling in Solidworks several different weapons from Halo 3.

The first is the M6G Magnum, I’ve set aside a page for it so I can update the models in one place as I improve them.

I’ve managed to beat Solidworks’ loft tool into submission.
Now it produces this very nicely every time I ask.

Well, I figured out how to do more complex work in Solidworks, especially for vacuum-forming. This piece you see above could be turned into plastic

From here I think it’s on to the actual armor! I might try starting at the boots this time.

I haven’t been building robots for a while, and I need funds for this project, so here’s a bunch of robot parts for sale.
Most, if not all are almost like new, practically. Which is to say.. there’s no new-parts smell.

update: onwards to ebay. links:

Not much to it, really.

Basically, it’s a standard ATX-type power supply, with most of the crap cut off, and the power=good line soldered to ground.
That lets it run without being attached to a motherboard, and be used for lots of other stuff.

I googled info on how to go about doing this, here are the instructions.

I got the driver board assembled. I have yet to hook up motors to it, but here it is pre-burn-in.

Hopefully this’ll make a nice controller. I realized, though, that I need to find out how to get the signal for the dremel on/off to a relay or something. More research required. I guess I can figure out which permutation of machine I want to build and pick up some MDF and hardware tomorrow, too.

I got the main guts of the CNC machine in today- the stepper motors and driver board kit.

Fairly standard, as far as specialized electronics goes. The motors are ~300 oz-in, and the board can run 4 axes.
I’ve read through the docs, and it looks pretty simple- I should have it done and tested soon.

Well, I need to see if a passive external skeleton will work before I start casting aluminum. I’m not sure how I should mock this up, but the joints look like a good place to start.

Of the 14 main joints, 5 are straight hinges. Two have loose hinges or floating axes of articulation. Two utilize ball races or interlocking flanges to put the wearer through the joint, in conjunction with sliding hinges. Two are freely rotational with loads of axial play. The two hip joints are either ball joints or universal joints, and the torso rests more or less loosely atop the pelvic armor.
