Transferring keyframes from mocap armature to your rig

Once you have all of your constraints applied and your rig is moving as expected, you can apply those keyframes to your rig (so you can remove the mocap armature) by pressing space and choosing “bake action.” Be sure to choose “clear constraints” or your rig will have all the constraints applied twice (once from the bake, and once from the constraint that is still in place).

Having a character pick up an object in blender…

The object to be picked up needs a “Child of” constraint. The tricky part is that applying the constraint will cause the child object to “jump in space” relative to the parented object. To counter this, you need to select the child object (on the frame where the object is to be picked up) and click “set inverse”. You can then set keyframes on the “influence” slider to represent the amount of influence the parented object has.

I still have no idea how to put an object back down in a different place. The inverse process does not seem to work.

Two new projects added.

I’ve let this page languish recently. That’s the story of the Internet. But I recently posted two previously unseen projects, and a video of some wall-racing autonomous RC cars. Check the links on the right!

FEZ Domino. I’m a fanboy

What’s open source, runs the .NET framework, and allows you to utilize all the power of Visual Studio .NET for embedded systems development?

The FEZ (Freakin’ EZ) Domino and it’s sibling, the Mini.

Now, that last part was as hard for me to say as it was for you to hear (or is it see?). I’m not a Microsoft fanboy by any stretch of the imagination. In fact, I’ve earned my living for the last 5 years as a Linux system administrator — and I have no intention of ever returning to a Windows domain of my own volition. That said, there’s no denying the power of the .NET framework, C#, and the Visual Studio environment and their impact on rapid prototyping and development cycles.

Loyalties aside, the FEZ Domino is somewhat akin to an Arduino on the juice . In fact, the FEZ Domino even maintains pin compatibility with the Arduino so the drawer full of shields you’ve accumulated over the years won’t be going to waste. And, if your stepping up from a Parallax BASIC Stamp, then the FEZ Mini has you covered as a drop-in replacement for your old BS2 projects.

There’s nothing like a little competition, and that’s true in open source as much as in business. I don’t know when the FEZ Domino was released, but I’m glad elektor ran an article about the .NET Micro Framework in this month’s issue, or it may have continued to go relatively unnoticed in the hobbyist community.

And sure, you could argue about the merits of avr-gcc, or the flexibility of creating your own makefiles. But let’s be honest with ourselves for a minute. The Arduino (and clones), the BASIC Stamp, and the FEZ Domino aren’t really targeted at professional, manufacturing-grade engineers. They’re targeted at people like me an you. Yeah, you with the ThinkGeek t-shirt and Nerf gatling-gun hidden beneath your desk. People who like to explore technology, and to share their discoveries with the rest of the world. People who like to build, tinker, and Make, and to see their ideas come to life in the real world.

FEZ Domino just made it even easier to do just that.
