Graphics: I think I have too many projects...

I have a lot of hobbies. Sometimes I think I have too many. For a while now I've attempted to stay on topic with my blog so I don't give readers whiplash, but today I decided to change that. I'm going to try to start blogging about all of my random hobbies and projects as they are born, die, or are just forgotten about for a while.

Today my hobby is Graphics. I realize that is a large umbrella to be lumping things into, but I think the category will work for now. The truth is that I can't be more specific because I don't actually know what I want to do.

Coming from a computer science background most of my hobbies, and even my day job, drifts toward coding and technology. In the last few years I've written smart phone apps, web apps, linux admin scripts, firmware for micro-controllers, hostware to talk to the firmware, 3d objects for printing on my 3d printer, and the list goes on. One thing I haven't done since college is write 3d graphics / rendering applications. I feel like it's a muscle I need to stretch. I don't know what I want to do with the added muscle yet, but I've felt this way for a while. That's it... time to start a new hobby.

As a fun way of getting started I've decided to make a simple 3d game, but what technology stack / tool set should I use? At the moment all I have are requirements. Everything must be opensource because I believe in opensource. The rendering engine must be written in C++ because I want it to be as fast as possible, but not be a dead end.

With these requirements I am currently digging into Blender for artwork and OGRE for the rendering engine. God help me. Blender is the least intuitive application I have ever used! If anyone has some good tutorials, send them my way! OGRE, on the other hand, is a gem.

Finally, when starting a new project I find I need a constant source of motivation and inspiration. I just found it in a project called Overgrowth



These guys are good! I have to preorder to support their brilliance!

Update: Allan Ecker was kind enough to send me some cool blender links. I'm sharing so the world can benefit:
"Here are links for Blender: http://blog.thingiverse.com/2010/12/06/blender-2-5-interface-the-3d-view/ This is the basic, stop-pulling-your-hair-out tutorial that explains how not to be totally dumbfounded by the 3D view, which makes sense once you get the hang of it, but is totally baffling otherwise. Blendercookie.com has a long list of very good video tutorials which go from some excellent basic tutorials straight up to some pretty esoteric stuff, but blenderguru.com is where you want to go for photo-realism. Once you're ready for that kind of thing."

Thanks Allan!

tv: Dogbot Learns to Feel, Part 2

Season 2 : Ep. 5 | 12:32



This episode is the fifth in a series of episodes on creating a dog robot. This episode looks at a primitive pressure sensor design that I printed on my 3d printer. Is it enough to help DogBot feel its environment?

AllSeeing: back to the beginning...

In 2008 I found the RepRap project by searching for prototyping services. I was attempting to build a custom webcam mount just for the fun of it. Since then I have been deep into the RepRap movement and have started to make occasional videos about my research. Over my Christmas vacation I decided to take a step back and apply all that I have learned and all the tools that I have acquired and start designing and building a camcorder mount. Here is a shaky video of where I'm at right now with the mount. I had to film my camcorder, so I had to use my phone to take the video. :)



It still needs a lot of work but I hope you will agree it has already come a long way. So that's the first set of information that I wanted to share in this blog post. Stay with me while I switch gears. I found the following video last night. I smiled to see how much progress has been made by start-up companies in the area of robotics.



Now let's put these two things together. I'm just an average tech geek who built a 3d printer and likes to play with robotics. There are tons of people like me. The moment the people like me make the realization that [building printers] and [using those printers to build robots that pick up your dishes and put them in the sink] share comparable complexity is the moment the robot will become just another tool in the tech geeks tool box.

"Whacha doin' this weekend?"
"Oh, I'm just designing an upgrade for my drink bot. It dropped a glass last week and I have a feeling I need to increase the range of motion of its thumb."

On a final note, Forrest over at Technocratic Anarchist was working on a robotic hand last year. Cool.
