Cythbot, Pneumatic Guitar Hero

Here’s yet another robot hoping to dominate the human race through the power of ROCK. Cythbot was built to demonstrate Cyth Systems machine vision systems. The device uses a camera to watch the Guitar Hero monitor and identify notes for button presses. The strum bar is then triggered after a delay. The notes are identified solely by pixel intensity since star power can cause them to change shape and color. All button presses are done using pneumatics. The whole system is self-contained and doesn’t require a separate computer for processing. Our favorite part is that the controller remains completely unmodified and the industrial light tree used to indicate notes. The team says that the pneumatics aren’t quite fast enough to hit 100%, unlike some humans. Video of the bot in action after the break. Continue reading “Cythbot, Pneumatic Guitar Hero” →

Simple Servo Bot Plans

oomlout has posted some interesting plans for a simple robot. It’s based around an Arduino and is a platform similar to the Parallax Boe-Bot. The Arduino sends PWM signals to continuos rotation servos that drive the two main wheels. All of the structural components are laser cut from acrylic with slots to hold standard hex nuts. It’s an interesting technique, but the design has a lot of potential for improvement. Right now it uses two different power supplies and a breadboard for simple connections. From the video below, you can see that the balance could be improved as well. Continue reading “Simple Servo Bot Plans” →

There is no doubt that [Johnny Lee] is the authority on Wiimote based projects. So, when he compiles a list of his favorite Wiimote projects, we definitely pay attention. He’s organized the list as a progression of the unusual. By the time you get to ‘Chicken Head Tracking‘ at the bottom, you’ll be adequately prepared. You’re bound to get some inspiration from the list even it’s building a pigeon guided missile.

CNC Engraver Upgrades

We’ve been following [glaciawanderer]’s CNC build for quite some time and he’s recently added a few upgrades to make for an even more interesting machine. He’s been trying out new bearing blocks, anti-backlash nuts, and z-axis plates hoping to get some improvements. In the case of the bearing blocks, he went back to the older style because of the added safety and smoother movement. The final addition he made was a dust collection system. It’s just a couple support hoops and duct tape, but it should keep dust out of the threads and rails.

YouTube Testing Even Higher Quality Videos

YouTube, purveyor of some of worst looking flash video is finally getting their act together. We posted the other day about embedding videos using &fmt=18 to get higher quality YouTube videos. It seems the awesome knob has now been turned up to &fmt=22. All of the previous tricks should work, just use 22 instead of 18. This all depends on the highdef version being available. Now they just need to get rid of the grainy preview images.

Wii64: A Nintendo 64 Stuffed Into A Wii

File this one under “stuff that doesn’t make sense”. Someone put a Nintendo 64 into a Wii. Yes, we know you can download those games with virtual console. Maybe they did it just to look cool. Maybe a Wii case just happened to be laying there when they got some Nintendo 64 guts. Whatever the reason, it is for sale on Ebay.
