Stepper Motor Controller From Old Scanner

[Murray484] submitted his instructable on how to create a stepper motor controller from an old scanner. He removed the motor and controller from an old scanner then harvested the parts. He’s pretty much starting over, taking the ULN2003 chip from the scanner motor controller and putting it on a fresh board. He then wired it all up, installed the software and got it working. Finally, he built a container out of cardboard for it all. Though he could have made it nicer looking and used higher quality building materials, he was trying to make this a “green” project for the epilog laser cutter contest. He’s done a good job recycling, this could be pretty useful.

Portal-ish Automated Turret

turret

[RazorConcepts] has built this cool automated turret. It is a home made frame with an airsoft gun, a Roboduino development board, a rangefinder, camera, and some servos. They programmed it to keep up constant random banter from the game as well as respond appropriately do different inputs. For example, it complains when you pick it up or knock it over as well as announcing if it has acquired a target. The range finder is mounted on its own servo which constantly sweeps back and forth, so the turret itself mainly sits still. You can see that the tracking is not so great in the video. [RazorConcepts] notes in the instructable that this is because the main focus was just to make it for “show”. We’ve seen our fair share of turrets before. We think he did a good job, but if it is just for show, maybe spend some more time on a nice body and smoother motion.

Toddler Computer Remote

[Killerdark] has built a simple remote for his toddler to control videos on a PC. He gutted a USB number pad, built a new enclosure with the necessary buttons clearly labeled, and mapped the buttons in software. He could have possibly done better with larger color coded buttons, but really, it seems to work well as is. This reminds us of the giant iPod remote from back in 2006. Good job [Killerdark]

Arduino VGA Glitching

glitch

For some people, mistakes or glitches has become an art form. We’ve seen it in circuit bending for a while, but the newest version is in video glitching. [Sebastian] has gone so far as to intentionally set up an Arduino to send a glitched signal to a monitor. His description sounds pretty easy. We’re just assuming this is in motion in some way, a video of it in action would be nice.

Power Glove 20th Anniversary Edition

Using an original Power Glove, a bluetooth module, an Arduino, and an accelerometer, [Biphenyl] brought the system up to date. As you can see in the video after the break, the new version is wireless and much more useful in the games. Skip to 11 minutes in if you just want to see it in action. There’s a full writeup on Instructables if you want to build your own. We love the power glove and we can’t wait to see a more developed game for it. This beats the Power Glove Wiimote, hands down.

Lego Head Tracking

[Epoch] Sent in this simple head tracking project using Lego pieces. He’s made a custom mount to hold 3 Lego light sensors on a baseball cap. Then, after modifying his webcam for IR with some floppy disk scraps, he loads up the free-track software and can control his games. For convenience, he has programmed the Lego Nxt to only turn on the lights while he’s holding a contact sensor. You can see it in action after the break. This appears to be very similar to [Johnny Lee’s] head tracking. Judging by the video, it’s not as smooth though.

Capslocker 2

caps

Almost exactly a year ago, we posted the random USB capslocker. [Garrett] has revisited the idea to build a smaller, neater version. He has posted the build process to give us an idea how he goes about building things. The overall build is quite nice, but part if its neatness can be attributed to the fact that he had access to an Epilog laser cutter. If you think you might be using one in the near future, this is a great writeup for you.
