Spatialized Umbrella

umbrella-1

Reader [Joe Saavedra] sent in his latest project: the spatialized umbrella. The base of each umbrella rib features an LED, speaker, and distance sensor. These are connected to an ATMega168 microcontroller running the Arduino environment. The IR sensor triggers a rain drop sound based on proximity. Shorter distances mean more droplets are played. The sounds are generated using a lookup table and the digital pins. You can see the demo video embedded below.

Using the Arduino environment without the associated board is part of another idea that [Joe] is working on. The MapDuino Project uses the standard Arduino hardware for programming, but then transfers the chip to a more barebones circuit in target project. They based their initial work on the ITP breadboard Arduino. Continue reading “Spatialized Umbrella” →

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.

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.

Arduino + Wii Nunchuck + Servos

[Yezzer] has posted a video of a cool little project he’s working on. He has interfaced the Arduino and the Wii Nunchuck to control some servos. He mounted a standard USB webcam on it for good measure. There isn’t a whole lot of information, but he does include a few links to code he modified for the project. The movement is quite natural looking and seems like it would be a cheap way to get some good animatronic controls started. This might actually be a great way to control a robot for the Crabfu challenge, if they ever have another one.

Update: As [dokument] points out in the comments below, it looks like we’ve seen a set up that could be almost identical in the past.

Vexduino

[Jeremy] picked up a Vexplorer pretty cheap, and wanted to make it better. He decided that Arduino controls would probably be a nice upgrade. He patched into the controller and installed a nice looking plug to interface with the Arduino. He says the software was custom made as he couldn’t find suitable examples on the net. His software is available for download. We covered a picaxe controlled one in January, but it looks like that site is currently down.

The Narcisystem

biometric

The Narcisystem is part of an art display where [Eric] strapped himself to as many biometric sensors as he could. The core of the system was a Funnel IO which includes an Arduino, Xbee plug, and LiPo charging circuit. It was collecting data from a heart rate monitor, an EEG, a breathalyzer, compass, and an accelerometer. This data was sent to a laptop and then sent to different displays. You can see the setup functioning in a video after the break. The red flashes are his heart beat, the blue light is the direction he’s facing. What you can’t see is the high power bass thud every time he takes a step. The EEG data was supposed to effect the tempo of the music, but it failed and was dropped, as was the fog machine based on his blood alcohol level. He notes that he wanted to do more, but was lacking the hardware.
