Arduino Buyers Guide And The Seeeduino

seeeduino

Make has assembled a buyers guide for the many different types of Arduino devices. The Arduino is an open hardware platform designed to make prototyping easily accessible. The design allows for other people to modify, expand, and improve on the base, and many people have started producing their own versions. The guide features a lot of the hardware we’ve covered in the past like the LilyPad, Arduino Pro, Sanguino, Duemilanove, Ethernet Shield, and Freeduino.

Out of the pack, the Seeeduino (pictured above) definitely caught our eye. It’s a low profile SMD design much like the Arduino Pro. They’ve taken advantage of the space saved by the SMD ATmega168 by adding more useful headers. In addition to the ICSP, you get the pins in UART order and an I2C header. Vcc is switch selectable for 3.3 or 5volts. The reset switch has been moved to the edge plus two additional ADC pins. Our favorite feature is the new spacing on the digital pins. Arduino digital pin headers have an inexplicable 160mil gap between the banks. The Seeeduino has the standard row for shield compatibility, but has an additional row spaced at standard 100mil spacing for use with protoboard. At $23.99, it’s competitively priced too.

USB Power From Your VGA Port

[gmgfarrand] needed an extra USB port to power some devices. Since he just needed power, and no data, he slapped together this quick adapter that pulls power from the vga port instead. While we’re not sure if this could possibly damage your video card if you pull too much power from it, we’re happy to see someone being original. That VGA port goes unused so often, this adapter might just make it a tad more useful.

TISCH, Multitouch Framework

November 23, 2008 by Eliot 7 Comments

[floe] wrote in to tell us about his multitouch based thesis work. While many projects have focused on the hardware side of multitouch, TISCH is designed to promote the software side. TISCH is a multiplatform library that features hardware abstraction and gesture recognition. This takes a lot of weight off of widget developers since they can specify known library gestures instead of writing the exact motions from scratch. Using TISCH also means a standard set of gestures across multiple widgets, so the learning curve will be much easier when a user tries out a new app. If you’re researching multitouch, check out this project and help improve the codebase.

UT Austin’s Massive Tile Display

The Texas Advanced Computing Center has built one of the largest tiled displays ever. They arranged 75 30inch Dell displays in a 5×15 pattern. The overall the system has 36GB of graphics memory and 108GB of system memory. They intend on using the system to display very large data sets. If you think the size seems arbitrary, it is. They just happened to purchase five more monitors than the University of California San Diego.

Stupidly Huge POV Display

[Mario Mauerer] and friends were commissioned to build this 2m persistence of vision display (translated) for a party (in a hight-voltage lab no less). Dubbed “Display from Hell”, it uses 100 blue SMD LEDs to generate the POV images. They’re connected to an ATMega64 via shift registers. Their target speed is 600rpm for a flicker free image, which means the propeller tips are moving at 140mph. The board can be updated wirelessly via IRDA and plans for adding SD storage are in place. You have to see and HEAR this thing in the video embedded below. Continue reading “Stupidly Huge POV Display” →

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” →

Animated LED Keyboard

[Brian] made this really cool LED keyboard. He started with a Deck Legend Fire. When he got it, he realized that every key had its own LED, but the entire unit was either on, or off. He just couldn’t live with that and decided to start hacking into it to make each light individually controlled. He found a perfect empty space in the back of the keyboard and designed custom PCBs to control his lighting. he notes that he spent 12 hours of cutting and soldering wires to each of the lights in the keyboard, that doesn’t include the PCB construction.

In the end, he had a fantastic looking keyboard that had cool effects like heat mapping and idle animations. All stock features still work and it looks almost entirely stock. The only obvious difference is the fact that it has two USB cables coming out of it due to some issues with his KVM switch not detecting it.
