Maker Faire Austin is happening this weekend, October 18 & 19, 2008 at the Travis County Expo Center in Austin, TX. Maker Faire is a showcase of all things DIY. You’ll see robots, sculptures, live performances, and other wonders including many of the projects we cover here every day. We enjoyed our time in San Mateo earlier this year and the show keeps getting better and better. You can see photos from previous events on Flickr. If you’ve got a chance to go, take it.

Spark Fun’s centerpiece at Maker Faire back in May was this LED coffee table. They just recently posted about how it was constructed. The surface is made from 64 8×8 RGB LED matrix boards totaling 4096 LEDs. The eight rows are connected to a custom router board so that one SPI line can control the entire display. The main microcontroller is an Olimex LPC2106 dev board. It runs a four player cooperative pong game where multiple balls are added over time. Each player gets a classic Atari paddle for control. You can see a video of the table running a screensaver after the break. Read the rest of this entry »

It looks like it’s time to update our event list. Here are some hacking related events happening through the rest of the year.

• ToorCon September 26-28 San Diego, CA – In its tenth year, ToorCon has always been one of our favorites. The conference is fairly small, but features great content like last year’s fuzzing talk.
• Arse Elektronika (NSFW) September 25-28 San Francisco, CA – Happening the same time as ToorCon, this conference covers the sexual side of human and machine interaction. The device list has gems like The Seismic Dildo, which only turns on if there is seismic activity in the world.
• Maker Faire October 18-19 Austin, TX – It’s Maker Faire! In Texas!
• Roboexotica December 4-7 Vienna, Austria – The premier festival for cocktail robotics is also back for the tenth time. They’re always looking for more exhibitors. Check out our Hackit for ideas.
• 25C3 December 27-30 Berlin, Germany I think we pretty much covered all the bases on this incredible conference yesterday.

Did we miss anything?

SWARM has been showing up at a number of places. Until now, the mysterious spheres have been under human control. However, the SWARM has taken the first steps to autonomous control. The SWARM is a kinetic art project consisting of several large self-propelled metallic spheres that interact with each other and their environment. Each orb in the swarm is fitted out with a processor, GPS, accelerometers, and Zigbee wireless communications. The entire project is open source. Slated to appear at the 2008 Burning Man festival, the orbs will use their GPS to wander within a specified area, keeping themselves “in bounds”.

As our final Maker Faire post, we thought we’d talk about some of the curious items that were handed us during the event.

While checking out Evil Mad Scientist Laboratories‘ latest generation CandyFab were given their AVR business card breakout board.

[Garrett] gave us a handful of ShiftBrites to play with in a future project.

We donated to the EFF, as we’re wont to do, and received a super bright blue flashlight for spotting the yellow tracking dots on color laser printouts. If you’re not familiar with this topic, you should check out bunnie’s blue light scanner.

Our final stop was at ifixit to pick up a free set of spatulas (spudgers?) for popping open iPods. All around a decent haul.

[John Peterson] showed us his Puzzlemation, animated tile puzzle at Maker Faire. It was originally designed for the Microchip 16-bit Embedded Control Design Contest. The puzzle is made from multiple modules each with an 8×8 LED grid. The tiles are battery powered and each one has PIC24FJ64GA004 microcontroller. They sit on a tray with flat copper strips as a serial bus. The tray controller broadcasts the animation to the tiles. Each tile waits for its unique identifier and saves that portion of the animation. The tiles don’t actually know what order they’re in so once the animation is in motion you can figure out their proper order; rearranging them so the animation is correct. We’ve got a video of it in action after the break.

Today’s episode of BoingBoing TV comes straight from Maker Faire. The first segement is about RoboGames arena combat. The second segment covers a favorite exhibit of mine. Western Warship Combat Club brought their 1/144th scale battleships to fight it out in a large pool. The RC boats fire ammunition up to 1/4-inch ball bearings and the even feature bilge pumps to keep them afloat. Scoring is based on where on the hull the strike happens. Here’s a direct link to the mp4.

We made a point to stop by [garrett]’s booth at Maker Faire to to see what he had been working on. You may remember him from his random caps locker shenanigans. He’s just recently released the ShiftBright RGB LED module which makes it easy to implement a string of individually addressable LEDs. The module is based on the Allegro A6281 3-Channel Constant Current LED Driver. The driver chip is capable of displaying a billion colors using an RGB LED. The 3×3mm package is mounted to the backside of the board while a bright common-anode RGB is mounted to the front. The modules are designed to be daisy chained together and are individually addressed using a serial interface. You can find Arduino example code on the site and more info on how the item was developed. Read on for close up images.

[Romado12187] just posted a walkthrough of his mechanical dry erase board project on Instructables. It was on display in the Microsoft booth last weekend at Maker Faire. Unlike [sprite_tm]’s version we covered earlier, this one is built more like a traditional pin plotter. The construction was done entirely in [Romado12187]’s dorm room and uses plywood and PVC pipes for the majority of the frame. The mechanical components were purchased from SDP/SI and the controller hardware are Phidgets. He included a joystick, but it also has a C# command line program for control. [Romado12187]’s write up also has a lot of improvements to help make your first attempt better than his; buying a premounted board and being very exact in calculating motor power are recommended. Catch a video of the plotter in action after the jump.

Builder [Justin Gray] brought a pair of electric motorcycles to Maker Faire last weekend. Pictured above is the R84, which has 28 LiFePo cells and an 84v AC induction drive providing 54HP. All of that is stuffed in a 2000 Yamaha R1 frame. You can buy it now for $14,000.
