New Term For Art: Sculptural Robotics

September 21, 2010 by Jakob Griffith 10 Comments

[Dan Roe] has been working on Sculptural Robotics for quite some time, and most recently presented his newest creation: Solar Flowers 2010. Typically, Sculptural Robotics (coined by [Dan] himself) are stand alone, static art presentations made from electronic components and wire. [Dan] of course has taken it quite a bit further; giving all his sculptures life using solar panels, motors, engine circuits, and more. Making them zero emission, and beautiful at the same time. You can catch four videos after the jump of his moving sculptures. Not that we’re picking favorites, but the dragonfly is pretty amazing if we do say so ourselves.

Homebrew Firmware Upgrade For VCI-100 Turntable Controller

September 20, 2010 by Mike Szczys 13 Comments

We love hacks that take quality products and make them better. This enhanced firmware for the VCI-100 is a great example of that. In a similar fashion as the Behringer hack, [DaveX] reverse engineer the firmware for the device and figured out a few ways to make it better. It improves the scratch controller and slider accuracy to use 9-bit accuracy from the ADC readings, which in the stock version were being shifted down to 7-bits. There’s also a few LED tricks they call Disco Mode. They’re selling a “chip” that you need to flash the firmware but from what we can see it’s simply an RS232 converter so you might be able to figure out how to work without that part. We’ve embedded a demo of firmware version 1.4 after the break.

Dead Motor? Think Again

September 16, 2010 by Jakob Griffith 28 Comments

While hobby brush motors are pretty cheap now adays, there’s always that feeling of why replace when you can rebuild and reuse. As such [John Carr] presents how to change the brush position in motors to revive a dead motor. So long as the motor dies from natural causes commutator wear, the idea is the brushes can be moved along the axes and fixed to a new portion of commutator that’s not worn at all. [John] also goes through the details of some tricky reassembly, but we think to make this complete a guide on brush replacement and commutator replacement might be in order hint hint.

Atari 2600 Recreated In An FPGA

September 15, 2010 by Mike Szczys 16 Comments

Behold [Retromaster’s] field programmable gate array implementation of an Atari 2600. The processor and video chip have both been built in the 100,000 gate Spartan-3E FPGA, with connectors for audio, video, and a Sega controller. The output signals are generated using two DACs made from R-2R resistor ladders, much like the project we saw in August. [Retromaster] included functionality for the system switches (difficulty and select) in the controller itself. There is VHDL code and board details available if you want to make one of your own. To help in making that decision we’ve embedded video of it after the break. Continue reading “Atari 2600 Recreated In An FPGA” →

Revive A DockStar And Get So Much More

September 9, 2010 by Jakob Griffith 10 Comments

[Firestorm_v1] has done a fabulous writeup on not only resurrecting his dead DockStar with JTAG, but also includes some handy techniques and useful information that could be used with other hardware and JTAG equipped devices.

The tutorial itself goes into the details of finding the JTAG, correctly identifying the ports and making an adapter cable. Then wiring a TIAO Parallel JTAG kit and finally the flash and upload of firmware to the deceased Dockstar to give it new life.

While the fun stops a little short, we’ll be sure to keep an eye out for [Firestorm_v1’s] future plans involving these surprisingly useful (read: hackable) storage devices, “roving USB camera with WiFi” we hear?

Firmware Hacking On Behringer Midi Devices

September 2, 2010 by Mike Szczys 8 Comments

A new project called the Unofficial Behringer Control Development Kit lets you tweak or completely replace the firmware on the popular devices. The proof of concept demo shows a custom message scrolling on the 4-character 7-segment display but you can do with the device is only limited by how well you can code for the ARM processor inside. Development takes place using the GNU ARM toolchain but don’t worry, you don’t have to crack the case open to program the chip. The BCR2000 and BCF2000 models supported by the project both run bootloaders that allow firmware updates via midi commands. There’s even a recovery mode if you screw something up. Just make sure you have a direct midi connection for recovery, the USB port won’t work for that purpose. If you need a shove to get you started there’s a nice little example file in the repository.

Barcode Infiltrator

September 2, 2010 by James Munns 25 Comments

Whenever someone manages to expose vulnerabilities in everyday devices, we love to root for them. [Adrian] over at Irongeek has been inspired to exploit barcodes as a means to attack a POS database. Based on an idea from a Pauldotcom episode, he set out to make a rapid attack device, using an LED to spoof the signals that would be received by scanning a barcode. By exposing the POS to a set of generic database attacks, including XSS, SQL Injection, and other errors easily solved by input sanitation, he has created the first version of an automated system penetration device. In this case the hardware is simple, but the concept is impressive.

With the hardware explained and the source code provided, as well as a basic un-sanitized input cheat sheet, the would-be barcode hackers have a great place to start if they feel compelled to provide a revision two.
