Eureqa Discovers Equations

December 4, 2009 by Gerrit Coetzee 35 Comments

While “Software to discover equations and mathematical relationships in data” isn’t at the top of our christmas wish list, we have to admit that Eureqa is pretty cool. Developed at Cornell University, Eureqa uses machine learning algorithms to determine the underlying math behind data sets. It derived Newton’s second law of motion in a few hours on a standard desktop computer, which isn’t bad at all for a cold unfeeling robot mind. There probably aren’t many applications for this in most hacks, but what hacker wouldn’t want Sir Issac Newton’s brain in their toolbox? The software can be downloaded for free from their website.

How To Use Wiimotes W/ Linux

November 28, 2009 by Jake W 20 Comments

[Sprite_tm] has whipped up yet another interesting tutorial – software-based this time. He basically describes how he connected his Wiimotes to an HTPC. A USB Bluetooth receiver, and a little bit of Linux scripting, was all that was necessary to get the system up and running. To add to the fun, [Sprite_tm] configured a the controllers to work with MAME (an arcade machine emulator), allowing one to play Duck Hunt on a computer in its full glory!

Software Auralization

Have you heard the latest track by gzip? Maybe it’ll end up on a “Greatest Hits” album alongside Philip Glass.

Visualization techniques such as animated algorithms can help programmers better grasp the abstract theories that make software work. Could auralization, the sound equivalent of visualization, provide similar insights? Postgrad student (and J. S. Bach fan) [Cessu] developed a program to do just that. By carefully mapping registers to notes, and slowing the tempo to a human timescale, the result is a cacophonous machine that offers a glimpse into the operation of various programs. You might find the resulting minimalist “music” insightful, entertaining…or maybe just incredibly grating.

Fritzing, Go From Prototype To Product

fritzing

Fritzing is an open source project designed to help you move from a prototype to a finished project. Aimed at those basing their projects around Arduino, you start by building your physical prototype, then recreate it with Fritzing software’s graphical editor. From there you can generate a schematic, PCB artwork, and PCB production files.

Rename Files En Masse In Windows

Bulk Rename Utility

Everybody hates it when they have to rename a fileset to fit a new naming scheme. Instead of doing it the hard way and writing a one-time script to go through and rename everything, check out Bulk Rename Utility from [Jim Willsher]. It provides you with a multitude of methods to take care of business and allows you do pick your favorite method, be it regular expressions, simple finding and replacing, prefix/suffix modification, or a combination of many more.

However, if the sheer amount of options available overwhelms you or if you just want an easier way to do things, check out A.F.5 from [Alex Fauland]. A.F.5 offers features like adding a counter to your filenames, change file attributes, and save your rename settings out to a file for repeat use.

Twittering Keylogger

July 1, 2009 by Zach Banks 16 Comments

[Kyle McDonald] sent in his latest project, a software keylogger that twitters what you type. He wrote it using C++ and OpenFrameworks. It logs each keystroke, then it posts to twitter 140 characters at a time. To protect himself, he set up a whitelist of private strings like passwords and credit card numbers that would be stripped before posting. If the twypewriter followed him, his keystrokes could be recreated.

[thanks Kyle]

Bus Pirate Firmware Update V0g

June 25, 2009 by Ian 10 Comments

buspiratefirmwarev0g

Firmware v0g for all Bus Pirate revisions is now available. Updates in this release include a bootloader, frequency generator/pulse-width modulator, SPI bus sniffer, MIDI library, configuration reports, improved user interface, and bug fixes. v0g is also the first firmware to fully support the v2 hardware branch.

We’re really proud of this release as it brings a much more consistent structure to the internal operation of the Bus Pirate. It lays the foundation for future CAN, LIN, and OBDII libraries, and it supports localization and translations. Install and upgrade instructions are included with the firmware. Report bugs on the project issue tracker.

We document the new features after the break.
