Klipsch Speaker Mods

P1010021 (Custom)

[Patrick] has a pair of Klipsch speakers that continually needed the volume knob cleaned. After a bit of research, he found it was a common problem with the potentiometer chosen for the task. He decided to resolve the problem, not by replacing that potentiometer, but by modifying the speakers to be passive and running them from an external amp. While this does sound simple at first, he wanted to retain the rest of the electronics in the unit, so a bit of hacking was required. You can follow along through the whole process on his site.

Second Hard Drive In A Macbook Pro

Picture 4 (Custom)

[Reid] wrote in to show us how to add a second hard drive to his Macbook Pro. He found that he hardly ever used his DVD drive, so sacrificed it in favor of added storage. What he found was that it had a proprietary adapter that he was unable to find for sale anywhere. Making an adapter may seem like a pretty simple hack, but this could save some people considerable time. Its also worth noting that upgrading the firmware got him an 18% speed increase, so don’t ignore those updates. We don’t see too many mac hacks around here, you may recall the mac tablet hacks and the logo monitor.

Handbot, The Shelf Climbing Bot

[youtube=http://www.youtube.com/watch?v=92bLgE6DO2g]

Handbot is one piece of a larger project called Swarmanoid. The aim of the swarmanoid is to replicate the functions we usually desire out of a humanoid bot with a whole swarm of specialized bots. That seems like a silly goal to us, considering the only requirement for a humanoid bot is that it be shaped like a human. That aside, we like their stuff. The handbot specifically is designed to retrieve books from bookshelves. It has specialized arms for climbing and grabbing the books with a batman-esque retractable rope launcher mounted on top for added speed and strength. The gait of the handbot really reminds us of how chameleons walk. We’re curious if this is a coincidence or not.

Hacking At Random

504x_camplikeapirate

The 20th Hacking At Random has recently come to a finish. For the unititiated, Hacking At Random or HAR is a massive hacker festival that happens every four years in the Netherlands. Four days of technology obsessed hacking with roughly 2500 people definitely piques our interest. The event is riddled with classes and people speaking on subjects such as censorship and robotics. Quickly built networks sprawl across the entire area, with shacks set up for location of servers. We think there should be an official Hack A Day tent there next time. We mentioned HAR when we were talking about impromptu DECT networks and DECT phone modification. Be sure to browse through the multitudes of pictures located on the HAR website.

Modular Computing

This is the Illuminato X Machina, a “cellular” style computing system.  Each unit is a fully functioning computer with its own processor, storage and communications.  You can watch above as a change in the operating software is propagated across the grid. You can see the LEDs in the video going nuts, there are actually LEDs on the sides too. [Justin] described it to us as a personal fireworks show on your desk.  This system is fully open with the schematics and source code available on their site. You might recognize these guys too, we covered their Open Source GameBoy.

Condom Testing Robot

coital-model

Broken condoms are a serious concern, not only for those who break them, but the companies who manufacture them. When studying the common reasons for breakage, a coital robot was used to simulate usage. Though it isn’t much of a robot, consisting mainly of simple pneumatics, it does serve its purpose. The study was able to determine the most common cause of breakage, and hopefully this information will lead to less occurrences. Robots do exist in the sex industry, and not just in that speculative future sex bot sense. Why weren’t any bots of a sexual background included in the big picture? The comments might want to stray towards future tech and possibilities, but we’re curious what there is out there currently and how robots are helping the industry.

Quick And Dirty Magnetic Card Reader

card

[nevdull] found himself in possession of a magnetic card reader. What else was he to do but show us all how to read from it using an AVR? He goes through the basics of how the card reader works, as well as how to detect the different card states such as entering, reading, leaving. There is source code to download to try for yourself, but unless you have the same reader, you’ll have to do some modifications. While this doesn’t get you all the way to reading the complete content off of the card, its a great start. Maybe you guys can help him finish up the last bits.
