Passively Cooled Computer

October 11, 2008 by Jason Rollette 38 Comments

This came in on the tipline: [Ville ‘Willek’ Kyrö] wanted to build a fully passively cooled computer. That means no fans at all. He started with scrap aluminum heatsinks, ripped apart a cpu heatsink to get the copper heat pipes, and began surrounding the boards with heatsinks to form a case. Cooling down the powersupply was the hardest part, as it did not lend itself to the flat surfaces of heatsinks. Any passive case with powerful components will inevitably be huge and heavy; this one weighs over 20 kg. He says, “It might not have been worth it, but it sure was weird watching the computer boot up with no sound at all”.

Drawdio Kit Lets You Make Music While You Draw

Drawdio, designed by [Jay Silver], is a fun, simple toy that uses the conductive nature of pencil graphite to generate different sounds. When you use the Drawdio pencil to draw or write, you also simultaneously create music. The entire kit is available for sale at Adafruit Industries, or for the more adventurous, separate components and parts are listed. The circuit is fairly simple and we wonder what other devices people can come up with based on this theme.

XKCD Inspires YouTube Feature

October 9, 2008 by Kimberly Lau 12 Comments

Who knew that a silly comic strip could be so influential? XKCD’s strip focusing on the inanity of YouTube comments inspired someone to actually add the Audio Preview feature to YouTube. It’s provided us with much amusement, especially where one commenter mentions that the “preview of my own post sounded moronic!”

Speech synthesis software is nothing new, of course. While it’s not the most sophisticated software, it’s an invaluable resource to those with disabilities, language learners, and others. This tutorial on Festival, a Linux-based text-to-speech software framework, would be a great place to start. You’re just moments away from finding out how stupid email, IM, and IRC sound read aloud.

ATM Skimmers With SMS

October 7, 2008 by Kimberly Lau 40 Comments

You may want to be more careful where you put that ATM card. There are now ATM skimmers with SMS notification. ATM skimmers are placed over real ATM slots and the information off the cards as they’re inserted. The new models will send the skimmed information via SMS notifications to a phone that’s attached to a computer. This solves the problem of scammers needing to retrieve their skimmers without attracting the attention of police. ATM skimmer manufacturers have so far been really successful because of their commitment to security, from the paint they use to cover their skimmers to their exclusive clientele. The manufacturer of this particular model claims that none of their clients who’ve used this new ATM skimmer has been arrested, and they only accept business from “recommended” clients. We think it’s interesting and ironic how these criminals have adapted their security procedures to deal with institutions we wish were more secure.

AVR ATtiny25 USB Hit Counter

October 5, 2008 by Jason Rollette 6 Comments

[Bob] has a USB page hit counter that uses an ATtiny25 to run a MAX7219 which drives eight 7-segment displays. It is easy to implement USB on an AVR using just firmware, eliminating the need for any USB to RS232 conversion. The host software is written in Delphi and sits in the Windows tray. The code examples seem simple enough to expand upon into your own display programs.

Sanguino ATmega644P Board

October 5, 2008 by Jason Rollette 23 Comments

The RepRap project, which is a printer that can make components using rapid prototyping technology, and it is designed so that it can eventually self replicate. Has released a new breakout board for the Sanguino that provides access to all the pins as screw terminals. The Sanguino is an Arduino compatible board based on the ATmega644P chip. You can populate the full board with all the components and have a fully functional single board. You could populate only the screw terminals and plug your Sanguino, and use it as a breakout board as well. The board design is released on Google Code.

Blinkenlights’ Stereoscope Goes Live In Toronto

October 4, 2008 by Eliot 7 Comments

We’re happy to present this guest post from History Hacker’s [Bre Pettis]. Today [Bre] catches up with the Blinkenlights team, who turn entire buildings into displays. Their current project is Stereoscope which goes live in Toronto, Canada today.

Earlier this week, I posted about the beginnings of the blinkenlights project. It started in 2001 in Berlin, but now Seven years later, in May 2008, blinkenlights is back. The City of Toronto asked the blinkenlights team if they would be interested in joining another Nuit Blanche (as they did in Paris in 2002). Short on time and with a lot of ambition, they decided to redesign and push the envelope on the project to make it wireless for The Toronto City Hall since there would be 960 windows split up in two towers. In the above photo, you can see Stereoscope in all its glory. Continue reading “Blinkenlights’ Stereoscope Goes Live In Toronto” →
