How-to: Networked graffiti wall

Wondering what we did with our web server on a business card project from last week? It’s powering a giant LED graffiti wall. Animations can be user-submitted using the online designer. You can watch a live feed of user animations as well. The online interface runs on the Google App Engine for maximum scalability and resilience.

In today’s How-to we cover all the ins and outs of building your own networked graffiti wall. [Read more...]

Amazingly cheap dual channel scope

[Jacques] sent us this little project he has been working on. It is an amazingly cheap USB 2 chanel scope. The total cost of the project was around 5 Euros.  It is based off of an Atmel Tiny45, has 2 analog inputs, and can supply 5 Volts to a breadboard. He has listed the bill of materials as well as downloads for the source code, plans, and display software.

Helix V2.0 released

Helix 2.0 has been released.  Helix is a collection of various tools for electronic forensics.  Just like on TV, you can use this to find all kinds of information on a computer.  Some of the useful tools added were Winlockpwn a tool for breaking windows security, Volitility which processes data out of the raw memory, and several other tools that are beyond our comprehension.

You’ve undoubtedly noticed that the title says Helix V2.0, but the image and header of the Helix site say 3.  We have no idea why. Look at the download info to see that it says V2.0.

System admin steals 20,000 items from work

Over the course of 10 years, [Victor Papagno] stole 19,709 pieces of equipment from the Naval Research Laboratory. He began taking stuff home in 1997 and had so much that he had to store some in a neighbors house. The report says that no secret technological information was taken.  Some items listed were CDs, hard drives, floppy disks, adding up to an estimated value of 1.6 million dollars. He could face up to two years in prison for this. We shudder to think of the total cost of all the post its, CDs, and floppy disks we’ve taken home over the years.
