This spoof infomercial had me in stitches. It’s actually a viral created by the team at www.superdeluxe.com and sadly, Dale’s three part ‘Master Of The Internet’ box set is not actually available. Something about that bad VHS quality makes it seem so authentic!
Not exactly discreet, but almost certainly a world’s first. David L Jones from Sydney has grafted a Homebuilt Scientific Calculator onto a watch strap.
It uses SMD components and a 16-bit PIC24fj64GA004 processor from Microchip. Looks like it’s a fiddly project to solder, but the end result is well worth the struggle. All the data is displayed on a backlit 16 character 2 line Dot Matrix display.
You can run it from one or two Lithium Ion Button Cells and manages to achieve 100 hours of calculator use and over a year of operation in sleep mode. It even has provisions for serial and Infrared communication!
David is planning on selling a kit version of the uWatch but has also released everything as open source with circuit diagrams and parts lists available from his site at www.calcwatch.com
Ever wanted to display graphics or an icon on a non-graphical LCD? This article covers the creation and display of Custom Graphics on a HD44780 Compatible LCD Screens. In this case, Mojo the monkey from the TV show the Simpsons.
Essentially, you are converting a raster image into a custom font letter which the LCD can then display. Great for adding a bit of personality to your projects!

Sean Chaney has been working on several laser projects. The one shown in the video above is a DIY 3D Laser Scanner…
‘The green laser bounces off a mirror then through a green beam splitter, the beam is then separated. The Green beam then bounces off a red diachronic filter and into the Scanners. The red laser passes through the red diachronic filter this allows you to mix the two colors into one beam or into dual images if the alignment is off’
In combination with software provided by LaserIllusions he has been able to create some impressive visuals. Go and check out Seans site at this link for lots more pictures and information.
Just noticed a link on hackaday to a story regarding a Denial Of Service attack on the Revision3 bittorrent tracker. They distribute their own media files which they own the copyright to using the bittorrent system.
After a bit of investigation, the team at Revision3 managed to track down the source of the DOS attack, and here’s the twist, it came from a legitimate company based in the US called Mediadefender which is in turn owned by Artistsdirect.
Turns out this company has been targeting the revision3 servers for some months now, injecting unauthorised torrents into their server. Revision3 noticed this happening and plugged the hole, this caused the Mediadefender servers to attempt to access the server over 8000 times a second. In an extract from Revision3’s own report on the incident, they state….
‘Grodsky admits that his computers sent those SYN packets to Revision3, but claims that their servers were each only trying to contact us every three hours. Our own logs show upwards of 8,000 packets a second.’
This all begs the question, what were they doing accessing Revision3 servers in this manner in the first place?
If you compare their extremely low-key website with their extremely high-key clients (Universal, 20th Century Fox to name but a few) it certainly seems like mediadefender want their activities to fall under the radar. As Revision 3 point out……
‘Denial of service attacks are illegal in the US under 12 different statutes, including the Economic Espionage Act and the Computer Fraud and Abuse Act’
Certainly seems like someone’s got some answering to do, you owe it to yourself to visit the Mediadefender wiki to see just what this company is up to
Ben Lewry has found an innovative use for his old laptop, stuff it inside an electric guitar! Not only does it still function perfectly, the laptop displays visualizations that move in time to the music.
Don’t know how distracting it would be trying to play it though, those trippy visuals would make my heads spin.
Go check out his youtube account for loads more videos of the unit in action, or yu culd always hed on overto Ben’s site at www.tvguitar.com - It only has a link to his myspace page currently, but its worth keeping an eye on for future developments.
We’ve all seen the will it blend videos that helped create a massively successful viral marketing campaign. Well take a look at this video showing you that even the worlds most powerful blender can struggle sometimes
It turns out that the worlds biggest GPS drawing that everybody has been linking to is actually a viral campaign created by DHL. Their excuse is that student Erik Nordenenkar asked them to use their warehouse for some photos for a project.
Looks like DHL have been caught out, still, they’ve managed to increase exposure and get a massive amount of free advertising…… so it’s not all bad

Straight from the archives, a Google TechTalks presentation from 2006 by Mike Andrews who is a senior technical consultant at a company that does network security testing. The whole thing lasts over an hour an a half so its a bit of an epic one but the information provided is excellent. Although slightly dated, im betting the majority of expolits shown and demonstrated are still out there.
See Mike spoofing ID’s and defacing websites live before your eyes.
‘The World Wide Web is a lot of things - a soapbox for everyone, a giant shopping mall, an application platform, and unfortunately a hacker’s playground. As more applications get "web-ified" moving from the desktop or legacy systems onto the web, attackers follow the vulnerabilities. Without sophisticated tools or "1337 5×1llz", web applications are now the most attacked technology, with the majority of attacks categorized as "easily exploitable". So, before your application is placed out into one of the most hostile environments, how do you stop your software from being "0wn3d" by the 14 year old in their blacked-out bedroom, or being used by a Russian crime cartel? In this TechTalk, Mike Andrews will look at how web applications are attacked, walk through a testing framework for evaluating the security of an application and take some deep-dives into a few interesting and common vulnerabilities and how they can be exploited’
We have featured LED projectors on hack247 before, back then they were still in their infancy, with few modders willing to try them out as a light source. But now with the release of brighter and cheaper LED’s onto the market, people are experimenting and coming up with some stunning results.
This particular project was pulled from the forums at http://diy2005.aa.topzj.com The projector uses an 8.9" lcd and a matching 8.9" LED light panel. The results speak for themselves, the picture looks bright and clear with maybe just a couple of issues on the corners. The benefits of using an LED light source over a traditional Metal Halide source are numerous, less heat, less electricity, longer life and a cheaper price mean that DIY LED solutions are going to be the way forward.
As the site is in Chinese we are struggling to pull any more details from the post, but pictures in this case, definitely speak louder than words.
Check out the forum post for loads more pictures and shots inside the projector at http://diy2005.aa.topzj.com/thread-388160-1-1.html or click on this link for a Google translated version which makes a bit more sense
