David Worden let us know that he has completed work on his Disco Bar which we covered earlier. To save his bandwidth, I suggest you watch the video on YouTube.

Email On The Cisco 7960
The Cisco Unified IP Phone 7960G is becoming fairly common in corporate environments. The phone has a built in XML browser for navigating menus. [Nick] decided to hack together a PHP application that will let the phone display email messages in a POP3 account. In its current form it works with most text-only messages, but limited filtering means it could fail on some.
How To Reverse Time
[moddy] sent in a couple of his projects that would probably be entertaining on a Sunday afternoon. The first one is how to reverse the rotation of a battery powered travel clock. It’s just a simple modification of the plate the coil is wrapped around. The second is adding 9V battery terminals to a cell phone. Neither project is practical, but they’re still fun.
$100 Hot Water Bottle Pendulum Rebreather
Humans exhale a lot of oxygen along with their waste carbon dioxide. Instead of throwing out this oxygen, a rebreather uses a scrubber to remove the CO2 and replace it with pure oxygen from a bottle. Tom Rose built this rebreather for $100. When you exhale air passes through the scrubbing material and is stored in hot water bottle counterlung until you inhale. The system is only 15 pounds; a great savings compared to most dive equipment. You are definitely putting your life in your own hands so this should not be used without plenty of “couch-diving” tests. Tom has a ton of other diving related projects on his site.

UV Box For PCB Exposure
Hack-A-Day reader [Mindaugasu] built this box for exposing copper boards to ultraviolet light before etching them. It has two banks of four 20W UV lamps. The box is lined with reflective foil. The banks can be controlled separately and the exposure time is set by an Atmel AT90. You can change the time using button panel and LCD. He’s got some example boards in his ARM development section.
Commercial-grade TIG Welder
I use the qualifier “commercial-grade” here because this TIG welder project goes far beyond our junkyard TIG welder. The welder has a 180 amp capacity and has most (if not all) of the features of a modern welder. Instead of using a microprocessor, Dave Barrett decided to use discrete TTL and CMOS logic. That decision should make the design a lot easier to troubleshoot. Schematics and board layouts are on his site.

SCrAmBlEd? HaCkZ!
This story as appeared many different places [via Music thing], but I wanted to make sure you guys didn’t miss out on the fun. sCrAmBlEd? HaCkZ! by Sven K? is an amazing piece of video remixing software. It’s built using C++, Python and PureData. It takes music videos, chops them up by beats and indexes the samples by sound signature in a database. You then beatbox into a microphone to describe the music you want to hear. The software builds the music you want out of the sample database. Sven has put together an excellent video that describes the program and has example performances. It’s a must watch. Get it either directly from his site or watch it on YouTube.
