DIGG, DIGG, DIGG, It's a circular world we are living in and what better way to show it off than with a Digg button that shows the Digg count of the Digg story you Digg on a giant Digg button display in the Digg offices by the cousin of Digg (Revision3's Systm) at diggthediggbutton.com

David Randolph and guest host Leah Culver stress test and then tear apart the iPhone immediately upon exiting the Apple store on launch day.

So you've heard about the DIGG button and P.O.V. toys, and maybe even LCD drivers. What drives them? How do they work? Why should you care? On this episode of Systm, we tackle that very question as Patrick and Dave take a look at AVR microcontrollers. What should be simple becomes an overly complicated project that only a super NASA engineer would even think of handling if the world's fate was hanging in the balance and Bruce Willis was our only hope. So sit back and enjoy the ride as we make an LED blink on and off.

Calculating resistance and power isn't hard... and, as David explains, knowing Ohm's Law and the Power Triangle can be darn useful when you're designing a project, sorting out power supply issues, or want to keep from burning your car down.

It was Taser week on YouTube, which inspired David and Patrick to look at the tech behind electroshock weapons, from cattle prods to Tasers. It's a good reminder that Amps kill, not Volts. PS - be careful when you fry foil with a DIY camera taser.

In our biggest failure since the WiFi Episode, Systm trys to power an iPod with Lemons and create a Lithium Ion battery fire. Find out what exactly a battery is... and why we want a battery tech breakthrough in the worst way.

Diesels get better mileage than gas engines. Biodiesel has a lower carbon footprint and supports farmers. Great reasons to dump a gas engine and run biodiesel. Want a better reason? Exxon made 36 Billion last year... you don't have to buy gasoline.

If it's got a 386 processor and 32MB of RAM, and you can find a pair of Ethernet cards, you can turn that Junk PC into a serious Firewall to protect your network.

Got five minutes? You can make any USB Thumbdrive waterproof with epoxy and a popsicle stick! Your USB Flash Drive need never fear the washing machine again if you waterproof it... if you've got ten minutes and a popsicle stick, you can do this!

Although the modern beer keg has been with us since the 1960's the technology surrounding it has advanced much. Sure the materials might be different, and the gas mixture more suited to wide variety of ales, brews and beer, but really it's still a big metal cylinder that's heavy and difficult to control access to. So we figured we put a few 21st century bits of technology on the thing and turn it into a mobile and easily controlled beer dispenser.
