It looks like there’s now a “pre-pay” solution to saving some money on by purchasing gas in advance.

You can go to MyGallons.com to purchase your future gas at current prices.

The high price of gasoline has some U.S. drivers looking to the future.

A recently introduced service called MyGallons.com allows drivers to fill up their tanks sometime in the future but at current prices, using a debit-like card which banks gallons rather than dollars.

“The price of gasoline was changing all the time. It seemed unpredictable,” Steven Verona, founder and owner of the Miami-based company, said on Monday.

Here’s an interesting photography hacking tool.  Basically the image fulgurator inserts messages onto other people’s photos by displaying the letters at the exact moment the innocent photographer’s flash goes off.

Kind cool for sending messages in a tourist attaction.

It’s a reactive flash image-projector… or, to put it another way, a real-world hack of other people’s photos. Sounds sinister, looks sinister… works great. Adapted from a flash gun and an old SLR, it senses the flash of someone’s camera, and then quickly illuminates itself, projecting images or text onto the object that was being snapped. The video of bemused tourists in Berlin, peering in confusion at the screen of their digicams is priceless.

Here’s a real great way to “hack” someone’s computer.  (It’s Friday, anything goes)

Well, it looks like the guys over at Firefox forgot to add the back and forward button.  (I’ve noticed on the Firefox 3 Beta version and the official version now…)

It’s really annoying for people like me who like the back/forward button, here’s how to put that button back where it belongs:

First, goto View->Toolbars->Customize

Then simply draw the back/forward button on to any place you want to put it and press “Done”.

It’s pretty simple but a lot of people don’t know how to do it so this should help you get those buttons back.

Remember the industrial robot that could swing that big ass arm? Well, here’s another one but is more sensitive for precise control.

This is a small presentation of a university project I have worked on for the last 6 months. Using a real-time system the orientation of the Wii Remote is polled and sent to the Stäubli TX 60 industrial robot. The concept is stolen from a game named Kororinpa but the graphics are little more realistic This was done at the chair Robotics and Embedded Systems Knoll of the Technical University of Munich.”

Apparently, some electric and electromagnetic doors can be opened easily with these giagantic magnets.

The ‘ring of the devil’ is capable of attacking this kind of electronic motor lock on two ways.

Scenario 1: An electronic motor is nothing more then a metal part on an axe that turns because of a changing magnetic field. Turning electro magnets on and off will generate a pulling force on the metal part, making it rotate. The ring does the same thing. By turning the ring, the metal part in the electro motor starts turning, opening the lock. As Rop suggested in the comments of the previous posting, a bunch of bigger magnets and maybe a high-speed drill can amplify this effect some more.

Scenario 2: A dynamo is nothing more then a coil charged by a changing magnetic field. So any coil in the lock will start generating current when a magnetic field is rotating around it. If the coil is in the path of the electro motor, it might generate enough current for the motor to start turning.

Currently we are testing with this magnetic ring. Jord Knaap and Han Fey already found one other electro/mechanical lock that seems to open under some conditions with this technique. As with all problems we personally discover, we are first going to notify the manufacturer to give them some time to analyze the problem. But with the ‘devils ring’ out on the free market it will probably be a matter of day’s/weeks before other people will find (and report) locks that are vulnerable to it.

Here’s a fun DIY for experimenting with some high voltage from spare TV parts.

In this Instructable you will learn how to make a High Voltage High Frequency power supply in 5 minutes and for less than $20.

All you need is a compact fluorescent light (CFL) and a flyback transformer.

Flyback transformers are found in TVs and CRT monitors. They make the high voltage, high frequency current necessary to trace the electron beam across the screen. They are small and compact, and you can take them out from an old computer monitor or TV.

Okay, here’s a video of how you can order Dominos PIzza via your Linux/Unix command line.  Why?

So you can setup cron-jobs daily and get your pizza ordered automatically.
