Pop Can Art

Some people are much more artistic than I am. Here is a large example of can art that I would have no chance of pulling off. Very impressive work!

Hacked Coke Machines

Looks like the average joe can now read about Coke machine programing. Seems that the service manual is now readily available. When are companies going to learn to guard this material better?
“COIN PAYOUT ROUTINE
This function allows you to dump coins from the coin mechanism.
Press select button 4 to enter mode and the lowest coin value dispensable will show on the display.
Press select button 2 or 3 to scroll through the different coin values available.
Press and hold select button 4 to dump the coins whose value is shown on the display.
Press select button 1 will return to “CPO.”

ATM Hack

 
When the manuals are provided online and the default passwords are not changed on most system when installed you are just asking for problems. I think the main problem with this system is that you can enter programming mode straight from the keypad, this is convenient however it would be much more secure if the operator was required to unlock the front of the machine and flip a service switch.
Also with default passwords of Master = 555555 Service = 222222 Operator = 111111 you are asking for problems. Here are a few more links with information of this blunder.
Link 1, Link 2, Link 3, Link 4
I wonder how long it will take for other manufactures such as Triton to learn from this. Lilricky mentioned in the Digg post that this manual also contains master passwords, looks like this problem might be ongoing!
“I just confirmed that this does […]

Fish Controlled Robot

 
We have all seen the roach robot, well not fish also have a chance to control a robot!
“Seth Weiner’s art project is a vehicle called Terranaut. This interesting vessel is driven by the motions of a parrot cichlid in a fish bowl. A camera mounted above the tank tracks the fish’s movement and relays that information to a computer, which then drives the robot in the direction the fish was traveling. With this contraption the fish is capable of exploring land in a way never before possible. It’s one small step for fish, one giant leap for fish-kind or something.”

Drive your Roomba with your cell phone

 
As we all know the Roomba was designed to clean floors, but it can do much more. Tod Kurt has created a phone controlled Roomba.
“Ever since Bluetooth adapters for Roombas appeared, I’ve wanted to control my Roomba with a cell phone. All my recent phones have had Bluetooth. But getting a devkit for a phone was expensive and phone-specific. Trying to develop J2ME (aka “JavaME”) applications for cell phones has been a mess, especially for non-Windows users. Thankfully, Mobile Processing wraps up the ugly details, like Processing does for normal Java. It makes writing little programs for your phone pretty easy, and makes whipping up a program to control a Roomba possible.”

LEGO Rubberband Chaingun

 
This Rubber Band Chaingun is one mean machine. It seems to work very well. If anyone knows where there are building plans I would love to see them.
“The motor driven barrels start winding up to speed at the flick of a switch on the handle. Pulling the trigger unleashes a stream of rubber bands, deluging the target. The fire rate is high enough that at least half a dozen bands are in the air at any one time – the gun appears to fire a single very long chain of them. It’s as much like using a hose pipe as firing a rubber band gun. It also sounds fantastic because each mechanism makes a distinct click as it discharges a rubber band.”

Electromagnetic Disc Launcher

 
Tristan has taken some EBay capacitors and some charging components to build a cool Disc Launcher. His home made coil self destructed on the last launch but it worked very well till that point.
“This project was started in Spring of 2006. I had taken a several year break from working on any HV / EMP project. In that time I was changing jobs, getting married, and buying a house. Early in 2006 I found a forum online for HV enthusiasts 4HV.org and it sparked my interest once again. With renewed ambition and the help of 4HV.org I set out to design a more portable, electrolytic-powered, coilgun. Unlike EMP-2A which used a capacitor that weighed around 100 lbs and required nearly 10,000V to charge it, this new project will be portable and easier/safer to control. ”

Philips Light Emitting T-Shirt in Action

 
Here is a better look at the cool LED fabric that was shown last week.
“This video shows the full extent of how far the technology has gone, with different colors, how the fabric reacts to touch (which is surprisingly like a normal fabric) and how LumaLive can be made useful on other things like sofas or in other places around the house. For example, a Lumalive clock on your Sofa would be very useful. After watching the video, you’ll know why this is technology is called LumaLive. Whats next - TV in our clothes?”

Interactive Boxes

 
Natural Interaction has made some very cool inventions. This has to be one of the best!
“In the studio of the italian designer Achille Castiglioni, visitors may peek inside some of his projects just by trying to open the boxes containing the materials: the action is completed virtually, while different voices explain what you see on the table. Collaboration with Interaction Design Institute Ivrea. ”

LEGO Domino Bot

 
This is an interesting LEGO robot. Is there anything the NXT LEGO system can’t do?
“For those who do not know about the Lego Mindstorms Developer Program (MDP), back in January of 2006 Lego was seeking assistance from the Lego community on their next generation Mindstorms product (NXT). Approx 9600 people applied to become one of the 100 MDP’s. In late February, I received an invitation to participate and of course jump at the opportunity. For a few months, the group of us were under an NDA (Non-Disclosure Agreement) where we could not talk, show or discuss anything about what we had been working on in the MPD. Now that May 1 has passed, we can now open to discuss some of what we have been up to.”

The Great Ball Contraption

 
This contraption must have been lots of fun to create. The LEGO skill shines through on these modules!

Link 3
“Idea: Develop a Mindstorms/Technic creation (not competition) in which people of all building levels can participate. Each person can build one (or more) module(s). All modules will be assembled to form a large “Rube Goldberg “-ish bucket-brigade type contraption.
A Great Ball Contraption loop was assembled on FreeLug booth during LegoWorld. Thanks to a strong ItLug participation it featured 18 modules at most (Italian team had to leave on Monday morning).
The GBC worked during the 6 event days, 7 hours per day. Reliability was very good - except some errant balls of course. At the end, we noticed some gears wear and stains of black paint from soccer balls on many modules but nothing serious. My Monitor module (to be […]
