Note: Due to the overwhelming response, I have decided to form a company OnLatte, Inc. Our new address is Note: if you are willing to register, you can help me to promote this idea on MyStarbucksIdea site Long time ago, I saw a great video about “Latte Art”, and figured that I absolutely must build a machine capable of printing the most beautiful art on top of my latte. So I bought a used x-y flatbed plotter (Philips 8155) on eBay and a great book by Matt Gilliland, titled “Inkjet Applications”. I put the two together, to get this nice Latte Art Printing Machine. Here is an brief video my friend Mike took (sorry for poor quality, off topic discussions, and amused laughter of my friends): In this video I print out Starbucks logo for fun.

So the question is, how can you build a system like this? You will need: 1) An old flatbed plotter (in my case it was Philips 8155) – make sure it has real x-y translation stage.

" Don't worry, we know exactly what we're doing here. Everyone expects pranks in April and the days leading up. No one expects a prank in the middle of summer. Muhahahahahahaa... Oh, and if you get fired because of one of the pranks, it's summer time. Disclaimer: Use the pranks below at your own risk. 1 - I Know Where You Are...

The Prank: How creepy would it be if your computer suddenly talked to you when you walked towards it? What you need: >Access to their Bluetooth phone and Mac. The Steps: 1) Find, or create, an .aiff sound that you want to play when your victim approaches their computer. 2) Save the file you found, or made, in ~/Library/Sounds. 3) Open script editor (Applications > AppleScript > Script Editor), type "beep" and then click compile. 4) Download Proximity and launch it. 5) Pair their phone to Proximity by selecting "Change Device. " >Spark>Access to victim's Mac. Tilted Twister. Arduino. My older son recently started school and needed his own desk for doing homework. I wanted to make something nicer than a simple tabletop with legs, and realized that I could also build in a bit of fun for when the homework is finished.

Both my boys and I still had space travel on our minds from our summer trip to Kennedy Space Center. For this desk project, I decided to go with a NASA theme. I researched the Apollo Program as well as NASA's Mission Control Center, and designed my own console roughly based on those. I say "roughly" because the actual Mission Control does more monitoring than controlling, and isn't awash in the whiz-bang rocket noises young kids appreciate. I took great liberties and made more of a "space-themed" play console than an accurate simulator. The desk resides under my son's loft bed (which I also built), and stays closed until the homework is finished: When playtime begins, the lid flips up to reveal the Mission Control console:

Mindstorms NXT building instructions. Downloads | NXT-based Creations | Building Instructions. Projects for NXT 2.0. Teagueduino: Learn to Make by Teague. Teagueduino is an open source electronic board and interface that allows you to realize creative ideas without soldering or knowing how to code, while teaching you the ropes of programming and embedded development (like arduino). Teagueduino is designed to help you discover your inner techno-geek and embrace the awesomeness of making things in realtime — even if you’ve only ever programmed your VCR.

Teagueduino makes making things really simple. Want to build a light-controlled alarm clock? A harmonic music generator or a light that changes color based on temperature? How about a magnetic field meter or a robotic frog? These are just a few of the things that have been created so far, and with integrated project sharing you can always share your work or see the latest things being built as you go! Just plug in a sensor to one of the input ports (for example, a knob), hook up an output device (a speaker, perhaps?) Teagueduino makes learning about electronics and programming intuitive.

How To Become A Hacker - StumbleUpon. Copyright © 2001 Eric S. Raymond As editor of the Jargon File and author of a few other well-known documents of similar nature, I often get email requests from enthusiastic network newbies asking (in effect) "how can I learn to be a wizardly hacker? ". Back in 1996 I noticed that there didn't seem to be any other FAQs or web documents that addressed this vital question, so I started this one.

A lot of hackers now consider it definitive, and I suppose that means it is. Still, I don't claim to be the exclusive authority on this topic; if you don't like what you read here, write your own.

AppleScript: Beginner's Tutorial. The following online materials are exerpted from the Apple Training Series book . Consider this chapter a “book within a book.” If you don't read any other chapter, read this one. It has been designed to give you a quick but thorough introduction to AppleScript through a short, fun, hands-on tutorial. In 25 minutes you’ll learn what AppleScript is, how it works, and how to write basic, functional AppleScript scripts with confidence. To accomplish this goal, you’ll learn the fundamentals of AppleScript, and then put them to use as we step through the creation of a Finder Toolbar script, that you can use to instantly reset a cluttered desktop window display to a predefined window set. AppleScript is a language used to automate the actions of the Macintosh Operating System and many of its applications.

How it works... Scripts are written in the Script Editor application, a free utility included with every copy of the Mac OS. The Big Picture On the Macintosh computer everything is an object.
