Geek on the Cheap #126:
Best Retail Computer – Potential Hackintosh

Sunday, February 21st, 2010

My new computer - goofy lighting and all

If you’re editing video, you’re probably using Apple’s Final Cut Pro. It’s used by everyone who’s serious about video editing, from Francis Ford Coppola to my friend Julie’s son. (And me — a serious beginner on the software.) But what if you don’t already own a Mac? Over the past few months, I’ve been doing my video editing at the local community media and technology center. I can book four-hour blocks of time, for free, two times a week. A fantastic resource, but hardly an ideal situation. Especially when I need to make a tiny edit and can’t without waiting days.

So if you’re doing a fair amount of video editing, does it make sense to switch from PC to Mac?

Not for me. I refuse to pay $2500 for a desktop — the starting price of a quad-core Mac Pro. This entry Mac Pro includes a paltry 3GB of RAM, a NVIDIA GeForce GT 120 512MB video card and no monitor, of course. Hardly any hardware for a $2500 layout.

Instead I decided to build a Hackintosh — a Mac clone that can run the Apple operating system, which means it can then run Final Cut Pro. I planned to build this new box over my week off between Christmas and New Years, so I checked out the build at LifeHacker (How to Build a Hackintosh with Snow Leopard, Start to Finish [09-03-09]) and another at Videoguys (DIY7.7: Intel Core i7 8-core [03-24-09]). I combined the ideas of both then priced out the components and came up with an i7 box that would cost about $1100. A lot better than $2500, right?

That’s what I thought until I ran across iBuyPower while jumping between Tiger Direct and Newegg.

I priced out the same build for about $50 less than building the system myself, plus it came with Windows 7.

Wow! I’ve had the box for about a month now and I can report that it has zero problems. I must admit I was looking forward to building my new box, but I must also admit that I was very happy to just plug in the computer and get down to the business of finding out which of my software programs would actually work with Windows 7 (all of them except Adobe CS2, the most expensive, but it was time to upgrade anyway).

I haven’t installed Snow Leopard on the box yet; I’m so pleased with it as is that I’m a little afraid to Applify it. However, the build meets all Mac specs, so I don’t expect any problems (famous last words, right?). I’ll be following these instrux at LifeHacker — Install Snow Leopard on Your Hackintosh PC, No Hacking Required.

Stay tuned for part 2: Installing Snow Leopard.

Last Bit of MIT – Quantum Mechanics Made (Sort of) Easy

Monday, February 15th, 2010

Okay, this is my last MIT-related GoC for the near future. I couldn’t resist this post because a friend of mine is editing a book by Walter Lewin, the well-known MIT physics professor (emeritus) whose lectures plunk physics solidly into the realm of the knowable for the average person (or undergraduate).

And who doesn’t want to impress her friends and colleagues with an understanding (however shallow) of quantum physics? That’s what I’ll be gabbing about at Mah Jongg next weekend, filling my competitors ears with a fuzzy explanation of Heisenberg’s uncertainty principle as they try to make a hand. (Clever strategy, no?)

And I’m challenging you to hop to the head of the class with this lecture, the last in Lewin’s course on classical mechanics, which is available in its entirety through MIT OpenCourseWare. And for those of you who prefer to read, you can find the entire transcript here.

Why should you care about quantum mechanics? Because, as Lewin says, “[it's] a bizarre world that we rarely experience in our daily lives, because we are used to basketballs, baseballs, tennis balls [classical mechanics].” In other words, quantum mechanics is not intuitive. And this is an important concept in and of itself for practicing science, politics and life: Intuition does not equal truth.

But enough tiny philosophy. Next week we’re back to brass tacks – an inexpensive computer build you don’t have to build.

More TEI – Demos, Workshops & Kits

Sunday, February 7th, 2010

NOTE: I switched out computers this weekend and Adobe is not allowing me to reinstall CS2 (yes, I’m still using 2). So no pics this week because I’m Photoshop-less.

It’s now been an entire week away from TEI and I must admit the glow is starting to fade as the day-to-day toils of life clog my mind. But here are some great links to take me back to it all:

TUI Blog by form+zweck
Written mainly by Christian Zöllner, one of the creators of the SMSlingshot which was demoed at TEI (it allows you to type in a message then slingshot it onto a wall).

Groove Mechanic: TEI Demo Roundup
This blog by Abel Allison, one of the creators of the TessalTable, offers another nice roundup of the demos.

Technology Review: Malleable Maps, Artistic Robots and Bubble Interfaces
Videos of five of the demos — 3-D Responsive Map, Interactive Art Cobots, Tangible Jukebox (very cool), Augmented Reality Pattern Table (very very cool), Soap Bubble Interface (see my video from last week). Unfortunately, the vids are narrated (oddly) by a monotone voice that makes what’s being described sound almost boring.

Humanism at the MIT Media Lab’s TEI Conference??!
Last but not least, Jon Kolko looks back at the conference and comes up with the conclusion that “the geeks are begging for design.”

KITS

Below are a few kits available from people who gave related workshops at TEI. I would have loved to have taken these workshops, but we could choose only one. Oh well, at least I can pretend to conduct my own pseudo-workshop at home. And you can, too.

Fabric Sensor Kits
Hannah Perner-Wilson is currently a grad student in MIT’s High-Low Tech group (read this interview with Hannah from Fashioning Technology). She held a workshop at TEI on making textile sensors from scratch.

Fritzing
Sounds like fun, doesn’t it? Fritzing is open source software that helps non-technical designers move from physical prototype to actual product: creating a printed circuit board with the appropriate circuit and desired shape.

Vital Threads Biofeedback Apparel
Sean Montgomery is a recent neuroscience PhD who likes to stand out in a crowd. I had a blast meeting him at TEI and seeing his devices in person. On this site, you can get kits for his Truth Wristband (turns from blue to red as the wearer becomes aroused) and Heart-felt Apparel (detects your heart beat and displays it as a pulsing LED heart on your t-shirt).

Top 30 Wiimote Hacks
I also missed the Wiimote Hackery workshop and the presenters — Amanda Wiiliams and Daniela Rosner — don’t have any kits. But Wiimotes are crazy-easy to hack, so here are Hack N Mod’s top 30 Wiimote hacks (my favorite is #2 Wiimote Controlled Lawn Mower).

Have fun hacking and don’t forget — if you’re not pulling your hair out at some point in the making, you must be doing too many things right.

TEI ‘10 – Best Conference Ever

Monday, February 1st, 2010

TEI Studios from jay silver on Vimeo.

So I went to the TEI Conference last week and had a fantastic time — learning, meeting people, having braingasmic fun. This conference concerns itself with the interlinking of the digital and physical worlds through tangible interfaces, whole-body interaction and interactive surfaces.

There were about 230 attendees from around the world and everyone was brilliant, accomplished and collaborative. Although English was the lingua franca, people were gabbing in German, Japanese, Portuguese, Swedish, Chinese (just to name a few) — a refreshing breeze through my Brocas since I live in very white Vermont.

Of course, right off the bat, I went to the wrong building. Somehow I didn’t know that MIT has built a brand new Media Lab building, a cross between an Apple store and Kubrick’s 2001 — very white with lots of glass, a floor-to-ceiling central atrium with wrap-around labs and walkways criss-crossing from one side to the other. Apparently I have no sense of direction at all whatsoever, because the second I was off the conference floor I was lost. (Though quite happily so.)

A couple of photos I took from the ground floor - click the image to see a slideshow

I had planned to tweet during the papers, but I couldn’t get past the rudeness of having a computer in my lap while someone’s presenting. I know from first-hand experience that it’s awful to look out at an audience and not find anyone looking back at you. And I didn’t tweet from the hotel because you had to pay for wifi, which I refused to do (yes, I’m cheap).

However, I did shoot a few videos, and this week’s Geek includes a couple that describe the breadth of the work shown at the conference.

The Soft and the Hard

We all use interfaces every day — our phones, microwaves, light switches, cars. We push a button, click a mouse, swipe a finger. We expect them to be where they always are which is, in fact, considered to be good design.

However, what if an interface is temporary, ephemeral? Do we really need to know where it is all the time if we know what it is? And what if the interface requires great care in its handling? Does this make it more precious or the work it accomplishes more dear? These are just a few of the questions that come to mind with the work of Tanja Doring, an integration of art and technology:

With Soumitra Bhat, however, we have a lovely synthesis of music, technology and social impact. He has created TouchTone, an electronic musical instrument for children with cerebral palsy. It’s a clever way of giving these children access to the joy and therapeutic benefits of making music. Normally, their limited physical abilities make it impossible for them to play a musical instrument.

These two innovations describe the breadth of work presented at the conference — from concrete applications of interaction design to more abstract ideas of how we might use the various properties of physical objects in combination with either current or projected computational and/or electronic capabilities.

Stay tuned for more next week — workshops (and kits). The video at the top is just a tease of how cool they were.
