Print your photographs in 3D

Step aside, home photo printer! The age of the 3D printer is just beginning. But then what are you supposed to do with all those digital photos sitting on your hard drive?

Well, thanks to Amanda Ghassaei of Instructables -- who showed us how to make a 3D-printed record -- you can try printing them in 3D. Using an Objet500 Connex 3D printer that prints at 600dpi, along with ModelBuilder library and the Processing open-source programming language, Ghassaei converted her photographs into a printable topography.

DIY Ewok cat hat: May the feline be with you

Ewoks aren't real. This is unfortunate. Sometimes we just have to make do with what we can find laying around the house. For Instructables user carlsonbryant, that happened to be a cat and some scrap leather.

Carlsonbryant lays out the steps for turning your regular domestic feline into a denizen of Endor. The ingredients are basic. You need a piece of leather or leather-like material about a foot square, a leather punch, scissors, and some type of twine or string to hold it all together.

I took on the mission of building my own Ewok cat hat using the instructions. It took about 20 minutes of drawing on a old piece of chamois, cutting out the pattern, punching holes, and tying it all together. The cats hovered around me as I worked, batting at the leather and strings.… Read more

Monitor hack hides your private computing parts

While it may appear that Instructables contributor dimovi has been staring at a blank, white computer screen for hours, he's actually getting some super secret work done.

Dimovi hacked an old LCD monitor with a knife, paint thinner, superglue, and a pair of 3D glasses pilfered from the movies to create a privacy screen that keeps prying eyes at bay.

I know this all sound very MacGyver-ish, but it's actually pretty simple.… Read more

Capture the action on your desktop

ScreenFlow is a popular screen-recording and editing tool for creating screencasts, such as presentations, tutorials, and product demos, on your Mac. This app can handle every aspect of pulling together a screencast, from high-quality screen capture (including the ability to grab iSight and DV camera data, and mic and computer audio) to editing and exporting, with built-in YouTube publishing.

Thanks to ScreenFlow's fairly intuitive interface (now with even more time-saving shortcuts and contextual menus), even novice users can assemble a basic screencast. Experienced users, on the other hand, will appreciate the app's more sophisticated touches, such as the … Read more

Boy swaps third-gen iPod Touch battery for $8.59

A couple of months ago, I noticed that my third-generation iPod Touch (32GB) was having trouble holding a charge. After using it for a few hours, the battery was at about 30 percent, and if I left it sitting on my desk overnight, it was invariably dead in the morning, even after I turned Wi-Fi off.

I looked into getting a replacement battery and found out that Apple charges $79 (see complete chart of iPod repair pricing). Now I like my iPod Touch, which serves both as a Sonos remote and a remote for an old Roku player that I … Read more

Wiring and installing your car stereo amplifier

Tuesday's video blog was all about wiring and hooking up an aftermarket head unit into your car stereo, but let's suppose you want to create a big, bumpin' system. In that case, you want to get yourself an amp. And if you want to see how to hook up an amp to your car stereo, you've come to the right place, as this Web clip is a practical demonstration on how to make it happen.

This instructional clip goes over some of the tools and materials you'll need to wire and install the amp, how to … Read more

Learn music production with WinkSound

There's no lack of music instruction online. Sites like iVideoSongs and Internet-connected applications such as Garage Band, can tailor music instruction right down to the specific genre, song, and instrument of your choice. The trouble is, they don't actually show you how to make a great recording.

If you're more interested in how to use side-chain audio compression in Logic, than how to how to play "Stairway to Heaven," WinkSound.com is worth a look. The site design is a little rough, but the video tutorials are helpful and clearly organized into relevant topics (Garage … Read more

How to find how-tos on the Web

The economy is in trouble and we're all cutting back on spending, unsure of what the future might hold. We're also starting to realize that maybe doing things ourselves instead of hiring outside help is a great idea.

But if you're someone like me, building a deck in the back yard or, heck, painting vaulted ceilings, just isn't something you're proficient at. But luckily for us, there are a slew of sites across the Web that provide articles and videos that can help us complete any project.

5min.com I like 5min because I can learn about almost anything in, well, 5 minutes or less.

5min features videos from users who are experts on a particular subject. Sometimes, their expertise is buying an electric shaver. Other times, it's installing weatherstripping. Either way, you can find anything from the simple to the complex on 5min.

Although the videos are great, my favorite feature on 5min is the company's video player. Unlike some players that only let you play, stop, rewind, and fast-forward a clip, 5min's video player lets you zoom in, proceed frame-by-frame, and run the video in slow motion so you don't miss any steps. That feature comes in especially handy when you watch a video on a complex topic and the expert is moving too fast in their instruction.

eHow

eHow is a fantastic how-to site that includes both videos and articles. And although there aren't nearly as many videos on the site as other services like 5min, eHow still provides a fine alternative for learning how to get things done.

eHow enlists the help of professionals to create the more than 300,000 articles on the site. From learning how to tie a tie, to how to caulk, the site has it all. That said, if you're looking for video, you're not going to find much on eHow--it's designed to provide step-by-step text instructions. Sometimes, especially when I need to figure out how to build something like a deck, that's ideal. But for simple topics like learning how to throw a baseball, a video works much better. In those cases, I tend to use sites like 5min or Expert Village instead.

You will be forced to sit through commercials on the company's videos, but that's not a big deal--they're only 15 seconds long and run before the clip. I should also note that the site's video player doesn't offer all the extras like those that you'll find with 5min, so you'll probably find yourself moving the slider back quite often to figure out how to do something.

But video isn't what eHow is all about. The site is ideal when you want to bring instructions with you wherever you need to complete a task. Unlike 5min or Expert Village, I don't need to sit in front of my computer to see how to sand wood flooring when I use eHow; I can print out the instructions and read them. And on complex projects, having that option is ideal.

Expert Village

Expert Village is a little different from a service like 5min, which allows users to upload videos to display their expertise. Expert Village employs experts who work in fields ranging from music to home improvement who research particular topics and create short videos--usually no longer than five minutes--detailing how to perform a particular task.

The value of Expert Village's use of experts is seen almost immediately. Sure, you can find a really informative video on 5min and it might provide the same quality as something on Expert Village, but generally, that's the exception, not the norm.

According to Expert Village's internal figures, the site features over 131,000 videos that have been viewed more than 292 million times. And given the wide range of topics those videos cover, Expert Village is an ideal source for help.

One especially nice offering that shouldn't be overlooked is Expert Village's series. Unlike 5min or even eHow, some Expert Village experts stay on one topic and create a series of videos to walk you through a process.

For instance, one expert is teaching Chinese etiquette.… Read more

Podcast: Video tutoring for high-schoolers

When I think way back to my high school days, I can count on one hand the teachers who were inspiring or, at the very least, compelling. But what if teens from anywhere could access some of the best, brightest, and most entertaining teachers to help them brush up on a wide variety of subjects?

That's the idea behind Brightstorm, a Web service that recruits teachers to appear in instructional videos aimed at high school students. Subject matters include geometry, algebra, writing, U.S. history, and, of course, SAT preparation.

From the few courses I sampled, it definitely appears … Read more
