Extreme Home Engineering: How To Build Your Own TiVo

This week: How to build your own TiVo (or, How to never miss an important football game ever again.)

Building your own TiVo—or FreeVo, as some call it—is more than a dream. It's more than a trend. It's the new cool way to stick it to The (TiVo) Man while impressing your friends.

Make and Wired have published detailed how-tos. There are also several online communities like The Green Button that will help guide you through the tricky parts.

TiVo-article1.jpegFor the technology dunces of the world—myself included—I had several friends break down the jargon into simple steps we can all understand.

Your mission: To build your own digital video recorder from mail-order parts.

The payoff: An integrated entertainment system that records TV programs with no monthly fees. You can also build in various wrinkles so that it will record high-def programs and edit out commercials automatically.

Keep reading for your marching orders...

Ingredients

1. A credit card with about $500 working capital on it.

2. A computer with a media operating system. Various versions of Microsoft Media Center, Vista Home Premium, Linux Freevo, etc. will work, too. It's the operating system that's important, not the computer itself; you can even use that old one sitting in your garage. Or you can use your current home computer. But if you go that route, be sure to back up all your music and videos when you install the new media system. You don't want to lose that precious footage of Junior taking his first steps in your quest to record MTV's Spring Break. Depending on how much you plan to record, you may need more hard drive space.

3. Video card: $70 "“ Available in quiet or cheap versions.

4. A dual tuner: $90 "“ This tuner handles both standard- and high-def signals.

5. MCE remote: $30 "“ It seems like an impossible dream, but you're finally going to have ONE remote.

6. Various cables, cords, and adapters as needed. Some people also like to buy a casing to contain hold all these parts and make it somewhat attractive.

7. More relationship savvy than Dr. Phil, since your spouse/life-partner/roommate is going to wonder what the F you're doing to the TV. The best way to play it is to convince said spouse/life-partner/roommate that you're going to all this effort for them. That's what my buddy C.J. did, as he explained:

"You have to consider WAF (wife acceptance factor -- or HAF if it's the wife doing the installation). Always think about ways to make it easier for them. The right remote will make or break your system due to your spouse yelling at you about how to do certain things even if you told them three times in two days. All aspects contribute to WAF: feasibility, silence, beauty and function. Last week I just added a small program that actually skips past commercials of your recorded shows automatically. My wife was shocked when she saw what it did. It's astounding how well it works, no more fast-forwarding and rewinding to get to the right spot. She keeps saying, "˜I just keep feeling the urge to grab the remote and fast forward but it's doing it for me' with a giant smile on her face. That was the best feeling ever."

Steps

TiVo-article2.jpeg1. Install the parts (video card, hard drive, tuners) in the computer case. This just means plugging and/or attaching them to the brackets inside the case. Some people will buy a new case to hold all these parts and make a more attractive package to sit under the TV. If you're using a laptop to build your system, you'll definitely want a new case because there isn't room inside for all the stuff you're adding.

2. Install the media operating system on your computer. Once you insert the software CD into the drive, a self-install application will guide you through the steps.

3. Set up the tuners and install the drivers. The tuners are one of the items you just plugged into the case, and the drivers are the software that will run them. Again, a CD will arrive with the tuners, and you just follow its prompts. Once the drivers are installed, the tuners will pop up on screen, a la "Windows has detected new hardware."

4. Configure your media settings (timers, programs you want to record, etc.) At this point, you still have the keyboard attached to the computer, which makes setting up your preferences much easier. The first time you open up your media operating system is kinda like when you open up Microsoft Word for the first time on a computer: it asks you all kinds of questions about how you plan to use it.

5. Program your remote. No different from programming a new remote under any other circumstances. If you're using Microsoft Media Center, it can set up your remote for you.

6. Connect your computer to the TV. A matter of connecting the cables.

7. Sit back and enjoy. You've just conquered the Everest of home entertainment, my friend.

Head Case: What the Only Soft Tissue Dodo Head in Existence Is Teaching Scientists About These Extinct Birds

Of all the recently extinct animals, none seems to excite the imagination quite like the dodo—a fact Mark Carnall has experienced firsthand. As one of two Life Collections Managers at the UK's Oxford University Museum of Natural History, he’s responsible for nearly 150,000 specimens, “basically all the dead animals excluding insects and fossils,” he tells Mental Floss via email. And that includes the only known soft tissue dodo head in existence.

“In the two and a bit years that I’ve been here, there’s been a steady flow of queries about the dodo from researchers, artists, the public, and the media,” he says. “This is the third interview about the dodo this week! It’s definitely one of the most popular specimens I look after.”

The dodo, or Raphus cucullatus, lived only on the island of Mauritius (and surrounding islets) in the Indian Ocean. First described by Vice Admiral Wybrand van Warwijck in 1598, it was extinct less than 100 years later (sailors' tales of the bird, coupled with its rapid extinction, made many doubt that the dodo was a real creature). Historians still debate the extent that humans ate them, but the flightless birds were easy prey for the predators, including rats and pigs, that sailors introduced to the isolated island of Mauritius. Because the dodo went extinct in the 1600s (the actual date is still widely debated), museum specimens are very, very rare. In fact, with the exception of subfossils—the dark skeletons on display at many museums—there are only three other known specimens, according to Carnall, “and one of those is missing.” (The fully feathered dodos you might have seen in museums? They're models, not actual zoological specimens.)

Since its extinction was confirmed in the 1800s, Raphus cucullatus has been an object of fascination: It’s been painted and drawn, written about and scientifically studied, and unfairly become synonymous with stupidity. Even now, more than 300 years since the last dodo walked the Earth, there’s still so much we don’t know about the bird—and Oxford’s specimen might be our greatest opportunity to unlock the mysteries surrounding how it behaved, how it lived, how it evolved, and how it died.

 
 

To put into context how old the dodo head is, consider this: From the rule of Oliver Cromwell to the reign of Queen Elizabeth II, it has been around—and it’s likely even older than that. Initially an entire bird (how exactly it was preserved is unclear), the specimen belonged to Elias Ashmole, who used his collections to found Oxford’s Ashmolean Museum in 1677. Before that, it belonged to John Tradescant the Elder and his son; a description of the collection from 1656 notes the specimen as “Dodar, from the Island Mauritius; it is not able to flie being so big.”

And that’s where the dodo’s provenance ends—beyond that, no one knows where or when the specimen came from. “Where the Tradescants got the dodo from has been the subject of some speculation,” Carnall says. “A number of live animals were brought back from Mauritius, but it’s not clear if this is one of [those animals].”

Initially, the specimen was just another one of many in the museum’s collections, and in 1755, most of the body was disposed of because of rot. But in the 19th century, when the extinction of the dodo was confirmed, there was suddenly renewed interest in what remained. Carnall writes on the museum’s blog that John Duncan, then the Keeper of the Ashmolean Museum, had a number of casts of the head made, which were sent to scientists and institutions like the British Museum and Royal College of Surgeons. Today, those casts—and casts of those casts—can be found around the world. (Carnall is actively trying to track them all down.)

In the 1840s, Sir Henry Acland, a doctor and teacher, dissected one side of the head to expose its skeleton, leaving the skin attached on the other side, for a book about the bird by Alexander Gordon Melville and H.E. Strickland called The dodo and its kindred; or, The history, affinities, and osteology of the dodo, solitaire, and other extinct birds of the islands Mauritius, Rodriguez and Bourbon. Published in 1848, “[It] brought together all the known accounts and depictions of the dodo,” Carnall says. The Dodo and its kindred further raised the dodo’s profile, and may have been what spurred schoolteacher George Clark to take a team to Mauritius, where they found the subfossil dodo remains that can be seen in many museums today.

Melville and Strickland described Oxford’s specimen—which they believed to be female—as being “in tolerable preservation ... The eyes still remain dried within the sockets, but the corneous extremity of the beak has perished, so that it scarcely exhibits that strongly hooked termination so conspicuous in all the original portraits. The deep transverse grooves are also visible, though less developed than in the paintings.”

Today, the specimen includes the head as well as the sclerotic ring (a bony feature found in the eyes of birds and lizards), a feather (which is mounted on a microscope slide), tissue samples, the foot skeleton, and scales from the foot. “Considering it’s been on display in collections and museums, pest eaten, dissected, sampled and handled by scientists for over 350 years,” Carnall says, “it’s in surprisingly good condition.”

 
 

There’s still much we don’t know about the dodo, and therefore a lot to learn. As the only soft tissue of a dodo known to exist, the head has been studied for centuries, and not always in ways that we would approve of today. “There was quite some consideration about dissecting the skin off of the head by Sir Henry Acland,” Carnall says. “Sadly there have also been some questionable permissions given, such as when [Melville] soaked the head in water to manipulate the skin and feel the bony structure. Excessive handling over the years has no doubt added to the wear of the specimen.”

Today, scientists who want to examine the head have to follow a standard protocol. “The first step is to get in touch with the museum with details about access requirements ... We deal with enquiries about our collections every single day,” Carnall says. “Depending on the study required, we try to mitigate damage and risk to specimens. For destructive sampling—where a tissue sample or bone sample is needed to be removed from the specimen and then destroyed for analysis—we weigh up the potential importance of the research and how it will be shared with the wider community.”

In other words: Do the potential scientific gains outweigh the risk to the specimen? “This,” Carnall says, “can be a tough decision to make.”

The head, which has been examined by evolutionary biologist Beth Shapiro and extinction expert Samuel Turvey as well as dodo experts Julian Hume and Jolyon Parish, has been key in many recent discoveries about the bird. “[It] has been used to understand what the dodo would have looked like, what it may have eaten, where it fits in with the bird evolutionary tree, island biogeography and of course, extinction,” Carnall says. In 2011, scientists took measurements from dodo remains—including the Oxford specimen—and revised the size of the bird from the iconic 50 pounder seen in paintings to an animal “similar to that of a large wild turkey.” DNA taken from specimen’s leg bone has shed light on how the dodo came to Mauritius and how it was related to other dodo-like birds on neighboring islands [PDF]. That DNA also revealed that the dodo’s closest living relative is the Nicobar pigeon [PDF].

Even with those questions answered, there are a million more that scientists would like to answer about the dodo. “Were there other species—plants, parasites—that depended on the dodo?” Carnall asks. “What was the soft tissue like? ... How and when did the dodo and the related and also extinct Rodrigues solitaire colonize the Mascarene Islands? What were their brains like?”

 
 

Though it’s a rare specimen, and priceless by scientific standards, the dodo head is, in many ways, just like all the rest of the specimens in the museum’s collections. It’s stored in a standard archival quality box with acid-free tissue paper that’s changed regularly. (The box is getting upgraded to something that Carnall says is “slightly schmancier” because “it gets quite a bit of use, more so than the rest of the collection.”) “As for the specific storage, we store it in vault 249 and obviously turn the lasers off during the day,” Carnall jokes. “The passcode for the vault safe is 1234ABCD …”

According to Carnall, even though there are many scientific and cultural reasons why the dodo head is considered important, to him, it isn’t necessarily more important than any of the other 149,999 specimens he’s responsible for.

“Full disclosure: All museum specimens are equally important to collections managers,” he says. “It is a huge honor and a privilege to be responsible for this one particular specimen, but each and every specimen in the collection also has the power to contribute towards our knowledge of the natural world ... This week I was teaching about a species of Greek woodlouse and the molluscs of Oxfordshire. We know next to nothing about these animals—where they live, what they eat, the threats to them, and the predators that rely on them. The same is true of most living species, sadly. But on the upside, there’s so much work to be done!”
