Hasta La Gadget!

Thomas Edison was known for his wacky publicity stunts, but during the Christmas of 1880 he went for the sentimental rather than shock value. That year, instead of electrocuting an elephant, he brought us the first electric Christmas light display.

The Wizard’s Light Show

By the time 1880 rolled around, Edison had his incandescent light bulbs pretty well figured out, and was on the lookout for a way to advertise them. To display his invention as a means of heightening Yuletide excitement, he strung up incandescent bulbs all around his Menlo Park laboratory compound, so that passing commuters on the nearby railway could see the Christmas miracle. But Edison being Edison, he decided to make the challenge a little tricker by powering the lights from a remote generator eight miles away.

Two years later, an Edison crony named Edward Johnson displayed the first electrically illuminated Christmas tree at his home in Manhattan. The then-impressive 80-light display girded a very unimpressive Charlie Brown Christmas tree (I mean really, look at that thing). And as you might expect, Johnson’s feat was also intended as an advertising tool.

The tradition of stringing electric lights may have started as a Christmas thing in America, but now it’s a global phenomenon used for all kinds winter festivuses (festivi?). It’s a practice we take for granted—come December, they’re everywhere. The evolution of the Christmas light parallels that of the light bulb, with some remarkably ornate—OK, tacky—variations. But regardless of how they look, one thing’s for certain: They’re a much better option than sticking a candle in a tree.

In the Beginning, There was Fire

Today we look at Christmas lights and think “Oh, those are pretty.” But the tradition of lighting lights in the winter months didn’t start off with aesthetics in mind. December is the darkest month of the year with the shortest days. People living without central heating in the 12th century were understandably unhappy when the sun went down and plunged them into the cold depths of night. Way back during the winter of 1184 was the first recorded lighting of the Yule Log [PDF] in Germany. The burning log was seen as a symbol of the sun’s promise to return. It probably didn’t hurt that a big burning hunk of wood makes for a pretty good heat source.

The Christmas tree has a whole story behind it that we won’t get into here. (Fun Fact: they were originally hung upside down from the ceiling—hilarious!) Long story short, Christians had lights, they had trees, and in the 17th century, they decided to put the two together.

Unfortunately, the only way to add Christmas lights to a tree back then was with candles. Obviously, this was a pretty bad idea. So bad that, unlike today, the tree would only be put up a few days before Christmas [PDF] and was promptly taken down afterwards. The candles would remain lit only for a few minutes per night, and even then families would sit around the tree and watch it vigilantly, buckets of sand and water nearby. It’s kind of like the old-timey equivalent of deep-frying a turkey: People knew it could burn their house down, but proceeded to do it anyway.

By 1908, insurance companies wouldn’t even pay for damages [PDF] caused by Christmas tree fires. Their exhaustive research demonstrated that burning wax candles that were loosely secured to a dried-out tree inside your house wasn’t safe. At all. Electric Christmas lights were becoming a viable option for some Americans. They weren’t perfect—incandescent bulbs can get plenty hot, and sparks from malfunctioning strings can still light up a dry tree—but it was a much safer option than lighting multiple fires so close to their favorite fuel.

Keep in mind that by “some Americans,” I mean the extremely rich. In 1900, a single string of electric lights cost $12 [PDF]—around $300 in today’s money. It would take the magic of mass manufacturing to create the Clark Griswold-esque neighborhood light displays would become an American tradition.

The Dawn of Tacky Lights

In 1900, eight years after General Electric purchased the patent rights to Edison’s bulbs, the first known advertisement for Christmas tree lights appeared in Scientific American Magazine. Like I said, these suckers weren’t cheap. They were so expensive that the ad suggests renting lights for a holiday display.

Twenty-five years later, demand was up. There were 15 companies in the biz of selling Christmas lights, and in 1925 they formed a consortium called the NOMA Electric Corporation, the largest Christmas light manufacturer in the world.

Even though NOMA was formed three years prior to the Great Depression, their appeal was great enough to pull through, becoming a juggernaut that was synonymous with Christmas lights from the Depression clear through to the Civil Rights Movement. NOMA didn’t just further Edison’s vision, though. They worked hard to bedazzle, becoming the world’s biggest manufacturer of the bubble light—arguably the first great mass-produced tacky Christmas decoration.

Though NOMA is no more, these psychedelic bubble lights are thankfully still in existence. These colorful round plastic cases hold an unseen bulb, while a candle-shaped vial of clear liquid protrudes upward. As the bulb heats up, the liquid—usually methylene chloride, a chemical with a low boiling point—also heats up, so that the vial would bubble, flickering like the candle it was supposed to replace.

Alas, in 1968 the NOMA Electric Company stopped manufacturing lights, and the bubble lights became more of a novelty, soon to be joined by a host of ridiculously shaped Christmas lights, including chili peppers, flamingos, beer cans and a miniaturized version of that leg from A Christmas Story.

With NOMA, the tacky Pandora’s box had opened, and even people who didn’t spring for bubble lights or their Tex-Mex successors have done wonders with the decidedly more standardized sets we all know today. One they were weatherproofed for outdoor use, it was only a matter of time before they were stapled to every square inch of house, hearth, tree, even truck.

The Lights You Know and Love

Incandescent lights are the ones that started it all. Even though they’re well over a hundred years old now, the technology largely remains the same. The shapes and sizes of the bulbs, on the other hand, have been in constant flux. Now we’re left with three major types of incandescent Christmas light bulbs, as described by the excellent guide at JimOnLIght.com:

The Mini/Fairy Light: This is the big kahuna. If you haven’t seen one of these by now, then you’ve probably never seen Christmas lights. Traditionally, the set is wired in series, hence the age old problem where if one bulb goes out, the rest won’t light. But it’s not hard to find sets that are wired in parallel nowadays.

These guys also have a lo-fi twinkle method built in. That little red-tipped bulb that comes with each set is made in a way that as the filament heats up, it rises and breaks the circuit. That, of course, shuts of the rest of the lights. When it cools down, it falls again to complete the circuit, and the lights (wait for it…) come back on. Physics 101.

C7: Again, an incandescent light that comes in a different-sized glass housing. These are about the size of your thumb, and work in almost exactly the same way as a mini light.

C9: You get the picture by now. Same shape as the C7, but slightly bigger.

LED lights have been growing in popularity for the past few years. Regardless of what you think of their light output, there’s no denying that they’re much more energy efficient than incandescent bulbs, and give off less heat. And who knows, maybe someday they’ll match the color temperature of good-ol’ tungsten lighting. Until then, here’s what you’ll be looking at, again according to the guide at JimOnLight.com:

5mm: These are the LED equivalent of incandescent mini-lights. They’re small LED bulbs in a plastic enclosure. Usually the “white” level is waaaay off from the “white” of incandescent lights.

G12 and G25: Just like with incandescent lights, you’re going to find a whole lot of the same with LEDs, just in different shapes and sizes. These are globe shaped plastic enclosures, G12 is pictured.

C7: You’ve seen these before, except this time there’s an LED inside.

You’ll find a bunch of crazy light designs out there, but 99.9% of them are just plastic enclosures that are illuminated by these types of bulbs.

A Long Way From Candles

The basic foundation of the Christmas light, the incandescent bulb, hardly changed for nearly a century, and is only now undergoing is first major revolution, as we we start replacing our old tungsten lights with energy-efficient LEDs. Yet, in that same time, we’ve gone from sticking burning candles in a tree to creating massive, computer-controlled—and completely excessive—light displays like this:

One thing’s for sure: No matter what the technology at hand, no matter what the reason to celebrate, the human desire to light up trees and houses in the cold darkness of the winter months will forever be a source for amazing—and often hilarious—innovation.

Google Voice, which lets users consolidate all their phones under one number, archive your texts and voicemails, and much, much more, is two things to most people: vaguely promising, and totally confusing. Here’s how to make the switch, in plain English.

The Pitch

It doesn’t really help to describe Google Voice in terms of what it is—a bizarrely fragmented hodgepodge of different telecom and internet technologies, drawn together by Google—so you just have to start with what it does. In short, it can completely change how you use your phones, more or less for free.

• It can give all of your phones the same number for incoming calls. Google will assigned you a new, Google Voice-specific phone number for free, which you can forward to as many phones as you want. What always drives the point of Google Voice home for people is when I have them call my number, which causes three of my phones to ring at once. You can keep this number forever, too, without ever having to worry about porting it from carrier to carrier.
• It can give your phones the same outgoing number as well, with which you can make free domestic calls (well, sort of—more on that later), and very cheap international calls. Since Google Voice routes your calls through their phone system, they can connect you directly to cheap VoIP services to the rest of the world. It seems like you’re just making a regular call, but behind the scenes you’re doing something more akin to Skyping. End result: money saved.
• You can send and receive unlimited text messages for free. To make things even better, they’re all all archived in your online Google Voice account, where they’re fully searchable.
• It’s got the best voicemail system in the world. Leaving a message at a Google Voice number is nothing like leaving your voice on a regular voicemail service—that is to say, it’s not like sending your voice into a barely accessible technological horror pit where it might get listened to, but will probably be ignored. No, Google Voice is different: It stores your messages online, and converts them to text (which can then be sent to you as an SMS or an email). You can archive, forward, delete or save these messages from a simple interface on your phone or computer. Think of it as Gmail, except with voices. Plus, it’s flexible in lots of little ways—you can change your voicemail greetings on a per caller basis, for example, or opt to listen to voicemails as they’re being recorded.
• This voicemail system isn’t just for Google Voice numbers, either—you essentially replace your carrier voicemail with Google Voice voicemail, without using a new number. It’s brilliant.
• You have full control over your calls. You can record them for later listening, and have them transcribed into text.
• You can screen callers. You can block numbers, or have callers record their names for your approval. You can have certain contacts only forwarded to certain phones,

Each of these features is compelling enough on its own—together, they’ll totally change how you use your phones, changing you from a mere mobile customer to a full-on switchboard operator, self-spy, info hoarder and telco executive. It’s like you run your own little phone company, just for yourself. For free. Spectacular.

The Catch(es)

Now that I’ve got you all riled, it’s time for me to pour an icy bucket of water down the front of your pants. Google Voice, as incredible a concept and service as it is, isn’t perfect. In fact, there are a few things you need to know and accept before taking the dive, and they might be dealbreakers:

• You can’t use your own phone number. At least, not in the way you wish you could. In an ideal world, you’d be able to port your old cellphone number to Google Voice, and have that—the digits people have been using to get in touch with you for years—be your new all-inclusive point of contact. You can’t do this yet. For now, the closest you can come is to port your voicemail to Google Voice. That means that your T-Mobile, AT&T, Verizon or Sprint number’s voicemail can be outsourced to Google, but not its calls. You can unify all your phones under your new Google Voice number, but that means you have to switch. Along with the basic inconvenience of telling everyone about your new number, you’re trusting an awful lot in a beta service, the terms of which could change quickly and without notice. It’s not something I worry about, but it’s not nothing, either.

• You can’t record calls that you’ve placed, just calls that you’ve received. And every time you initiate recording, Google Voice notifies the other person on the line. This is all makes perfect moral and procedural sense, but just in case you had the impression that there were no limits on your recording abilities, well, there are.

• The mobile app situation isn’t ideal. There are apps for Android, BlackBerry, Windows Mobile and iPhone via jailbreak, and they all work. That said, they’re not perfect—they can be slow, poorly integrated, glitchy, or hard to figure out. And since they’re supposed to replace the dialer on your phone entirely, this isn’t wonderful. The online mobile interface is a good fallback for placing calls and sending texts, but navigating to that adds an extra step to any call or text that can get tiresome after a while.

• Lastly, the way American phones work, you’re still going to end up paying for your minutes, somehow. Just because Google Voice says you can make free domestic calls and cheap international calls doesn’t mean that you actually can: in both cases, you need to dial out to Google Voice’s external system in the first place, which means you’re still using your monthly minute allotment. There are ways around this which I’ll discuss later, but Google Voice, as good as it is, isn’t magic.

Discouraged? Don’t be. Google Voice is still well worth you time and effort, and it’s only going to get better. Now, for God’s sake let’s get started already.

The Process

Signing up. This is simultaneously the easiest and most irritating part of Google Voice: It’s still invite only. Lucky for you, “Invite” in this case doesn’t mean you actually have to wait for an individual to select you from the masses; it’s just Google’s way of saying their keeping the signup pace down at manageable levels while the service is still in beta. Just submit your address, after which Google “anticipate[s] that it will be a short wait before you receive your invitation.”

What’s a short wait? My invite took about four days. Some come within 48 hours. At worst, they take about two weeks. Lots of you will have already received your invite, and just not done a whole lot with it—you guys can keep reading—while the rest of you should just bookmark this post, and come back to it once you get your invite. Protip: check your spam filters.

—

Ok, hello again, people I was talking to anywhere between two seconds and two weeks ago! How are you? Now that you’ve got your invite, you can log in to your Google Voice Dashboard. It’ll look familiar if you’ve used any Google Service before:

Logging in. Follow your confirmation link, or navigate here. Click around for a while to get a feel for the interface. This is how you’ll manage your phones from now on. It’s liberatingly simple.

Picking your number. You’ll be given a choice of numbers, which you can choose from practically any available area code. Choose wisely: this will be your primary number from here on out. Choosing your first number is free; changing it in the future will cost you $10. Boo, waah, etcetera! But really not a huge deal.

Adding your phones. This is assuming you want to forward a single number to all your phones, which is kind of the point here, so: Go to the Google Voice settings page (up in the upper right-hand corner of the screen. In the first section, called “Phones,” click “Add a Phone” or “Add Another Phone.” Give it a name “My iPhone” and enter its phone number. That’s it.

Now you’ll be given a passcode, which you’ll use to authenticate your existing phone. Clicking “Connect” will call your phone from your Google Voice number, and a friendly robot will ask for you code. Enter it. That’s it!

Setting up your voicemail. Now that the phone is added, it can accept calls directed to your Google Voice number. If the call is ignored, it will forward the voicemail to Google Voice, where it will be stored online. Alternately, if you only want to use Google Voice for voicemail, you can disable the calling feature (by unchecking the box next to the phone), and set up the service to hijack your actual cellphone number’s voicemails—even when the call didn’t get routed through Google Voice.

This is much easier that it sounds: Just click “Activate Google Voicemail” next to your newly-added phone, and enter the number they give you exactly as it’s written, symbols and all. Once you “call” that number, you’ll get some kind of message on your phone. On the iPhone, it looks like this.

Your voicemail has been switched—all you need to do now is set up a quick bookmark in your mobile phone to Google Voice, which provides a functional, if sparse, interface for your Google Voice messages. It’s like visual voicemail, except through your browser. (Or a mobile app, which I’ll get to soon.)

Choosing the rest of your settings. Now you’ll see your phone listed under the “Phones” settings tab. The other tabs contain a few pages of settings for your Google Voice account. How you toggle these is up to you, but here are the most important ones: If you want to forward SMSes to email, you’ll have to enable that in the “Voicemail and SMS” tab; call screening settings are located under the “Calls” tab; and international call credit can be added under the “Billing” tab, from a credit card.

Finding your feet. Take some time to experiment with some of Google Voice’s core features now. Place a call using the button at the top left of the Google Voice homepage. Enter your recipient’s number, and choose which of your phones you’d like to place the call with. Google Voice will call your phone first, which upon answering will immediately call your recipient’s phone, which will think it’s getting a call from your new Google Voice number. It might sound odd in writing, but once you see it work, it just kind of clicks. You can also place these calls from the mobile web interface, without a computer. Texting is more direct—you can send those directly from the web interface without any intervention from your phone.

Placing calls. The aforementioned methods is the most obvious, and it will reliably work. It’s a little cumbersome, especially if you’re used to just tapping on a contact and placing a call. Thankfully there are a few more ways to place calls from your phone, and have it routed through Google Voice:



• Apps: This is by far the best way to use Google Voice. Android has an official Google Voice app, as does BlackBerry.These automate the dialing/texting out process, so you don’t need to mess with a web interface—you just opt to make some or all of your calls through Google Voice, and the app takes care of the rest. Windows Mobile has unofficial clients that do the job pretty well, as does the Pre, in the App Catalog. iPhone clients are available, but they’re not approved by Apple: You’ll need to jailbreak your phone and install them from Cydia.

• The call-in method: Simply dial your new Google Voice number from your cellphone or landline, press 2 once it’s connected, then enter the number you want to dial. This is less convenient than the web interface method, even, but it’s vital to the next one:

• The contact method: This is a little cheat to automate the aforementioned process. What you’re doing, basically, is saving your Google Voice number, a pause, the number 2 (which selects “call another phone” from the Google Voice automated menu tree), a pause, then your recipient’s number.

Adding a pause is different on each phone—on the iPhone, for example, you need to save a number as a contact, and in the number editing screen, press the “+*#” button at the bottom left of the keypad. The zero will be replaced with a “pause” button, which when pressed inserts a comma into the number. Google is your friend for this one, though most smartphones make the option available in their respective contact editing screens.

• The 406 method: Have the person you want to text send a message to your Google Voice account. When you receive the message, it will be from a number you don’t recognize, with the area code 406. It will be labeled with the sending contact’s name, and any replies to that number will return to the person who sent them, but the number is completely new. This is a Google Voice alias, which you can use forever: Just save it as part of your friend’s contacts—perhaps as a secondary cellphone or a work number, whatever you can remember—and use it as their primary contact number when call through GV.

Sending Texts. Again, using the web interface is a great way to send texts, as are the mobile apps. But the best solution? The 406 trick listed above works for SMSes too.

The Hacks

As you’ve probably noticed, Google Voice is kind of a loose system—and a system that’s ripe for a little gaming. There are two methods that currently work for getting truly unlimited, free calls over Google Voice. This is where things get really interesting. Interesting in a good way for you; interesting in a terrifying way for the phone companies.

• The Calling Circle Method: You know how some carriers let you designate a few contacts that don’t count toward your monthly allotment of minutes, like T-Mobile MyFaves, or the AT&T A-List? By making your Google Voice number one of your friends, you can filter all your calls through Google, whether they be free domestic calls or cheap international calls. Once your Google number is added to your circle, making free calls is simply a matter of dialing into your Google Voice number and, using Google’s audio menu system, dialing through to your recipient. (The contact method listed above will work too.)

To make incoming calls—including outgoing calls initiated from the Google Voice web interface—free, you’ll need to change your Google Voice settings under the “Calls” tab. Select “Display my Google Voice Number” under the “Caller ID (in)” setting, and you’re good to go. A full setup guide for the calling circle method can be found here.

Note: Designating Google Voice as one of your preferred contacts may be against your carrier’s user policies—check with them if you’re concerned.

• The VoIP method: By signing up for a number with free VoIP service Gizmo5 and adding to to your Google Voice account as a phone, you can place unlimited free calls from your VoIP number to landlines. You can also forward the calls through to Skype, if you’d prefer. This isn’t a solution for mobile phones, but it’s a great way to make yourself an effectively unlimited VoIP landline for free. Lifehacker’s got the whole rundown here. UPDATE: Registrations for Gizmo5 have been closed. Sorry!
