Hacks Mods & Circuitry: Page 5

Remember the 1960's American television series Batman, with Adam West as Bruce Wayne? It was waaaaay before my time. The caped crusader that I'm more familiar with is actually this one...

The cell phone may have replaced the pocket watch, but thanks to some clever mods and hacks, "old-fashioned" time telling is making a comeback. Smart watches that connect to your mobile device cannot only tell you what time it is, but also change the song you're listening to and let you know how many Facebook notifications are waiting for you.

At one time or another, we've all enjoyed the visualizations that came stock in Windows Media Player. I remember spending hours listening to my favorite album, putting the graphic equalizer on full screen, and getting lost in the flurry of colors that would dance across the screen.

Doorbells are useful and all, but most of them are boring as hell. They use the same old generic sounds to let you know when guests have arrived, as demonstrated below.

I have a pre-lit tree lit with mini bulbs at 125vac 5a 625w and i want to convert it to blue LED. I would prefer to just swap out the bulbs, but is that possible? Doesn't the power for regular bulbs and LED ones differ? I am not opposed to re-stringing the tree, but the wire has to be black, since my tree is black. Do i have to buy a blue LED string and tape off the bulbs and spray paint the wire black to achieve this, or is there an easier way to do what i want to do?

There isn't as much use for old-school four-function calculators anymore since we all have them on our cell phones now. If you've still got one lying around, you can hack it to play recorded sounds, use it to make a metal detector, or turn it into a custom name plate that says anything you want...

The Jetsons may not have gotten everything right about the future, but even though we may not have flying cars or live in the sky (yet), one thing they imagined correctly was our electronics eventually being able to understand us.

If you've spent most of your life in one geographic location, you're probably pretty familiar with the weather there (unless you're a hermit). If you live in a tropical climate (and haven't done much traveling), maybe you've never even seen snow.

Keys are on the way out. They're clunky, take up precious space, and slow you down when you have tons of identical-looking gold ones on your keyring. Everything we can open with keys can now also be opened with wireless technology in just a click—so why use keys anymore?

Wouldn't it be awesome if your glasses could detect when it's bright outside and automatically darken? Well, the technology has been around for a while, but it'll set you back a few hundred bucks.

Most of us have traded our desktop systems for laptops, tablets, and mobile devices, meaning there's a lot of outdated hardware sitting in attics. Want to give your old computer a new purpose? Matthew Chappee turned his iMac G4 into an HDTV using the guide by Dremel Junkie.

A faulty or broken thermostat can be one of the most annoying things to ever happen to your house. It's always too hot or too cold, and you can end up wasting money on your electricity bill.

For this project, I decided to rip apart a microwave I found in my neighbor's garbage can to see what was inside. With permission, of course! True story!

Here's a way you can turn a mousetrap into a fun little handgun that shoots up to 40 feet! This is a great project because it can be made with simple materials, very basic tools, and in just a few minutes!

Please visit my Instructable for an introduction to the 555 timer, pinouts, and several applications for the 555 in astable mode: http://www.instructables.com/id/Hack-Your-Snap-Circuits-a-Minimalist-Very-Few-Co/?ALLSTEPS

It's tough out there on the battlefield, especially when your stuck in the trenches and your comrades are dropping like flies. There's no hope. At least, until the next airsoft battle.

Want to learn how to build a robot out of Snap Circuits? I'll show you how to combine Snap Circuits parts from three different sets (the Snap Circuits rover, Snap Circuits Micro, and the Snap Circuits motion detector) to make a simple programmable motion activated robot. For a complete step-by-step build of the robot, visit my project at Instructables: http://www.instructables.com/id/Hack-the-Snap-Circuits-Rover/

It always sounds like a good idea to throw a party... until the party gets there. Next thing you know, you're running around hiding anything breakable, and once everyone leaves, you're stuck cleaning up the mess. But the worst part is footing the bill for everything, and if you don't charge at the door, your chances of getting anyone to chip in are slim to none once the party starts.

Want to learn how to build a laser tripwire and alarm out of snap circuits? I'll show you how to build both circuits— the laser tripwire circuit and the alarm circuit.

Just published my first How-to and the grammar was good, but the layout was...well...bad.

Can anyone please tell me if its possible to transmit audio and video live wireless to my smartphone via my spyglasses? I would like using broadband connection on my smartphone to transmit this data that spyglasses are recording via e.g. Skype to another pc. If my spyglasses have bluetooth function like a handsfree device is there a way to moderate this function so that it can transmit the audio and video from my skype apllication of my smartphone? I would like to create a first person POV game...

If you're the kind of person who misses the bright, sunny days of summer during the colder months, Michail has the perfect addition to your home. He built this "Nuclear Explosion" Chandelier that's as bright as daylight, so you can recreate the feeling of summer, no matter what time of year it is.

You may have never heard of vacuum forming, but you use products made with the technique all the time. The lid on your coffee cup, the plastic bowls you used at last week's barbeque, and the blister packs your prescriptions come in are all made with a vacuum forming machine.

If you haven't met a person that's broken a pair of headphones, you might need to get out more. No matter how expensive or cheap a pair of headphones are, the sound can get buggy, the wire can get cut, or the headphone jack itself can be broken or ripped off the cord. But instead of buying a new set of headphones or borrowing the ones from your cousin with the earwax problem, you can easily fix it yourself.

Do-it-yourselfer Kipkay salvaged parts from an old parallel port scanner and made a flexible, super-bright light in this how-to video. The modification is done by extracting the lamp and running it through clear tubing. He mounted the new lamp above his keyboard for night typing. Watch this video tutorial and learn how to turn an old scanner into a keyboard light.

Getting pulled over sucks, even when you're in a normal car. Just imagine how these teenagers felt when they were pulled over for driving their wooden car without a license! They also got a citation for not having a speedometer or side indicator lights, but if that's all that's keeping their DIY vehicle from being street legal, I'm already impressed.

The mighty Arduino microcontroller can be used to show children how robots work, it can be used to hack into hotel rooms, or it can be used to let you know when you've got a new job opportunity!

Games are always more fun when you have someone to play them with, but if you're not always logged in to your Xbox LIVE account, how do you know when your friends are online? You can always log in and check, but where's the fun in that when you can hack together a traffic light to do it for you?

Who doesn't love Duck Hunt? It's arguably one of the most popular games ever created for the original NES system, even in spite of the mocking dog that everyone hates. I'm sure a lot of people still have their old controllers in the attic somewhere, so unless you're lucky enough to have an NES that still works, why not put that childhood nostalgia to good use?

Want to know when you have a visitor, even if you're not home? You could always set up a security system and live-stream it with your iPhone. But if you don't have a spare iPhone, or just don't want to go to the trouble, this simple hack will add text message alerts to your doorbell so that it lets you know when someone's there.

Stand out from the high street fashion clones with stuff you've fashioned yourself. It's easy to take old pieces of electronic junk and transform them into all sorts of fun 'n' funky geeky accessories. Like a totally useful tote bag, a what-on-earth-is-that wallet and a bedazzling belt. It's terribly geeky but chicy too. Here's how…

Planning on getting the iPhone 5, but want to keep your SIM card? The new nano-SIMs that manufacturers are adopting will be even smaller than the micro-SIMs that most of us currently use. It's fairly easy to cut a regular SIM down to a micro-SIM, but because the nano-SIM will be thinner as well as smaller than the micro, cutting it down to size will require a little more work.

Whether you want to use it to keep your guests safe or just to see who's the most drunk, it's always fun to have your own breathalyzer at a party. We've seen DIY breathalyzers before, like this one by Craig Smith, but how about an Arduino breathalyzer?

If you've got an extra DVD drive laying around not being used, watch this video and learn how to give the lens new life—as a powerful macro lens for your camera phone! You'll be able to take incredible pictures on your camera phone using this clever mod.

Most of us have given up our big, bulky stereos in favor of smaller, sleeker models, but how many of us actually get rid of the old ones? If you don't like the idea of throwing out or giving away electronics you spent good money on, you can always upgrade them instead!

This how-to video shows how you can hack a standard baseball cap into a cool invisible IR mask to hide your face from cameras anywhere, and look perfectly normal to the human eye! You have to admire a technically accomplished hacker. Now don't go out a rob a bank or anything. Watch this video tutorial and learn how to camera-proof your face with a creepy infrared mask.

Create a miniature hover craft from the fan, polystrene or Styrofoam plate, batteries and double-sided scotch tape. It really works. Powered by two 9 volt batteries you can use paper plates for the body of the hovercraft if need be. This is a cool cat toy or just a household hack.

A tachometer, or RPM counter, is a device that measures the speed of something that's rotating. In a car with a manual transmission, the tachometer can be helpful in determining when to release the clutch and how much gas to give when you're taking off. This DIY Arduino Tachometer by Chris on PyroElectro uses an infrared transmitter and receiver break-beam pair to measure the RPM of a computer fan.

Racing games are always better when you have a steering wheel instead of just a handheld controller. And those old-school arcade racing cockpits? Even better. Matthew Boyer decided to bring the feel of a racetrack into his living room with this insanely awesome DIY arcade racing cockpit.

A smartphone is pretty much useless with a dead battery. When you're out and about, it can be hard to find a place to plug in (if you remembered your charger, that is). But this DIY solar panel backpack made by electrical engineer Theodore Protasiewicz will help you use the scorching sun to your advantage and make sure that your gadgets are always ready to go.
