Learn to build custom speakers by installing bare speakers in two of the
original iPods where the scroll wheels normally are. Instead of
gutting your old iPod, you can purchase iPod front panels and back panels on eBay for a few bucks. Just add a simple amplification circuit and you’ve got yourself a pair of custom iPod speakers.
Use a bluetooth adapter
and some free software to read data from your wiimote’s accelerometer
and sensors. There are fantastic connectivity tutorials here and here
using software is avaliable for Mac, PC, and Linux. Why would you
want to do this you ask? Pairing your PC and Wiimote enables you to
develop fantastic wiimote projects such as:
Ever wonder what you should do with your old hard drives? Turn them into
speakers! It’s fairly easy, all you need is some hard drives (the more,
the better), some soldering tools, some headphone wire, and an audio
source (iPod, Computer, etc..). For more info on the project, check out
the project details. A similar project can be found here.
A major problem with video chat is people cannot have a conversation
while retaining eye contact. Since eye contact is an essential part
of any communication from casual chats to business calls, this simple
solution may be able to help. Although the device is a bit bulky, it
easily slides off when you’re done chatting.
Using mirrors, the image is “projected” directly in front of the laptop camera, providing the illusion you’re looking the person directly in the eye. Essentially it’s the same thing as a modern teleprompter, the device commonly used by today’s news anchors.

It’s quite common to have a timed lockout after entering several bad passwords. This simple form of security makes automated brute force attacks unfeasible by ballooning the time it would take to try every possible permutation. The lock screen on iOS devices like iPad and iPhone have this built in. Enter your code incorrectly several times and the system will make you wait 1, 5, 15, and 60 minutes between entries as you keep inputting the wrong code. But there is an exploit that gets around this. [Pierre Dandumont] is showing off his hardware-based iPad lock screen attack in the image above.
He was inspired to try this out after reading about some Mac EFI attacks using the Teensy 3. That approach used the microcontroller to spoof a keyboard to try every PIN combination possible. By using the camera kit for iPad [Pierre] was able to do the same. This technique lets you connect wired keyboards to the iPad, but apparently not the iPhone. A bluetooth keyboard can also be used. These external keyboards get around the timing lockout associated with the virtual lockscreen keyboard.
We’re of the opinion that this is indeed a security vulnerability. If you forget your passcode you can simply restore the device to remove it. That wipes all of your personal data which can then be loaded from an iTunes backup. Lockscreens are paramount if a device is stolen. They will give you the time you need to change any online credentials which might be remembered by the device.

When was the last time you backed up your important files? Last year when your friend called in tears after the Blue Screen of Death ate his thesis? We thought so. Learn to set up a program called SyncBack which automatically generates password protected zip files of your important documents.
Benefits:
- It’s free and pretty easy to use.
- You can choose to save them to an external hard drive or upload them to an FTP server.
- Schedule nightly, weekly, and monthly backups so you don’t have to lift a finger.

A team of researchers from Georgia Tech unveiled their findings yesterday at the Blackhat conference. Their topic is a power charger exploit that installs malware on iOS devices. Who would have thought that there’d be a security hole associated with the charging port on a device? Oh wait, after seeing hotel room locks exploited through their power jack this is an avenue that should be examined with all device security.
The demonstration used a charger and an BeagleBoard. Plugging in the charger is not enough to trigger the exploit, the user must unlock the screen while charging for it to go into action. But once that’s done the game is over. Their demo removes the Facebook app and replaces it with an infected impostor while leaving the icon in the same place on your home screen. They notified Apple of their findings and a patch will roll out with iOS7. So when would you plug your device into an untrusted charger? Their research includes a photo from an airport where an iPad is connected to the USB port of a public charging station.
The summary on the Blackhat site has download icons for the white paper and presentation slides. At the time of writing we had a hard time getting them to download but succeeded after several tries.

Some files are just too large for emails even in this age of broadband. But the bottleneck is in the storage space needed to transport huge files from the sender to the recipient in a secure channel especially when server space is at a premium.
Most email services don’t allow large attachments – Gmail’s limit is 20MB. Thankfully, this need has been filled by some online file delivery services that allow us to transfer massive files over the internet for free.
Though there are definitely more than ten online file delivery services, these are the top free file transfer services.
Top 10 Ranked by File Size Limits
YouSendIt LiteYouSendIt lets you send files as large as 100MB with a 1GB monthly download limit. Sign-up is not required and it is supported by advertising that appears on the upload and download pages. The recipient gets an email message with a link showing where to get the file. Maximum number of downloads allowed per file is 100 and the recipient has up to 7 days to pick up the file. The Lite version is stripped down and lacks some of the more advanced features like security and tracking. For simple file transfers, this is a capable solution.
GigaSize
GigaSize offers two free ways to send your large files – Without a log-in (Free Center) lets you upload a max of 300MB with a 10 file cap. A registered Free Account on the other hand allows for 300 MB/file but unlimited uploads. Plus, your files are kept for 45 days. An account also gives you the flexibility to organize your files using a file organizer. You can also import your Yahoo, Hotmail, MSN and Gmail contact list and share your file with friends by sending those links to the file.
The free accounts are ad-supported, have waiting time for downloads and have slower speeds than a premium account but hey, it’s a free lunch.
Send Space Lite
Send 300MB files to any email address you want with this file transfer service. You can upload 5 files in one go though the daily bandwidth restriction is 1GB. There are no limits on the number of downloads. Inactive files get automatically deleted from the server after 7 days. Though you don’t need to register, a log-in name opens up additional file management features. Upload and downloads are eased by a SendSpace Wizard tool.
Spread It
Spread It is another in the line of simple, utilitarian file sending services which send your files without requiring a log-in. Spread-It will automatically email you a link to your file stored and another to delete it. A file can be up to 500MB and is kept online for 14 days, without downloads limit or waiting times.
zUpload
With zUpload you can send across a maximum of 500MB per file in a jiffy but you can upload as many files as you want. With each file you get a unique URL which you can mail across to others for unlimited downloads. Your file stays available for 30 days. The web service is supported by ad revenues and donations.
MegaUpload
MegaUpload has an ad-financed free online storage service and a premium service with additional features and light advertising. Free membership requires a log-in and gets you 200 GB online storage with a file manager. After an upload, you can share you link with others. You can download a maximum of 1GB per session.
Particularly useful is the support for resuming broken downloads and uploads and the use of download managers. There are no restrictions to the number of downloads. Also a frequent user can earn reward points from downloads and encash it for a premium service.
A few disappointing features take some sheen away from the free service – a waiting time before downloads begin, capped download speeds and download slot unavailability for some countries.
Transfer Big Files
Transfer Big Files (beta) is again one of those simple no frills services. It lets you send 1GB sized files in one go. Files are kept for 5 days prior to deletion. There is no storage limit so you can send as many files as you want. To send the files you do not need to register. For quick use, the designers have also created a Windows System Tray tool that allows users to drag-and-drop files to the site.
Filemail
Filemail helps you send up to 2GB files to others through your browser. Upload your bulk to FileMail, enter the recipient(s) email ID and send. The recipient receives an email from FileMail with the links for download. After a user specified number of days or downloads, the files are removed completely from the servers. FileMail is clean cut, secure and utilitarian – no registration is required and so far it is ad-free. FileMail is also available in 14 languages.
File Dropper
Elegant with an uncluttered Web2.0 interface is how I would describe it and with a 5GB upload limit it is weighty too. Sending a file is dead simple – upload and share your personal link. It does just one job and does it well.
MegaShares
An upload limit of 10GB per session is more than enough to send even the Harry Potter series through the mail. With MegaShares you can send a single file or multiple files. A Java based browser tool lets you drag and drop files for easy uploads. After it’s done, you will get a URL that you can email to your friends or keep for yourself. A selected option can send the link automatically to any provided recipient email.
Megashares also support most download managers. Uploads are completely anonymous and every uploaded document is encrypted unless the file is made public. Any file remains available as long as there is 1 unique download in 15 days and 10 unique downloads in 45 days through your unique link.
What do you think, did we miss any? If you think we missed some of the best services, let us know in your comments!
We’ve seen a few odd ways to transfer data before (see sound transfer over lasers)
but this is probably the most bizarre. Instead of using a USB drive,
this man decided to invent his own file transfer method by using his
sound card to send morse code-like messages representing 1′s and 0′s.Â
This guy definitely deserves some geek street cred for coming up with
this.
How it works:
How it works:- For every character:
- For every bit:
- Send a short pulse if the bit is 1.
- Send a long pulse if the bit is 0.
- Send a silence.
- Send a very long pulse (4 times as long as the shortest pulse).
- Send a silence.
Yes, you’re probably drooling at the above picture too. What an absolutely incredible setup! There are actually several computers hooked up to the monitors and they can be controlled by the single mouse and keyboard using Teleport. Check out the entire flickr set and sleek slideshow for more details on the setup and a description of all the gadgets shown. (scroll down for more pics and info)

Odds are you have spare hard drives lying around from old computers.
Instead of tossing them out or letting them collect dust, you can easily turn them into DIY external hard drives and use them to backup your important files. Basically all you have to do is pick up a cheap hard drive enclosure, stuff the old drive inside, and connect it to your computer.

If anything can go wrong, it will. This means although it can be a bit tedious, we always need to backup our computers. Data backup is not only good practice; it’s an essential one. It may be a spanking new computer or a jalopy for the digital world, data backup is as important as a virus scan or keeping a firewall.
Think of all the files accumulated over the years. One snafu and oops it’s gone. Good news is that data backup solutions can fill that gap for you. It’s out there’s easy and importantly, it’s free. One of the backup solutions is built right into your operating system, some of it is on the web and some can be provided by a kind friend.
Manual backups are like heavy duty lifting. Backup utilities like IdleBackup (Windows) and SilverKeeper (Mac OS X) automatically sync folders for you, relieving a lot of the work load.
Here are a few in the queue:
- Docs: For your documents, why go any further than the trio of Google Docs, Office Live and Zoho.
- Pics: For your photos, make your online accounts with Flickr, Snapfish, Picasa, Photobucket or Facebook.
The Basics:
The easiest and most accessible backup is obviously on another networked computer. Simple file sharing between two computers makes it a routine of copy and paste. Configuration is slightly different among the different systems (Windows XP, Windows Vista and Windows 7). Native Mac backups or with a PC are also pretty much covered.Manual backups are like heavy duty lifting. Backup utilities like IdleBackup (Windows) and SilverKeeper (Mac OS X) automatically sync folders for you, relieving a lot of the work load.
1. Simple File Storage Sites
Cloud computing is upon us and so why not take a look at some online solutions. Of course, you can go for full system backups which are available at a premium. But we did mention “free” in the title. A lot of online file storage companies offer ample space for free though falling short of complete system backups. Backing up your stuff online thus calls for cherry-picking essential files and safekeeping them online.Here are a few in the queue:
- Windows Live Skydrive: A total of 25GB for free with a per file size limit of 50MB.
- File Factory: 100GB of free storage with a 300MB file limit. Downer could be the slow speeds.
- Dropbox: For smaller needs. Offers 2GB of free storage with neat file syncing features.
- Mozy: 2GB of free storage but with a handy Windows client that makes uploading a cinch.
- Orbit Files: 6GB but with limited choices.
2. Documents, Photos, Music and Videos
Yes, some of these websites do double over for file storage needs. You probably use them every day but never looked at them from this angle.- Docs: For your documents, why go any further than the trio of Google Docs, Office Live and Zoho.
- Pics: For your photos, make your online accounts with Flickr, Snapfish, Picasa, Photobucket or Facebook.
- Tunes: For music, MP3Tunes, File Factory and Deezer sound really cool.

Sparky Jr is a homebuilt robot from basic hardware and leftover materials that acts as a mobile video telepresence robot. It has a forward mounted screen and webcam so you can chat as well as WiFi and computer hardware to enable the communication.
The hardware needed to build Sparky Jr is pretty straight forward. An old Mac computer, 7†VGA screen, communication hardware such as the webcam, and a roomba vacuum cleaner.  Sparky can be driven with WASD from a computer keyboard or it can be programmed to respond to a video game controller. All of the software and instructions needed to build Sparky Jr. are included in the guide and can be downloaded to your computer.
The site itself covers the hobby of creating Sparkies around the world. The homepage is full of conferences, demonstrations and conventions where people show off their Sparky creations. Many heavily mod the original and come up with something truly unique like the ones above. You can ‘add a blog post’ to the homepage yourself to post pictures of your Sparky and describe how you built it. There is also a discussion forum.
