Internet is one of the major needs of this contemporary world. Almost every work can be done on the web and people love doing things on the web because it is time and cost efficient. It is just one of the greatest blessings of technology.
However, there are lots of web sites, which are not safe because your personal info can be hijacked through them. Therefore, in order to save your personal information you should use a proxy. But do you have the right knowledge of how to use a proxy?
Using a proxy server to surf online safely is…

Pulse Width Modulation is a topic that tends to give a lot of beginners trouble. [Daqq], whose nixie plasma ball we covered a few days ago, has a simple but effective PWM project that you should take a look at. The circuit used 9 LEDs clustered together into 3 sets of RGB modules and connected them to an AVR ATtiny2313 through some current limiting resistors. Most of the time the PWM function of the AVR’s timers would be used to generate the signal but this application calls for 9 signals which is more than can be produced by this…

Full Spectrum Engineering has offered up a tutorial for their inkjet direct PCB kits that repurpose direct-to-CD capable inkjet printers (such as the Epson R280) to print etch-resistant ink straight onto copper clad board. This is easier and less error prone than some iron-on methods, especially for two-sided boards. Just print (no need to reverse the design), dry on a hot plate or in a toaster oven for a couple minutes, and your board’s ready for etching!
Homebrew methods exist for all of this, but for those who would rather move ahead with their design than spend time scrounging for the required bits, the…

In November, we covered installing Boxee on AppleTV using atv-usb-creator. [Danny] has written a tutorial on installing Boxee, XBMC, NitoTV, SSH access, and external USB hard drive support. His method installs most of the software via the USB patch stick, then uses the SSH support to enable the external drive and install NitoTV. The tutorial lists a Mac running OSX 10.4 or newer as a prerequisite but there is now a Windows version of atv-usb-creator. According to their Google Code page Linux support for this package is on the way.

[Mike] sent in this project he’s been working on. He has posted instructions on how to get your Palm Pre to tweet its GPS coordinates at regular intervals. It does require that you have Linux installed on your Pre, but that’s not that big of an issue as he has a tutorial for that too. Getting the tweet to happen involves setting up a custom PHP file that sends the tweet, then a cron job to get it to run on a schedule. He mentions this could be use full for finding a lost phone as well as keeping…

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sensors can be put to other uses—cat flaps, camera triggers and purely artistic applications—as you’ll see in several demo projects and videos. For the curious, the tutorial provides a good amount of background theory on how PIR sensors work, along with the associated fresnel lens optics. And for those who just want to get hacking, most PIR sensors (like the one above) come in a simple-to-interface module containing all the support hardware and providing a simple digital…

Twitter is a simple and yet famous social networking website, recently I wrote a post about some basic habits every blogger should adopt. Reading that post, one of our readers asked us to share the secret to get hundreds of followers on Twitter. Well, Chankya told ‘ Never ever share your secrets with anybody, it will destroy you ‘. I do not care what Chankya said, I only care about my readers and I love to share my thoughts with them. So here is trick that will help you in getting hundreds of followers.Requirements : * A Twitter account…

It might be a little bit of overkill, but this etching container agitator sure looks convenient. There’s not much to it technically, a small circuit with an ATtiny45. For those beginning with this stuff, he has written a pretty good tutorial on working with basic microcontrollers. If you are more interested in a tutorial on etching, we did a  guide on how to etch a single sided PCB.
