Today we received the question,
“How to control a web cam via internet,
i want to use it for security reasons, always out of the house and my PC connected want to open the cam from time to time to checkout if something wrong!!”
– [Mohamed Saleh]
What a fun project we thought! And so many different ways of tackling it. Find out what we suggested to [Mohamed] after the break. Continue reading “Ask HackADay: Network Security Camera”

Reader [Eric] sent us a powerfully informative, yet super simple hack for the MindFlex toy. Don’t worry, it’s not another worthless shock ‘game’, And it’s using an actual interface instead of the built-in LEDs.
With two wires for the serial protocol, and an Arduino, you’ll be able to view “signal strength, attention, meditation, delta, theta, low alpha, high alpha, low beta, high beta, low gamma, high gamma” brainwaves. While it’s not medical grade, it’s a lot more intuitive than previous interfaces.
The original intent was for a system called MentalBlock, but we’re wondering what would you do with brainwave data?
Here is something we didn’t expect (NSFW). The machinima crew behind RedVsBlue, Rooster Teeth, actually did a hack!
The idea is simple enough, how could you experience driving a vehicle like in a video game – aka, third-person. With some steel bar, Canon 5D camera, and a 15inch monitor inside of a blacked out cab, they accomplished just that.
What surprised us the most, is the great difficulty and difference there is between the video game vehicle and the real life one. But all of us here at HAD know why; they need to replace the steering wheel with a joystick. While they’re at it they can make it wireless and remote-controlled. Finally a HUD would be easy enough to program (might we suggest processing). Oh dear lord, is the world ready for this!?
Its been quite a while since we’ve featured something from iFixit. But when we saw they had torn apart the next greatest Apple product, the iPad – released today, and how everyone on our team loves it, we thought why not also let our user base enjoy the destruction informative teardown as well.
In both the original and the FCC teardown, we see some awesome features and tricks Apple implemented. Most notably the two separate 3.75V lithium polymer cells, not soldered to the motherboard, allowing users to easily replace the battery if need be. However, in the opposite respect, more components than ever are being epoxied to the board, making the iPad much more rugged.
We’re left wondering, with everyone able to see the beautiful insides, does it change anyone’s mind on getting an iPad? Or would you rather make your own?
It’s inevitable. You knew it, we knew it, and while this is being posted on April 1st; its no joke. [johndavid400’s] Core3Duino. As we mentioned before, with the additional Arduinos you have now 3 separate processors, allowing 24digital IO, 18 PWM, 18 analog inputs, and more.
Now to keep flamers at bay (calm down), we’ve combined this post with the introduction of xDuino. Yet another attempt at porting Arduino to separate hardware platforms. For the price of a Duemilanove you can have 5 serial, 48 IO, 18 analog, 68Kbytes of Ram and more!

What weighs 120 pounds, can fly at you near 20mph, score soccer balls, climb 90inch tall towers and more all while remotely controlled? If you said a robot from this years FIRST, For Inspiration and Recognition of Science and Technology, competition congrats you’ve won one internet.
This past Thursday, Friday, and Saturday (March 25-27 respectively) the Oklahoma FIRST regional competition took place. Once again I, HaD writer [Jakob] was lucky enough to not only attend, but compete! Check out our full breakdown after the jump. Continue reading “(the) FIRST Robotics Competition”
…and wins. Well, 3rd in class, but still surprisingly well for such a cheap entry. This is truly a show that with enough elbow grease and headlight fluid anything can be accomplished money just makes it a ton easier.
Everything from the roll cage to the 5 minute gas tank fix was fabricated by [Bill Caswell]. Well — fabricated is a rough term for duct tape at that point, but this is still an awe-inspiring and truly motivational story for any hacker and car enthusiast alike.
