Instructables member Dimovi shares a wonderful hack where you can turn your old LCD monitor into a privacy monitor! The crazy thing with this privacy monitor is that it looks all white to everybody except you, because you are wearing “magic” glasses! People might think you are crazy, staring at a blank white screen wearing sunglasses! But I guess that makes it even more fun! Materials required for this build are:
You can refer the step-by-step procedure of making this project here.

Have you ever heard of a walking machine made from bent wires and run by a single 1.5V AA battery wherein the motor and battery can rotate with crank? Hackolog member brought this amazing concept, where you can build your own walking machine just by using fewer components. You can start by connecting the motor to the crank to which the wheels are fitted. Now when the wheels meet an obstruction the motor starts driving the crank round, the spinning eccentric weight of the motor causes the robot to jump up and down and the foot oscillates. To get an idea how the machine looks like, you can refer to the pic below:

If you want to drive the guys over at Open Picus nuts send a tweet to their dancing santa! Check out their Open Picus Dancing Twitter Santa project to see how they connected the santa with a few bits of electronics to their system. I have a feeling that this will be a fun gadget on the desk until it keeps dancing non stop for a few hours… “I have a Santa Claus that lights up and moves when you turn on its switch. So bypassing the switch, you can build a virtual switch with an NPN transistor. The base is controlled by the signal coming from the “out2″ of Flyport with a resistor to limit the base current. Our Santa Claus, it’s like an active load between the collector and VDD (2 AA batteries) and the emitter to ground (GND) shared by Flyport and Santa Claus.”

Makezine in its blog reported that Yoonjo Choi has modernized her old typewriter by adding force sensors and monitor connectivity, so that her old photographs can now be flipped quickly through projection. The way in which her old photo displays on the monitor possesses a magical effect. The project draws attention to the photos in a way that a digital slideshow or picture frame cannot. The most amazing feature is that you can only see the photo when you type at a certain rate. For example, if you type less than five letters within ten seconds you will only get a vague outline of the photo. If you type more than five and less than ten letters it gets a bit more crisp, and so forth. Watch out this video to know more about this hacked Typewriter:

Our friend Viktor sent in his latest build. He took a $1.99 IKEA plastic bag dispenser which looks great for only a few dollars and used it as the structure of his DIY moodlight. I visited my first IKEA last year and was quite amazed at how they create an experience that I have never had in any other store. I had to hold back from purchasing a ton of odds and ends for future projects since I haven’t finished the huge pile of projects on my list. An IKEA will be opening on a year or two in Winnipeg and I am thinking it will be a frequent stop for cheap project material and inspiration. “At the heart of the circuit is one of the smallest PICs, a PIC12F683, which has only 8 pins. It only has one PWM channel but I needed 3 channels for the three colours, so I had to implement 3 channels of PWM in software. The plastic bag dispenser from IKEA is a perfect fit for this purpose: it has a solid frame that is easy enough to customize using some not too powerfull power tools, white in colour, it already has mounting points on the back for easy hanging on the wall and the frame has large holes on it so that cables and the white fabric I got for it to cover can pass through them easily.”

Thanks to Ben from NBitWonder for sharing his Software-Defined Radio project with us. “There is much more work to be done on the software, as you can tell from watching the video. For instance, only AM reception is implemented right now. The signal processing functions still need some work, and more appropriate gains should be chosen for the entire signal chain. Still, it is rewarding and reassuring to see the project working at some level.” |

We have seen single color LED detection before, fjordcarver has built a DIY Color Detection using an RGB LED that can detect the actual color of the object placed in front of the home made sensor. “For this sensor you will need
