Do you know that we should feel glad to live in this 21st century, where our daily life becoming much easier than few centuries ago? Thanks to the advancement of technology, we’re now about to entering into the “SixthSense” world…
The SixthSense is a wearable gestural interface, and it displays the physical world around us with digital information and allows the users to use natural hand gestures to interact with all those information.

Most of us were born with our five natural senses and we have been taught to use them since childhood. We use our five natural senses to perceive information and make the right decision.
SixthSense is a new breakthrough in the technology field, where is bringing intangible, digital information out into the tangible world. The more interesting part is it enables the users to interact with all those useful information via natural hand gestures.

The amplifiers are too small for you? Would you like to have some extraordinary amplifiers? Nah, it’s not only extraordinary, but all of them are super huge Class-A Amplifiers! You don’t believe about it? Then, you can have a look on the below figure…
What you’ve saw here is the real project, where it use the super Class-A 30W amplifiers as the main point. For your information, you can build this gigantic project by using Toshiba 2SA1943 and 2SC5200 complimentary transistor pairs, where they have more robust output stage. The 2SC5200 is being used, as it allows the user to increase the rail voltage and let the amplifier to deliver even more power.
This Super Class-A Amplifier is fully running at a bias of about 1.65A @ 35V, which it resulting in about 58W of continuous dissipation per transistor in the output stage. In this condition, you can highly imagine that the [...] [Via]

You love toast breads, but you would prefer the toast breads with some incredible “tattoo” in the middle of it? Well, you wish is granted with this awesome “VHS Video Toaster“!
To be honest, the inspiration for this project is coming from “The Young Ones”, one of the BBC TV’s comedies. You don’t have to overestimate this project, as it’s as simple as ABC. All you need to do is to convert a VHS video into a toaster, and then you can easily eject it through the cassette slot.

Although the development of this project is quite easy, but you shouldn’t careless, as you’re dealing with the electrical appliances. There are few things that you must pay attention here:
You have to ensure that the metal parts are already earthed;
Remember never place it on heat-sensitive surfaces or on any sensitive materials that can cause unpredictable explosion;
Please don’t touch any hot surfaces, as [...] [Via]

I have done a simple infrared remote control receiver with RS232 ascii output. It can be used for developing remote controls on a PC using the serial port. In practice, the infrared bursts are converted in ascii characters and sent to the RS232 port. The downloadable ZIP file contains the schematic diagram, the printed circuit board, the components disposition and the object file to write into the ATMEL ATtiny2313 microcontroller.
