Face on a graphics Display

Face on a graphics Display The code runs at a clock frequency of 8 MHz. The controller is programmed using STK500 in ISP programming mode. void check(void) { TIFR0 = 1<<TOV0; TCNT0 = 255-125; TCCR0B = 1<<CS00|1<<CS01; count = 0; freq = 0; stop_check=0; while(count<200) { while((PINA&(1<<4))&&(stop_check==0)) while((!(PINA&(1<<4)))&&(stop_check==0)) if(PINA&(1<<4)) { freq++; } } freq...

Valentine’s Heart LED Display with Proximity Sensor

    To use the touch-sensitive throbbing heart, just hold the circuit board by your chest (put the batteries in the adjoining pocket) and turn it on. The LEDs should start blinking at a normal rate. Now bring a hand close to the blinking LEDs, and the throbbing rate should start increasing. Keep bringing the hand closer to the circuit board and eventually touch the board and then take your hand away. Once you take your hand away, the...

Spinning LED Top with Message Display

               Once the top is soldered, the batteries are installed and the microcontroller is programmed with the application code available from our website, using the ISP interface. Once the microcontroller is programmed, the ISP cable is removed and the power switch is turned on. Gently hold the axle of the top between the palms, spin the top, and let it go on a solid flat surface. You will see messages...

Batteryless Persistence- of-Vision Toy

Design a batteryless POV toy that is programmed with text and graphics patterns in a microcontroller. The toy uses seven LEDs arranged in a column, which is waved through the air. These LEDs are controlled by the microcontroller, which generates a pattern of light on the LEDs that an external observer sees as a message or graphics due to the persistence of vision. The operating power for the toy is derived from the Faraday generator. //Make: H const...

Batteryless Infrared Remote

To use the batteryless TV remote is as simple as 1-2-3. Just shake the remote a few times and press the desired key! Circuit Inside the Remote TV Remote          The main section of the microcontroller executes a tight loop waiting for a key to be pressed. Until a key press occurs, the microcontroller goes into sleep mode to conserve power. A key press causes a pin change interrupt, which wakes up the...

Microsoft Windows shmedia.dll Division By Zero, Explore.exe DOS Exploit

The shmedia.dll module, serves as shell media extension for Windows, which provides statistics and thumbnails for media files. The dll has also got the ability to acts as media file property extractor of the Windows shell(explorer.exe) to extract custom attribute information from audio, video, midi, and video thumbnail files including MPEG, MPE, MPG, ASF, ASX, AVI, and WMV.  The shmedia.dll application calculates the bit-rate of the file and creates a thumbnail preview for the Properties. So when a user open a folder containing AVI,MPEG file...

Mobile Hacking

Hey Guys tomorrow I have an exam of Wireless Communication,I am just reading a book of it and I just think about this technique which I am sharing here... When 1G or AMPS network invited, it has so many vulnerabilities like eavesdropping and handset cloning because it was work on analog domain. But 2G network works on digital and uses different sort of encryption algorithm to protect the data. Here I am going to give you some brief idea about...

To Improve FireFox Speed

Firefox is already pretty damn fast but did you know that you can tweak it and improve the speed even more? That's the beauty of this program being open source. Here's what you do: In the URL bar, type “about:config” and press enter. This will bring up the configuration “menu” where you can change the parameters of Firefox. Note that these are what I've found to really speed up my Firefox significantly - and these settings seem to be common among everybody else as well. But these settings are optimized for broadband connections - I mean with...
