This looks like a really interesting, and fairly easy, project to build.But,the system is NOT a radio astronomy system to be used for serious sky surveys, but it is a tremendous starter unit to give you the excitement of detecting the Sun, your own body radiation or just 300 deg. K tree branches.Main equipment needed: a DirectTV 18-inch satellite dish with LNB and mounts,one Channel Master 1004IF[more]

This heartbeat controlled MIDI project design by Recotana who is the meber on MAKE Flickr pool ,This project consist of microcontroller PIC12F675, IR photo sensor,opamp,very small midi controller detect a heartbeat, and MIDI send.it very cool! Interesting choice in sound patch for the demo video - emphasizes that man/machine contrast. Now we just need one more clip documenting a heart-pounding treadmill recording session.[more]

This project consist of two main part :The IR receiver:When the TSOP1736 (IR receiver) receives an infrared (IR) signal from a RC5 or RC6 remote control (like Philips) burns LED1 (green).The LCD shows when it receives a new type of code for one second which protocol is received (RC5, RC5X or RC6).After then the LCD shows the RC5 or RC6 system- and command code in decimal as wel in binair.The IR transmitter:With the IR-transmitter it is possible to send every possible code from the RC5, RC5X and RC6 protocol, like a remote control does.With the help of the LCD you can adjust which RC5, RC5X or RC6 system- and command code must send out.This project control with PIC16F628.[more]

This project describes a very powerful frequency counter. Very simple construction which everyone can build. 6 LED display will present the frequency with 1kHz resolution and
RS232 communication to computer is available as option. The software has also been implemented with some smart functions, for calculating frequencies in receivers where IF is 455kHz or 10.7MHz. [more]

If you like PC modding this is cool project for you.this is an USB interface for alphanumeric LCD display like 4×20 which can be controlled with LCDSmartie program.USB interface is implemented by using PIC18F2550 microcontroller. Using USB LCD module you can view many types of information taken from PC like temperatures, time/date, MP3 song titles, view emails, RSS feeds – all that LCDSmartie or other program supports.[more]
