This is design for temperature sensor that is based ATMega 8. LM35 is using for sensing the temperature. This IC is cheaper than the price of this component is also easy to be in the market. This is the figure of the circuit. LM35 have 10mV voltage change per 1 degree centigrade. LM35, in principle, [...]
This is a design for audiometer circuit. This audiometer is an instrument used for the diagnosis threshold of human hearing to give some particular audio frequency and also a certain level of intensity. Raised from the signal generator sinus and selected using a multiplexer 4051. Amplitude or intensity of sound can be arranged through the [...]

Line 6 Digital Wireless Systems XDS-PLUS Pro Power to Go – Metal Chassis Stompbox Digital UHF Wireless. The XDS-PLUS is a rugged digital instrument wireless system sporting many features of the XDR Series packed into a metal chassis stompbox receiver. The result: extended frequency response and extended operating range that only a Line 6 can [...]
This project flashes 18 LEDs at three different rates and you can use these to create a Christmas decoration of your choice. The circuit is kept simple (and cheap!) by using the 4060B IC which is a counter and oscillator (clock) in one package. The circuit requires a 9V supply, such as a PP3 battery. [...]
0-30 VDC STABILIZED POWER SUPPLY Schematic This is a high quality power supply with a continuously variable stabilised output adjustable at any value between 0 and 30VDC. The circuit also incorporates an electronic output current limiter that effectively controls the output current from a few milliamperes (2 mA) to the maximum output of three amperes [...]
