DS18S20 PIC Dual Temperature Meter Kit
This package includes all components including PCB that are needed to build PIC Temperature meter with 2x 16 backlighted LCD display and two DS18S20 digital temperature sensors. Meter can display both Celsius and Fahrenheit values (together or individually) and is capable of measuring temperatures from -55 to 127 degrees Celsius (-67 to 260 degrees Fahrenheit). An excellent feature of this temperature meter is that it can measure temperatures remotely. DS18S20 sensors can be placed many meters away from the main circuit because they send the temperature readings as data, just over a two wire cable. DS18S20 sensors require no calibration at all, which means that all temperature readings are 100% accurate out of the box. PIC Dual Temperature Meter includes 6 display modes for arranging temperature information on LCD display to your own preference. Simply press and hold Display Mode tactile button for one second to switch to the next display mode. Display mode is automatically saved in non-volatile EEPROM memory so meter will remember selected mode even after the power supply is disconnected.
Specifications
Voltage Supply: 7.5V - 15V
Power Consumption: ~ 10mA with LCD backlight / ~ 3mA without LCD backlight
Display Modes: 6 - For arranging temperature information on LCD display to your own
preference. Modes can be set to append numbers "1:", "2:" & "Out:", "In:" labels so it is easier to identify connected DS1820 temperature sensors.

TDA7000 FM Receiver (Project Parts)
This simple one chip FM receiver / TV tuner will allow you to receive frequencies from 70 up to 120MHz. With this small receiver it is possible to pick up TV stations, entire 88 - 108MHz FM band, aircraft conversation and many other private transmissions. It is a perfect companion to any FM Transmitter especially if FM band in your area is very crowded. TDA7000 receiver offers very good sensitivity therefore it will even allow you to pickup weaker signals that cannot be heard on conventional FM receivers. A neat feature of presented TDA7000 FM receiver is a voltage controlled oscillator similar to TV tuners that are used in television sets. Frequency is tuned by varying the input voltage to the oscillator. The advantage of this type of oscillator is that you can use regular 100K potentiometer to precisely tune to a given broadcast. Tuning can be performed much quicker and precisely than by using a trimmer (variable capacitor). Trimmers will also shift the frequency as you touch them where potentiometer will not. Trimmer also needs to be placed on receiver's PCB to minimize the stray capacitance where potentiometer can be conveniently placed anywhere you want because it will not be affected by any external capacitance.
