Voltmeter Ammeter Kit - Blue Backlight LCD
Voltmeter Ammeter can measure voltage 0-70V or 0-500V with 100mV resolution and current consumption 0-10A or more with 10mA resolution. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored. The meter uses PIC16F876A microcontroller with built-in ADC (Analog to Digital Converter) and 16 x 2 LCD display with blue backlight. With slight modification it is possible to measure higher voltage and current.
View Schematic
To measure voltage that is higher than 70 Volts simply replace R3 6.8K resistor with included 1K resistor. This will allow to measure up to 500 Volts.
To measure current that is higher than 10A simply replace 0.47 Ohm 5W power resistor with higher wattage or lower resistance resistor. For example 0.1 Ohm 10W resistor will allow to measure up to 20 Amps.

4-Channel 433MHz Wireless RF Remote Control Kit (200m)
Having the ability to control various appliances inside or outside of your house wirelessly is a huge convenience, and can make your life much easier and fun. RF remote control provides long range of up to 200m / 650ft and can find many uses for controlling different devices, and it works even through the walls. You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.
Four button RF remote is used to turn ON / OFF four different devices independently. Any of the four outputs can be configured to work independently in either toggle or momentary mode. Outputs are buffered by BC549 NPN transistors and can drive low voltage devices directly or be connected to 5V / 12V / 24V relays to control appliances that use 110V / 220V mains voltage or any voltage of your choice.
Multiple remote systems can be used independently to control more than four appliances in the same location by changing the address code on 433MHz receiver and remote. It is also possible to use several remotes to control the same appliance such as garage door.

DS18S20 Dual Temperature Meter Kit - Blue Backlight LCD
This package includes all components including PCB that are needed to build DS18S20 Dual Temperature Meter Kit with 16 x 2 LCD display with blue backlight 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 retains selected mode even after power is disconnected.

TDA7000 FM Receiver (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.
