ESR Meter / Transistor Tester Kit
ESR Meter kit is an irreplaceable tool for troubleshooting and repairing electronic equipment by determining performance and health of electrolytic capacitors. Unlike other ESR Meters that only measure ESR value this one measures capacitor's ESR value as well as its capacitance all at the same time. Additionally, ESR Meter also tests and identifies PINs of all transistors such as Bipolar (NPN, PNP), FETs, MOSFETs (N-Channel, P-Channel, enhancement-mode and depletion-mode MOSFETs), Thyristors, SCRs and Triacs. Tests and identifies PINs and voltage of diodes, dual diodes, varicap diodes (and their capacity), zener diodes (test voltage up to 5V) and LEDs. It measures resistance of resistors, power resistors, coils starting from just 0.1Ω up to 20MΩ.
Electrolytic capacitors are by far the electronic parts that suffer aging soonest. If you have any electronic equipment that over the years has degraded its performance, developed quirks, sometimes ending in complete failure, the chances are good that one or more electrolytic capacitors inside it have degraded, causing the problem. Electrolytic capacitors age in several ways: They can become electrically leaky, causing a DC current through them that can make them blow up. They can shift in capacitance value. But the most common way they degrade, by far, is by unduly increasing their equivalent series resistance, which is the undesired internal resistance that appears in series with the wanted capacitance at a given frequency.
     
Specifications:
ESR Measurements: 2.2uF - 20,000uF
ESR Resolution: 0.01Ω - 0.1Ω
Capacitance Measurements: 100pF - 20,000uF
Resistance Measurements: 0.1Ω - 20MΩ

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.

BH1415 Stereo Encoder (parts, no PCB)
This is the latest MPX BH1415 Stereo Encoder that includes a lot of great features in one small package. The heart of Stereo Encoder is a new BH1415 chip from RHOM that includes components that were previously only available in expensive broadcast quality stereo encoders. Connect this stereo encoder to any mono FM transmitter to convert it into Hi-Fi stereo FM transmitter.
Circuit features built-in; crystal oscillator based stereo audio encoding, pre-emphasis for reducing transmission noise, limiter so that the music can be transmitted at the same audio level and 15KHz brickwall low pass filter that blocks any audio signals above 15KHz to prevent any RF interference.
For limited time we include SOIC 28 to DIL adapter free of charge.
Features
================
- Crystal based stereo encoder
- 15KHz brickwall filter
- Audio Limiter
- Pre-emphasis
- Excellent channel separation
