ESR Meter / Transistor Tester / LC Meter Kit - Blue Backlight LCD
ESR Meter / Transistor Tester / LC Meter kit is an amazing auto-ranging multimeter that automatically identifies and analyzes components being tested. It measures ESR values, capacitance (100pF - 20,000uF), inductance (10uH - 20H), resistance (0.1 Ohm - 20 MOhm), tests many different types of transistors such as NPN, PNP, FETs, MOSFETs, Thyristors, SCRs, Triacs and many types of diodes. It also analyzes transistor's characteristics such as voltage and gain. It 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.
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: 0.01 Ohm
Capacitance Measurements: 100pF - 20,000uF

ESR Meter / Transistor Tester / LC Meter Kit
ESR Meter / Transistor Tester / LC Meter kit is an amazing auto-ranging multimeter that automatically identifies and analyzes components being tested. It measures ESR values, capacitance (100pF - 20,000uF), inductance (10uH - 20H), resistance (0.1 Ohm - 20 MOhm), tests many different types of transistors such as NPN, PNP, FETs, MOSFETs, Thyristors, SCRs, Triacs and many types of diodes. It also analyzes transistor's characteristics such as voltage and gain. It 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.
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.

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.

EasyDriver Stepper Motor Driver
The EasyDriver is a simple to use bipolar stepper motor driver that supports microstepping. It can be used to control 3-axis CNCs, robots, home appliances, etc. It's compatible with any source that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder 3/5V pads). Board is powered by 7V to 30V supply to power stepper motors with any voltage. It has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got a precision motor control. EasyDriver drives bipolar motors, and motors wired as bipolar. I.e. 4, 6, or 8 wire stepper motors.
This is the newest version of EasyDriver V4.4. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.
Note: Do not connect or disconnect a motor while the driver is energized. This may cause permanent damage to the A3967 IC.
Features
A3967 Precision Microstepping Driver
MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)
Compatible with 4, 6, and 8 wire bipolar stepper motors such as popular NEMA 17
Adjustable current control from 150mA/phase to 750mA/phase
Compatible with Arduino GRBL G-code interpreter for driving 3-axis CNC machines

The ESP8266 WiFi Module is a self contained SOC with integrated TCP/IP protocol stack that can give any microcontroller access to WiFi network. The ESP8266 is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. Each ESP8266 module comes pre-programmed with an AT command set firmware, one can simply hook this up to your Arduino device and get about as much WiFi-ability as a WiFi Shield offers. This module has a powerful enough on-board processing and storage capability that allows it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, including the front-end module, is designed to occupy minimal PCB area. The ESP8266 supports APSD for VoIP applications and Bluetooth co-existance interfaces, it contains a self-calibrated RF allowing it to work under all operating conditions, and requires no external RF parts.

470uF / 35V ELNA SILMIC II Audio Capacitor
The SILMIC II series are Elna's highest grade audio aluminum electrolytic capacitors that exhibit superior acoustic characteristics. An entirely new type of electrolytic separating paper is used, containing silk fibers. The extreme softness of silk can mitigate vibrational energy (generated by the electrodes, by external vibrations and by electromagnetic fields). Due to it's new electrolytic and foil design the signal propagation speed has increased (the ESR is reduced) and a more powerful, yet-mellow, sound is possible than before. When these capacitors were subjected to aural evaluations, the high range peak and midrange roughness were reduced substantially. Also, the low range richness and power were increased in the obtained high-quality sound.
Features
SIMIC II Highest Grade Audio capacitor
Uses Silk Fibers
Low ESR
Oxygen-free Copper Lead Wires (provide extremely low distortion)
Excellent for Power Amplifier / SACD / CD Player Upgrades
Fidelity is similar to Black Gate capacitors yet at much lower cost
Specifications
Dimensions: 16 mm x 32 mm (W x L)
Lead Spacing: 5 mm
