Frequency Meter / Counter measures frequency from 10Hz to
60MHz with 10Hz resolution. It is a very useful bench test
equipment for testing and finding out the frequency of various
devices with unknown frequency such as oscillators, radio
receivers, transmitters, function generators, crystals, etc.
1Hz - 2MHz XR2206 Function Generator produces high quality
sine, square and triangle waveforms of high-stability and
accuracy. The output waveforms can be both amplitude and
frequency modulated. Output of 1Hz - 2MHz XR2206 Function
Generator can be connected directly to 60MHz Counter for
setting precise frequency output.

- 108MHz FM band. It can be connected to any type of stereo
audio source such as iPod, Computer, Laptop, CD Player,
Walkman, Television, Satellite Receiver, Tape Deck or other
stereo system to transmit stereo sound with excellent clarity
throughout your home, office, yard or camp ground.
USB IO Board
USB IO Board is a tiny spectacular little development board /
parallel port replacement featuring PIC18F2455/PIC18F2550
microcontroller. USB IO Board is compatible with Windows /
Mac OSX / Linux computers. When attached to Windows IO
board will show up as RS232 COM port. You can control 16
individual microcontroller I/O pins by sending simple serial
commands. USB IO Board is self-powered by USB port and can
provide up to 500mA for electronic projects. USB IO Board is
breadboard compatible.
ESR Meter / Capacitance / Inductance /
Transistor Tester Kit
ESR Meter kit is an amazing multimeter that measures ESR
values, capacitance (100pF - 20,000uF), inductance,
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.
Audiophile Headphone Amplifier Kit
Audiophile headphone amplifier kit includes high quality audio
grade components such as Burr Brown OPA2134 opamp, ALPS
volume control potentiometer, Ti TLE2426 rail splitter, Ultra-
Low ESR 220uF/25V Panasonic FM filtering capacitors, High
quality WIMA input and decoupling capacitors and Vishay Dale
resistors. 8-DIP machined IC socket allows to swap OPA2134
with many other dual opamp chips such as OPA2132,
OPA2227, OPA2228, dual OPA132, OPA627, etc. Headphone
amplifier is small enough to fit in Altoids tin box, and thanks to
low power consumption may be supplied from a single 9V
battery.
