Voltmeter Ammeter is a great kit to
measure voltage and current at the same
time. It measures 0-70V or 0-500V voltage
with 100mV resolution and current from 0
to 10A. It's a perfect addition to any power
supply, battery chargers and other
electronic projects where voltage and
current must be monitored. Kit uses
PIC16F876A microcontroller with built-in
ADC (Analog to Digital Converter) to
sample voltage with current and display it
on 16 x 2 backlighted LCD display. It
comes with all the parts required to build
high quality kit, including double-sided
PCB with beautiful red solder mask and
plated through holes. With slight
modification it is possible to measure
higher voltage and current. 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 0.1 Ohm
5W power resistor with higher wattage
resistor. For example 20W 0.1 Ohm
resistor will allow to measure up to 20
Amperes. Kit can also measure AC
voltage if rectifier bridge is added to
voltage input as well as measure and be
supplied by the same power source.

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.

Voltmeter Ammeter is a great kit to
measure voltage and current at the same
time. It measures 0-70V or 0-500V voltage
with 100mV resolution and current from 0
to 10A. It's a perfect addition to any power
supply, battery chargers and other
electronic projects where voltage and
current must be monitored. Kit uses
PIC16F876A microcontroller with built-in
ADC (Analog to Digital Converter) to
sample voltage with current and display it
on 16 x 2 backlighted LCD display. It
comes with all the parts required to build
high quality kit, including double-sided
PCB with beautiful red solder mask and
plated through holes. With slight
modification it is possible to measure
higher voltage and current. 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 0.1 Ohm
5W power resistor with higher wattage
resistor. For example 20W 0.1 Ohm
resistor will allow to measure up to 20
Amperes. Kit can also measure AC
voltage if rectifier bridge is added to
voltage input as well as measure and be
supplied by the same power source.

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.

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.

from 0V up to 70V providing excellent
reading accuracy and 100mV resolution. It
has two input channels for measuring two
voltage sources at the same time. Dual
channel voltmeter kit uses PIC16F876A
microcontroller with built-in ADC
(Analog to Digital Converter) and 16 x 2
backlighted LCD display.
Kit comes with all components required to
build high quality dual channel voltmeter
kit including premium quality PCB.
Voltmeter can also measure AC voltage if
full bridge rectifier is added to voltage
input. Dual channel voltmeter can both
measure and be supplied by the same
power source.

ICL8038 - Precision Waveform
Generator
ICL8038 is a precision waveform
generator with voltage control for
generating accurate sine, square, triangular,
sawtooth and pulse waveforms. The output
frequency was set by resistors and
capacitors and covers a range from 0.001
Hz to more than 300 kHz.

Arduino Prototype is a spectacular
development board fully compatible with
Arduino Pro. It's breadboard compatible so
it can be plugged into a breadboard for
quick prototyping, and it has VCC & GND
power pins available on both sides of
PCB. It's small, power efficient, yet
customizable through onboard 2 x 7
perfboard that can be used for connecting
various sensors and connectors. Arduino
Prototype uses all standard through-hole
components for easy construction, two of
which are hidden underneath IC socket.
Board features 28-PIN DIP IC socket, user
replaceable ATmega328 microcontroller
flashed with Arduino bootloader, 16MHz
crystal resonator and a reset switch. It has
14 digital input/output pins (0-13) of
which 6 can be used as PWM outputs and
6 analog inputs (A0-A5). Arduino
sketches are uploaded through any USBSerial adapter connected to 6-PIN ICSP
female header. Board is supplied by 2-5V
voltage and may be powered by a battery
such as Lithium Ion cell, two AA cells,
external power supply or USB power
adapter.
