Accurate LC Meter
Build your own Accurate LC Meter (Capacitance Inductance
Meter) and start making your own coils and inductors. This LC
Meter allows to measure incredibly small inductances making
it perfect tool for making all types of RF coils and inductors. LC
Meter can measure inductances starting from 10nH - 1000nH,
1uH - 1000uH, 1mH - 100mH and capacitances from 0.1pF up
to 900nF. The circuit includes an auto ranging as well as reset
switch and produces very accurate and stable readings.
PIC Volt Ampere Meter
Volt Ampere Meter measures voltage of 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 16x2 backlighted LCD.
60MHz Frequency Meter / Counter
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
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.
BA1404 HI-FI Stereo FM Transmitter
Be "On Air" with your own radio station! BA1404 HI-FI Stereo
FM Transmitter broadcasts high quality stereo signal in 88MHz
- 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
