This is an 8 Channel IR Remote Transmitter and Receiver based on SM5021 encoder and SM5032 decoder ICs. It is simple to build and will allow you to remotely control various electronic projects. IR Remote Control provides 2 latched and 6 momentary outputs that could be used to control your favorite devices such as amplifier's volume control and selection of audio sources, wireless light control, light dimmers, robotic devices, RC cars, computer, home appliances, and many other cool gadgets.
Build Accurate LC 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. 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 and reset function to make sure the readings are as accurate as possible ... [more]
