3 Channel IR Remote Control
This project is a 3-channel IR remote control with 3 output
relay and easy to build. Features: CPU PIC12F629 at 4MHz crystal for Tx/Rx, 3 channel output relay, The Tx use sleep mode for saving battery power, Use Phillips RC5 protocol, distance more than 7 m, Easy circuit to build and assembly
and small amount of components. Uses RC5 protocol which is probably the most used by hobbyists, probably because the wide availability of cheap remote controls and easy to understand.

Build your own 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 "Zero Out" function to make sure the readings are as accurate as possible ... [more] |
