2-Channel IR Relay Controller
Posted on Thursday, April 8, 2010   •   Category: Remote Control


This project is a 2 channel infrared (IR) remote controlled relay driver with power saving. It works with 12-bit SIRC IR signals as used by Sony remote controls. The board uses Microchip's low cost PIC10F200 microcontroller along with a handful of easy to find components making this possibly the lowest cost remote controlled relay driver around. The controller also features a power save feature which reduces the relay holding voltage to 50% of the relays nominal operating voltage once the relay has switched on.

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]
