[fahadshihab], a young tinkerer, shared his circuit design for a simple remote control using 555 timers ... Once you’ve mastered this, perhaps an AM transmitter is next?

This IR receiver based on ATtiny13 microcontroller is used to control a Media Center box via a remote. The circuit is powered by 20 pin ATX connector pin 9 “+5VSB” because it is the only pin ...

These circuits can be used for receiving AM, CW, and SSB RF transmissions in the medium ... Figure 4 This schematic shows how to use the LM386 as a medium wave regenerative receiver. If the ...

This device is a receiver circuit for a Digital Remote Thermometer. The thermometer operates by converting the sensor’s output voltage, which is calibrated and proportional to the measured temperature ...

Current-mode control loops (particularly the popular ... I came up with a 4- to 20-mA receiver circuit that costs less than $2.60. The circuit in Figure 1 was simulated with MultiSim8 (Electronics ...
