A Receive Signal Decoder: The signal output by the radio control receiver is
a form of PWM. This may be useful for driving servos, but is inconvenient for general
electronic applications. Therefore, several of the circuits on this site convert this
signal into a voltage first. This is performed by this circuit. It is not a project in
its own right, just a building block used by other projects.... (Electronic circuit

Multi Channel RC using CMOS : This transmitter has no separate on/off switch
because the joysticks switch the battery terminal. The receiver has a bigger motor to
drive the wheels and a smaller motor to drive the steering which is not proportional.
There are two speeds in forward and one in reverse. You could add an extra channel to
the receiver by using the spare latch. (added 2/05) |

R/C Switch: This circuit is a so-called "Radio controlled Electronic
Switch". It can be used to switch on/off anything electrical, whatever it is. Here are
a couple of examples: navigation lights, landing gear, sound systems, Glowplug driver,
bomb release, parachute, search lights, gyros, and so on. This circuits connects to a
RC car controller servo output. (Electronic circuit added 4/05) |

Radio Remote Control using DTMF #2: Here is a circuit of a remote control
unit which makes use of the radio frequency signals to control various electrical
appliances. This remote control unit has 4 channels which can be easily extended to
12. This circuit differs from similar circuits in view of its simplicity and a totally
different concept of generating the control signals..... (Circuit / schematic design

RC Network Eliminates Precision Reference: 08/04/94 EDN Design Ideas /
(Electronic circuit added 5/02) The circuit in Fig 1 uses a magneto-resistive sensor
to detect small magnet displacements without resorting to a precision voltage
reference. A simple RC divider takes the place of the reference, eliminating an
expensive component and obviating trimming each circuit.... |

RC network quashes auxiliary Winding in quasiresonant converter: 04/01/04
EDN Design Ideas / (added 1/05) Quasi-square-wave-resonant
converters, also known as QR (quasiresonant) converters, allow the design of flyback-type
SMPSs (switch-mode power supplies) with a reduced EMI (electromagnetic-interference)
signature and improved efficiency. You can achieve so-called QR operation by
authorizing the turn-on of the switching MOSFET when the drain voltage reaches its
minimum—hence, the name valle...... |
