Radio Controlled 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. __ Designed by Tony van Roon VA3AVR

Radio Remote Control using DTMF - 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 __ Designed by Radioland.net
RC Controlled Digital Camera - The aim of this project was to get a digital camera into a small electric radio controlled (RC) airplane and still have it fly. The airplane shown, a park flyer, weighs between 400 and 550 grams depending on the size of battery and wing configuration that I use __ Contact r dot p @ webone.com.au
RC Network Eliminates Precision Reference - 08/04/94 EDN Design Ideas: 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 Design by Christophe Basso, European Synchrotron Radiation Facility, Grenoble, France
RC Receiver Hosts Two Independent Switches - 06/06/96 EDN Design Ideas: Typical inexpensive radio-control (RC] systems have servo-motor outputs, but no on/off switch outputs. You can add two independent RC switches to a system without making any transmitter or receiver modifications Design by Tom Howell, US Army ARDEC, Picatinny Arsenal, Dover, NJ
RCFS - Our original R/C Fail-Safe project. it has been replaced by RCFS-V2 (see above). __ Designed by T. Black
RCFS-V2 - Add R/C Fail-Safe features to any servo. A microcontroller continuously monitors the servo's pulse signal and it takes over if the transmitted R/C signal is bad. For use with PPM (AM/FM) Rx's. __ Designed by T. Black
RC-Mon - Build your own low cost R/C frequency monitor. You can use this to check for interference from other transmitters and glitch inducing noise sources at your flying site. __ Designed by T. Black
RCST - R/C Servo Tester. This pocket sized device is perfect for checking and testing your servos. it features digital accuracy and convenient features, including a servo exercise mode. __ Designed by T. Black
Receive Signal Decoder - The signal output by 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 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 or projects __ Designed by Paul Hill
Simple Circuit FM Transmitter with a Single Transistor - Mini FM transmitters take place as one of the standard circuit types in an amateur electronics fan's beginning steps. When done right, they provide very clear wireless sound transmission through an ordinary FM radio over a remarkable distance. I've seen lots of designs through the years, some of them were so simple, some of them were powerful, some of them were hard to build etc. __ Designed by Kamran Ahmed-UK
Simple Circuit two transistor Amplifier - This electronic circuit design shows a simple two transistor amplifier with feedback. it offers a reasonably high impedance while providing a low output impedance. it is an ideal transistor amplifier circuit for applications where a higher level of gain is required than that which would be provided by a single transistor stage. __
Simplest R/C Receiver - A simple and effective receiver for actuating garage doors, starter motors, alarms, warning systems and numerous other possibilities. The SCR, which has a very low trigger current of 30 uA is typical -- it requires an input power of only 30 uW to activate the relay. A high Q tuned antenna circuit assures rejection of spurious signals. A whip or wire antenna is adequate up to 100 feet from a low power transistor transmitter. A momentary-off switch resets the circuit. __ Designed by Tony van Roon VA3AVR
The Battery Eliminator - The Battery Eliminator Circuit, or BEC, is one of the tools at our disposal to reduce weight in our electric models. A typical four-cell 600mAh nickel cadmium (NIC d) battery supplied. __ Designed by Stefan Vorketter
The HC11 Controls the Stepper - Simple circuit with 16-pin Nitron chip 68HC908, easy analog setting, source code with IC C08. New s-record for 8-pin 68HC908QT2! __ Designed by Ludwig Orgler-Fachingenieur Elektrotechnik
Thermal Peak Detection Charger - The electric model aircraft and car industries have produced a bewildering array of field chargers for NIC d motor battery packs. These range from simple 6 or 7 cell chargers consisting of a resistor and mechanical timer, to more complex chargers with peak detection, cycling, and the ability to handle 36 cell packs __ Designed by Stefan Vorkoettert
Top RC-Gun - This is our original R/C aerial combat system. Simple one-IC construction. Please note that it has been replaced by the Top RC-Gun AWS project (see link above). __ Designed by T. Black
Top RC-Gun AWS - This fun R/C aerial combat system lets you command your own dog fight missions. it is based on the HobbyZone Combat module. __ Designed by T. Black
Versatile Miniature High-Rate ESC with BEC & Brake - This electronic speed control (ESC) for brushed motors combines the features of two of my earlier designs. One was a high-rate 30A ESC with a brake, and the other a high-rate 12A ESC with a BEC (receiver battery eliminator circuit). __ Designed by Stefan Vorketter
Xenon-9 Speed Controller - The FET speed controller is made up of several smaller blocks, each which is quite easy to understand. The R. C. transmitter sends control information to the receiver as a string of width modulated pulses. The receiver sorts these out __ Contact Collin Mitchell
