A very useful switch that can be controlled from any channel on the typical Futaba or JR radio set up. The switch was designed to trigger the shutter on digital cameras without the encumbrance of a servo glued onto the camera. However, apart from aerial photography, one of the more interestingfeatures is that it can be used to trigger external loads that draw power either from the

receiver battery or another external power source. Of further interest, the switch can be programmed to trigger at a preset interval of time, such as every ten seconds. Equally, the really interesting function is that the output signal can be set up to trigger at a preset interval of time and/or on command from the transmitter. Finally, the output signal can be programmed to be either a short pulse or a continuous ON command. That is flexibility! The power consumption of the switch is 0. 8mA when the Light Emitting Diode (LED) is OFF and 6. 5mA when the LED is ON, so there is no risk of discharging the battery with the switch. Michele`s switch is about as small and as light as you can possibly imagine. In the image, the three wire lead (black, red and white) goes to any spare channel on the receiver. The switch draws power from the receiver battery and gets the command signal on the white wire. Shown below is a simple demonstration of controlling an EXTERNAL object using an EXTERNAL power source. The word EXTERNAL means that the object and the power source are not part of the receiver set up. In the left frame the Schieppati Switch is programmed, is receiving its power from the receiver battery and waiting for a command from the transmitter via the receiver. In the right frame, an ON command has been transmitted, processed by the receiver and interpreted by the Schieppati Switch. The switch can handle up to 36 volts DC and...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
