The servo motor have many utilizes in everything from robotics to puppetry to photography and beyond. These tiny motors can position their output shaft to any position on command and hold that position. Most servos possess a range of motion to about 210.... -
The Boarduino`s small footprint made me want to see how small of a device I could whip up in an hour from some fairly complex components. So I decided to see how small the combination of a Boarduino, a Wii Nunchuck, and a hobby servo motor could be. Here`s a.... -
With the remote control at your fingertips, you are the only one to decide when and if the parachute should deploy. Ideally, in a very large open field, you can wait until after apogee to deploy the parachute. Depending on wind conditions, you can decide.... -
The movement of the servo depends on the output value of the photoresistors. The impedance of the sensors varies with the light that incident on them. The position of the servo always changes toward the sensor with less light. There are four light sensors..... -
As we presented in another article the A3952S integrated circuit ( designed by Allegro MicroSystems ) can be used to design very simple and useful motor driver circuits. In the precedent article was presented a simple bipolar stepper motor driver circuit.... -
Built servo tester cicuit as shown - only action is for the servo to twitch when power switched on, cannot see any real reason why wont work - ideas anyone I haven`t built this circuit yet so I can`t comment on the circuits efficacy. I do have some.... -
Servo motors have many uses in everything from robotics to puppetry to photography and beyond. These little motors can position their output shaft to any position on command and hold that position. Most servos have a range of motion to about 210 degrees and.... -
The Servo Timer II was primarily designed for parachute deployment on water rockets, but can be used for other applications. The timer controls a single RC servo motor that can open a latch on a parachute door. Once triggered the timer waits a set amount of.... -
What is a servo? A servo is a small motor that you can position at any angle very accurately. It contains internal circuits that will automatically maintain.... -

Servos became valuable products for any variety of plans, like robotics, automation or only remotely controlling some thing, for example model vehicle steering. They`re reasonably low-priced and also simple to have hold of, however controlling them can be a.... -
This circuit operates an automotive windscreen washer pump to fill a 20-litre drum from a 205-litre water reservoir. The drum is suspended above a drip line, which irrigates a vegetable garden. Two stainless steel probes mounted in the drum act as sensors.... -
There are times when a small servo tester for modeling comes in very useful. Everybody who regularly works with servos will know several instances when such a servo tester will come in handy. The function of a servo tester is to generate a pulsing signal.... -
This is a control of servo motors in software programming using PIC 16C71 microcontroller. The input signals are between 0 - 5V delivered by .... -
The following circuit shows about servo motor driver. This circuit based on the 12F675 IC. Features: Timer 0 timing, single control line from .... -
SA9618A CAN be used for ALPC and signal conversion between CD optical pickup and decoding chip. This IC incorporates an interconnection to general CD optical pickup Photodiode bias voltage VREF generation circuit, RF Amplifier and ALPC circuit. (This IC is.... -
This circuit allows a smaller control voltage to inversely linearly control a larger output voltage Vo. Another feature is that Vsp the supply to the op-amps can be lower than the output voltage so in theory this circuit could control a output voltage of any.... -
The disadvantage of the circuit above is that the supply of the op-amp is tied to the HV supply. Most op-amps are limited to around 30V on the supply, so the circuit wont work for higher output voltages. The circuit below avoids this this problem by.... -
This is a simple servo tester which will comprehensively test the capabilities of almost any modern servo. It has two pushbuttons, CENTRE and SWEEP and a potentiometer which works as follows:.. -
I done some more playing with the LTspice simulation of Dxvideo`s preamp-with-DC-Servo circuit. I have been using the .four command to have spice.... -
Hi all, I am planning to make another LM4702 amp with SAP15 devices (which is published in another topic in this forum). The amp will be in non.... -
Apex seems i begin to love this amp the corrected clear schematic is this with different R14 values(tried 22k,30k,56k) and different supply.... -
This projects will describe a simple Servo Reverser that can be cheaply built using a CD4001 NOR gate, 4 resistors, 3 capacitors and one variable potentiometer (see schematic below)... -
With a bit of adeptness, you can build an electronic scales based on a servo motor. Depending on the type of servo you use, it can measure weights of up to around five kilograms (11 lbs) with reasonable accuracy. If you examine the operating principle of a.... -
The all-analog circuit presented controls the rateat which a miniature turbojet engine can be throttled. Increasing or decreasing the throttle too quickly on a miniature turbojet engine, or any jet engine, can lead to quick failure in flight, causing....

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.....
