apacity of the experiment. General resistive load different, it by a 1.2 50V voltage range adjustment load current to maintain a constant load test. Circuit power MOS-FET (VTl) and the sense resistor (RA a RD) load power consumption, battery used to isolate and solve the problem of grounding. RP2 10-turn potentiometer, improve the accuracy and resolution. Wiper RP2 for Al provides a reference voltage through feedback to ensure prosperous wiper voltage present on R5, forcing the required load current through the VT1. Al bias current (up to 3nA) via an RD series resistor RA circulation, the current times and four resistors (100 obtained 30OnV error voltage. This compared with the error voltage to provide the noninverting input of A1 by the voltage RP2 is small, negligible .Cl for enhancing stability, RA RD series resistor can be a 4 range of output current. During calibration, access the battery and the circuit, and then access 5V/l0A power as experimental load RL. In RP2 for the next full-scale, adjusting RPl and read the exact 10 OOA current with ammeter. In order to check the linearity of the circuit, to accurately adjust the RP2, and reads 5, OOA current with ammeter. RB RD adjust a resistance calibration to the rest of the current range.
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.....
