This is a low-input impedance conversion circuit with reference resistor RS being connected to the amplifier`s feedback loop and input impedance in approximately zero, and the input current flows into Al`s output end through Rs. The maximum switching current....

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.....
In the typical dynamo charging circuit, B+ and B- are the battery connections. D+ and D- go to...
Here is a circuit that implements phase-control of heaters, adjusting their power smoothly from...
A motor driver! I'm sure you knew that already but that's what it is. A motor driver is required...
The operation of the circuit is like an enabled inverter, that is, the output Y = B provided A is...
This circuit uses only one IC, produces a pleasant tone, and sports a single control for...
The above circuit uses RS232 for interfacing with PC. It is very simple circuit & works very well...
To apperceive whether it is freezing you alone charge to admeasurement the temperature. This has...
If you want to build a 7 to 128 demux with 3-to-8 and 4-to-16 demuxes, then put the 3 high bits...
This circuit is design circuit for a differential analog circuit switches. The FM1208 monolithic...
This is a 5V to 12V DC-DC step-up (boost) converter circuitry that is especially ideal for the...
Ability to control lights and fans wirelessly has long moved from being an expensive proposition...
This is the circuit diagram of a very powerful and efficient Ni-MH battery charger using IC...
I would like to learn if this circuit will invert the input signal or not. The opamp is single...
