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.....

Input Amplifier Module: a low noise circuit equipped with a variable voltage-gain (10 - 100)...
This is a classic divider of frequency via two. It is achieved with a classic circuit...
This FM radio-controlled anti- theft alarm can be used with any vehicle having 6- to 12-volt DC...
The circuit uses a 4011 CMOS NAND gate, a pair of diodes and an NPN power transistor to provide a...
This circuit produces a symmetrical waveform when dividing by either 2 or 3. The Divide Select...
The circuit has a frequency response that ranges from 100 Hz to 3 MHz; the gain is about 30 dB....
A 555 and a dual 556 timer generate a rudimentary video signal, as shown in the schematic. The...
This is a 2 x 70W audio power amplifier circuit which built using single IC STA550. The amplifier...
So you`re either revved up about building one of these for yourself or you`re just reading on...
And here is the final part of the entry, starting with the schematic that I finally used. The...
This is a Sony Triniton, Model KV-20M10, manufactured July 1995. There are no blinking lights...
Construction of a radio telephone integrator and created my first radio phone / repeater. I had...
The power supply has been simplified- Power transformers and rectifiers have been omitted and...
The system uses optical fingerprint sensor with ARM Cortex M3 core STMicroelectronics 32-bit...
DK-5A, DK- 5AD AC power control circuit circuit shown in Figure 6-77. Figure, SBz the closing...
A constant current source of the differential amplifier circuit (2) having a constant current...
After the power is turned on, 220V AC by the step-down transformer T, VDI ~ VD4 bridge rectifier...
