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.....

The Hot Springs tanks and circuit board should be mounted in a location that is free of ambient...
This project uses a four-point resistance measurement process also known as the Kelvin method....
The output of the CA3179 is fed through the Dl!Q1 circuit. Those components serve to boost the...
In this Arduino-based project, we will build a lamp with multiple light displays: color...
The two final power of TR2-TR4 should be mounted on heatsink the right size, otherwise they will...
This is the DOD Overdrive 250 preamp circuit diagram. The DOD Overdrive 250 is Yet Another 741...
After fail finishing the robot for the competition, I stopped updating my blog for a while. This...
The ADAU1701 datasheet recommends on p18 that MP11 be used to derive MCLK. Now MP11 also serves...
Circuits available for indicating water level is usually consist of LEDs to indicate the liquid...
The Comtech has become the de facto standard now for those entering the Amateur TV scene. Sadly...
Using two gates from a CMOS 4011 NAND chip, a simple Squarewave oscillator can br made....
In many cases, the dimmer presented here may be built into a wall-mounted box containing the...
Is it possible to make an op-amp out of nothing but 555 chips and passive components? Not a...
3P10 circuit shown in FIG. It uses a bidirectional thyristor control. Adjustment potentiometer...
