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.....

This project is provided as a "prototyping project" as no PC board has been produced. The...
This circuit uses LEDs to display the beat frequency of two-tone oscillators. Only one LED is on...
The circuit illustrates a way to power CMOS ICs from RS-232C lines. The MAX680 is normally used...
The following is the diagram of 5W audio amplifier circuit which built using power transistor...
Ensure 5/-5 dual supply for chip TL062 IC3. Gnd is common ps ground, let grounds radiate from...
This mini-VOX voice operated relay is based on a circuit published in Silicon Chip, 9/1994, p31....
This is a design circuit for stereo encoder. This circuit is using BH1417 Stereo Encoder. This...
Given favourable radio wave propagation, the shortwave and radio amateur band are chock-a-block...
If you build fused-filament-fabrication parts (the technology that RepRap uses) at room...
This circuit diagram is a UM66 based touch sensitive musical bell. The circuit is built around...
With the values shown, this circuit has a ±0. 025 °C accuracy over 0 ° to 100 °C. The input...
1.53 voltage controlled gain amplifier FET connected between the two inputs to the op amp as...
A sensor SEN1 output DC voltage varies linearly according to the relative humidity. This DC...
As shown, the circuit will combine XTR101 with isolation amplifier ISO100 use, the 4 ~ 20mA...
