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 is a very simple circuit to interface a current loop sensor to an input which is designed...
The 555 timer produces a rapid series of pulses whenever switch SI is open. These pulses are...
The LM101A provides gain and buffers the input from storage capacitor C2. R2 adds a zero in the...
This oscillator-driver produces a deafening sound of about 3 kHz, modulated with a 10-Hz warble....
This circuit is based around the PIC16LF1937 microcontroller. This chip is actually a small...
Here is a 10W MOSFET audio amplifier circuit, sound that only requires a single source. Single...
The 220V AC mains supply is downconverted to 9V AC by transformer X1. The transformer output is...
The Supertex HV440 is used for implementing a pulse width modulated high voltage ring generator...
Advantages and disadvantages of different power supply technologies as well as the design...
This circuit might also be of interest to people making pre-amps for electret and externally...
The microcontroller is an AT90S8535-P in a DIP40 package. Note that this microcontroller is pin...
All of ACC`s repeater and remote base products support control of synthesized remote base...
The crystal radio gets its name from the galena crystal (lead sulfide) used to rectify the...
Take a V2-400 and use the sub-woofer amplifier for the center channel. Then add a separate...
Circuit works: This is an AC blown fuse alarm. When BX is not when blown, 220 V AC voltage...
Charging time relay circuit 2 It is a long delay circuit. When the capacitor C is 5000yF, the...
