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 output cable from my 20 MHz function/sweep generator dangled over the side of the workbench,...
The Digi-Tach contains a master-clock circuits (U6)v latch and reset pulse generators...
Tank circuit C2 and L1 is used to tune the transmitter. The antenna is coupled to the transmitter...
The circuit for a SIM card reader is shown here. The circuit uses a CMOS hex inverter and other...
This simple circuit shown int the schematic diagram actives the switch using sound. We can use...
Here is a schematic of a simple water or liquid level sensor relay switch circuit, which can be...
In this card there is a constant current source is used to activate the phone. The LM339 is used...
Zener diode regulator is a basic electronic circuit which is very useful for those interested in...
A very high power and efficiency 100w power amplifier electronic project can be designed using...
This circuit detects the dial tone from a telephone line and decodes the keypad pressed on the...
As it has already been stated the circuit consists of an ultrasonic transmitter and a receiver...
The 555 Timer is an integrated circuit used as a timer, a pulse generator, tone generator and...
A dimming control circuit generates a dimming control signal for determining brightness of at...
Most people believe spark gap Tesla Coils can only be operated from high voltages - typically 4 -...
AD623 integrated 3-way amplifier. Single or dual supply can work with high CMRR and low voltage...
