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.....

Using a precision oscillator and a few CMOS counters, you can build a precise, very low...
The compact test probe provides rapid "measurement" of voltage levels at digital gates, fuses,...
An audio signal applied to VI is passed through the operational amplifier 741, U2. After being...
This is a simple musical alarm circuit that produces a musical tone when water or some conducting...
Here`s the circuit for a simple electronic delay detonator circuit diagram. The overall circuit...
Here the schematic diagram of mic preamplifier which build based on operational amplifier TC251....
Make it a habit to check the temperature gauge every 5-10 miles. The temperature gauge can tell...
This design adapts such a high voltage flash for use on a low voltage camera by using an...
We know that every inductor coil has a certain amount of resistance and the coil should have...
BU8732AKV is a PCM codec IC for digital cellular phones. This includes plenty of Analog input /...
The TRF1400 VHF/UHF RZ ASK remote control receiver is specifically designed for RZ ASK...
I used some schematics from Elliot sound products to help with this circuit. L-In and R-In come...
This TDA2030 35 watt audio amplifier circuit project is designed to provide an output power of 35...
The LTC3221 family are micropower charge pump DC/DC converters that produce a regulated output at...
This is a universal four-digit keypad-operated switch - with a difference. Instead of entering...
As shown in a practical single-tube constant current charger, which play a constant role...
Circuit work process is: When the momentary switch S between, since the voltage across the...
