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.....

A simple FM transmitter links your home-entertainment system to a portable radio that can be...
A pair of timer IC"s are the heart of a circuit that simulates the warbling bee-haw of a British...
One section of the precision audio frequency generator uses an electret microphone element to...
This circuit was designed for use in a hifi showroom, where a choice of speakers could be...
This is an improved IR remote control extender circuit. It has high noise immunity, is resistant...
The circuit for a SIM card reader is shown here. The circuit uses a CMOS hex inverter and other...
Here is a project Device switching using password by innovative group Dreamlover technology,...
Using the LT3692 dual current mode PWM step-down DC DC converter circuit with two internal 3. 5A...
Don`t forget to seal your wire splices with heat shrink. It adds tensile strength to wires, is...
Here is the remote control tester circuit. This circuit is really a simple and easy tester for...
This is a simplified version of the Universal Keypad-Operated Switch. I have modified the design...
This accurate one-pulse-per-second clock is made with a few common parts and driven from a 50 or...
VCO is definitely useful in so many RF projects, wide band Ghz VCO get more concern than VHF/UHF...
This circuit was originally a type of power-delay control circuit, the delay time by the timing...
Autotransformer voltage starting, starting time 30-60s adjustable. Figure, SDJ electrode liquid...
Circuit using the form shown in Figure 1-36, the feedback circuit and the bias circuit...
