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 unit delivers 0 to 20 volts at up to 4 amps in 0.1 volt increments. The entire device runs...
This panning circuit (short for panoramic control circuit) provides the ability to move the...
The starting ability of the power of intermediate frequency is the most important performance...
The normal assumption is that the phase shift sections are independent of each other. Then using...
The design is based around a pair of 433MHz wireless modules. These can be bought pre-built and...
The design came from the interest of finding a new technique of analog to digital conversion. The...
One day on the 50MHz SSB-QSO, my friends JE3TXU/1 (Mr. Haraguchi) sad to me that he made 50MHz...
Install the PIR module hanging from a 3 metre high mast (to cover 10 metre radius area) and...
The Saver V5. 0 runs simple clock emulation program, turns a night light on and off with preset...
The LTC4425 is a constant-current/constant-voltage linear charger designed to charge a 2-cell...
For maximum efficiency, set MAX_STEPPERS equal to the number of stepper motors that you are...
The most glaring ommision was that the DRUID did not accept confirm codes (ie the solution to the...
As shown for the basic connection circuit ISO120/121 signals and power supply. Each power supply...
Circuit is shown. It consists of a temperature sensor, temperature control of electronic...
