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.....

A1 amplifies and regulates the signal from the spark coil. A2 converts frequency to voltage so...
This FET probe has an input impedance of 10 M!J shunted by 8 pF. Eliminating the protective...
Three-terminal regulator device (LM78LXX) has Vout = Vm until the input rises 1.5 to 2 V above...
This circuit is based around the PIC 16C84 (or PIC 16F84) microcontroller. This chip is actually...
This electronic project is a simple microphone preamplifier based on the LM318 op amp. The LM318...
This Line Following Robot sensor or surface scanner for robots is a very simple, stamp-sized,...
Also you have mentioned that the op amp in the second stage gets damaged. Can you confirm that by...
Any NPN transistor can be used. The author used a 2N3904, but a 2N2222A should work just as well....
By making this RF amplifier small power transmitters of 200 mW, can be transformed into a power...
This wireless FM microphone is simple to build and it has a useful transmitting range (over 300...
The V2. 2 PCB has 4 spare connectors (X11 to X14) these can be used for various inputs and...
the dc/dc converter is 110/220->12v not the other way. so the 12V takes the place of the battery,...
This is The Fet Amplifier circuit. This circuit uses FET transistor. The gate of the FET must be...
Start within 16W2D single ended energy saving lamp dedicated electronic ballast circuit shown in...
