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.....

Well, it's pretty much a PAiA preamp - usual input circuity followed by one half of dual op-amp...
The circuit that has been used is shown in picture 1. Through the experimental part we will...
This is not a sophisticated automatic keyer but it is lot QRP to build and to have fun operating...
The blinking or flashing rate is determined by Ul, a 555 timer integrated circuit. Its output, at...
When a large number of channels are multiplexed, the outputs of two or more multiplexers can be...
This is the schematic of a simple 40W, 12 to 220 V inverter. You don`t believe, this is simple...
Mode control of the average current CMC Require it in order to control the total waveform of...
Experiments with couple of floppy drives I have and it appears that on the step pin, current is...
It is good idea to put this circuit in a box and mark/write each LED with number 1 to 6. Now,...
The circuit of active shortwave antenna presented here boosts weak shortwave signals so that...
The power amplifier circuit using MOSFET has been very popular, because the sound is very...
You can use a Cmos 4001 or a Cmos 4011 in this circuit. They have four - two-input - gates. In...
A common LED driver requirements are: The LED string voltage and the input voltage is very wide...
