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.....

The Electronic Dazer is a modern, portable, personal-protection appliance. It generates hight...
This supply can serve as a battery eliminator for various devices (such as tape recorders, small
The ECM circuit consists of four sections, as shown in the block diagram. A power converter...
The Quad Laser Head ( A2050 ) is a LWDAQ device that drives four laser diodes. The A2050 was...
This project illustrates how to use an ATTiny microcontroller and an RGB LED to create a coloured...
A powerful buzzer in the room, combined with a pushbutton at the bottom of the stairs or in the...
There are two schematic diagrams showing a series and a parallel circuit that Tesla could have...
The goal was to make a compass sensor compatible with the RCX and have it only take one sensor...
Main Power Amplifier OCL 100watt by MJ802, MJ4502. May pleasing of friends at like firm bass and...
This RS232 power supply circuit diagram is an simple RS-232 Line Driver Power Supply, that...
The Precision VXO (PVXO) and its matching Crystal Test Fixture (CTF) were created to provide a...
This is basically how the Scorpion jammers work except that instead of sending back a shifted...
A stepper motor is a motor controlled by a series of electromagnetic coils. The center shaft has...
This alarm is designed to sound its Siren only once. That is - when the alarm is activated - the...
This article describes the use of super-regenerative FM receiver FM receiver principle, due to...
As shown for the 20Hz signal generator, may be applied to the telephone ringing system, the...
