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 circuit stores a single morse code message as bits in an EPROM chip, the message is sent to...
The schematic below illustrates 4 methods of controlling a relay with a digital logic signal....
This is a 8048/IM80C48 Microcomputer with 8 character 16-segment ASCII triplex liquid crystal...
The laser diode·pulser is a simple drive circuit capable of driving the laser diode with 10-A,...
Most of the lovers, especially in audio electronics, it will never escape from this one component...
The CAMD CM8870 CM8870C provides full DTMF receiver capability by integrating both the band-split...
A very simple telephone broadcaster or transmitter which can be used to eavesdrop on a telephone...
This circuit features automatic Exit and Entry delays and a timed Bell Cut-off. It has provision...
Interior lights come on when I enter the car, and most of the time do not go out while driving....
This simple circuit is based on the well-known integrated circuit LM3915. The main characteristic...
The memory part of my Mark 2 system is extremely simple. There are two 32K SRAM chips (actually...
In counter mode it provides 1Hz resolution up to 100Mhz. In timer mode maximum resolution is 0....
The device presented here can generate a complementary clock signal at frequencies of 10Hz to...
FIG. 283 is a blackout emergency lighting controller, it is only the external side in the two...
