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...
This project describes how to build a "soft touch" switch. By "soft touch" we mean that you have...
This nonlinear, passive filter circuit rejects ripple (or unwanted but fairly steady-voltage)...
This CW transmitter has an output of up to 3 W. By using 24 V on Q2, up to 10 W output can be...
The Proximity Camera Head (A2047) is a Long-Wire Data Acquisition ( LWDAQ ) Device that reads out...
About a do-it-yourself alarm arrangement body with PIC18F452. It`s a abundant amusement activity...
This FM transmitter circuit uses four radio abundance stages: a VHF oscillator congenital about...
A very simple supercapacitor charger electronic project can be designed using the LTC3625 IC...
The idea for this circuit came when the author had problems with the wireless speedometer on his...
Here is the circuit diagram of IC Controlled Emergancy Light With Charger or simply 12V to 220V...
This is a small footprint 50% duty cycle square wave oscillator with variable frequency from...
It is shown using the MCS-51 series single-chip interface circuit 8051. Chip SED13 35 dot matrix...
