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.....

R1 controls the trip-point of the circuit. adjust it accordingly. to reverse the logic (have the...
This circuit give low level output, when exist enough lighting, that is a detector of light. It...
Gates Gl and G2 together with resistors Rl and R2 form a simple voltage monitor that has a trip...
This circuit shows a method which increases the power capability of a drive system for audio...
This audio amplifier design approach employs TMOS Power FETs operating in a complementary common-...
DAC is short for Digital to Analog Converter. In this article we play around the code Michael...
This is a Logic probe circuit is one, That is suitable for checking the voltage levels in the TTL...
Will LC-based oscillator be able to show performance comparable to crystals in such conditions...
And normally tuning is not easy: you`ll fire the system up and try to notice the spark length,...
The circuit diagram shown here is of a simple DC power delay circuit that is based on an SCR....
The diagram below shows that power supplies don`t have to be complicated, especially in low-power...
V1 and V2 are set to 5V in the simulation, but could also be 10V to eliminate the need for a...
This article explains the construction and working of feedback oscillators with detailed...
Chipmunk BASIC has lots off useful functions. So I wrote a small BASIC file to read the serial...
This circuit is a modified hartley oscillator with a couple of extra components included. The...
