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.....

During summer nights, the temperature is initially quite high. As time passes, the temperature...
The iriput signal is fed via SKI to the first active stage built around ICl. Configured as a...
The DG419looks into the high input impedance of the op amp, so the effects of Rvs(o"l are...
This is a schematic for a straightforward direct-conversion heterodyne detector, having a tuning...
An oscillator-only transmitter sounds like the simplest possible means of getting on the radio...
Difficult to observe in order to solve the leaning phase in adjusting the electric transmission...
Q1, Q2 & Q3 form a high impedance super-Darlington that drives the relay, amplifying the 50 or...
A dual DC motor controller that utilizes an H-bridge controller chip. As well as the basic...
Diode, D13, provides different timings for the forward sweep, and the retrace which can be faster...
To set the above amplifier up, set R1 to max and R12 to 0. After doing this successfully, power...
A simple USB powered lamp that can be used to light your desktop during power failures. The...
It is based on the Miller solar engine and has no digital electronics involved. But before we get...
The above pictured schematic diagram is just a standard constant current model with a added...
The Wien-bridge sine-wave oscillator uses a light bulb to stabilize its amplitude. The circuit in...
This article describes a 2 meter amplifier capable of running 25-30 watts output. More than 35...
Before one magnet was 2x2x3 cm, now it is a round one 1. 5 x 2 cm only. This makes a huge...
This application note describes creating a dumb framebuffer with PAL composite TV output for the...
You can use a Cmos 4001 or a Cmos 4011 in this circuit. They have four - two-input - gates. In...
220V AC by the step-down transformer T, a diode VDI-VD4 bridge rectifier and filter capacitor CI,...
