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 simple circuit can monitor the charging process in 12 Volt Lead Acid battery or Tubular...
The LMV116 is an enhanced slew rate version of the LMH6645. The high speed LMH devices are very...
Martin KH6MB designed an antenna tuner for use with end-fed half-wave vertical antennas for use...
Is it possible to alter a single-cycle datapath so that an add instruction not only writes to a...
This is a very simple yet effective circuit in which the equipments connected at the so called...
From ages electron-magnetic relays are being used as switches to control high voltage devices....
This is simply (4) 1N4148 diodes connected in series with a thermal anticipation resistor (R1)...
This is a 1 watt fm amplifier with a good design that can be used to amplify a rf signal in the...
a programmable clock timer circuit that uses individual LEDs to indicate hours and minutes. 12...
In the picture above, Oscium`s iMSO-104 oscilloscope is measuring the output waveform of an...
This is a classic 2 transistor astable multivibrator. Many other NPN small signal or switching...
The Command radio is a description of the radio function, rather than a specific model. The...
Shown as an infrared receiver circuit. The figure shows that the circuit is mainly composed of an...
Circuit shown in Figure 6-24. Both ends of the relay coil in parallel with a resistor Rf or...
