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.....

The circuit diagram of the Lie Detector is shown above. It consists of three transistors (TR1 to...
Using a single 555 Timer IC and a small transformer to generate a high voltage, this circuit will...
This charger will charge any 12V lead acid battery including flooded, gel and AGM. It is fully...
By using an RC oscillator and a programmable divider, this counter can run for hours. An...
Voltage to frequency is very useful in many situation, such as transmitting temperature...
The cell phone shield circuit uses two NE555 timer ICs: One as being a very simple astable...
This circuit is used to sense the insertion of a penny. Before the penny is inserted, current is...
The KD2BD Pacsat Modem is a low cost, high performance 1200 bps BPSK modem designed to interface...
This is the schematic for an FM transmitter with 3 to 3. 5 W output power that can be used...
This module is a "tribute" module, based on the awesome Steiner-Parker Synth VCF. Those who know...
This is a simple water level indicator circuit or water level sensor circuit. The circuit is very...
This Home Alarm System is simple, secure, fast and cheap. It`s only few components with maximum...
The resistor in series with the LED in Collector circuit of transistor T1 must be 470 ohm, not...
A multivibrator is a form of relaxation oscillator which comprises two stages that are coupled so...
This timer is based on a simple Monostable Circuit. The length of time the relay remains...
As shown in FIG touch sensor switch circuit diagram The circuit consists of step-down rectifier...
Automatic light is introduced by the telephone block system, the phone rang that night and asked...
BH-SK-I with the voice of a single bond integrated circuit fabrication touch light switch...
