The following diagram is the Clock Generator circuit diagram which build based on NAND Gate logic IC. You may use IC 7400 or 4011 for this circuit. The 7400 is a TTL type, while 4011 is CMOS type. IC 4011 is cheaper than 7400 but the 7400 is faster than 4011. Circuit Notes: Excellent clock. This is the 1Hz clock generator circuit with Chip On Boa

rd (COB). Commonly, the circuits to produce 1Hz clock for digital clock and counter circuits applications implement ICs in conjunction with a crystal and trimmer capacitors, etc. Even so, equivalent or improved accuracy could be obtained working with a chip-on-board (COB) device found inside a. This is the door bell circuit with flashing LEDs to make the circuit more attractive. IC1 (NE555) is applied right here as being a clock generator. It is actually set up as an astable multivibrator whose frequency could be altered using the support of potensiometer VR1. The clock pulses received from IC1 are fed to. This is a really simple sound effect generator based single sound generator chip UM3561. The UM3561 will generate four kinds of sound effects. The basic operation is that the UM3561 will generate the sound signal, then the signal delivered to 2N3706 (as speaker driver) to be amplified so you can hear the sound from a. Here the low cost and easy build circuit of ticking bomb sound generator. This circuit generates a sound matching to a loud clicking clock. The frequency of the tick is altered through the 220k potensiometer part. The circuit gets going by charging the 2. 2uF and when 0. 65v is on the base of the NPN transistor, . This is the schematic diagram of Western music generator circuit based on single IC HT82207. This circuit is able to take you towards the world of the Wild West. The western music already...
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.....
