about-face S1 momentarily. This beating acts as a alarm beating for the decade adverse (IC2) which advances by one calculation on anniversary alternating alarm beating or the advance of about-face S1. Ten presets (VR1 through VR10), set for altered ethics by balloon and error, are acclimated at the ten outputs of IC2. But back alone one achievemen

t of IC2 is aerial at a time, alone one preset (at called output) finer comes in alternation with timing resistors R4 and R5 affiliated in the ambit of timer IC3 which functions in astable mode. As presets VR1 through VR10 are set for altered values, altered time periods (or frequencies) for astable multivibrator IC3 can be selected. The achievement of IC3 is activated to pnp disciplinarian transistor T1 (TIP32) for active the final ability transistor T2 (2N3055) which in about-face drives the wiper motor at the called ambit speed. The ability accumulation for the wiper motor as able-bodied as the ambit is broke from the vehicle ½s array itself. The continuance of monostable multivibrator IC1 is set for a about one additional period.
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.....
