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.....
.
Based on Valvo FD-1A module, TBA120, and MC1310. Operation of the receiver is based on the phase...
Many times we needed a variety of voltages, from a battery 12V. With the circuit, we can take...
Any good power transistor can be used in this circuit. The base resistor should be adjusted to...
See (a) for the timing information for the alarm circuit in (b). When leaving your vehicle, flip...
This VFO circuit covers from 2.13 to 2.58 MHz and is intended for use with an external mixer to...
Terminology TS555 a single CMOS timer which offers very low power consumption and high frequency...
The PSU you`re referring to doesn`t look extraordinarily large to me.Eagle should be able to...
The power supply is just a 7812 voltage regulator followed by an op-amp set to 6V to create a...
This set of two circuits from the basis for a very simple light wave transmitter. A LASER beam is...
This is my first successful vacuum tube project. The output of this small amplifier in which a...
The 555 Astable generates a clock for this circuit, an oscillator giving a square wave output at...
A 1Hz pulse/frequency generator using the popular timer IC 555 which is wired as an Astable...
This is a rather old project I`ve done around 2005 but was not published on my website until now....
As shown by FIG MAX4100/4101 unit gain buffer circuit constituted. This circuit uses a small...
