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 expander to complement the compressor is shown. An external op amp is used for high slew...
The 20-MHz clock phase-locks to Apple"s Mac II 10-MHz NuBus clock. It uses a simple, inexpensive...
The circuit uses a four-bit latch (Ul). What makes the circuit sequential is that the set input...
This Instructable will show you how to build your own FM radio receiver shield to be used with an...
This is the schematic diagram of very simple headphone amplifier circuit. The circuit built using...
Here is a circuit Power Amplifier with output power of more than 600 Watt speakers with impedance...
This is the circuit diagram of USB powered computer speaker, or it widely known as multimedia...
This Wireless Stereo FM Transmitter built from a monolithic IC. The internal structure of this FM...
Here I will show you an audio amplifier circuit that can be used for walkie talkies, low power...
This is a Simple com port based Microchip PIC microcontroller Programmer, This Programmer is...
The DIY Electronic Siren circuit described here can create three different US-style siren sounds:...
This schematic is for an extremely bare-bones circuit and includes only the needed components to...
This circuit is the result of Andy Collinson research. He has used a photodiode, SFH2030 as an...
