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 AD844 was still used, but this time the feedback loop went all the way from output and back...
A single op amp, one fourth of an LM324 quad op amp, is configured as a standard inverting...
The IR diode"s flash rate is determined by the value of CI, a 220-Â¥ capacitor that sets the...
The ac ringing voltage (typically 40 to 90 V at 26 Hz) is rectified by U1, the tone-ringer IC,...
This system operates on the principle that capacitance loading of an oscillator will lower its...
The first two are `passive` elements and op-amp is an `active` element. Also: the first two are...
The circuit is designed to be fitted into a small box and then fitted into your backbox (the...
The following is a series of simple TV transmitter using negative using sound modulation and PAL...
This featured circuit is a musical doorbell. After the button S1 is pressed, a short melody is...
We cover the hardware and the software and give a full design for a 12/24V DC 20A charge...
I've designed a high-voltage generator which uses a flyback transformer as the output stage....
220V AC by R3 buck figure, VDI rectifier, VD2 and C3 filtered output voltage of about 3,9V DC...
As shown in FIG constituted by OPA340 INA321/322 output buffer circuit. INA321/322 optimum load...
BA532 and low frequency power amplifier circuit for OTL circuit, output power up to 5.8W,...
