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.....

These two projects , Wah and Fuzz, are the results of a modification to a Morley dual channel...
This circuit, designed on request, has proven to be useful to indicate when the voltage in a...
Most amps acoustic frequencies that make our readers, instead of a transformer power, sometimes...
When you need connect your Microcontroller Project to COM port in PC you need RS 232 converter....
The on-off-type DC/ DC converter has two kinds of operating modes: One kind keeps the switch duty...
This circuit uses the LM358 operational amplifiers (or any single supply op amp) to generate a...
Here is the schematic of a water level alarm circuit. The circuit will work as a water level...
This circuit inverter converts 12V DC battery to AC 22oV as the replacement of home energy. The...
The TS4956 is a complete Audio system device with three dedicated outputs, one stereo Headphone...
This application note presents alternate RF matching networks for the MAX2653 SiGe LNA, tuned for...
With sine-wave input, RCA CA3046 transistor array connected as VCO can be used as low-distortion...
Analog switch (double loop, double-break) and differential modulation amplifier complete the...
As shown in FIG constituted by ISO102 OPA27 500VDV DC current measurement circuit. Circuit...
