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.....

If you have no idea what is a "strobo", "strobe", "stroboscopy" or whatever way it is called, it...
A touch-sensing circuit keeps the high-voltage generator cut off until something touches the...
The output of the CA3179 is fed through the Dl!Q1 circuit. Those components serve to boost the...
This Adjustable Analog Timer circuit starts timing when switched on. A green LED lights to show...
IC TDA7052 is a mono output amplifier in 8-comng Head DI package (DIP). The device is designed...
A simple yet accurate automatic, regulated 6/12/24 volt lead acid battery charger circuit is...
The circuit was built on Vero board and tested using a large value electrolytic capacitor instead...
The circuit diagram shown here is a simple circuit DC power delay, which is based on an SCR...
the input signal is processed with an electronic low-pass filter to remove all frequencies above...
This fm rf power amplifier circuit is built with BLY94 transistor which delivers up to 50W at...
Simple, highly sensitive capacitive ON/OFF switch pads change the state of a latch and turn on an...
This circuit is similar to the one above but uses positive feedback to get a little more...
By design, the pump will stop only if the volume set by the four position selector switch has...
A simple IF AGC signal over a wide dynamic range and excellent linearity characteristics, it may...
ETl3X220 is connected to a low-cost single-chip RF-transmitter chip, can provide 10...
Eight-channel isolated as shown in Fig constituted by ISO120 and PWS740 0 ~ 20mA current loop...
