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.....

Your 5x7 display is my favourite toy; the tunes and graphics in the elevator display always...
Most audio amplifier systems must have preamplifiers with many different characteristics. These...
The LED flasher circuits below operate on a single 1.5 volt battery. The circuit on the upper...
This circuit is a series of electric lamps Flasher. This circuit is designed for flash bulb 12V...
With simplicity being the goal, brain-wave goggles can be constructed from suitable eyewear, such...
This is a low cost fm antenna booster that can be used to listen to program from distant FM...
The circuit shown here is used to switch on a lamp when the tele- phone rings, if the ambient...
You can charge your Mobile Phone from the USB outlet of PC. This simple usb cellphone charger...
The simple circuit offers no isolation, but the simplicity of the circuit combined with cost of...
As shown in Figure II F003 is versatile photographic constituent operational amplifier amplifying...
For its typical application circuit o R2, R3 is a feedback circuit to adjust their ratio,...
CP2128 is a low noise, fixed frequency step-up garden DC / DC converter, in the case where the...
Circuit principle outside into the phone when ringing pulses through C1, R1, D2 to C2 charging...
Circuit shown in Figure 3-121. The key component of electromagnetic holding brake is an...
