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.....

This timer was designed for people wanting to get tanned but at the same time wishing to avoid an...
Using the thermistor-bridge circuit, you can detect system-cooling air losses caused by filter...
This circuit, instead of dividing by an integer, divides the input signal by +1/2. With the...
Measuring the consumption of a resource that has units by volume can be more tricky than it...
Another feature of this circuit is that you can use the keys "1, 2, 3, 4" of a Philips TV IR...
The cause may be dry solder joints, defective LEDs etc. , but also a flat battery (perhaps due to...
The circuit of the Celsius thermometer in the diagram is based on the well-known Type LM334 from...
Nearly always when a remote control doesn`t work, the underlying problem is elementary: the unit...
To measure the frequency response of the e-meter, a Wein Bridge oscillator, oscilloscope, and...
This phone is loud ringing tone circuit for generating the electricity bell in the old telephone....
For power supply is needed transformer with two individual secondary 12V windings. If you want to...
The modulator and the demodulator (pdf < 10 kb). For the easier tuning of the modem it could have...
As shown in FIG PGA103 constituted by a wide input voltage range of the amplifier. 11.3k with...
Fans (Ceiling) Fifth gear speed control circuit shown in Figure 3-6. It uses capacitor step-down,...
