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.....

Take care with transmitter circuits. It is illegal in most countries to operate radio...
Volt regulators such as the LM708, and LM317 series (and others) sometimes need to provide a...
A suitable pilot larnp is illuminated by a small sample of rf and energizes an inexpensive solar...
This circuit is based upon the change of frequency of the function generator with the input...
This is the scheme diagram of 500W power inverter circuit which build using 10 pieces of...
This is the circuit diagram of touch activated alarm system which still activated on load...
Provide your radio with a actual cord signal, again acclimatize the HIGH LEVEL pot to the...
AC power is supplied via AC Fuse F1 and Power On/Off switch S1 to 6. 3V filament transformer T1....
A used USAT F3A found it`s way into my possession today. I wasn`t planning on this, it just sort...
A 315bl excavator. Engine intermittently shut off on its own, but will start back up without a...
This circuit is a 555 timer IC connected as a square-wave generator. Its base frequency is...
As shown in FIG grounds efficient, low-power step-up DC-DC converter MAX761 and a few external...
