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.....

The 22 watt amp is easy to build, and very inexpensive. The circuit can be used as a booster in a...
This Project is made up with AT89C2051 and the RTC DS1307. It has a large Seven segment display....
The LCD display is represented by the connector X1. It has a HD44780 compatible LCD controller...
I made the power supply which makes about +30V with +5V power supply. The direct current is...
The ATMEL, with family AVR, was consolidated in the field of microcontrollers. The...
When a gate voltage is applied, Ql is turned on and capacitor C is charged via the attack pot in...
Uses a low cost CMOS IC to tum four LEDs on and off at a rate that is set by the values of R1,...
A 1-V amplitude pulse triggers SCSl, but has insufficient amplitude to trigger SCS2. A 3-V input...
The module provide a pre wired multiplex of 4-digit common anode LED, that`s great. See the...
Even though i had isolation at the sensors and actuators to make doubly sure the PC also has been...
This high voltage white LED driver electronic circuit schematic is based on the NCP5021 IC...
Here`s an inexpensive electronic circuit that you can build to put in your Jack-o`lantern. It...
The A4988 driver IC has a maximum current rating of 2A per coil, but the actual current you can...
Designing and building an AM Broadcast Sucker-outer. The undesired AM broadcast signal is shunted...
The objective of this controller project is to have automatic block and switch control of five...
Circuit shown in Figure 3-189. Figure, SA controls switch; SBi is closing button; SBz to trip...
Contact resistance measuring circuit shown in FIG. It mainly consists of a constant current...
