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 amplifier was born out of a need to use two sets headphones with my computer's sound-card....
Voltage is applied to the chip via pins 14 and 7 so that when power is applied to the project,...
Figure A shows the circuit of a direct-trigger timing light. The trigger voltage is -taken from...
A 1-V amplitude pulse triggers SCSl, but has insufficient amplitude to trigger SCS2. A 3-V input...
The greatest sensitivity is achieved if R1 is approximately equal to the probe resistance. The...
This project is based on the parametric equalizer proposed by Elektor in the late 80s or early...
Tape isolate single-phase PFC that DC/ DC vary make up, make up two cable, PFC of three-phase,...
The proposed remote control circuit idea can be used for controlling any electrical gadget within...
The chips that are termed "working well" yield about 300 mV under the beam from a laser pointer...
This design was created at the request of my father. It is designed to operate a 240V a. c....
The 230 V, 50 Hz is step downed using voltage transformer and current transformer is used to...
The circuit was deliberately designed using no ICs and in a rather old-fashioned manner in order...
Connected to a burglar alarm or fire alarm in the event of making phone calls playing voice...
Sections of RS339 quad comparator each drive LED to give indications of four different input...
This is a general purpose remote control project with using programmable PIC microcontrollers....
1C foot VIII made a number of training device, from the trigger terminal CI. f-off positive input...
As shown in FIG grounds PGA203 and isolation amplifier IS0102 constitute isolated programmable...
