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 circuit uses three easily available 555 timer ICs. All three work as astable multivibrators....
A small neon lamp is triggered into conduction by the telephone's ringing voltage, passes just...
The 741 has a maximum gain of 20,000, but the circuit is so designed that the IC"s gain is...
The circuit can use any general-purpose, low-offset, low-drift op amp, such as the OP-07. The...
This circuit can produce up to 1 W of audio power to drive a speaker or horn. When the CDS cell...
A block pinout diagram of the LS7220 keyless-lock IC is shown. The keypad must provide each key...
The first two are `passive` elements and op-amp is an `active` element. Also: the first two are...
Using the LT3692 dual current mode PWM step-down DC DC converter circuit with two internal 3. 5A...
To design and build a wireless transmitter that works over the FM frequency and allows the...
The meter has only one scale (0. 150) but this also used for 0. 75 and 0. 30. This is such a...
This circuit alarms whenever someone cross the Laser beam transmitted from a LASER. The output of...
I experienced faulty DS18B20 reads on my tank thermometers, probably due to my...
I took 22 used, octal, 6. 3-volt, 600mA, controlled-warm-up tubes (mostly 6SN7s) and 22 octal...
The modulator and the demodulator (pdf < 10 kb). For the easier tuning of the modem it could have...
Human reaction speed test circuit as shown in FIG. NAND gate D25, D26 and other components...
