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 "LCD2LPT with Lirc" circuit is the compilation of two circuits found on the net on a single...
This electronic lock can be used with any type of iButtons you may already have, since the only...
This is door knob touch alarm for your home security purpose. The alarm will be activated when...
This audio amplifier designed uses two LM3886 per channel, in parallel circuit, based on the...
Going camping nowadays involves taking lots of electronic equipment whether for day to day...
The approach you have shown would dissipate (12V)(3A) = 36 watts. This is quite a lot of...
Have already gone through 3 stages till a few days ago in the developing of street lamp control...
The biggest issue is that the RDS_on of the used MOSFETS is, driven with 5V gate voltage, too...
This decibels meter circuit responds for sound pressure levels from about 60-70 dB(Decibels)....
Solar energy has now become a popular alternative for the production of electricity. Here is a...
Here is a very simple circuit that can be used for testing Zener diodes. The IC1 NE555 is wired...
Based on the famous AT89C52 microcontroller, this 500 Khz frequency-Meter will be enough to trace...
If your stereo amplifier does not have an input for a record player, you should use this circuit...
Had bought this EDE702 some time ago, and a LED-backlit LCD character display. After buying the...
