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 is a mini strobe light. NE555 is used as a self oscillator. The width of output pulse is...
These are two - easy to build - relay-based alarms. You can use them to protect your motorcycle -...
Transistor Q1 can be a 2N2222(A), 2N3904, NTE123A, ECG123A, etc. Not critical at all. It acts...
This circuit is operating the room illuminates. The basic component of the circuit is a IC1...
This project uses the 1.2v rechargeable battery and solar panel from a Solar Garden Light. These...
If R, the sensor matching resistor, is equal to the "dark" resistance of the cadmium sulfide...
The LM1812 is a complete ultrasonic transceiver on a chip designed for use in a variety of...
Improving the Canon 5D Mark II audio so that it can produce usable production audio. The first...
Trigger programming with its build-in pushbutton. The solution I came up with was to add a tiny...
This is the first circuit I created. Working principles are described in the "Basic Info" page....
applications in the 2400 MHz ISM band. This two stage RFIC amplifier is off-chip matched to...
Undervoltage release is long-term work, when the power supply voltage drop in the operating...
Circuit operation principle of the device shown in Figure 11. Power outages are frequent thing,...
