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 circuit in Figure 2 shows a 16-channel, AMI-encoded RF transmitter for data rates as high as...
200W Lamp Flasher is used to flash lamps, bulbs and halogen lamp to give your product that...
When the phototransistor is stroken by IR light it conducts and the voltage between the 1Mohm...
The amplifier uses a grounded grid circuit with either the Eimac 3CX1000A7 or 8877, ceramic/metal...
Above is a schematic diagram of an LM741 light/dark sensor circuit (from the excellent 741 Op-Amp...
Our car radio has the annoying habit of forgetting what part of a CD it was playing when you turn...
The Philadelphia, PA based Maker/hacker group Hive76 developed a tiny serial terminal using a TI...
Using the LTC3810-5 synchronous step-down switching regulator controller can be designed a very...
To know whether it is freezingyou only need tomeasure the temperature. This has to be done...
This scheme applies amplifier OpAmp LM301 to awaken square wave that is simple. LM301 applies...
The PA output Pi section consists of 2 variable Cs (20 - 120pF and a second (home made) 50 -...
With two light barriers closely positioned one after the other it is possible to establish in...
AD594/595 can also be configured to Celsius, the circuit shown in FIG. This time should be IN +,...
As shown for the capacitor, the frequency detecting circuit transistor line. Can be converted by...
