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.....

If you use great IC PCM2702 from BURR BROWN / Texas Instruments you can create a fully functional...
The chief advantage of this programmer is its ability to protect both the target and the PC from...
I Just finished my newest version of the "baby 10 sequencer". It has control voltage and gate...
The PWM controlled modified sine wave inverter circuit presented here uses just a single 4093 for...
The circuit shown here is a simple stereo FM transmitter that can transmit signals of high...
Here is a simple circuit that can be used to check the sound levels. The sound pressure meter is...
Introduction The MIC2290 is an internally compensated standard step- up Switching Regulator with...
I got frustrated and decided to hook it up to a 15v supply and jump R3 with a clip-on soldering...
A constant-current power LED driver circuit is shown in Fig. 1. Q1 is turned on by R1 and acts as...
Circuit operation principle of the device shown in Figure. Usually infrared light emitting tube...
Circuit shown in Figure 3-81. The circuit uses a transistor delay circuit to achieve start-stop...
