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 power output of most of these circuits are very low because no power amplifier stages were...
The sensing circuit rapidly disconnects the battery voltage and load whenever the voltage drops...
The variable voltage regulator lets you adjust the output voltage of a fixed de power supply...
The fan employed is one of the new electrostatic type which is very reliable, because it contains...
When an inverter is biased with one resistor from its input to output in the range of 100 KOhmhm...
Figure 1 exhibits the circuit with the muscular stimulator. IC 7555 is actually wired just as one...
Choose a free schematic drawing software, and like the way these two look. I`ve read related...
The very small DC voltages at the output of the diode detector are difficult to amplify...
Here is the circuit diagram of superb mini audio power amplifier, That can be power with 4. 5...
The ADUC816 is a complete smart transducer front-end, inte- grating two high-resolution...
The +/- 3 dB point for the treble is about 2, 5 KHz, with about 12 dB boost/cut at 10 KHz....
There are other display methods than the original 8 led frequency counter has. They are perhaps...
The following is a translation of a section from the first book of the 3 part series "Die RG¶hre...
[The following circuit is adapted from battery monitors and testers published in The...
This stage adds the TX Mixer to the board and provides the modulation of the Dividers` output...
4 ~ 20mA current transmitter circuit from the MAX1459 configured as shown in FIG. The PGA output...
As shown in FIG frequency power supply noise filter circuit. The circuit is a double-T filter,...
Circuit shown in Figure 3-132. The line is automatically round-trip, plug braking circuit. In...
