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.....

Well, it's pretty much a PAiA preamp - usual input circuity followed by one half of dual op-amp...
This programmer was designed in view of to be flexible, economical and easy to built, the...
This circuit shows how to cascade counters and retain correct leading zero blanking. The NAND...
This TMOS VCO operates in push-pull to produce 4 Wot 70 MHz. It consists of two MFE930 TMOS...
This system contains an IR transmitter, an IR receiver/RF transmitter, and an RF receiver/alert...
For all electrically conductive Fluid or liquid level measurement, this single-chip circuit is...
Using a K-12 tube amp with a NAD C542 CD player, there is no need for a buffer or line level...
Although my circuit allows for different combinations of input voltages (Vin) and output voltages...
Make a sound card is no more a complex issue. If you use great IC PCM2702 from BURR BROWN / Texas...
The OPB350 series liquid Sensor is designed to work with 1/16 [1. 6mm] 1/8 [3. 2mm], 3/16 [4. 8...
C1=1000 Micro Farad aluminum electrolytic capacitor (For loads less than 100mA you can sustitute...
A very lab adjustable power supply that can provide an output voltage between 0 and 60 volts can...
A notch for a narrow frequency band of a few per cent or even less normally requires...
