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 instrument used to measure battery capacity. The battery may be charged to any current in the...
The analog input is fed into the span resistor of a DAC. The analog input voltage range is...
The heart of the electroscope is the two junction FETs Ql and Q2 connected in a balanced-bridge...
Used on an amateur or experimental radio beacon, the above ID circuit will generate any callsign...
With a magnetic compass ensure that both pickups have a South polarity on the top of the pickup....
As everyone knows, any closed loop system is unit gain to noise temperature ratio l in the gain...
With an integrated voltage regulator connected reverse to a mini drill can be adjusted speed...
A PIC is a Programmable Integrated Circuit. It is the big black ractangle on our breadboard. The...
This light alarm schematic circuit is designed using some common electronic parts, as you can see...
This circuit is similar to the "Fading Red Eyes" circuit (in the LED section) used to fade a pair...
Beware that not all transistors share the same terminal designations, or pinouts, even if they...
Having two sets of PWM signal generating circuit within NCP5201 chip, a set of output pins and the
M5227P is the application circuit, for graphic equalizer, its control curve is always logarithmic...
Circuit shown in Figure 3-189. Figure, SA controls switch; SBi is closing button; SBz to trip...
