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.....

This electronic speed control (ESC) for brushed motors combines the features of two of my earlier...
Our CONTINUITY TESTER gives an audible indication of continuity between the probes so you can...
The 2 pushbuttons = S1: Start/Pause. S2: Stop/Reset. If you want to play your message, put S3 at...
A typical circuit at 20 MHz is shown. The crystal, which has an internal series resistance Rs of...
This simple amplifier does sound good quality Power output about 10 - 14 Watts with Supply...
FAN4810 work, to the average current, electric current of front continuously CCM The work pattern...
If you`ve got a Squeezebox then you`ve probably got an amplifer to go with it. Having to get up...
With the connections made in this order on the connector it will not matter if the connector is...
This design adapts such a high voltage flash for use on a low voltage camera by using an...
This is where truthfully you need to migrate to pic micro and possibly look at compilers such as...
This UHF amplifier circuit electronic project can be useful in situations where the TV signal is...
This project is a simple 12V to 220V modified sine-wave inverter using 555 timer IC and CD4017...
- The use of a number of integrated circuits rather gated automatic lighting circuit device...
Compilation dial phone numbers with 15 commonly used libraries (plus number dialed) are stored...
