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 circuit is very basic to build. To open a lock which is connected to the K1 Load, you must...
The MC1596/MC1496 makes an excellent SSB product detector. This product detector has a...
The Arduino Internet Gizmo is a USB, Arduino, and RFID device for web surfing. The gizmo works by...
This ISP Programmer can be used either for in-system programming or as a stand-alone spi...
FIG. 1 (A) illustrates the circuit diagram of one embodiment of the fluid level detector of the...
The designer of this circuit had fitted two (waterproof) loudspeakers in his bathroom and...
When entering the power supply 9-volt circuit IC1 number LM386 amplifier IC size is 300-800 mW,...
The metal detector circuit shown here must represent the limits of simplicity for a metal...
This simple micro-control circuit controls a servo motor according to a 3-state switch. A servo...
This circuit is similar to the one above but uses positive feedback to get a little more...
The design is based on the TubeHobby and is the power supply used in their NC2. I built this very...
The high voltage electrolytic capacitors in valve equipment tend to deteriorate if the equipment...
The following schematic shows the JFET- Bipolar Cascode Circuit Diagram. The JFET- Bipolar...
AC welder is intermittent operation, the intermittent load power consumption during the period up...
Circuit shown in Figure 3-108. SB3 for the forward button; S Island reverse button; SBi as low...
