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 circuit charges a 9-V battery at about 30 mA per input ampere at 0.4 V. Ul, a quad Schmitt...
When the 14B-12B pair opens, 12B is connected to Al's summing point via 13B. The sensor now...
The circuit is intended for 117 Vac ± 50 Vac operation, but can be easily modified for higher or...
Transistor Ql of the headset amplifier circuit amplifies the 30 mV signal, that would have gone...
This decade box can be set for any resistance value between 10 and 11.1 in 10- stops. A switch...
If you send a DC voltage signal to carry the information for a long distance, then the signal...
This article is about a simple 5 channel radio remote control circuit based on ICs TX-2B and...
An analog output for my Arduino. The most common way to build a DAC is to use a R-2R ladder...
This electronic liquid detector circuit diagram is based on the ULN2429A monolithic bipolar...
Q1 and Q2 form an ALL-ON ALL-OFF circuit that in the off state draws no significant current. P1...
This low-cost burglar alarm employs a 12V strobe light and a truck reversing horn as the visible...
Circuit 90s common recorder head amplifier circuit, the choice of ultra low noise precision op...
FT245BM typical hardware circuit as shown in FIG. This circuit uses bus-powered mode, while using...
