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.....

It is the essential continuity of circuits Sel 8 Sources and Up/Down Sel 8 Sources, but can work...
This project uses a four-point resistance measurement process also known as the Kelvin method....
I have few Kenwood TK-760G-1 transceivers (two-way radios) and they all were programmed to one...
had to rewire a boat trailer due to damaged wiring and lights. I`m using a standard 4 pole flat...
The circuit above is the canonical AC coupled common emitter amplifier which is typically used as...
This device is used to photograph moving objects by triggering a camera or flashgun when one or...
This Power Converter is used in LHC Machine to power superconductive magnets. It is located in...
This Fm rf ability amplifier has 2 transistors from Philips : BLV 10 and BLW 87. The 2 rf...
BFP640 used for 1575 MHz Global Positioning Satellite (GPS) Applications BFP640 is investigated...
The Muntz one-tube design can be considerably improved by adding an audio preamplifier stage....
This toy traffic signal uses a single low-cost hex Schmitt-trigger inverter IC (IC1a-IC1f) to...
This logic probe can be selected to operate on TTL or CMOS logic levels, depending on switch S1....
This battery-powered metal detector uses four exclusive-OR gates contained in the 4030 CMOS...
This circuit is a dual low/floating/high logic state detector which enables you to see the logic...
