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.....

There is no PCB since there are no components to mount on one. the object was to create a source...
The SN75604, with input control logic but requiring only one supply rail, can be used in the...
A shows a COR/CAS circuit for repeater use. CR1 is a silicon diode. 2 may be any relay with a...
In order to display polar quantities (magnitude and direction of a received radio signal), a...
Following a highly successful Kickstarter project and over a year of development, HexBright,...
This fm transmitter circuit is very simple and it has a acceptable transmission. The signal...
This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main...
I have an automotive relay (from a scan of a workshop manual I`m afraid) which is rather more...
The tuner is programmable via I ²C-Bus and provides a FBAS signal at its output. There is also...
The headlights and photo cells will face the ground, so I find it easiest to imagine that the...
All of the above would be internal hardware issuesa. Still, there is a possible fix; though not...
The constant current charging circuit which is composed of the three-port voltage stabilizer is...
It is possible to build a three-phase sine-wave oscillator using just one UAF42 state variable...
The original firmware is usable on the amateur radio bands, but is not very convenient to use....
AC solenoid DC circuit operation DC operation AC contactor circuit on the same principle, but the...
Dispenser (Aucma) temperature detection control circuit It shows the dispenser (Aucma)...
