This is a simple circuit which outputs a voltage which is more than the input. This could be used to power 12v or 9v devices from a 6v system, or even 6v devices from a 1. 5v battery (see below). This circuit uses bog standard parts, without requiring a magical `do-it-all` IC. You can make an ultra simple 1. 5v to 9v regulated stepup converter by us

ing a TL496 IC, a coil and a capacitor, but that`s not so much fun if you want to experiment. I`ve already built a TL496 based circuit so I started doing web searches for something that I could make that would allow more fiddling and a wider range of applications. The only unusual component in this circuit is the coil (L1). I am not going to give you instructions on how to wind "the" coil because so many different types work with this circuit. Even a small DC motor works! These are the coils I have tried so far: The 60 turn coil gave the highest output voltage but the current draw without any load was already 40mA, probably because its DC resistance is very low. The motor and hookup wire coil gave reasonable performance. The solenoid seemed to give the best overall performance. The values shown for R1 and C1 will cause oscillation at about 40KHz. You should experiment with these too as different coils may perform differently at different frequencies. When I decreased R1 to 130k the frequency increased to about 180KHz and the output voltage increased by a few more volts. Make sure C2 is rated for the output voltage. I used a 47uF 50v electro because it`s what I happened to have lying around. A higher value may give better performance with less ripple on the output. The first setup of this circuit used the solenoid and a 9v battery. The output was around 41v with no load. With the 60 turn coil, it exceeded 80v! (With a 50v...
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.....
