The NCP5810D is a dual ’output DC/DC converter which CAN generate both a positive and a negative voltage. The device is optimized for powering modules such as AMOLED Display drivers where very good output voltage accuracy and regulation, signal integrity and.... -
The AS3636 is a highly integrated Photoflash charger including IGBT driver, inductive DCDC boost autofocus/ video LED driver, an indicator LED driver and it includes system level ESD protection and a .... -
MOC3020M Integrated Circuit. I would love a LED to tell me when each cap is charged but I have no idea how to do that or where to put in the circuit, I have a bucket load of 5v LEDs so making use of some would be great. I have Circuit maker but dont have a.... -
This circuit used to come as a kit from a surplus supplier, but probably isn`t available anymore. It shows a few novel concepts such as using a 555 as a pulse width modulator (PWM), and series/parallel camera flash transformers. WARNING: This circuit is.... -
This discussion covers 3 different Xenon flashing circuits from disposable cameras. From them, you will learn circuit tricks that have NEVER been shown in any theory book.The first circuit covers 6 BUILDING BLOCKS.You will need an old disposable Flash Camera.... -
The size of the photoflash charger circuit is greatly simplified and reduced by Texas Instrument (TI) TPS65552A. A photoflash capacitor charger based on this.... -
This project generates 350V DC and stores the voltage in a large electrolytic. This voltage will not kill you, but will deliver a nasty SHOCK! For this reason, the project has a great benefit. It will teach you to work very carefully on equipment with high.... -
Two transistor oscillator generates pulses at about 500 Hz for step-up by 300-mA filament transformer T1 (Radio Shack 273-1384) to charge storage capacitors C2 and C3, which are 250-V electrolytics. Simultaneously, C4 is charged through R2. After allowing.... -
This page exists as a repository for items you may need to consult from time to time, such as identification guides, diagrams, etc. There is also a project in the works to make the S130 fiche easier to navigate and find what you`re looking for. You`ll need....

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.....
