Stepper Motor

2012-01-20T15:21:00.001-08:00

A stepper motor is an electric motor that is brush-less and synchronous. It converts digital pulses into mechanical shaft rotations. Each rotation of a stepper motor is divided into a set number of steps, sometimes as many as 200 steps. The stepping motor must be sent a separate pulse for each step. The motor can only receive one pulse and take one step at a time and each step must be the same length. Since each pulse sent results in the motor rotating a precise angle, typically1.8 degrees, the position of the stepper motor can be precisely controlled without any feedback mechanism. As the digital pulses from the controller increase in frequency, the stepper motor movement converts into a continuous rotation, with the velocity of the rotation directly proportional to the frequency of the control pulses. A Stepper motor is widely used because of low cost, high reliability, high torque at low speeds and rugged construction that allows a stepping motor to be used in a wide environmental range.

Led UV Lamp

2011-04-17T11:56:00.000-07:00

I have some UV leds and I decided to make small UV lamp.

The lamp is made of 13 UV leds and 13 resistors of 470 ohms,

for each led I put one resistor.

Easy project to built and fun to play at dark room.

See the pictures :)

LA4182 Audio Amplifier 2x2 Watts

2010-10-14T11:48:00.000-07:00

It's not very powerful amplifier it's 2x2watts,but I make it because I love electronics and when i made something like this I fell good and proud because I made it.

It's very easy to built,there is no complicated parts,so do your amplifier and it will cost you approximately 4$.

Some pictures of my small amp and schematic are below.

LM317 Small Power Supply

2010-01-22T10:21:00.000-08:00

This is LM317 Small Power Supply.
The input voltage to the LM317 must be
at least 1.5v greater than the output voltage.
The output is adjustable between
1.25 and 13.5 Volts with a maximum
current limit of 1.5 Amps
A heat sink will be required for most
applications however.
On my picture you can see the heat sink.
Here is a schematic of LM317 supply.
