Working for an electrical suppliy power company in a educational proyect I made a model of a High voltage switch using a crouzet XD26 PLC

High voltage switch model with PLC

This is a simple program in a CNC that makes a rectangle

CNC simple program

I had a problem with a whashing machine that burned out his control
Then I programmed a PLC to substitute the washing machine control
And here it is!

PLC controlled Washing machine

This proyect is for making a robot using raspberry pi and a usb for butia and garbage
It has a traction DC motor and a stepper motor to turn
It can be controlled via a webpage and consequently also using a smart phone
It is compatible with an usb4butia I had .The usb4butia has sensing capabilities like proximity and light sensor

Raspberry pi Robot controlled by web page

A velocity control of a stepper motor´s velocity was done.The control can change the speed and make the motor spin in ccw,cw and with a stop posibility.This control can be done by two ways
1) By a potentiometer and 3 switches
2)By a keypad

A demostration of the proyect working can be seen in this video

Velocity control of a bifasic stepper motor using arduino

A design of a square wave sinusoidal from http://danyk.cz/menic230_en.html was modified to be a sinusoidal inverter using a 555 ic
450W could be obtained with a voltage of 100V and the minimum load recommended is 130W because this system is open loop control
Future design will control the duty cycle in order to regulate the output voltage
You can see a video demostration here

Noise reduction in dc-dc voltage mode using sigma delta

Guillermo Genta

The aim of this paper is to reduce switching noise of voltage mode DC-DC converter using sigma delta a modulator insted of classical ramp-PWM In order to get the characteristics of the sigma delta modulator ,first of all a static curve is obtained .To reduce swithcing power there exists a trade off between noise and stability of modulator.In this direction a stability of the non linear sigma-delta.It is needed to modell the sign element using an aproximation given by slottine
