And we are back again

I have move from TUT Pretoria Campus (Main) to Witbank (eMalahleni) Campus
 

and in the move some components of the winder mysteriously disappeared.... So I am almost setup again and only a few more tools/material to buy and we are building again.

Wire Winder continue 2

Some time has passed and the wire winder CAD is now finished and ready to be water jetted. The water-jet will only happen next year. Below is some pictures of the wire winder.

Winder Control Motors

Coil Winder Control Motors

A coil winder is automated machine that winders coils of different diameters on a given core. It will have a User Interface that will allow the user to select the type of coil to be winded and the amount of turn around the core.

On the image above is a Wantai stepper motor which is powered by 24 V DC and a current of 3.0 A. It is driven by a  Single Axis Controller 3 A TB6560 Stepper Motor Drivers Board that allows the control of the steps(rotation) by a 5 V input signal and the control of the direction by a HIGH(5V) for clockwise and LOW(GND) unti-clockwise . The stepper motor would be would be responsible for controlling the winding process with the condition given by the user.

On the image above is a 3-phase induction motor with a supply of 220 V AC  and a variable motor speed driver.that will control the start,forward and reverse of the motor. The motor would be responsible for rotating the drum so the coil can be released to the stepper motor. The motor must be set on the speed required for the winding process to be completed correctly.

So far all the individual testing have been done and have shown good results and implementation of the whole winding machine is still in process.

pcDuino Setup and basic configurations

 pcDuino  Board

pcDuino is a mini PC platform that runs PC like OS such as Ubuntu and Android ICS. It outputs screen to HDMI. Moreover, it has hardware headers interface compatible with Arduino (TM) and It also provides a JAVA platform for application development.

We have have configured all the board and connected all the necessary connections, to setup a development environment. The board will be the supper brain of the waterfall project as it will be responsible for the processing of the user interface and controlling the required hardware components of the project.

Thank You

Waterfall Project User Interface (sample)

Waterfall Project User Interface (sample)

The waterfall projects provides the user with an interesting graphical user interface whereby the user can  navigate, brows and select an image of choice from the file storage.

The graphical user interface is 60% complete but will provide features such as:

- Selecting an image from file.
- Displaying image of the Graphical User Interface (in progress).
- Display binary image on the user interface.
- Send the binary data to be processed and displayed on the waterfall display(in process).
- Clear binary display to allow a new image selection.
- Exit the Graphical User Interface after having fun with your image display.

New mind blowing features are still COMING SOON... 

Hope I got your mind's focused on the Waterfall Project.
Thank You

Setting up the security camera

                                            Setting up the security camera for Work Station

The aim of the task was to set up the camera so that me and my co-workers could work in a safe environment whereby we would be sure that our equipment and belongings are well looked after.

The first step was mounting the camera on the wall at an angel that will provide the view of the entrance of the work space, as well as an 80% view of the work space.

The next step was to test power supplies in order to get a 12V DC supply  for both the display(Monitor) and the camera.
                                                 
                                                           

The last step was to mount the display on the wall in Mr AC De Villiers (Admin) office so he can monitor the work space in-terms of giving access to personnel and security reasons. The camera was well installed and was working accordingly.

                             

The task was well completed with the assistance of my co-workers Mr  DW  Adebayo and Mr KZ Motshoane.

Thank You.

Powering the work stations

                                                    Stetting Up Power Rails

                               

We had limited power in our work station, to plug in most of the equipment we were required to use to complete the Waterfall project. As a Power engineer student I decided to take a safe approach of setting up the power rains under the work station tables to keep wires from running all around the work station, so my co-workers and I can be safe if any electrical failure occurs.

Making sure that all sockets connections are done correctly to provide a well safe environment for everyone to use.

Thank You.
