Me and some of my friends wanted to have our own LCD displays that show cool and geeky stuff. So we did our own LCD's with some help of google.
This display shows my current Work Units (WU) that I have done in the SETI@Home project. |
 |
|
Not that many components to get this work. |
 |
|
A helping hand can come in place. |

Display in place. |

A good thing to keep in mind when you solder the 25 pin D-sub, is to put another d-sub in the connector. This prevents the pin's to move, because when you solder the pin's they get worm and they will probly melt the plastic that hold them in place. |
 |
|
I used this predrilled plated to put all components on. It's nice so you dont need to make your own circetboard. It may not be good looking, but it works. |
 |
|
From the paralell port (25 D-sub) you need 13 wires. I dident have a cable with 13 wires in it so I used an old TP cable or two to be exact. One TP cable contains 8 wires so if I take two I get 16 witch is more than enough. |

Here you can see the cabel coming in that is going to be attached to the 5V "hard drive cable".
The 5V goes in to the tape, and comes out as the green wire that goes up to the display.
The ground cable goes down to the corner in the bottom of this picture. |
