Arduino DMX 512 Tester and Controller ENG

Control tool for testing and light show by the DMX-512 protocol, ideal for quick tests on fixed or temporary installations of lighting. This project arises from the need to have a portable system for rapid testing in lighting installations, without the need to install lighting consoles, interfaces or computers in environments outside, hostile or difficult to access.

Step 1: Licence

Step 2: Schematic

Step 3: PCB

We will have to print on a pre PCB negative press

Step 4: Simulator

We must run the simulator with the hex file or .elf

Step 5: Bill of Materials

Download

Step 6: Preparing the Phenolic Plate

We use a phenolic plate one face time, we reinforce the copper sandpaper water, thinner circularly

Step 7: Negative PCB

With Proteus send files to print a pre-press acetate negative (there is a PDF with the file)

Step 8:

Use and method photosensitive film

We use a paper laminator film to adhere perfectly pcb

Step 9: UV Light

Add a little water between the plate and acetate so that it does not move and apply UV light

Step 10: Revealed

Apply the ferric chloride are clean and ready

Step 11: We Perforate Plates

Step 12: Soldered Components

Step 13: Stripped to the Potentiometer Guide

phenolic drilled plate to put the potentiometer

Step 14: Keyboard Base

In the case of the girl plate, putting them headers weld the top, above the pins cut with sandpaper and water removed the excess

Step 15: Keyboard Mount

We add tape double tape para pegar el teclado a la placa

Here we encounter a detail, headers clogged with the flex of the keyboard, the cut (we consider for the next version)

Weld the headers that are under the keyboard and bend backward to connect the keyboard laterally

We put in place the keyboard on the LCD board, here's a detail, the base of the MAX485 am very attached to the keyboard, we force a little (we consider in the next version)
