DMX-MiniController

Handheld DMX controller

[!WARNING]

The image’s assemble has a mistake. DMX output should be XLR female connector, but it’s male.

Step of production

At first, build a circuit.

Schematic is below:

[!NOTE]

You can see PDF of the schematic in schematic/. Also KiCAD Eeschema .sch file is contained.

Next, upload firmware to Arduino nano on the circuit.

Firmware source is in DMX-MiniController_Arduino. Open it by Arduino IDE, then upload.

[!NOTE]

Actually, the source quality is not well (e.g. using many global variables). But I will not improve them. It’s a memory of my old work.

It’s ready.

Usage

• Write switch
  • Apply value to current channel
• Channel – / - (decrement) switch
  • Decrement current channel
  • -- for -10, - for -1
• Channel + / ++ (increment) switch
  • Increment current channel
  • + for +1, ++ for +10
• Value knob
  • Set value to write

Example steps of set channel 4 value to 100:

1. Click Channel+ switch, then set current channel 4
2. Rotate value knob, then set value 100
3. Click Write switch

By following the step, the LCD view will be below:

Knob part 3D model and drawing for value knob (variable resistor). But…

• The drawing (Knob.pdf) has not enough dimensions
• I can’t remember the model number of variable resister

old-reference

I wrote a usage guide with LibreOffice writer for printing.

README.md describing containing files in the directory (at that time, it was not a Git repository).
