Place the XLR jack in its hole and bolt it in place.

Carefully snap the LED into its holder.

Bend the wires for the audio jack so it will match its hole at the same time the USB port does. Carefully place them in their holes. If the audio jack is panel mount, screw on the mounting ring.

Put the bottom on the enclosure and screw it together.

Spray paint two coats of black enamel on the enclosure, and then one or more coats of clear enamel on the enclosure. Clear coat the bottom of the enclosure one extra time for extra protection.

Hot glue the standoffs to the bottom of the enclosure in the correct positions to match up with the protoboard.

Screw the protoboard into the standoffs.

Connect the USB cable again and ensure it still works.

The adapter is complete!

Now, go to the source folder and navigate to src/ti. Send the file DMXDEMO.8Xp to your TI-84 using your preferred linking program. If you don't know how to do this, read http://tiwizard.com/transferring-programs-to-your-....

Note that there is also a file called DMXDEMO0.8Xp. This is the source code and is not what you want right now.

Connect the link cable to your calculator and the adapter. Also connect the USB linking cable to your calculator and the adapter. Make sure the A end is connected to the calculator and the B end is connected to the Arduino. The Arduino will not accept the A end.
