Okay, here is the second part of the "No Warranty Void Hack." Same idea for a Pen Port Light (LED). The LED is a bi-color (red/green). By reversing the polarity when plugging the LED into the programming port you can change from red to green. The frosted lens gives a more diffused light.
I shaped a wooden plug - make a hole to mount the LED and run the wires - resister again is in line (470 ohm in this case). wires are twisted and shrink tube wrapped. See attached photos and the photos. More "scribbles" below and over at the Nikos' Fibonacci Spiral Challenge thread. These spiro-scribbles use some of Ken Gracey's Educator Course software.
