10 Years ago I decided to upgrade my (Jewel Green) Supra interior lighting to LEDs. At first I did those poorly using bare LEDs strung across the button rows. They had a tendency to burn out quickly due to vibration, etc. So then I experimented in making my own discrete circuit boards. This took forever to make as I had to lay all the circuit paths and then Etch them.
Then I decided to have them professionally made. But the issue with these were I had to individually cut each item out with hole saws. Again, this took forever. So I asked my son, Marshall, to see if there C&C machine at his work could possibly cut them out. So this was a huge time saver. Like 50% less time.
Here is a video of them being cut out: http://97supraturbo.com/LEDs/20131127_100747.mp4. This video is showing the HVAC round boards and all the Instrument micro needle LED boards being cut.
Here are the pictures of all of the induvial boards. (newer versions in green)
