Nice project! Have you thought about using other LED colors for the outer ring? This has some spaceship docking guide vibes [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-183f8c79-052e-4770-8fe0-d0d3e9f4b109/contentimage_5F00_1.png:16:16]

Very cool addition to your project. It seem to work very well.

Have you considered trying to use the LEDs to detect the laser? I've never tried it myself, but I've read that an LED can also act as a photodiode.

I'm not sure how easy it would be to switch between being used to emit and detect light in the same project, or what LEDs would best detect a red laser pointer though.

I recognise that 3D printer software from my own UP Plus. A great printer - I won it on Instructables back in 2012 and it's still going strong.

Hi Dubbie,

Great project! I wonder if it could be extended to create a bigger round led board, with few more LDRs, to play a sort of laser-darts!
