Counting from rollout of the first 747 in 1968, that's ~54 years of building 747s.

Hacking on a trio of cheap PC case fans so #WS2812 #NeoPixel LEDs embedded in each hub can be controlled using #Pixelblaze by @ledmage. Test here is running my X/Y/Z-axis sweep program to verify 3D coordinate map.
I wrote up my project details and posted them to Pixelblaze forum. forum.electromage.com/t/pixe…
