When a new preview build of Windows 10 is ready to be released to members of the Windows Insider program, Microsoft's Gabriel Aul actually pushes a big red button to start the process. Now Aul has posted a way for anyone with a 3D printer to make their own Windows 10 Insider Preview update button.
Aul posted the files on the Thingiverse site, adding:
"This is the box for the button that we use to release builds to Windows Insiders in the Windows 10 Insider Preview Program. It uses an Arduino Duemilinove connected via USB, and the cutouts are for a large button, power switch, and speaker. Bottom plate is attached with small machine screws."
Of course, once you actually build the button, you won't be in actual control of when new Windows 10 preview builds are released, but you can imagine you have the same power and responsibility as Aul has in the comfort of your own home or office.
