Lighted circle straight drilling aid - GIF

As Marv posted - this is a project on Indiegogo by a company called BullsEyeBore

They anticipate this will sell for $139 in August

I think you could make your own of this. It uses multiple lasers (cheap cat toy laser pointers are 6 for $11) and magnet(s) to hold the device to the drill chuck, and a humk of plastic (3D printable)

Also, it has a power switch. A kewler design would use a centripetal switch so it turns on when the drill chuck spins.
