Keeping Time with Blinkenlights

If we’ve learned anything over the years, it’s that hackers like weird clocks, and they love packing as many multicolored LEDs into a device as is humanly possible. Combine both of those concepts into one project, and you’ve got a perfect storm. So as far as unnecessarily complex timepieces go, …read more

Rock ‘n Roll With 3D-Printed Tonewheels

What can you do with ferromagnetic PLA? [TheMixedSignal] used it to give new meaning to the term ‘musicians’ gear’. He’s made a proof of concept for a DIY tone generator, which is the same revolutionary system that made the Hammond organ sing.

Whereas the Hammond has one tonewheel per note, …read more
