Snapmaker, The Modular & Multi-Functional 3D Printer
Snapmaker is a Kickstarter project with a lofty goal: to be the holy trinity for at-home makers by using detachable modules to convert between a 3D printer, a CNC carver, and a laser engraver. In retrospect, the idea seems almost obvious. All three devices need three-axis motors to work:...

snapVCC – A snap-on regulated 3.3 V/5 V power supply
by Mahesh Venkitachalam @ hackaday.io: I use 9 V batteries for a prototyping a lot of my electronics projects. I was inspired by the Sparkfun breadboard power supply board, and wanted to create something similar, but with a more convenient form factor for use with a 9V battery. The...
