A Comprehensive Look at FDM Supports
When we first started 3D printing, we used ABS and early slicers. Using supports was undesirable because the support structures were not good, and ABS sticks to itself like crazy.

MEMS Teardown and Macroscopic Models
There is a bit of a paradox when it comes to miniaturization. When electronics replaced mechanical devices, it was often the case that the electronic version was smaller. When transistors

PCB Makes 7 Segment Displays
Of course, there’s nothing unusual about using 7-segment displays, especially in a clock. However, [Edison Science Corner] didn’t buy displays. Instead, he fabricated them from a PCB using 0805 LEDs

The Curved Nature of Time Clock
While we’re told that space-time curves, we aren’t sure that was what [andrei.erdei] was going for when he built a great-looking curved LED clock. The LEDs are courtesy of a

Electromagnetic Mechanism Makes Reconfigurable Antenna
Antennas are a key component to any RF gadget. But antennas often only perform well over a narrow band of frequencies. For some applications, this is acceptable, but often you
