Join Hackaday Editor-in-Chief Elliot Williams and Managing Editor Tom Nardi for a recap of all the best tips, hacks, and stories of the past week. We start things off with an update on Hackaday’s current slate of contests, followed by an exploration of the cutting edge in 3D printing and printables. Next up we’ll look at two achievements in detection, as commercial off-the-shelf hardware is pushed into service by unusually dedicated hackers to identify both dog poop and deep space pulsars (but not at the same time). We’ll also talk about fancy Samsung cables, homebrew soundcards, the surprising vulnerability of GPS, and the development of ratholes in your cat food.

But ironically, this homage features a critical piece that’s actually not made of wood. The 77’s pickup pattern was cardioid, making for a directional mic that picked up sound best from the front, thanks to an acoustic labyrinth that increased the path length for incoming sound waves. [Frank]’s labyrinth was made from epoxy resin poured into a mold made from heavy paper, creating a cylinder with multiple parallel tunnels. The tops and bottoms of adjacent tunnels were connected together, creating an acoustic path over a meter long. The ribbon motor, as close to a duplicate of the original as possible using wood, sits atop the labyrinth block’s output underneath a wood veneer shell that does its best to imitate the classic pill-shaped windscreen of the original. The video below, which of course was narrated using the mic, shows its construction in detail.
