Ep 172: Frickin’ Laser Beams, Squishy Stomp Switches, and a Tiny but Powerful DIY Loom

Join Hackaday Editor-in-Chief Elliot Williams and Assignments Editor Kristina Panos for a free-as-in-beer showcase of the week’s most gnarly but palatable hacks. But first, a reminder! Round 2 of the 2022 Hackaday Prize comes to an end in the early hours of Sunday, June 12th, so there’s still enough time to put a project together and get it entered.

This week, we discuss the utility of those squishy foam balls in projects and issue the PSA that it is in fact pool noodle season, so go get ’em. We drool over if-you-have-to-ask-you-can’t-afford-it 3D printers with staircases and such, and wonder why breadboard game controls didn’t already exist. Later on we laugh about lasers, shake the bottle of LTSpice tips from [fesz], and ponder under-door attacks. Finally, we’re back to frickin’ laser beams again, and we discover that there’s a fruity demoscene in Kristina’s backyard.
