# Ep091: Louisville Exploder, Generating Japanese Joinery, Relay Retrocomputer Rally, and Chop the Robopup - Show: [Hackaday Podcast](https://hardwarepodcasts.com/podcast/hackaday-podcast) - Published: 2020-10-30 - Length: 57m - Episode: 91 - Page: https://hardwarepodcasts.com/podcast/hackaday-podcast/2020-10-30-ep091-louisville-exploder-generating-japanese-joinery-relay-retrocomputer-rally - Listen: https://hackaday.libsyn.com/ep-091-louisville-exploder-generating-japanese-joinery-relay-retrocomputer-rally-and-chop-the-robopup ## Summary Hackaday editors Mike Szczys and Elliot Williams discuss a week of hardware hacks, including Shane's 'Louisville Exploder' which uses explosive blanks to break a baseball home run record, and Miguel Ayuso Paria's 'Chop' robot dog built with Raspberry Pi and Arduino components. They also cover George Foote's relay-based retrocomputer, Maria Larson's 'Sugite' software for generating Japanese wood joinery, and Tom Stanton's Hall effect flight simulator controls. The episode highlights the community's engagement with open-source hardware, from 3D-printed robotics to complex electromechanical builds. ## Chapters - [0:01](https://hardwarepodcasts.com/podcast/hackaday-podcast/2020-10-30-ep091-louisville-exploder-generating-japanese-joinery-relay-retrocomputer-rally#t=1) Introduction: YouTubeDL DMCA Takedown and Podcast Host Switch -
