This week, Hackaday’s Elliot Williams and Kristina Panos met up over the international tubes to bring you the latest news, mystery sound results show, and of course, a big bunch of hacks from the previous seven days or so.Regarding Hackaday Europe, we announced the last round of speakers and opened up the workshop ticket sales. In other news, the Green-Powered Challenge has wrapped, and judging will begin quite soon.On What’s That Sound, we can score another one for Kristina, which brings her record to approximately four wins and sixty-eight losses. She knew without a doubt that this was a guillotine paper cutter, probably because she recorded the sound herself. Hey, don’t take this away from her.After that, it’s on to the hacks, beginning with a really cool laser-powered mist-and-mirrors multi-view display, a robotic drawing assistant of questionable utility, and a new slicer that enables horizontal overhangs without supports.We also look at a trackball 3D controller, a 3D-printed pinball machine, and a good way to kill humidity sensors with humidity. Finally, we’re both shocked to learn that we’ve been on GPS mk. II for some time now. But then once we get over that, we talk tablets and their usefulness, or lack thereof.Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments![podcast go here]Download in DRM-free MP3 and savor at your leisure.Where to Follow Hackaday PodcastPlaces to follow Hackaday podcasts:iTunesSpotifyStitcherRSSYouTubeCheckout our Libsyn landing pageEpisode 368 Show Notes:News:Hackaday Europe: Last Round Of Speakers, WorkshopsWhat’s that Sound?Congrats to [Primary Schoolteacher’s Best Friend After Laminator], who knew this was a classic guillotine paper cutter.Interesting Hacks of the Week:Mist, Mirrors, Laser : Multi-view 3D ProjectionVolumetric Display With Lasers And Bubbly GlassPenPal, A Robotic Drawing AssistantNew Slicer Enables Horizontal Overhangs Without SupportArc Overhangs Make “Impossible” 3D PrintsPayphone Tag Is Australia’s New National SportA Trackball 3D ControllerA Simple 6DOF Hall Effect ‘Space’ MouseA DIY CAD Mouse You Can Actually BuildOld 3D CAD Mouse Gets New Lease Of LifeSpaceMouse Destroyed For ScienceCan You 3D Print A Pinball Machine That’s Fun To Play?Quick Hacks:Elliot’s Picks:A Guide To CubeSat Mission And Bus DesignHow To Kill Humidity Sensors With HumidityDigital Signal Processing On The Pi PicoKristina’s Picks:Audio-Forward Case Mod Of Classic 90s Portable TVTime Frog Color Is A Game Boy Color On Your WristThe Challenges Of 3D Printing Reliable SpringsCan’t-Miss Articles:The GPS III Rollout Is Almost Complete, But What Is It?Ask Hackaday: Do You Need A Tablet?
