Hackaday Podcast 089: 770 Potato Battery, Printing Resin Resist, And No-Internet Video Chat

October 16, 2020 by No comments

Hackaday editors Mike Szczys and Elliot Williams weigh the hacking gold found across the internet this week. We can’t get over the epic adventure that went into making a battery from 100 pounds of potatoes. It turns out you don’t need Internet for video conferencing as long as you’re within a coupe of kilometers of everyone else. And move over toner transfer method, resin printers want a shot at at-home PCB etching. We’ll take a look at what the Tesla selfie cam is doing under the hood, and lose our marbles over a ball-bearing segment clock that’s defying gravity.

Hackaday Podcast 088: Flywheel Trebuchet, Thieving Magpies, Hero Engines, And Hypermiling

October 9, 2020 by 2 Comments

Hackaday editors Elliot Williams and Mike Szczys riff on the hardware hacks that took the Internet by storm this week. Machining siege weapons out of aluminum? If they can throw a tennis ball at 180 mph, yes please! Welding aficionados will love to see the Hero Engine come together. We dive into the high-efficiency game of hypermiling, and spin up the polarizing topic of the Sun Cycle. The episode wouldn’t be complete without hearing what the game of Go sounds like as a loop sequencer, and how a variable speed cassette player can be abused for the benefit of MIDI lovers the world over.

Hackaday Podcast 087: Sound-Shattering Gliders, Pressing Dashcam Buttons, And Ratcheting Up Time

October 2, 2020 by No comments

Hackaday editors Mike Szczys and Elliot Williams dish up a hot slice of the week’s hardware hacks. We feature a lot of clocks on Hackaday, but few can compare to the mechanical engineering elegance of the band-saw-blade-based ratcheting clock we swoon over on this week’s show. We’ve found a superb use of a six-pin microcontroller, peek in on tire (or is that tyre) wear particles, and hear the sounds of 500 mph RC gliders. It turns out that 3D printers are the primordial ooze for both pumping water and positioning cameras. This episode comes to a close by getting stressed out over concrete.

Hackaday Podcast 086: News Overflow, Formula 1/3 Racer, Standing Up For Rubber Duckies, And Useless Machine Takes A Turn

September 25, 2020 by No comments

Hackaday editors Elliot Williams and Mike Szczys peruse the world of hacks. There was so much news this week that we lead off the show with a rundown to catch you up. Yet there is still no shortage of hardware hacks, with prosthetic legs for your rubber ducky, a RC cart that channels the spirit of Formula 1, and a project that brings 80’s video conferencing hardware to Zoom. There’s phosphine gas on Venus and unlimited hacking projects inside your guitar. The week wouldn’t be complete without the joy of riffing on the most useless machine concept.

Hackaday Podcast 085: Cable Robots Two-Ways, Cubic Raspberry Pi, Plastic Wrap Kayak, And Digging Inductors

September 18, 2020 by 1 Comment

Hackaday editors Mike Szczys and Elliot Williams take a look at all the hacks from the week that was. We think we’ve found the perfect tentacle robot, and its matching controller is also a tentacle. An unrelated project uses the same Bowden cable trick as the tentacle controller to measure deflection. If you’re more of a material-science geek, refining black sand to make your own inductors is a fascinating hack. And we wrap up the episode talking SSH keys and buses that go off road, but not in the way you might think.

Hackaday Podcast 084: Awful Floppy Disk Music, Watching A Robot Climb Walls, A Futuristic Undersea Lab, And Inside A Digital Pregnancy Test

September 11, 2020 by No comments

With Editor in Chief Mike Szczys off this week, Managing Editor Elliot Williams is joined by Staff Writer Dan Maloney to look over the hacks from the last week. If you’ve ever wondered how the Beatles sound on a floppy disk, wonder no more. Do you fear the coming robopocalypse? This noisy wall-climbing robot will put those fears to rest. We’ll take a look at an undersea lab worthy of the Cousteau name, and finally we’ll look inside a digital pregnancy test and wonder at its unusual power switch.

Hackaday Podcast 083: Soooo Many Custom Peripherals, Leaving Bluetooth Footprints, And A Twirlybird On Mars

September 4, 2020 by 3 Comments

Hackaday editors Mike Szczys and Elliot Williams ogle the greatest hacks from the past 168 hours. Did you know that Mars Rover didn’t get launched into space all alone? Nestled in it’s underbelly is a two-prop helicopter that’s a fascinating study in engineering for a different world. Fingerprinting audio files isn’t a special trick reserved for Shazam, you can do it just as easily with an ESP32. A flaw in the way Bluetooth COVID tracing frameworks chirp out their anonymized hashes means they’re not as perfectly anonymized as planned. And you’re going to love these cool ways to misuse items from those massive parts catalogs.
