Hackaday Podcast

Hackaday editors Mike Szczys and Elliot Williams sort through all of the hacks to find the most interesting hardware projects you may have missed this week. Did you know you can use machine learning without a neural network? Here's a project that does that on an ATtiny85. We also wrap our minds around a 3D-printed press brake, look at power-saving features of the ESP32 that make it better on a battery, and discuss the IoT coffee maker hack that's so good it could be a stock feature. Plus we dive into naturally occurring nuclear reactors and admire the common, yet marvelous, bar code. Show Notes: https://hackaday.com/?p=393832

Hackaday editors Elliot WIlliams and Mike Szczys kick off the first podcast of the new year. Elliot just got home from Chaos Communications Congress (36c3) with a ton of great stories, and he showed off his electric cargo carrier build while he was there. We recount some of the most interesting hacks of the past few weeks, like 3D-printed molds for making your own paper-pulp objects, a rudimentary digital camera sensor built by hand, a tattoo-removal laser turned welder, and desktop-artillery that's delivered in greeting-card format.

Hackaday editors Mike Szczys and Elliot get to gether for the 47th and final Hackaday Podcast of 2019. We dive into the removable appendix on Prusa's new "Buddy" control board, get excited over the world's largest grid-backup battery, and commiserate about the folly of designing enclosures as an afterthought. There's some great research into which threaded-inserts perform best for 3D-printed parts, how LEDs everywhere should be broadcasting data, and an acoustic organ that's one-ups the traditional jug band.

Hackaday editors Elliot Williams and Mike Szczys highlight the most delightful hacks of the past week. Need a random-number showpiece for your office? Look no further than that fish tank. Maybe the showpiece you actually need is to complete your band's stage act? You want one of Tristan Shone's many industrial-chic audio controllers or maybe just a hacked turntable sitting between your guitar and amp.  Plus citizen science is alive and well in the astronomy realm, and piezo elements are just never going to charge your electric vehicle.

Hackaday Editors Mike Szczys and Elliot Williams talk over the last three weeks full of hacks. Our first "back to normal" podcast after Supercon turns out to still have a lot of Supercon references in it. We discuss Raspberry Pi 4's HDMI interfering with its WiFi, learn the differences between CoreXY/Delta/Cartesian printers, sip on Whiskey aged in an ultrasonic jewelry cleaner, and set up cloud printing that's already scheduled for the chopping block. Along the way, you'll hear hints of what happened at Supercon, from the definitive guide to designing LEDs for iron-clad performance to the projects people hauled along with them.

In this special Superconference edition of the podcast, Kerry Scharfglass and Elliot Williams pick up their microphones and try to capture the spirit of the Supercon. Read More: https://wp.me/paBn4l-1CIw

Before you even ask, it's an open source trackball and you're gonna like it. Hackaday Editors Mike Szczys and Elliot Williams get down to brass tacks on this week's hacks. From laying down fatter 3D printer extrusion and tricking your stick welder, to recursive Nintendos and cubic Castlevania, this week's episode is packed with hacks you ought not miss.

Hackaday Editors Elliot Williams and Mike Szczys talk turkey on the latest hacks. Random numbers, art, and electronic geekery combine into an entropic masterpiece. We saw Bart Dring bring new life to a cool little multi-pen plotter from the Atari age. Researchers at UCSD built a very very very slow soft robot, and a broken retrocomptuer got a good dose of the space age. A 555 is sensing earthquakes, there's an electric motor that wants to drop into any vehicle, and did you know someone used to have to read the current time into the telephone ad nauseam?

Hackaday Editors Mike Szczys and Elliot Williams shed some light on a true week of hacks. It seems like all kinds of projects are doing this the "wrong" way this week and its delightful to see what they learn along the way. Hovercrafts can work using the coanda effect which uses the blowers on the outside. You can dump your Linux logs to soldered-on eMMC memory, and chain sprockets can be cut from construction brackets. If you really want to build your own rebreather you can. All of these hacks work, and seeing how to do something differently is an inspiring tribute to the art of hardware hacking... you can learn a lot by asking yourself why these particular techniques are not the most commonly used. Plus, Mike caught up with Alessandro Ranellucci at Maker Faire Rome last weekend. In addition to being the original author of slic3r, Alessandro has been Italy's Open Source lead for the last several years. He talks about the legislation that was passed earlier this year mandating that software commissioned by the government must now be Open Source and released with an open license.

Hackaday Editors Mike Szczys and Elliot Williams opine on the coolest hacks we saw this week. This episode is heavy with 3D printing as Prusa released a new, smaller printer, printed gearboxes continue to impress us with their power and design, hoverboards are turned into tanks, and researchers suggest you pour used coffee grounds into your prints. Don't throw out those "toy" computers, they may be hiding vintage processors. And we have a pair of fantastic articles that cover the rise and fall of forest fire watchtowers, and raise the question of where all those wind turbine blades will go when we're done with them.
