Ep040: 3D Printed Everything, Strength v Toughness, Blades of Fiber, and What Can't Coffee Do? Oct 18, 2019

Show notes

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.

Ep039: Elliot <3 Lightning Detector, Ikea Dark Mode, Smartest Watch, Solar Sailing, VAWT Controversy Oct 10, 2019

Show notes

Hackaday Editors Elliot Williams and Mike Szczys recap a week full of hacks from the solar sailing RC plane that has zero power storage to geeking out about lightning detectors and hacking Ikea LED controllers to unlock real dimming to building backyard wind turbines. We look up an IoT egg tray with appreciation not for the concept but certainly for the engineering, and scratch our heads on why one-hacker-smartwatch-to-rule-them-all seems like something that should happen but so far has only been a fleeting concept.

Ep038: Cyberdecks, Resin 3D-Printing vs FDM, Silicone Injection Molding, the Pickle Fork Fiasco Oct 04, 2019

Show notes

Hackaday Editors Tom Nardi and Mike Szczys comb through their favorite hacks from the past week. We loved Donald Papp's article on considerations before making the leap from FDM 3D Printers to a resin-based process, and we solidify our thoughts on curing cement in low-gravity. Tom's working on a Cyberdeck build, and he also found an ancient episode of an earlier and much different version of the Hackaday podcast. We're impressed with a mostly 3D-printed useless machine, a thermal-insert press that's also 3D-printed, and the Raspberry-Pi based Sidekick clone that popped up this week. A DIY wire-bending robot is an incredible build, as is the gorgeous wire-routing in a mechanical keyboard, and the filigree work on this playing card press. Plus you need to spend some time getting lost in this one hydrogen-line telescope project. Show Notes: https://hackaday.com/?p=379616

Ep037: 2 Flavors of Robot Dog, Fitness Tracker Hacks, Clocks Wind Themselves, Helicopter Chainsaws Sep 27, 2019

Show notes

Hackaday Editors Mike Szczys and Elliot Williams take a look at the latest hacks from the past week. We keep seeing awesome stuff and find ourselves wanting to buy cheap welders, thermal camera sensors, and CNC parts. There was a meeting of the dog-shaped robots at ICRA and at least one of them has super-fluid movements. We dish on 3D printed meat, locking up the smartphones, asynchronous C routines, and synchronized clocks. Show Notes: https://hackaday.com/?p=378386

Ep036: Camera Rig Makes CNC Jealous, Become Your Own Time Transmitter, Pi HiFi 80s Vibe, DJ Xiaomi Sep 20, 2019

Show notes

Hackaday Editors Elliot Williams and Mike Szczys work their way through a fantastic week of hacks. From a rideable tank tread to spoofing radio time servers and from tune-playing vacuum cleaners to an epic camera motion control system, there's a lot to get caught up on. Plus, Elliot describes frequency counting while Mike's head spins, and we geek out on satellite optics, transistor-based Pong, and Jonathan Bennett's weekly security articles.

Ep035: LED Cubes Taking Over, Ada Vanquishes C Bugs, Rad Monitoring is Hot, 3D Printing Goes Full 3D Sep 12, 2019

Show notes

Hackaday Editors Mike Szczys and Elliot Williams get caught up on the most interesting hacks of the past week. On this episode we take a deep dive into radiation monitoring projects, both Geiger tube and scintillator based, as well as LED cube projects. In the 3D printing world we want non-planar printing to be the next big thing. Padauk microcontrollers are small, cheap, and do things in really interesting ways if you don't mind embracing the ecosystem. And what's the best way to read a water meter with a microcontroller?

Ep034: 15 Years of Hackaday, ESP Hacked, Hydrogen Sipping Cars, Giant Drawbot, Really Remote RC Cars Sep 06, 2019

Show notes

Elliot Williams and Mike Szczys wish Hackaday a happy fifteenth birthday! We also jump into a few vulns found (and fixed... ish) in the WiFi stack of ESP32/ESP8266 chips, try to get to the bottom of improved search for 3D printable CAD models, and drool over some really cool RC cars that add realism to head-to-head online racing. We look at the machining masterpiece that is a really huge SCARA arm drawbot, ask why Hydrogen cars haven't been seeing the kind of sunlight that fully electric vehicles do, and give a big nod of approval to a guide on building your own custom USB cables.

Ep033: Decompressing from Camp, Nuclear Stirling Engines, Carphone or Phonecar, and ArduMower Aug 30, 2019

Show notes

Hackaday Editors Mike Szczys and Elliot Williams recorded this week's podcast live from Chaos Communication Camp, discussing the most interesting hacks on offer over the past week. I novel locomotion news, there's a quadcopter built around the coanda effect and an autonomous boat built into a plastic storage bin. The radiation spikes in Russia point to a nuclear-powered ramjet but the idea is far from new. Stardust (well... space rock dust) is falling from the sky and it's surprisingly easy to collect. And 3D-printed gear boxes and hobby brushless DC motors have reached the critical threshold necessary to mangle 20/20 aluminum extrusion. Show Notes: https://hackaday.com/?p=374187

Ep032: Meteorite Snow Globes, Radioactive Ramjet Rockets, Autonomous Water Boxes, and Ball Reversers Aug 23, 2019

Show notes

Ep 031: Holonomic Drives, Badges of DEF CON, We Don't Do On-Chip Debugging, and Manufacturing Snafus Aug 16, 2019

Show notes

Mike Szczys and Kerry Scharfglass recorded this week's podcast live from DEF CON. Among the many topics of discussion, we explore some of the more interesting ways to move a robot. From BB-8 to Holonomic Drives, Kerry's hoping to have a proof of concept in time for Supercon. Are you using On-Chip Debugging with your projects? Neither are we, but maybe we should. The same goes for dynamic memory allocation; but when you have overpowered micros like the chip on the Teensy 4.0, why do you need to? We close this week's show with a few interviews with badge makers who rolled out a few hundred of their design and encountered manufacturing problems along the way. It wouldn't be engineering without problems to solve. Show Notes: https://hackaday.com/?p=372073
