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

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

Ep030: 7 Years of RTL-SDR, 3D Prints Optimized for the Eye, Sega Audiophile, Swimming in Brighteners
Hackaday Editors Mike Szczys and Elliot Williams curate the awesome hacks from the past week. On this episode, we marvel about the legacy RTL-SDR has had on the software-defined radio scene, turn a critical ear to 16-bit console audio hardware, watch generative algorithms make 3D prints beautiful, and discover why printer paper is so very, very bright white.

Ep029: Your Face in Silver Sand, Tires of the Future, ESP32 all the CNC Things, and Sub in a Jug
Hackaday Editors Elliot Williams and Mike Szczys geek out over the latest hacks. This week we saw a couple of clever CNC builds that leverage a great ESP32 port of GRBL. The lemonade-pitcher-based submarine project is everything you thought couldn't work in an underwater ROV. Amazon's newest Dot has its warranty voided to show off what 22 pounds gets you these days. And there's a great tutorial on debugging circuits that grew out of a Fail of the Week. Plus, we get the wind knocked out of us with an ambitious launch schedule for airless automotive tires, and commiserate over the confusing world of USB-C. Show Notes: https://hackaday.com/?p=370038

Ep028: Brain Skepticism Turned Up to 11, Web Browsing in '69, Verilog For 7400 Logic
Hackaday Editors Mike Szczys and Elliot Williams cover the most interesting hacks over the past week. So much talk of putting computers in touch with our brains has us skeptical on both tech and timeline. We celebrated the 40th Anniversary of the Walkman, but the headphones are the real star. Plus, Verilog isn't just for FPGAs, you can synthesize 7400 circuits too! Elliot is enamored by a subtractive printing process that uses particle board, and we discuss a couple of takes on hybrid-powered drones. Show Notes: https://hackaday.com/?p=368984

Ep027: Confusingly USB-C, Glowey Displays, Logically VGA, Hackers that Changed Gaming
Hackaday Editors Elliot Williams and Mike Szczys dive into the most interesting hacks of the week. Confused by USB-C? So are we, and so is the Raspberry Pi 4. Learning VGA is a lot easier when abstract concepts are unpacked onto a huge breadboard using logic chips and an EEPROM. Adding vision to a prosthetic hand makes a lot of sense when you start to dig into possibilities of this Hackaday Prize entry. And Elliot gets nostalgic about Counter-Strike, the game that is a hack of Half-Life, grew to eclipse a lot of other shooters, and is now 20 years old. Show Notes: https://hackaday.com/?p=366837
