Hackaday Podcast

Hackaday editors Mike Szczys and Elliot Williams have found a critical mass of projects this week that wouldn't be possible without 3D printers. There's an absolutely astounding model roller coaster that is true to the mechanisms and physics of the original (and beholden to hours of sanding and painting). Adding sheet material to the printing process is a novel way to build durable hinges and foldable mechanisms. Elliot picks out not one, but two quadruped robot projects that leverage 3D-printed parts in interesting ways. And for the electronics geeks there's a server rack stuffed with Raspberry Pi, and analog electronic wizardry to improve the resolution of the WS2811 LED controller. We wrap it all up with discussions of flying boats, and adding Bluetooth audio to old car head units. You know you want to read the show notes!

Hackaday editors Elliot Williams and Mike Szczys bubble sort the best hardware hacks so you don't miss 'em. This week we're smitten by the perfection of a telephone tape loop message announcer. We enjoyed seeing Blender's ray tracing to design mirrors, and a webcam and computer monitor to stand in for triple-projector-based fractal fun. There's a bit of injection molding, some Nintendo Switch disassembling, and the Internet on a calculator. We close the show with a pair of Space stories, including the happy news this week that Wally Funk finally made it there! You know you want to read the show notes!

Hackaday editors Mike Szczys and Elliot Williams help you get caught up on a week of wonder hacks. We don't remember seeing a floppy drive headline the demoscene, but sure enough, there's a C64 demo that performs after the computer is disconnected. What causes bench tools to have unreliable measurements? Sometimes a poor crystal choice lets AC ruin the party. We dive into the ongoing saga of the Audacity open source project's change of ownership, and talk about generator exciter circuits -- specifically their role in starting grid-scale generators from shutdown. You know you want to read the show notes!

Hackaday editors Elliot Williams and Mike Szczys dive into a week of exceptional hacks. Tip-top of the list has to be the precision measuring instrument that uses a cable spooling mechanism. There's news that the Starlink base station firmware has been dumped and includes interesting things like geofencing for the developer modes. We saw a garage robot that will plug in your electric vehicle if you're the forgetful sort. And we close up by talking about heavier-than-air helium airships and China's Mars rover.

Hackaday editors Mike Szczys and Elliot Williams look through the most interesting hacks of the week. We spent ample time in adulation of the automatons built by François Junod; wizard-level watchmaking wrapped in endless levels of artistic detail. A couple projects stuffed into old cellphones turned Elliot's head. We got to see what happens if you spin a gear's teeth on two axes to make a universal spherical gear. And we conclude the episode with a look at how Windows 11 may send a lot of good hardware to recycle center, and at how toothpaste tubes sometimes miss the recycling center completely. Dig the show notes, you hep cats.

Hackaday editors Elliot Williams and Mike Szczys marvel at the dangerous projects on display this week, including glass etching with hydrofluoric acid and pumping 200,000 A into a 5,000 A fuse. A new board that turns the Raspberry Pi into an SDR shows off the power of the secondary memory interface (SMI) present in those Broadcom chips. We also discuss the potential for graphene in hard drives, and finish up with a teardown of a very early electronic metronome. You know you want to read the show notes!

Hackaday Editor in Chief Mike Szczys is taking a bit of vacation this week, so Managing Editor Elliot Williams is joined by Staff Writer Dan Maloney to talk about all the cool hacks and great articles that turned up this week. Things were busy, so there was plenty to choose from, but how would we not pick one that centers around strapping a jet engine to your back to rollerskate without all that pesky exercise? And what about a light bulb that plays Doom - with a little help, of course. We'll check out decals you can make yourself and why the custom keyboard crowd might want to learn that skill, learn about the other "first computer", and learn how a little radiation might be just what it takes to save an endangered species. You know you want to read the show notes!

Hackaday editors Elliot Williams and Mike Szczys marvel at the awesome hacks from the past week. We had way too much fun debated whether a wind-powered car can travel faster than the wind, and whether or not you can call that sailing. Low-temperature desoldering was demystified (it's the bismuth!) while a camera gimbal solves the problem of hand tremor during soldering. Ford just wants to become your PowerWall. And the results are in from NASA's mission to spin mice up in a centrifuge on the ISS. You know you want to read the show notes!

Hackaday editors Mike Szczys and Elliot Williams discuss a great week of hardware hacks. Two delightful mechanical hacks focus on bicycles: one that puts a differential on the front fork, and the other a flywheel between the knees. Elliot was finally impressed by something involving AI -- a machine-learning guitar pedal. You've heard of a delta bot? The tripteron is similar but with a single rail for the three arms. After a look at flip dots, tiny robots, and solar air planes we close the show geeking out about racing electric vehicles up a hill and stories of the hardware that has made closed captions possible. You know you want to read the show notes!

Hackaday editors Elliot Williams and Mike Szczys recount a week of awesome hacks. One you might have missed involves a Roku-based smart TV that was rooted and all secrets laid bare for the sole purpose of making an Ambilight setup work with it. We take a look at a creative blade-tracking system for a scrollsaw CNC project, and a robot arm that brings non-flat layers to 3D printing and envisions composite material printing. There's a great template for video glitching using inexpensive VGA to CGA converter boards, cleanly squeezed into a nice enclosure. We are a bit giddy for the omniwheel robot designs [James Bruton] has been showing off. And we finish out the show with a great conversation happening this week on Hackaday: people from throughout the community share how the chip shortage is affecting their projects. You know you want to read the show notes!

Hackaday editors Mike Szczys and Elliot Williams pick up on the neatest hacks you may have missed. We start off with another "What's that Sound?" so put your geeky-ears to the test and win a Hackaday Podcast T-shirt. Here are a couple of classic hacks to bring you joy: music based on Markov chains, and a squiggly take on the classic Nokia game of snake. For the more hardcore science geeks we dive into the B Meson news coming out of CERN's physics experiments. And after taking a detour in bristle-bot-based pen plotting, we unpack the hidden system of pipes that carry oil, gas, diesel, and more from the refinery to your region. Sidle on up to the show notes.

Hackaday editors Elliot Williams and Mike Szczys gather to ooh and aah over a week of interesting hacks. This week we're delighted to welcome special guest Kristina Panos to talk about the Inputs of Interest series she has been working on over the last couple of years. In the news is the effort to pwn the new Apple AirTags, with much success over the past week. We look at turning a screenless Wacom tablet into something more using a donor iPad, stare right into the heart of a dozen 555 die shots, and watch what happens when you only 3D print the infill and leave the perimeters out. Don't miss the show notes!

Hackaday editors Mike Szczys and Elliot Williams discuss the latest hacks from around the Internet. 3D-Printed linear rails don't sound like a recipe for a functional CNC machine but there was one this week that really surprised us. We were delighted by the procedurally generated music from a $0.03 microcontroller inside of an RCA plug (the clever flexible PCB may be the coolest part of that one). There's an interesting trick to reverse engineering Bluetooth comms of Android apps by running in a VM and echoing to WireShark. And we look at what the buzz is all about with genetically engineered mosquito experiments taking place down in the Florida Keys. New this week is a game of "What's that sound?". Use the form link on the show notes below to send in your answer, one winner will receive a podcast T-shirt. Check out the show notes!

Hackaday editors Elliot Williams and Mike Szczys select our favorite hardware hacks of the past week. This episode is packed with DIY lab instruments, including a laser microscope, a Raspberry Pi spectrometer, and a stepper motor tester that can tell you what's going on all the way down to the microsteps. We wax poetic about what modular hardware really means, fall in love with a couple of stock-ticker robots, and chat with special guest Tom Nardi about his experience at the VCF Swap Meet. Check out the show notes!

Hackaday editors Mike Szczys and Elliot Williams pull back the curtain on a week of excellent hacks. We saw an awesome use of RGB LEDs as a data channel on a drone, and the secrets of an IP camera's OS laid bare with some neat reverse engineering tools. There's an AI project for the Linux terminal that guesses at the commands you actually want to run. And after considering how far autopilot has come in the aerospace industry, we jump into a look at the gotchas you'll find when working with models of 3D scanned objects.

Hackaday editors Elliot Williams and Mike Szczys marvel at the hacks that surfaced over the past week. An eye-popping webcam hack comes in the form of an animatronic that gives that camera above your screen an eyeball to look around, an eyelid to blink with, and the skin, eyelashes, and eyebrow to complete the illusion (and make us shudder at the same time). Dan did a deep dive on Zinc Flu -- something to avoid when welding parts that contain zinc, like galvanized metals. A robot arm was given a chainsaw, leading to many hijinks; among them the headache of path planning such a machine. And we got to hear a really awesome story about resurrecting a computer game lost to obscurity, by using one of the main tools of the copyright office. For links and more, go read the show notes!

Hackaday editors Mike Szczys and Elliot Williams recap a week of great hacks. You won't want to miss the dynamometer Leo Fernekes built to measure the power output of his sterling motor (also DIY). In this age of lithium-powered multirotors, it's nice to step back and appreciate a hand-built rubberband-powered ornithopter. We have a surprising amount to say about Python's addition of the match statement (not be be confused with switch statements). And when it comes to electromechanical synth gear, it's hard to beat a spinning tape-head sequencer. Check out the show notes for links and more!

Hackaday editors Elliot Williams and Mike Szczys celebrate the cleverest projects from the week that was. We tried to catch a few fools on Thursday with our Lightmode™ and NFT articles -- make sure you go back and read those for a good chuckle if you haven't already. While those fall under not a hack, many other features this week are world-class hacks, such as the 555 timer built from 1.5-dozen vacuum tubes, and the mechanical word-clock that's 64 magnetic actuators built around PCB coils by Hackaday's own [Mortiz v. Sivers]. A treat for the ears, [Linus Akesson] aka [lft] shows off a Commodore64 that seriously sounds a good as a cathedral organ. And a masterpiece of OpenCV and Blender, you can't miss the project by [Matthew Earl] that overlays video of the Mars landing on still satellite photos... perfection! Check out the show notes!

Hackaday editors Mike Szczys and Elliot Williams curate a week of great hacks. Physical displays created in 3D space are a holy grail, and you can make one with 200 ultrasonic transducers, four FPGAs, and a lot math. Smart speakers have one heck of a microphone array in them, it's yours for the hacking if you just roll your own firmware. Hobby servos can be awful, but this week we saw they can be made really great by cracking open the DC motor to add a simple DIY position sensor. And lasers are making their way into car headlights; we illuminate the situation in this episode. Check out the show notes!

Hackaday editors Elliot Williams and Mike Szczys cover a great week of hardware hacking. We saw a fault-injection attack that used an electric flyswatter and hand-wound coil to twiddle bits inside of an AVR micro. Focus-stacking is what you want when using a microscope to image circuit boards and there's a hack for the Eakins cameras that makes it automatic. In our "can't miss articles" we riff on how to cool off cities in a warming climate, and then gaze with quiet admiration at what the Unicode standard has accomplished. But when it comes to head-spinning hacks, you can't beat the reverse-engineering efforts being shown off with the rack-mount box that made the Weather Channel awesome back in the 80's and 90's.

Hackaday editors Mike Szczys and Elliot Williams riff on the week's most interesting hacks. It's hard to imagine a more perfect piece of art than an original Pong circuit board mounted in a shadow box and playable along with some tasty FPGA tricks to capture the original look of the screen. You could make a synth with a 555 timer, but what about using 20 of them for perfect polyphony? We ogle an old video showing off a clever toothed-disc CNC machine for cutting pastry with a water jet. And the episode wouldn't be complete without looking at the strange tech that goes into making a fan car.

Hackaday editors Elliot Williams and Mike Szczys travel through the greatest hacks the week had on offer. Charge up your ice skates (literally) by adding spiked electric motors to push you across the frozen pond. If that's too cold for early March, snuggle up with a good book under the warm light of a clever lamp made from a rotary-dial telephone. We discuss CAD and CAM in your browser, and a software tool to merge images with PCB gerber files. The episode wraps up with a discussion the balance of quality versus speed when prototyping, and digesting the environmental impact of the Bitcoin network.

Hackaday editors Mike Szczys and Elliot Williams gab about all of the geeky things. We had a delightful time watching NASA bring Perseverance down to the Red planet. In Kristina's words, we pour one out for Fry's Electronics. And then we jump into a parade of excellent hacks with a magnetic bearing for crooked ball screws, a science-based poop-burning experiment, and the music hack only microcontroller enthusiasts could love as an FTDI cable is plugged directly into a speaker. Smart circuit design is used to hack a dimmer into non-dimmable LED fixtures, and an octet of living clams are the early warning sensors for water pollution.

Hackaday editors Elliot Williams and Mike Szczys recount the coolest hacks from the past week. Most clocks keep time with a quartz crystal, but we discuss one that uses a tuning fork... like the kind you use to tune a piano. Ghidra is a powerful reverse engineering tool developed by the NSA that was recently put to good use changing an embedded thermometer display from Celsius to Fahrenheit. We talk turkey on the Texas power grid problems and Tesla's eMMC failures. And of course there's some room for nostalgia as we walk down memory lane with the BASIC programming language.

Hackaday editors Mike Szczys and Elliot Williams unpack great hacks of the past week. We loves seeing the TIL311 -- a retro display in a DIP package -- exquisitely recreated with SMD electronics and resin casting. You might never need to continuously measure the diameter of your 3D printer filament, but just in case there's a clever hall-effect sensor mechanism for that. Both of us admire the work being done in the FPGA realm and this week we saw a RISC-V core plumbed into quite the FPGA stack to run a version of Doom originally played on 486 computers. And we're getting excited for the three ring circus of engineering acrobatics that will land NASA's Perseverance rover on the surface of Mars next week.

Hackaday editors Elliot Williams and Mike Szczys spin the wheel of hardware hacking brilliance. We're enamored with the quest for a root shell on a Nissan Xterra infotainment system, and smitten with a scanning microscope that uses a laser beam and precision positioning from DVD drives. We speculate on the future of artificial intelligence in the culinary arts. And this week turned up a clever way to monitor utility usage while only changing the battery on your sensor once per year.

Hackaday editors Mike Szczys and Elliot Williams discuss the greatest hacks of the week that was. Antennas aren't rocket science, so this week we really enjoyed a video that demystifies antenna designs and a project that tunes up the antennas on cheap wireless modules in the simplest of ways. Google's in the news this week with the end to project Loon, and a dust-up with the volunteer package maintainers who have spent years making sure Chromium browser is in the Linux repos. Elliot is gaga for magic eye tubes and crazy musical instruments, while Mike is over the moon for a chain-based clock display. We close up the episode talking about the Concorde, and the math behind cable mechanisms.

Hackaday editors Elliot Williams and Mike Szczys sift through a week of excellent hacks. Big news is of course the Raspberry Pi microcontroller which Elliot had a few weeks to play around with on the bench before the announcement -- it has some fascinating programmable modules (PIO) built in! Philips designed an LED light bulb that under-drives the LEDs for efficiency and long life. And Amazon added a nice little hardware disable circuit for the microphone in the Echo Flex -- a rather extreme teardown shows how they did it. Plus we talk about an open source long-range RC protocol, wall-sized pen plotter art, and a 3D printer that angles the nozzle to avoid needing support.

Hackaday editors Mike Szczys and Elliot Williams discuss our favorite hacks of the past week. We accidentally chose a theme, as most of the projects use lasers and are about machining work. We lead off with a really powerful laser that can directly etch circuit boards, only to be later outdone by an even more powerful laser using a chemistry trick to etch glass. We look at how to mix up your own rocket motors, bootstrap your own laser tag, and go down the rabbit hole of building tools for embedded development. The episode wraps up as we discuss what exactly NVMe is and where hardware hacking might take it.

Hackaday editors Elliot Williams and Mike Szczys kick off the first episode of the new year with the best hacks the internet has to offer. There's a deep dive into water-level sensing using a Christmas tree as an excuse. We ooh and ah over turning a CD-ROM drive into a CD player (miraculous tech of the previous century?). Do you have any use cases for ATtiny oscillator calibration registers? We look in on a hack that makes it dead simple to measure and set their values. The episode finishes up with a discussion of the constantly moving goal posts of virtual reality.

Hackaday editors Mike Szczys and Elliot Williams celebrate the 100th episode! It's been a pleasure to marvel each week at the achievements of awesome people and this is no different. This week there's a spinning POV display that solves pixel density and clock speed in very interesting ways. A macro keyboard made of OLED screens gives us a "do want" moment. And you can run a Raspberry Pi photo frame by sipping power from ambient light if you use the right power-tending setup. We wrap up the last episode of 2020 with a dive into ballpoint pens and solar racers. Check the show notes!

Hackaday editors Elliot Williams and Tom Nardi contemplate a few of the most interesting stories that made their way through the tubes this week. We'll learn how old VHS tapes can be turned into a unique filament for your 3D printer, and realize that the best way to learn about a 2,000 year old computer is to break out the hand drill and make one yourself. Hobby grade RC gear and a some foam board stand in for SpaceX's next-generation Mars spacecraft, and a manufacturer of cheap 3D printers attempts to undercut a popular open source project with hilarious results. Finally, we'll take a close look at some hidden aluminum boogers and discuss how China's history making trek to the Moon might be a prelude to the country making a giant leap of their own. Read the show notes!

Hackaday editors Mike Szczys and Elliot Williams round up the latest hardware hacks. This week we check out the latest dead-simple automation -- a wire cutting stripping robot that uses standard bypass strippers. Put on your rocket scientist hat and watch what happens in a 3D-printed rocket combustion chamber. Really small robots are so easy to love, this micromouse is the size of a coin. And whatever happened to those drone sightings at airports? We talk about all that, and round up the episode with Hyperloop, and Xiaomi thermometers. Read the show notes!

Hackaday editors Elliot Williams and Mike Szczys discuss the latest and greatest in geeky goodness. This week we saw a Soviet time capsule come to light with the discovery of a computer lab from a building abandoned in the 1990's. A two-cycle compressed air engine shatters our expectations of what is involved in RC aircraft design. There's a new toolkit for wireless hacking on the scene in the form of a revitalized HackRF PortaPack firmware fork. And what goes into dishwasher design? Find out in this exciting episode. Read the show notes!

In this short Thanksgiving episode, Hackaday editors Mike Szczys and Elliot Williams are talking turkey about the world of hardware hacking. We've still got news updates about the Nintendo Game and Watch hacking progress, the sad farewell to Areceibo, the new chip from Espressif, and the awesome circuit sculptures from our recent contest. We wrap up the show with a lightning round of quick hacks.

Hackaday editors Elliot Williams and Mike Szczys traverse the hackerscape looking for the best the internet had to offer last week. Nintendo has released the new Game & Watch handheld and it's already been hacked to run custom code. Heading into the darkness of winter, this artificial sun build is one not to miss... and a great way to reuse a junk satellite dish. We've found a pair of smartglasses that are just our level of dumb. And Tom Nardi cracks open some consumer electronics to find a familiar single-board computer doing "network security". https://hackaday.com/2020/11/20/hackaday-podcast…ers-cant-do-that/

Hackaday editors Mike Szczys and Elliot Williams wrangle the epic hacks that crossed our screens this week. Elliot ran deep on overclocking all three flavors of the Raspberry Pi 4 this week and discovered that heat sinks rule the day. Mike exposes his deep love of candy-coated chocolates while drooling over a machine that can detect when the legume is missing from a peanut M&M. Core memory is so much more fun when LEDs come to play, one tiny wheel is the power-saving secret for a very strange multirotor drone, and there's more value in audio cassette data transfer than you might think -- let this FPGA show you how it's done.

Hackaday editors Elliot Williams and Mike Szczys catch the best hacks you may have missed. This week we look at the new Raspberry Pi 400, use computer vision to get ready for geeky Christmas, and decypher a negative-space calendar. We get an answer to the question of what happens if you scale up a styrofoam airplane to human-size. Facebook is locking down VR headset, will hackers break them free? And take an excellent stroll down memory lane to find out what it was like to be a space-obsessed ham at the dawn of personal computers. https://hackaday.com/2020/11/06/hackaday-podcast…-shades-of-e-ink/

Hackaday editors Mike Szczys and Elliot Williams dig through the greatest hacks that ought not be missed this week. There's a wild one that flexes engineering skills instead of muscles to beat the homerun distance record with an explosively charged bat. A more elegant use of those engineering chops is shown in a CNC software tool that produces intricate wood joinery without needing an overly fancy machine to fabricate it. If your flesh and blood pets aren't keeping up with your interests, there's a new robot dog on the scene that far outperforms its constituent parts which are 3D-printed and of the Pi and Arduino varieties. And just when you thought you'd seen all the craziest retrocomputers, here's an electromechanical relay based machine that took six years to build (although there's so much going on here that it should have taken sixteen). Show notes: https://hackaday.com/?p=444464

Hackaday editors Elliot Williams and Mike Szczys chat about our favorite hacks from the past week. We start off with a bit of news of the Bennu asteroid and the new Raspberry Pi Compute Module. We drive ourselves crazy trying to understand how bobbin holders on sewing machines work, all while drooling over the mechanical brilliance of a bobbin-winding build. SCARA is the belt and pully champion of robot arms and this week's example cleverly uses redundant bearings for better precision. And we wrap up the show looking in on longform articles about the peppering of microcontrollers found on the Bluepill and wondering what breakthroughs are left to be found for internal combustion. Show notes: https://hackaday.com/?p=443437

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 transer 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. Show notes: https://hackaday.com/?p=442391

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. Show notes: https://hackaday.com/?p=435715

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. Turns out 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. Show notes: https://hackaday.com/?p=434942

Hackaday editors Elliot Williams take 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. Show notes: https://hackaday.com/?p=433621

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 the controller for it is fittingly 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. Show notes: https://hackaday.com/?p=432406

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. Show notes: https://hackaday.com/?p=431146

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. Show notes: https://hackaday.com/?p=430419

Hackaday editors Elliot Williams and Mike Szczys check in on the best hacks from the past week. All the buzz is the algorithm that can reverse engineer your house keys from the way they sound going into the lock. Cardboard construction goes extreme with an RC car build that's beyond wizard-level. Speaking of junk builds, there's a CNC mill tipped on its side grinding out results worlds better than you expect from salvaged CD-ROM drives. And a starburst character display is a clever combination of laser cutting and alternative using UV-cured resin as a diffuser. Show notes: https://hackaday.com/?p=429459

Hackaday editors Mike Szczys and Tom Nardi chew the beef tallow as they take a tour through some of the best and most interesting articles from the past week, from kicking off another round of the popular Circuit Sculpture contest to building artisan coffee makers. We'll look at the engineering behind the post-apocalyptic face mask launcher of our nightmares, and stand in awe at the intersection of orbiting spacecraft and lawn emojis. Several tiny remote controlled vehicles will be discussed, and we'll take an unexpected look at how extruding plastic and aluminum might not be so different after all. Make sure to stick around until the end to learn why a little-known locomotive technology of the 1840s really sucked. Show notes: https://hackaday.com/?p=428104

Hackaday editors Elliot Williams and Mike Szczys flip through the index of great hacks. This week we learn of a co-existence attack on WiFi and Bluetooth radios called Spectra. The craftsmanship in a pneumatic drone is so awesome we don't care that it doesn't fly. Building a powerful TEA laser is partly a lesson in capacitor design. And join us in geeking out at the prospect of big rigs getting their juice from miles of overhead wires. Show notes: https://hackaday.com/?p=426831
