Ep 117: Chiptunes in an RCA Plug, an Arduino Floppy Drive, $50 CNC, and Wireless Switches
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?".

Ep116: Three DIY Lab Instruments, Two Tickers, and a MicroCar
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.

Ep115: AI is Bad at Linux Terminal, Puppeting Pico in Python, 3D Scanning Comes Up Short
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.

Ep114: Eye is Watching You, Alien Art, CNC Chainsaw, and the Galvie Flu
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!

Ep113: Python Switching to Match, a Magnetic Dyno, a Flying Dino, and a Spinning Sequencer
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!

Ep 112: We Have an NFT, Racing a Mobius Strip, and Syncing Video with OpenCV and Blender
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!

Ep111: 3D Graphics are Ultrasonic, Lobotomizing Alexa, 3D-Printing Leaky Rockets, and Gaming the Font System
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!

Ep110: One Unicode to Rule Them, Hacking Focus Stacking, Virtual Typing, and Zombie Weather Channel
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.

Ep109: Cars that Suck, a Synth Packed with 555s, X-ray Letter Reading, and Pecking at a PS/2 Keyboard
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.

Ep108: Eulogizing Daft Punk Helmets, Bitcoin Feeling the Heat, Squeezing Soft Robots, and Motorizing Ice Skates
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.

Ep107: FTDI Plays Music, LED Dimming Ain't Easy, Measuring Poop Calories, and Sketchy Laser Cutters
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.

Ep106: Connector Kerfuffle, Tuning Fork Time, Spinach Contact Prints, and Tesla's Permanent Memory
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.

Ep 105: 486 Doom on FPGA, How Thick is Your Filament, Raspberry Pi Speaks Android Auto, and We're Headed to Mars
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.

Ep104: Delicous AI, DVD Scanning Microscope, and Battery-Friendly Microcontroller Designs
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.

Ep 103: Antennas for Everyone, a Clock Made of Chains, Magic Eye Tubes, and a Little Google Bashing
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.

Ep102: Raspberry Pi Microcontroller, Microphone Killswitch, and a 45-Degree 3D-Printer
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.

Ep101: Lasering and Milling Absolutely Everything
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.

Ep100: Arduino Plays CDs, Virtual Reality in the 60s, and Magical Linear Actuators
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.

Ep099: Our Hundredth Episode! Denture Synth, OLED Keycaps, and SNES Raytracing
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!

Ep098: China's Moon Rocks, Antikythera Revelations, Creality vs Octoprint, and RC Starship
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.
