Ep103: Antennas for Everyone, a Clock Made of Chains, Magic Eye Tubes, and a Little Google Bashing
29 januari 2021 · 49 min
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. Lees meer

Ep102: Raspberry Pi Microcontroller, Microphone Killswitch, and a 45-Degree 3D-Printer
22 januari 2021 · 53 min
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. Lees meer

Ep101: Lasering and Milling Absolutely Everything
15 januari 2021 · 42 min
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. Lees meer

8 januari 2021 · 59 min
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. Lees meer

Ep098: China's Moon Rocks, Antikythera Revelations, Creality vs Octoprint, and RC Starship
18 december 2020 · 58 min
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. Lees meer

13 november 2020 · 1 uur 5 min
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.

Ep091: Louisville Exploder, Generating Japanese Joinery, Relay Retrocomputer Rally, and Chop the Robopup
30 oktober 2020 · 57 min
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).

Ep089: 770 Potato Battery, Printing Resin Resist, and No-Internet Video Chat
16 oktober 2020 · 45 min
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.

Ep087: Sound-Shattering Gliders Pressing Dashcam Buttons, and Ratcheting Up Time
2 oktober 2020 · 54 min
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.

18 september 2020 · 51 min
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 Lees meer

Ep083: Soooo Many Custom Peripherals, Leaving Bluetooth Footprints, and a Twirlybird on Mars
3 september 2020 · 57 min
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 Lees meer

Ep082: DJ CNC, NFC Black Box, Sound of Keys, and Payin' for 3D Prints
28 augustus 2020 · 58 min
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 Lees meer

There was a kerfuffle about whether a ventilator data dump from Medtronics was open source or not, and cool hacks from machine-learning soldering iron controllers to 3D-printing your own solder paste stencils. A motion light teardown shows it's not being done with passive-infrared, we ask what's the deal with Tim Berners-Lee's decentralized internet, and we geek out about keyboards that aren't QWERTY.

Ep060: Counting Bees, DogBox Transmissions, and the Lowdown on Vents, BiPAP, and PCR
27 maart 2020 · 1 uur 6 min
Hackaday editors Elliot Williams and Mike Szczys recount the past week in hardware hacking. There's a new king of supercomputing and it's everyone! Have you ever tried to count bees? Precision is just a cleverly threaded bolt away. And we dig into some of the technical details of the coronavirus response with a close look at PCR testing for the virus, and why ventilators are so difficult to build.

Ep059: Hydraulic Rockets & Presses, Machine Vision Bounces & Stares, Smart Speakers Listen to You
19 maart 2020 · 1 uur 5 min
Hackaday editors Mike Szczys and Elliot Williams undertake a journey through the week of fantastic hacks. Add a new level of complexity to model rockets by launching them from a silo via pneumatic ram before the combustibles even get involved. The eyes of that sculpture are actually following you -- and with laser focus! The Game Boy is a pillar of pop culture for a reason, there's a superb talk that outlines all of the interesting choices that made the electronics so special. We round out the show with a rousing discussion of a space tow truck and a scholarly look at the sporadic wake patter of Alexa et al. Show notes: https://hackaday.com/?p=404008 Lees meer

Ep058: Motorheads, 3D Prints that Bend Metal, and Homebuilt Onewheel Death Machines
13 maart 2020 · 52 min
Hackaday editor Elliot Williams and contributor Jonathan Bennett discuss the past week of Hackaday. Freeman Dyson, who wanted to send us to space on the back of nuclear explosions, passed away. Only slightly less dangerous, we looked at self-balancing vehicles, 3D printed press brakes, and making rubies in the home lab. All the usual suspects make cameo appearances: robots, FPGAs, and open-source software. Show notes: https://hackaday.com/?p=402113 Lees meer

Ep057: Dismantled LCD Panels, Unexpected Dynamometer, a Flappy POV, and Dastardly Encryption
6 maart 2020 · 59 min
Hackaday editors Mike Szczys and Elliot Williams are onto an LCD and motors kick this week. Two different LCD screen teardowns caught our eye as one lets you stare into the void while using your iMac and the other tries to convince us to be not afraid of de-laminating the LCD stackup. On the motors front, it's all about using magnets and coils in slightly different ways; there's a bike generator that uses a planar alternator design, a dynamometer for testing motor power that itself is built from a motor, and a flex-PCB persistence of vision display that's a motor/display hybrid. We round out the episode with talk of the newly revealed espionage saga that was Crypto AG, and riveting discussion of calculators, both real and virtual.

Ep056: Cat of 9 Heads, Robot Squats, PhD in ESP32, and Did You Hear About Sonos?
28 februari 2020 · 57 min
Hackaday editors Elliot Williams and Mike Szczys gab on great hacks of the past week. Did you hear that there's a new rev of the Pi 4 out there? We just heard... but apparently it's release into the wild was months ago. Fans of the ESP8266 are going to love this tool that flashes and configures the board, especially for Sonoff devices. Bitluni's Supercon talk was published this week and it's a great roadmap of all the things you should try to do with an ESP32. Plus we take on the Sonos IoT speaker debacle and the wacky suspension system James Bruton's been building into his humanoid robot. Show notes: https://hackaday.com/?p=401004 Lees meer

Ep055: Most Cyberpunk Synthesizer, Data in Your Cells, Bubbly in Your Printer, & Dystopian Peepshow
21 februari 2020 · 50 min
Hackaday editors Mike Szczys and Elliot Williams discuss the many great hacks of the past week. Just in case you missed the fact that we're living in the cyberpunk future, you can now pop off your prosthetic hand and jack directly into a synthesizer. The robot headed for Mars has a flying drone in its belly. Now they're putting foaming agent in filament to make it light and flexible. And did you ever wonder why those pinouts were so jumbled?

Ep054: Xenomorph Cookies, 101 Uses for Hot Glue, Rolling Robots, and a Clippy Computer
14 februari 2020 · 58 min
Hackaday editors Elliot Williams and Mike Szczys reflect on great hacks of the past few days. Strain relief is something every electronics geek encounters and there's a spiffy way to make your hot-glue look like a factory connector. There's something in the air and it seems to be recreating early computers. Did you know astronauts are baking cookies they're forbidden to eat? And did you hear about the 3D printer that's being fed oil from the deep fryer? Show notes: https://hackaday.com/?p=399039 Lees meer
