Supercon Talk: Mike Szczys Runs Down The State Of The Hackaday 2019

2019 was a great year for Hackaday. It marked the fifteenth year of the hacker community’s hive-brain, which is essentially forever in Internet Years, and we’re still laser-focused on bringing you the hacks that inspire you to create the hacks that inspire someone else to create the hacks of tomorrow. We’re immensely proud that Hackaday remains a must-read in the worldwide community of folks doing creative things with technology.

At the Superconference, our editor-in-chief Mike Szczys covered the best new developments here at Hackaday HQ in 2019: new weekly columns, mobile-friendly formats for both Hackaday’s front page and the mobile app for Hackaday.io, our podcast, some great new contests, and a ton of great in-depth original articles from our crew of writers. And that’s just what was new last year.

The part of Mike’s talk that I enjoyed the most, though, was his look back fifteen years ago to when Hackaday was just born. In the intervening 5,545 days, we’ve written more than 34,718 articles. (So much for “hack-a-day”, he says, doing the math.) We’re nearing our millionth comment. That’s a lot of Hackaday. So it’s fun to ask what has changed over this time, and track it through the memory of a hardware hacker.

Dig the old image styling! Groovy.

Back in 2008, Hackaday was a spry four-year-old, and we were featuring robot hacks where the brains and Internet connectivity were provided by WRT-54G routers, SMS connectivity was provided by hacking into a Nokia 3100, and the battery weighed more than the motors yet only lasted fifteen minutes. Today’s hacks toss in an ESP32, any old cheap SMS module, and an off-the-shelf Li-Ion battery pack and will run for days. Don’t even get me started on 3D printers. Or the ease of writing software for any of these machines. We’ve never lived in better times!

But that doesn’t mean that every project has to be a superconducting supercollider either; it’s equally important to showcase our simpler projects too, to give new people a foothold into the hacking scene. And it’s similarly crucial to show people how you failed, tried, and tried again before declaring victory. If all of our finished projects look like they were conjured out of thin air, it hides all of the learning that went into them, and that’s where a lot of the real gold is buried.

While we add features, media come and go, and the cutting edge becomes less and less distinguishable from magic, one thing remains constant: showing each other what we’re up to, sharing our best tips and tricks, and pushing forward the hacker state of the art. Long live Hackaday!

Phantom Express: The Spaceplane That Never Was

Even for those of us who follow space news closely, there’s a lot to keep track of these days. Private companies are competing to develop new human-rated spacecraft and assembling satellite mega-constellations, while NASA is working towards a return the Moon and the first flight of the SLS. Between new announcements, updates to existing missions, and literal rocket launches, things are happening on a nearly daily basis. It’s fair to say we haven’t seen this level of activity since the Space Race of the 1960s.

With so much going on, it’s no surprise that not many people have heard of the XS-1 Phantom Express. A project by the United States Defense Advanced Research Projects Agency (DARPA), the XS-1 was designed to be a reusable launch system that could put small payloads into orbit on short notice. Once its mission was complete, the vehicle was to return to the launch site and be ready for re-flight in as a little as 24 hours.

Alternately referred to as the “DARPA Experimental Spaceplane”, the vehicle was envisioned as being roughly the size of a business jet and capable of carrying a payload of up to 2,300 kilograms (5,000 pounds). It would take off vertically under rocket power and then glide back to Earth at the end of the mission to make a conventional runway landing. At $5 million per flight, its operating costs would be comparable with even the most aggressively priced commercial launch providers; but with the added bonus of not having to involve a third party in military and reconnaissance missions which would almost certainly be classified in nature.

Or at least, that was the idea. Flight tests were originally scheduled to begin this year, but earlier this year prime contractor Boeing abruptly dropped out of the program. Despite six years in development and over $140 million in funding awarded by DARPA, it’s now all but certain that the XS-1 Phantom Express will never get off the ground. Which is a shame, as even in a market full of innovative launch vehicles, this unique spacecraft offered some compelling advantages.

Hackaday Podcast 060: Counting Bees, DogBox Transmissions, And The Lowdown On Vents, BiPAP, And PCR

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.

Self-Playing Whistle While You Work From Home

In ridiculous times, it can help to play ridiculous instruments such as the slide whistle to keep your bristles in check. But since spittle is more than a little bit dangerous these days, it pays to come up with alternative ways to play away the days during lockdown life.

Thanks to some clever Arduino-driven automation, [Gurpreet] can maintain a safe distance from his slide whistle while interacting with it. Slide whistles need two things — air coming in from the top, and actuation at the business end. The blowing force now comes from a focused fan like the ones that cool your printed plastic as soon as the hot end extrudes it. A stepper motor moves the slide up and down using a printed rack and pinion.

Here’s a smooth touch — [Gurpreet] added a micro servo to block and unblock the sound hole with a cardboard flap to make the notes more distinct. Check out the build video after the break, which includes a music video for “My Heart Will Go On”, aka the theme from Titanic. It’s almost like the ship herself is playing it on the steam whistles from the great beyond.

Speaking of, did you hear about the effort to raise and restore the remains of her radio room?

This Week In Security: 0-Days, Pwn2Own, IOS And Tesla

LILIN DVRs and cameras are being actively exploited by a surprisingly sophisticated botnet campaign. There are three separate 0-day vulnerabilities being exploited in an ongoing campaigns. If you have a device built by LILIN, go check for firmware updates, and if your device is exposed to the internet, entertain the possibility that it was compromised.

The vulnerabilities include a hardcoded username/password, command injection in the FTP and NTP server fields, and an arbitrary file read vulnerability. Just the first vulnerability is enough to convince me to avoid black-box DVRs, and keep my IP cameras segregated from the wider internet.

Faking Your Way To USB-C Support On Laptops Without It

Is there no end to the dongle problem? We thought the issue was with all of those non-USB-C devices that want to play nicely with the new Macbooks that only have USB-C ports. But what about all those USB-C devices that want to work with legacy equipment?

Now some would say just grab yourself a USB-C to USB-A cable and be done with it. But that defeats the purpose of USB-C which is One-Cable-To-Rule-Them-All[1]. [Marcel Varallo] decided to keep his 2011 Macbook free of dongles and adapter cables by soldering a USB-C port onto a USB 2.0 footprint on the motherboard.

How is that even possible? The trick is to start with a USB-C to USB 3 adapter. This vintage of Macbook doesn’t have USB 3, but the spec for that protocol maintains backwards compatibility with USB 2. [Marcel] walks through the process of freeing the adapter from its case, slicing off the all-important C portion of it, and locating the proper signals to route to the existing USB port on his motherboard.

[1] Oh my what a statement! As we’ve seen with the Raspberry Pi USB-C debacle, there are actually several different types of USB-C cables which all look pretty much the same on the outside, apart from the cryptic icons molded into the cases of the connectors. But on the bright side, you can plug either end in either orientation so it has that going for it.

Measuring UV-C For About $5

Looking to sterilize something? Give it a good blast of the old UV-C. Ultraviolet radiation in the shortest wavelength band breaks down DNA and RNA, so it’s a great way to kill off any nasties that are lurking. But how much UV-C are you using? [Akiba] at Hackerfarm has come up with the NukeMeter, a meter that measures the output of their UV-C sterilizer the NukeBox. It is built around a $2.50 sensor and a $3 Arduino.
