Start Your Engines: The FPV Contest Begins Now!

November 22, 2022 by Elliot Williams 15 Comments

There are places that you can go in person, but for everything else, there’s FPV. Whether you’re flying race quads, diving the depths in a yellow submarine, or simply roving the surface of the land, we want to see your builds. If it’s remote controlled, and you feel like you’re in the pilot’s seat, it’s FPV.

When you say “first person view” many of you will instinctively follow up with “flight” or “drone”. But given the ease of adding a camera and remote control to almost any vehicle, there’s no reason to only fly the FPV skies. (Of course, we want to see your crazy quadcopter builds too.)

We went looking for a few less-traditional examples to whet your appetite, and we found a lot. There are super-cute FPV bots for indoors and more robust tanks for cruising around the neighborhood. In the summer, you’ll probably need an FPV lawnmower, and for the winter, naturally, an FPV snowblower or a budget-friendly FPV snow-boat. Or skip the outdoors entirely and terrorize the pool with an FPV sub.

This contest isn’t exclusively about the vehicles either. If you’re working on the tech that makes FPV possible, we want you to enter. For instance, this simple quad/drone tracker will help keep your video feed running and your mind on flying. This cockpit will make the immersion more complete. And nobody likes the jello-cam effect that excess vibration can cause, so we’d like to see camera hacks as well.

And of course, your quads. Is your FPV quad too fast, too light, or does it fly too far? Show us. The contest starts now and runs until Jan 3, 2023, and there are three $150 shopping sprees courtesy of Digi-Key on the line. Get hacking!

Hackaday Links: November 20, 2022

November 20, 2022 by Dan Maloney 16 Comments

Lots of space news this week, with the big story being that Artemis I finally blasted off for its trip to the Moon. It was a spectacular night launch, with the SLS sending the crew-rated but vacant — well, mostly vacant — Orion spacecraft on a week-ish long trip to the Moon, before spending a couple of weeks testing out a distant retrograde orbit. The mission is already returning some stunning images, and the main mission goal is to check out the Orion spacecraft and everything needed for a crewed Artemis II lunar flyby sometime in 2024. If that goes well, Artemis III will head up in 2025 with a crew of four to put the first bootprints on the Moon in over 50 years.

Of course, like the Apollo missions before it, a big part of the crewed landings of the Artemis program will likely be the collection and return of more lunar rock and soil samples. But NASA likes to hedge its bets, which is perhaps why they’ve announced an agreement to purchase lunar regolith samples from the first private company to send a lander to the Moon. The Japanese start-up behind this effort is called ispace, and they’ve been issued a license by the Japanese government to transfer samples collected by its HAKUTO-R lander to NASA. Or rather, samples collected on the lander — the contract is for NASA to take possession of whatever regolith accumulates on the HAKUTO-R’s landing pads. And it’s not like ispace is going to return the samples — the lander isn’t designed to ever leave the lunar surface. The whole thing is symbolic of the future of space commerce, which is probably why NASA is only paying $5,000 for the dirt.

Brainstorming

November 19, 2022 by Elliot Williams 5 Comments

One of the best things about hanging out with other hackers is the freewheeling brainstorming sessions that tend to occur. Case in point: I was at the Electronica trade fair and ended up hanging out with [Stephen Hawes] and [Lucian Chapar], two of the folks behind the LumenPnP open-source pick and place machine that we’ve covered a fair number of times in the past.

Among many cool features, it has a camera mounted on the parts-moving head to find the fiducial markings on the PCB. But of course, this mean a camera mounted to an almost general purpose two-axis gantry, and that sent the geeks’ minds spinning. [Stephen] was talking about how easy it would be to turn into a photo-stitching macrophotography rig, which could yield amazingly high resolution photos.

Meanwhile [Lucian] and I were thinking about how similar this gantry was to a 3D printer, and [Lucian] asked why 3D printers don’t come with cameras mounted on the hot ends. He’d even shopped this idea around at the East Coast Reprap Festival and gotten some people excited about it.

So here’s the idea: computer vision near extruder gives you real-time process control. You could use it to home the nozzle in Z. You could use it to tell when the filament has run out, or the steppers have skipped steps. If you had it really refined, you could use it to compensate other printing defects. In short, it would be a simple hardware addition that would open up a universe of computer-vision software improvements, and best of all, it’s easy enough for the home gamer to do – you’d probably only need a 3D printer.

Now I’ve shared the brainstorm with you. Hope it inspires some DIY 3DP innovation, or at least encourages you to brainstorm along below.

Hackaday Podcast 193: Found Computers, Internet Over WhatsApp, Two-Factor C64, Shifting Cars, And Self-Shooting Fighter Planes

November 18, 2022 by Dan Maloney 4 Comments

This week, Editor-in-Chief Elliot Williams and Staff Writer Dan Maloney review the literature on a hack-packed week of action. We’ll find a Linux machine inside just about anything, including curb-side TVs and surprisingly secure EV chargers. No Internet? No problem — just tunnel IP through WhatsApp! We’ll see that 3D printers can be repurposed for lab automation of the cheap, build the worst — but coolest — 2FA dongle of all time, and see how a teetering tower of cards can make your old motherboard think any ISA card is plugged into it. Worried that driving an EV is going to be a boring experience? Don’t be — maybe you’ll still get to jam through the gears. But if you do, rest assured there’ll be plenty of careful engineering done to see if it’s safe. Err, at least we hope so…

This Week In Security: Mastodon, Fake Software Company, And ShuffleCake

November 18, 2022 by Jonathan Bennett 15 Comments

Due to Twitter’s new policy of testing new features on production, the interest in Mastodon as a potential replacement has skyrocketed. And what’s not to love? You can host it yourself, it’s part of the Fediverse, and you can even run one of the experimental forks for more features. But there’s also the danger of putting a service on the internet, as [Gareth Heyes] illustrates by stealing passwords from, ironically, the infosec.exchange instance.

Will The Fax Machine Ever Stop Singing?

November 16, 2022 by Kristina Panos 43 Comments

Throughout the 80s and 90s, you couldn’t swing a stapler around any size office without hitting a fax machine. But what is it about the fax machine that makes it the subject of so much derision? Is it the beep-boops? The junk faxes? Or do they just seem horribly outdated in the world of cloud storage and thumb drives? Perhaps all of the above is true. While I may be Hackaday’s resident old school office worker et cetera, it may surprise you to learn that I don’t have a fax machine. In fact, the last time I had to fax something, I recall having to give my email address to some website in order to send a single fax for free.

Over across the pond, the UK government has decided to nix the requirement for fax services under something called the Universal Service Order (USO) legislation, which essentially ensures that residents all across the UK have access to phone services at a price they can afford. The UK’s Office of Communications, aka Ofcom, have announced recently that they are in agreement with the government. Since the industry is moving away from the public switched telephone network (PSTN) to IP telephony, the fax machine won’t work the same way.

EV Sales Sticking Point: People Still Want Manual Transmissions

November 15, 2022 by Kristina Panos 258 Comments

Call me crazy, but I’m ride or die for manual transmissions. I drove enough go-karts and played enough Pole Position as a kid to know that shifting the gears yourself is simply where it’s at when it comes to tooling around in anything that isn’t human-powered. After all, manuals can be roll-started. A driver has options other than braking and praying on slippery roads. Any sports car worth its rich Corinthian leather (or whatever) has a manual transmission, right? And you know that Rush’s Red Barchetta ain’t no automatic. Face it, shifting gears is just plain cooler. And it’s not a chore if it gets you more, although the fuel efficiency thing is a myth at this point.

You can imagine then my horror at the idea that someday within my lifetime, most cars will be twist-and-go electric go-karts. As the age of the combustion engine appears to draw to a close (no, seriously this time), there’s just one thing keeping the door open — marked enthusiasm for manual transmissions. From Audi to the Nissan Z, automakers report that the take rate for manual transmissions is quite high in the US, despite the death knell that has been tolling for two decades or so. Two models of Honda Civic are manual-only. This phenomenon isn’t restricted to sports cars, either — the 2022 Ford Bronco comes in a seven-speed manual, and has seen a take rate over 20%.
