Hackaday Links: February 9, 2020

In case you thought that we learned everything we need to know to land on the Moon fifty years ago, think again. NASA still has a lot of questions, and has scheduled the first of many commercial missions designed to fill in the blanks. As part of the Artemis program, which aims to land the first women and the next men on the Moon by 2024, NASA’s Commercial Lunar Payload Service (CLPS) will send 16 science payloads to the Moon via two separate commercial flights. The two companies, Astrobotics and Intuitive Machines, will send landers to the Moon in 2021 using a ULA Vulcan Centaur and a SpaceX Falcon 9, respectively. Fourteen companies were selected for CLPS, and with much to learn (or relearn) about landing and working on the Moon, watch for many more flights in the years to come. We’re all for the commercialization of space, but we have to admit that things were easier to keep track of when space exploration was a little more monolithic.

It looks like millions of BlackBerry phone users will have to find something else to do with their thumbs now that TCL is getting out of the BlackBerry business. The Chinese company announced this week that they would no longer have the rights to manufacture BlackBerry-branded phones like the Key2 as of August 31, 2020. Crackberry addicts were understandably upset, but all may not be lost for those who can’t stand the virtual keyboards on most other smartphones, as there’s still a chance another manufacturer will step in to fill the void.

Hypothetical situation: You’re in need of a car, so you go to a used car dealer. You see a nice car, take it for a test drive, and decide to buy it. Money is exchanged, paperwork done, and the salesman hands you the keys. You go out to the lot to drive your new ride home only to find out that the mechanic has removed the tires. When you ask what the deal is, the salesman says, “Sorry, you didn’t buy a license for the tires.” Hypothetical perhaps, but not far off from what happened to one Tesla Model S buyer when an over-the-air update disabled the Enhanced Autopilot and Full Self-Driving features he paid for. Tesla didn’t see it that way, though, claiming that he’d need to pony up to use the new features, which originally sold for $8,000. It raises interesting questions about how the secondary automotive market will respond to the increasingly complicated relationship between hardware and software, and what you’re actually paying for when you buy a car.

Back in the early days of Bitcoin, skeptics used to dismiss the cryptocurrency by saying, “When you can pay your taxes with it, then it’s real money.” Well, that day is apparently here for the municipality of Zermatt in Switzerland, where it was announced that Bitcoin will be accepted as payment for local taxes and other official fees. The Zermatt city hall has installed a Bitcoin point-of-sale terminal, or payments can be made directly from a Bitcoin wallet after filling out the proper paperwork. Bitcoin as legal tender for public debts is not exactly new; Ohio was doing it back as far as 2018. But we find the economic implications of this interesting — as our resident econometrician [Elliot Williams] pointed out, paying taxes in anything but the national currency was considered preposterous not that long ago.

Hackaday Podcast 053: 1-Bit Computer Is A Family Affair, This Displays Is Actually Fabulous, And This Hoverboard Is A Drill Press

February 7, 2020 by Mike Szczys 3 Comments

Hackaday editors Mike Szczys and Elliot Williams navigate the crowded streets of the hackersphere for the most interesting hardware projects seen in the past week. Forget flip-dot displays, you need to build yourself a sequin display that uses a robot finger and sequin-covered fabric to send a message. You can do a lot (and learn a lot) with a 1-bit computer called the WDR-1. It’s never been easier to turn a USB port into an embedded systems dev kit by using these FTDI and Bluepill tricks. And there’s a Soyuz hardware teardown you don’t want to miss.

This Week In Security: Google Photos, Whatsapp, And Doom On Deskphones

February 7, 2020 by Jonathan Bennett 12 Comments

Google Photos is handy. You take pictures and videos on your cell phone, and they automatically upload to the cloud. If you’re anything like me, however, every snap comes with a self-reminder that “the cloud” is a fancy name for someone else’s server. What could possibly go wrong? How about some of your videos randomly included in another user’s downloads?

Confirmed by Google themselves, this bug hit those using Google Takeout, the service that allows you to download all your data from a Google application, as a single archive. Google Photos archives downloaded between November 21 and November 25 may contain videos from other users, according to a notice sent to the users who downloaded said archives. It’s notable that those notices haven’t been sent to users who’s videos were exposed.

Dutch Hackerspaces At Ten Years Old: Celebrating A Community With A Special Map

February 6, 2020 by Jenny List 4 Comments

The exotic cruise destination of Hoek van Holland Haven.

A couple of months ago I wrote a piece about the evolution of hackerspaces, and mentioned that I’d be attending a party for a hackerspace birthday. As I write this that party was last weekend, and it was celebrating both the birthday of RevSpace in the Hague, and the tenth anniversary of hackerspaces in the Netherlands. After a relaxing ocean cruise across the North Sea and a speedy train ride I found myself in RevSpace with a bottle of Club-Mate in my hand, hanging out with not only the locals but a selection of others from all across northwestern Europe and beyond. RevSpace is an exceptionally well-organised hackerspace with a large membership, so there was plenty to talk about and a lot of interesting projects to look at.

There was a short programme of talks in Dutch, covering hackerspace history and interviewing a panel of hackerspace founders. I am told that these may make their way online with an English translation in due course, and should be worth looking out for. Then there was an epic-scale barbecue, an old-school rave with Gameboy chiptunes and analogue synth EDM among other delights, and the chance for an evening’s socialising with the rest of the attendees.

The $50 Ham: Going Mobile

February 5, 2020 by Dan Maloney 34 Comments

So far in this series, everything we’ve covered has been geared around the cheapest and easiest possible means of getting on the air: getting your Technician license, buying your first low-end portable transceiver, and checking in on the local repeater nets. That’s all good stuff, and chances are you can actually take all three of those steps and still have change left over from your $50 bill. Like I said, amateur radio doesn’t have to be expensive to be fun.

But at some point, every new ham is going to yearn for that first “real” rig, something with a little more oomph in terms of power, and perhaps with a few more features. For many Technicians, the obvious choice is a mobile rig, something that can be used to chat with fellow hams on the way to work, or to pass the time while on long road trips. Whatever your motivation is, once you buy a radio, you have to install it, and therein lie challenges galore, both electrical and mechanical.

I recently took the plunge on a mobile rig, and while the radio and antenna were an order of magnitude more expensive than $50, the process of installing it was pretty cheap. But it’s not the price of the thing that’s important in this series; rather, it’s to show that ham radio is all about doing it yourself, even when that means tearing your car apart from the inside out and rebuilding it around a radio.

Linux Fu: The Linux Shuffle

February 3, 2020 by Al Williams 35 Comments

Computers are known to be precise and — usually — repeatable. That’s why it is so hard to get something that seems random out of them. Yet random things are great for games, encryption, and multimedia. Who wants the same order of a playlist or slide show every time?

It is very hard to get truly random numbers, but for a lot of cases, it isn’t that important. Even better, if you programming or using a scripting language, there are lots of things that you can use to get some degree of randomness that is sufficient for many purposes.

Keeping Ham Radio Relevant Hack Chat

February 3, 2020 by Dan Maloney 69 Comments

Join us on Wednesday, February 5 at noon Pacific for the Keeping Ham Radio Relevant Hack Chat with Josh Nass!

It may not seem like it, but amateur radio is fighting a two-front war for its continued existence. On the spectrum side, hams face the constant threat that the precious scraps of spectrum that are still allocated to their use will be reclaimed and sold off to the highest bidder as new communication technologies are developed. On the demographic side, amateur radio is aging, with fewer and fewer young people interested in doing the work needed to get licensed, with fewer still having the means to get on the air.

Amateur radio has a long, rich history, but gone are the days when hams can claim their hobby is sacrosanct because it provides communications in an emergency. Resting on that particular laurel will not win the hobby new adherents or help it hold onto its spectrum allocations, so Josh Nass (KI6NAZ) is helping change the conversation. Josh is an engineer and radio amateur from Southern California who runs Ham Radio Crash Course, a YouTube channel dedicated to getting people up to speed on ham radio. Josh’s weekly livestreams and his video reviews of ham radio products and projects show a different side of the World’s Greatest Hobby, one that’s more active (through events like “Summits on the Air”) and focused on digital modes that are perhaps more interesting and accessible to new hams.

Join us on the Hack Chat as we discuss how to make ham radio matter in today’s world of pervasive technology. We’ll talk about the challenges facing amateur radio, the fun that’s still to be had on the air even when the bands are dead like they are now (spoiler alert: they’re not really), and what we can all do to keep ham radio relevant.

Our Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, February 5 at 12:00 PM Pacific time. If time zones have got you down, we have a handy time zone converter.

Click that speech bubble to the right, and you’ll be taken directly to the Hack Chat group on Hackaday.io. You don’t have to wait until Wednesday; join whenever you want and you can see what the community is talking about. Continue reading “Keeping Ham Radio Relevant Hack Chat” →
