Do You Really Own It? Motorcycle Airbag Requires Additional Purchase To Inflate

May 18, 2021 by 218 Comments

If you ride a motorcycle, you may have noticed that the cost of airbag vests has dropped. In one case, something very different is going on here. As reported by Motherboard, you can pick up a KLIM Ai-1 for $400 but the airbag built into it will not function until unlocked with an additional purchase, and a big one at that. So do you really own the vest for $400?

Given the nature of the electronics and computer business lately, we spend a good bit of time thinking of what it means to own a piece of technology. Do you own your cable modem or cell phone if you aren’t allowed to open it up? Do you own a piece of software that wants to call home periodically and won’t let you stop it?  Sometimes it makes sense that you are paying for a service. But there have been times where, for example, a speaker company essentially bricks devices that could work fine on their own even though you — in theory — own the device.

2021 Hackaday Prize Hack Chat; Join Us Live On Wednesday

May 18, 2021 by 1 Comment

Join us on Wednesday, May 19 at noon Pacific for the 2021 Hackaday Prize Hack Chat with Majenta Strongheart!

At this point last year, we probably all felt like we’d been put through a wringer, and that things would get back to normal any day now. Little did we know how much more was in store for us, and how many more challenges would be heaped on our plates. Everything that we thought would be temporary seems to be more or less permanent now, and we’ve all had to adapt to the new facts of life as best we can.

But we’re hackers, and adapting to new situations more often than not means making the world fit our vision. And that’s why the 2021 Hackaday Prize has adopted the theme of “Rethink, Refresh, Rebuild.” We want you to rethink and refresh familiar concepts across the hardware universe, and create the kind of innovation this community is famous for.

The 2021 Hackaday Prize will have it all. As in previous years, the Prize will have several specific challenges, where we set you to work on a creative problem. There will also be mentoring sessions available, $500 cash prizes for 50 finalists along the way, with $25,000 and a Supplyframe Design Lab residency awarded to the Grand Prize winner.

We know you’re going to want to step up to the challenge, so to help get you started, Majenta Strongheart, Head of Design and Partnerships at Supplyframe, will drop by the Hack Chat with all the details on the 2021 Hackaday Prize. Come prepared to pick her brain on how the Prize is going to work this year, find out about the mentoring opportunities, and learn everything there is to know about this year’s competition. It’s the Greatest Hardware Design Challenge on Earth, so make sure you get in on the action.

join-hack-chatOur Hack Chats are live community events in the Hackaday.io Hack Chat group messaging. This week we’ll be sitting down on Wednesday, May 19 at 12:00 PM Pacific time. If time zones have you tied up, 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.

Tiny DeLorean Made From Lighters Is A Total Gas

May 18, 2021 by 29 Comments

There’s making stuff out of trash, and then there’s mind-blowing stuff like this: a DeLorean built from four disposable cigarette lighters and various other bits and bobs like wire sheathing and cotton bud sticks. If it weren’t for the video evidence embedded below, we would have never believed that [Ank Creative] or anyone else could have turned boxy acrylic into the fastback time machine we all know and love.

Is the back window the most important detail? Maybe.

[Ank Creative] seems to have wasted no parts of the lighters, and even saved themselves a bit of trouble by using curved scraps to make the wheel wells. After installing the windshield, we certainly didn’t expect them to saw the thing in half, but how else are they going to put in the little seats and the steering column when the gull-wing doors aren’t real?

This build is all about unbelievable craftsmanship and deft but daring use of hand tools. Although this totally qualifies as an open source how-to video, you’d have to be quite the sorcerer to pull this one off. Zoom past the break (if you haven’t already) and check out this amazing build.

Disposable lighters are dirt cheap, but they get the job done and you can always see how much gas is left in the tank. On the other hand, a refillable lighter is just that, and if you build it yourself, you can make it actuate like a cap gun.

2021 Hackaday Prize: Rethink, Refresh, And Rebuild

May 18, 2021 by 17 Comments

The 2021 Hackaday Prize begins right now. Tap into your creativity and build your piece of a better future on the topics of supportive technology, everyday robotics, imaginative displays, and work-from-home innovations.

Now in its eighth year, the Hackaday Prize is a global engineering initiative that seeks out new and interesting uses of electronics and other technologies with an eye toward open source/open hardware and a goal of getting your creations out into the world.

The grand prize winner will receive $25,000 and a residency at the Supplyframe Design Lab. In addition to top prizes for the second through fifth place winners, 50 finalists will each receive a $500 prize. But you don’t need to win the Hackaday Prize to take something away. This is your calling: spend time working on those abstract ideas and figuring out how they will fit into life tomorrow, next month, or next decade. Whether it changes peoples’ lives or just brings a smile to a few faces, every interesting step forward is an example where people had ideas so crazy they actually worked. Let’s get in on that!

There are five categories to target with your builds. If you have an idea kicking around, you can probably enter it this year.

Spy Tech: CIA Masks In Five Minutes Or Less

May 18, 2021 by 23 Comments

You know the old trope: James Bond is killed but it turns out to be someone else in an incredibly good-looking Sean Connery mask. Mission: Impossible and Scooby Doo regularly had some variation of the theme. But, apparently, truth is stranger than fiction. The CIA has — or at least had — a chief of disguise. A former holder of that office now works for the International Spy Museum and has some very interesting stories about the real masks CIA operatives would use in the field.

According to the video you can see below, the agency enlisted the help of Hollywood — particularly the mask maker from Planet of the Apes — to help them with this project. Of course, in the movies, you can take hours to apply a mask and control how it is lit, how closely the camera examines it, and if something goes wrong you just redo the scene. If you are buying secret plans and your nose falls off, it would probably be hard to explain.

Retro ISA Card Means Old, Slow Computers No Longer Need Old, Heavy Monitors

May 18, 2021 by 66 Comments

One thing about vintage computers is that they depend greatly on whether or not one can plug a compatible monitor into them. That’s what’s behind [Tube Time]’s Graphics Gremlin, a modern-design retro ISA video card that uses an FPGA to act just like a vintage MDA or CGA video card on the input end, but provides a VGA port for more modern display output options. (Actually, there is also an RGBI connector and a composite video out, but the VGA is probably the most broadly useful.)

Handy silkscreen labels make everything crystal clear. Click to enlarge.

Why bother making a new device to emulate an old ISA video card when actual vintage video cards are still plentiful? Because availability of the old cards isn’t the bottleneck. The trouble is that MDA or CGA monitors just aren’t as easy to come across as they once were, and irreplaceable vintage monitors that do still exist risk getting smashed during shipping. Luckily, VGA monitors (or at least converters that accept VGA input) are far more plentiful.

The board’s design files and assembly notes are all on the project’s GitHub repository along with plenty of thoughtful detail about both assembly and troubleshooting, and the Verilog code has its own document. The Graphics Gremlin is still under development, but you can also watch for the latest on [Tube Time]’s Twitter feed.

Thanks to [NoxiousPluK] for the tip!

A “Disgusting” 1980s Computer Restored

May 17, 2021 by 42 Comments

It takes a special eye to see a junkyard car and envision it as your latest hotrod. The guys at RMC found what they termed a “disgusting” Acorn Electron and decided to restore it to its former glory. The Electron was a budget version of the BBC micro with a 6502 running at 2 MHz when executing code from ROM and 1 MHz when it hit the RAM. Apparently, at least some of the bus was operating at 4 bits instead of 8. Go figure.

The 1982 machine was meant to head off the Sinclair ZX and was set to sell for about £200. However, the machine didn’t catch on like the Sinclair and undersold it by around 20 times with a paltry quarter of a million units.
