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.

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.

The History Of Neon Lights

May 17, 2021 by 12 Comments

We always enjoy history videos from [The History Guy] but they don’t always cover technology history. When they do, though, we enjoy them twice as much as with the recent video he posted on the history of neon signs. Of course, as he points out, many neon lights don’t have actual neon in them — they use various noble gasses depending on the color you want. Sure, some have neon, but the name has stuck.

The back part of the video is more about the signs themselves, but the early portion talks about [William Ramsay], a Scot chemist who started extracting component gasses out of the atmosphere. The first one found was argon and then helium. Krypton and neon were not far behind. The other noble gas, Xenon, also fell to his experiments. He and another scientist won the Nobel for this work.

A Standing Desk On The Cheap

May 17, 2021 by 23 Comments

A programmer forced to work from home during the pandemic, [MrAkpla] was having back pains from sitting in front of the computer all day. He considered buying a standing desk, but all the various options didn’t fit with either his desk or his budget. Not to be deterred, he devised one of the simplest standing desk implementations that we’ve seen. It clearly works for him, because he’s been using it for one year now with great success. [MrAkpla] espouses three main benefits of his approach:

  • Cheap as heck
  • Five minute set up time
  • Uses your existing desk

These goals were accomplished. You can see in the video below that transition from sitting to standing is indeed as quick as he claims, is clearly inexpensive, and indeed it doesn’t require any modifications to his desk or furniture.

This design centers on a having an 80 cm long monitor arm, which is quite a range of adjustment. He’s using a monitor arm pole mount from UK manufacturer Duronic. Although they are having delivery problems these days because of Brexit issues, [MrAkpla] was able to get one delivered from existing inventory outside of the UK.

Admittedly, this is a crude design — in effect two trash bins and a board. But even if this doesn’t fit well with your office decor, its a great way to try out the concept of a standing desk without the up-front investment. By the way, [MrAkpla] is on the lookout for similar monitor mounting poles from non-UK manufacturers. If you have any recommendations, put them in the comments below. If you’re interested in a DIY standing desk that is on the opposite side of the complexity spectrum, check out this beauty that we covered back in the pre-pandemic era.
