The better you look the more you will be in awe of this shockingly intricate 777 replica. The fully-articulating landing gear alone has over 2,000 parts as well as 200 hours of assembly, not even including the penny-sized tires with individually-cut carry nuts. All carved from manilla office folders by hand.

A high institution art architecture class in 2008 influenced this develop by mentor a few papercrafting techniques. When [Luca] got a hold of a precision Air India 777-300ER schematic, he started building this 5 foot long 1:60 scale model. His project has got a fair amount of media interest over the years, including some false reports that he was so focused on the develop that he dropped out of college (he did, for 2 years, however for other reasons). 6.5 years in the making, [Luca] is rounding the homestretch.

The style is manually drawn in Illustrator from the schematics, then is printed directly onto the manilla folders. Wielding an X-acto knife like a watch-maker, [Luca] cuts all the segments out as well as locations them with whispers of glue. Pistons. Axles. Clamps. tie rods. Brackets. even pneumatic hoses – fractions of a toothpick thin – are run to their appropriate locations. A fit together behind the engine was latticed manually from of numerous strands. If that was not enough, everything moves as well as works precisely as it does on the genuine thing.

Tires really swing as well as steer. landing gear really collapses as well as folds up. The flaps move. The engines are not just splendid static replicas; the 777 has a collapsible rear section for reverse thrust as well as so does [Luca]’s manilla version. The cabin as well as cargo doors hinge as well as lock into place. even the bathrooms are just as cramped as you keep in mind them being.

[Luca] spent a whole summertime just on the furniture: the 300+ economic climate seats took him 20 minutes each, two business class seats might be completed in a day, as well as a single very first class suite was a full 8 hour shift. The engines took one more five months. The galley as well has lots of detail – row after row of carts as well as cabinets.

It is not just the precision, meticulousness, as well as detail that impresses – the infinitesimal scale defies belief. The private cockpit controls are each dwarfed by the grooves of their maker’s fingerprints. See the video embedded below of the primary landing gear retracting as well as note the whole assemblies manipulated by tweezers. just like the genuine thing the gear is little however strong, it can support a number of times the weight of the completed jet.

Expecting to be total later this year (though he stated the exact same thing last year), [Luca] has already started painting the fuselage. After he is done he plans to one-up himself with a 20 foot version.

[Luca] does not have a job page per se however he documents well. He even spent two weeks editing 130 hours of time-lapse footage for his fans to appreciate the work that goes into a single assembly. For all the glorious details see his Flickr albums or his Youtube channel.

Thanks [Lars] for the tip.

* Corrected, it was an design class, not an art class.

Oftentimes, the function set for our typical fitness-focused wearables feels a bit empty. push notifications on your wrist? OK, fine. Counting your steps? Sure, why not. however exactly how useful are those abilities anyway? Well, what if wearables might be utilized for a more dignified function like assisting people in healing from compound utilize condition (SUD)? That’s what the researchers at the university of Massachusetts medical institution aimed to discover out.

In their paper, they utilized a wrist-worn wearable to determine locomotion, heart rate, skin temperature, as well as electrodermal activity of 38 SUD patients during their daily lives. They wished to find periods of stress as well as craving, as these parameters are possible triggers of compound use. Furthermore, they had patients self-report times during the day when they felt stressed or had cravings, as well as utilized those reports to calibrate their model.

They tried a number of classification designs such as decision trees, discriminant analysis, logistic regression, as well as others, however discovered the most success utilizing support vector machines though they failed to discuss why they believed that was the case. In the end, they discovered that they might find stress vs. non-stress with an accuracy of 81.3% as well as craving vs. no-craving with an accuracy of 82.1%. Not amazing accuracy, however provided the dire requirement for medical advancements for SUD, it’s something to keep an eye on. Interestingly enough, they discovered that locomotion data alone had an accuracy of approximately 75% when it came to indicating stress as well as cravings.

Much ado has been made about the insufficient accuracy of wearable gadgets for medical diagnoses, especially of those that determine activity as well as heart rate. perhaps their design would perform better, being trained on real-time measurements of cortisol, a more precise physiological determine of stress.

Finally, what truly stood out to us about this research study was exactly how willing patients were to utilize a wearable in their treatment strategy. It’s unfortunate that society frequently has a extremely unfavorable understanding of SUD patients, leading to fewer treatment choices for patients. however hopefully, with technological advancements such as this, we’re one step better to a more equitable future of healthcare.

considering that Google announced the Nexus Q media streaming device at the Google developers conference a few weeks ago, a lot of devs have been toying around with the idea of running Android apps on this small media sphere. [Det] over at BrickSimple threw his hat into the ring with a Pong and/or Breakout app that showcases the substantial rotary volume knob on the Q.

The Nexus Q was hacked into running proper Android apps not long after it made its way into the hands of Google IO conference attendees. Of course with no way to get user input into Google’s little sphere, that hack was of questionable utility. Recently, [kornyone] over on the XDA developers forum got USB HID input on the Q, allowing for full mouse and keyboard support.

Not much has been said about the Q’s most prominent physical feature, the half hemisphere rotary encoder that serves as the volume knob. To build his Pong/Breakout clone, [Det]’s app simply responds to volume up/volume down events by moving the paddle to the left or right.

A neat build, and hopefully we’ll see a few a lot more Nexus Q hacks in short order.

in some cases a terrific hack is terrific for no other reason than that it’s fun, and [Michael Rechtin]’s diy active Aero Spoiler and Air Brake certainly qualifies as a fun hack. This is a mod developed to live in a world where looks are everything, stickers add horsepower, and a good sound system is much more essential than good wheel alignment. Why is that? because like the switch that exists only to activate the mechanism that turns it off, the diy active Aero Spoiler and Air Brake seen below is practically completely useless. So to understand its allure, we should understand its inspiration.

For a few decades now, luxury sports automobile producers have been adding active aerodynamic elements to their vehicles. For example, several Porsche designs feature adaptive spoilers that adjust to driving conditions. very cars and trucks such as the Bugatti Veyron have spoilers that flip up at high angles during braking to increase drag and decrease braking distance. all of these features are unfortunately missing from the average two or four door family-car-turned-wannabe-track-fiend. until now!

[Michael] has created a new active spoiler for each mall-bound muffler-challenged hand me down. The build starts with a CNC cut foam wing which is covered with fiberglass, Bondo (an automotive necessity) and some synthetic carbon fiber for that go-fast feel. An Arduino, IMU, two servos, and a battery pack discover deceleration and immediately increase the spoiler angle just like the big boys, but without needing any integration into the cars systems. Or bolts, for that matter.

It’s unlikely that the braking force is enough to slow down the car though, given that it’s not enough to pop the suction cups holding it to the trunk lid. but does it have the “wow” element that it was developed to induce? Spoiler Alert: It does!

As it turns out, this isn’t the first adjustable spoiler featured here at Hackaday, and this adjustable spoiler on a automobile that’s produced actual racing is quite interesting.

Thanks to [Zane] for the suggestion on this project!

If you can’t envision composing a letter on a typewriter as well as putting it in a mailbox, then you take computers for granted. however that’s just the suggestion of the iceberg. much more niche applications begat niche machines, as well as a number of them are on screen in this film that the computer history Archives job released last month. aside from the File-o-matic Desk, the Addressograph, or the noise Scriber, there a number of other gadgets that provide us a peek into a bygone era.

One device that’s still around, although in a much computerized form, is the stenograph. Not so prominent these days is the practical stenograph carrier, enabling a patient’s statement to be recorded bedside in the medical facility promptly after a cars and truck accident. cable recorders were all popular in 1947, as were floppy disks (for audio, not data). Both media were utilized to time-shift dictation. Typing champions like Stella Pajunas might transcribe your letters as well as memos at 140 WPM utilizing an electric typewriter, outpacing dot matrix printers however a snail’s speed compared to a laser jet.

Typing ten Feet Wide

Before the IBM Selectric as well as its changeable font style balls, there was the Varityper. It was a advanced typewriter supporting several font styles as well as proportional spacing. An unusual one is shown here, utilized for typing notes on engineering drawings as well as maps as much as ten feet wide, in different font styles as well as sizes.

Chinese Typewriter is ingenious however Flops

Next we have the IBM electronic Chinese typewriter, the innovation of IBM Rochester engineer [Kao Chung-Chin] (US patent 2,412,777, Dec 1946). In his design, [Kao]’s service to dealing with countless Chinese glyphs is not a monster keyboard. Rather, he needs the typist to go into a four-digit code utilizing a moderate number of keys. In contemporary terms, this would be like typing your file utilizing Unicode values on a numeric keypad. in spite of this impediment, IBM worker [Lois Lew] handled a respectable 45 WPM on this behemoth. as well as unlike the typewriter project, which was cancelled, [Lois] is still to life as well as kicking in Rochester. She just recently linked with Stanford university professor [Thomas Mullaney] who is a researcher in Chinese history as well as focuses on typewriters. You can checked out his piece on this typewriter’s history as well as [Lois]’s involvement with the job in this short article he composed back in May.

Addressograph Cards Are Still Available
I recognized, as well as really utilized a few of the products featured in this film. My father’s workplace, where I would in some cases hang out after school, had a few of these machines back in the 1970s. the most spectacular was the Addressograph system, utilized to prepare mailings for newsletters, publish cards, etc. It was essentially a mechanical database. Each person was represented by a special card, prepared by a Graphotype machine, a specialized typewriter that embosses text on little metal plates, not unlike a dog-tag. The card was really a frame, which held the embossed plate, a piece of card stock with the info typed by traditional means, as well as a series of slots along the top of the card which might hold metal tabs. These tabs denoted different user-defined categories. In an engineering company, for example, you might assign tab positions for every department, for every building, for every job team, etc. The entire business roster is now contained in one or much more filing drawers, each about the size of an old-fashioned library card catalog drawer.

When you want to send out a letter to all the mechanical engineers working in the Poughkeepsie office, the operator would set up the Addressograph device accordingly. The stack of cards from each drawer is slid into the feed rack, as well as each card is conveyed one-by-one with the device for printing. only those cards whose tabs match the configuration are printed onto the envelopes. Cards not chosen for the mailing would be passed over. After some time, my father realized that each drawer had its own quirks as well as temperament, so he provided each of them names.

Pedro might always be counted upon to misbehave.

These machines needed a bit of maintenance to keep running, however they were developed like a tank. The ones I encountered as a teenager were bought in the late 1940s as well as kept operational up until the early 1980s, when other inexpensive choices ended up being viable. That seems like a long time today, when office devices has lifespans determined in years not decades. in spite of getting the task done, such single-purpose specialized office machines have all however vanished from the common office these days. as well as no question — practically every function featured in this film can be done today with a desktop computer as well as a multifunction printer / scanner.

Check out the the video below the break. Are you still utilizing any type of obsolete office devices today? let us understand in the comments below.

[Robert Murray-Smith] wanted to recreate exactly how some ancient microscopes worked: with a decrease of water as a lens. The concept is that the meniscus of a decrease of water will work as a lens. This works since of surface tension as well as by controlling the attraction of the water to the surface,  you can really type convex as well as concave surfaces.

What’s fascinating is that this doesn’t need a great deal of equipment. Some plastic, a hole punch, some pens, a flashlight, as well as some other chances as well as ends. then it’s just a matter of grabbing some puddle water as well as examining the critters inside. Of course, with a single lens, these are more properly magnifying glasses. Some insurance claim that people in China built such instruments thousands of years ago. [Robert] mentions [Antonie van Leeuwenhoek] as the father of the microscope, although he wasn’t the very first to develop such a device. He did produce outstanding glass lenses utilizing a technique he kept trick however has been worked out utilizing contemporary science.

It is difficult to see much with the camera, however it clearly was magnifying. Not a poor little rainy day kid’s job since you most likely have whatever you requirement on hand. We question what other readily-available things you might picture with a gadget like this.

Of course, if you want to develop a genuine microscope, the styles are out there. You can even make one utilizing — mainly — LEGO.

exactly how do you look back over your life as well as divide it up? perhaps by decades, cultural moments, or geopolitical events. For radio amateurs with older callsigns there’s a temptation to do so by solar cycles, as the approximately 11-year period of the Sun’s activity had a big impact on radio propagation with the fee it produces in the upper atmosphere. We’re now in solar cycle 25, numbered considering that the 18th century when the science of solar observation began, as well as as never before we’re surrounded by info from professionals such as [Dr. Tamitha Skov], the so-called [Space weather condition Woman]. When she states something is on the method we listen, so a recent Tweet predicting a direct hit from a solar storm with a great probability of auroras in lower latitudes is extremely much worth sharing.

We need to prolong our commiserations to visitors in equatorial climes as well as ever with the lower half of the USA, southern Europe, the middle East, India, Japan, as well as China. You won’t see the aurora we’ll catch in Europe together with our buddies in new Zealand, Canada, Russia, as well as northern USA. however even then to those of us at moderate latitudes an aurora is a quite unusual event, so we’re expecting remove skies on the 2nd of February as well as would recommend you to look out as well if you’re in the likely zone even if they won’t be rather as excellent as those in our header picture. on the other hand radio amateurs all over don’t have to see quite lights in the sky to reap the benefits in terms of propagation, so delighted DX hunting! The Tweet is embedded below the break, so you can play the timeline for yourselves.

Ah, Google. very few companies have mastered the art of creating remarkable technology and products, and then so successfully abandoning and mishandling them. case in point, YouTube. Citing “dislike attacks”, which are coordinated down-voting of particular videos, YouTube opted to hide the dislike counter on all videos. It could be pointed out that dislikes still impact the recommendation algorithm the same way they always have, and that creators still see their dislike counts on their own dashboard.

There might be something to the idea that YouTube doesn’t like the notoriety of their Rewind videos leading the dislike count, with 2018 at nearly 20 million. There may even be validity in the theory that corporate partners don’t like visible dislike numbers on their videos. Regardless, YouTube made the change, and people hate it. Their platform, so nothing you can do about it, right?

“Life, uh, uh, finds a way,” to quote my favorite fictional mathematician. Yes, a hacker, one of us, has figured out a workaround. [Dmitrii Selivanov] has put together the “Return YouTube Dislike” browser extension, which does a couple of things. First, it is pulling archived data about videos, taking advantage of the gap in time between the official announcement, and the removal of the dislike API.

But for new videos? That’s where things are harder. If you install the extension, your video likes and dislikes are tracked, and the combined user data is used to extrapolate an estimated dislike count on any given video. [Dimitrii] is also working on a way to allow individual channels to share their stats with the project, to give a lot more official numbers for their videos.

The extension is open source, and the Chrome web store shows over a million users. Linus tech Tips, along with a bunch of other channels, have covered this, so check out their videos for more.

Impressed by this bit of browser hacking? You can make an entire office suite in the browser as well!

Often, we requirement to power a 5V-craving job of ours on the go. So did [Burgduino], and, dissatisfied with services available, developed their own 5V UPS! It takes a inexpensive powerbank style as well as augments it with a few parts important for its UPS purposes.

You may be lured to reach for a powerbank when dealing with such a problem, however many of them have a fatal flaw, as well as you can’t quickly tell a flawed one aside from a working one before you purchase it. This flaw is lack of tons sharing – capability to continue powering the output when a charger is inserted. many store-bought powerbanks just shut the output off, which precludes a job running 24/7 without powering it down, as well as can cause adverse consequences when something like a Raspberry Pi is involved.

Understandably, [Burgduino] wasn’t alright with that. Their UPS is based on the TP5400, a integrated LiIon charging as well as increase chip, utilized a great deal in easy powerbanks, however not capable of tons sharing. For that, an additional LM66100 chip – an “ideal diode” controller is used. You may scoff at it being a Texas Instruments part, however it does seem to be commonly offered as well as only a tad much more costly than the TP5400 itself! The style is open hardware, with PCB data offered on EasyEDA as well as the BOM clearly laid out for simple LCSC ordering.

We the hackers may struggle to keep our portable Pi jobs powered, employing supercapacitors as well as modifying terribly developed Chinese boards. However, when we discover a appropriate toolkit for our purposes, battery-powered jobs tend to open new frontiers – you may even go beyond your Pi as well as upgrade your router with an UPS addon! Of course, it’s not always smooth sailing, as well as in some cases seemingly portability-friendly gadgets can surprise you with their style quirks.

It’s a special gut-dropping, grumbly moment that a lot of who use 3d printers know all too well. When you check on your 13-hour print, only to see that it failed printing several hundred layers ago. [Stephan] from [CNC Kitchen] has a few creative tricks to resume failed prints.

It starts when you discover your print has failed and whether the part is still attached to the bed. If it has detached, the best you can do is whip out your calipers to get a reasonably accurate measurement of how much has been printed. then slice off the already printed section, print the remainder, and glue the two parts together. If your part is attached to your print bed and you haven’t shifted the plate (if it is removable), start by removing any blemishes on the top layer. That will make it smooth and predictable as it’s starting a new print, just on top of an existing one. Measuring the height that has been printed is difficult considering that you cannot remove it. Calipers of sufficient length can use their depth function, but you might also be able to do a visual inspection if the geometry is special enough. After you load up your model in a G-Code viewer, go through it layer by layer until you find what matches what has already been printed.

The last (and maybe a lot of clever) is to use the printer as a makeshift CMM (coordinate measuring machine). You manually step the printer until it touches the top of the part, then read the z-axis height by means of a screen or M114 command. A quick edit to the raw G-Code gives you a new file that will resume precisely what it was doing before. If you can’t rehome because the head can’t clear the part, [Stephan] walks you through setting the home on your printer manually.

If all the doesn’t work, and the print is still unrecoverable, maybe you can look into recycling the plastic into new filament.
