A few days ago the source code for the popular Winamp music player was released into the world, with as we reported at the time, a licence that left a lot to be desired. Since then it seems some of the criticism has caught up with the company, for not only have they modified their terms to allow forking, they’ve reacted to a bunch of claimed GPL violations by removing offending files. Perhaps How-To-Geek are right in describing it all as an absolute mess.
The forking amendment means that with luck we’ll start seeing a few modified players descending from the Winamp code, and it seems that the GPL violations are more embarrassing technicalities than show-stoppers, but we have to wornder whether or not this makes for something with any more than historical interest. Perhaps its value stands in a lesson for corporate entities in how not to release their source, which sadly we expect will be taken by other organisations as an excuse not to do so.
[Zibartas] recently created wearable helmets from the game Starfield that look fantastic, and we’re happy to see that he created a video showcasing the whole process of design, manufacture, and assembly. The video really highlights just how much good old-fashioned manual work like sanding goes into getting good results, even in an era where fancy modern equipment like 3D printing is available to just about anyone.
The secret to perfectly-tinted and glassy-smooth clear visors? Lots and lots of sanding and polishing.
The visor, for example, is one such example. The usual approach to making a custom helmet visor (like for Daft Punk helmet builds) is some kind of thermoforming. However, the Starfield helmet visors were poor candidates due to their shape and color. [Zibartas]’s solution was to 3D print the whole visor in custom-tinted resin, followed by lots and lots of sanding and polishing to obtain a clear and glassy-smooth end product.
A lot of patient sanding ended up being necessary for other reasons as well. Each helmet has a staggering number of individual parts, most of which are 3D printed with resin, and these parts didn’t always fit together perfectly well.
[Zibartas] also ended up spending a lot of time troubleshooting an issue that many of us might have had an easier time recognizing and addressing. The helmet cleverly integrates a faux-neon style RGB LED strip for internal lighting, but the LED strip would glitch out when the ventilation fan was turned on. The solution after a lot of troubleshooting ended up being simple decoupling capacitors, helping to isolate the microcontrollers built into the LED strip from the inductive load of the motors.
What [Zibartas] may have lacked in the finer points of electronics, he certainly makes up for in practical experience when it comes to wearable pieces like these. The helmets look solid but are in fact full of open spaces and hollow, porous surfaces. This makes them more challenging to design and assemble, but it pays off in spades when worn. The helmets not only look great, but allow a huge amount of airflow. This along with the fans makes them comfortable to wear as well as prevents the face shield from misting up from the wearer’s breathing. It’s a real work of art, so check out the build video, embedded just below.
[Project 326] wanted to know exactly what gas was in some glass tubes. The answer, of course, is to use a spectrometer, but that’s an expensive piece of gear, right? Not really. Sure, these cheap devices aren’t perfect, but they are serviceable and, as the video below shows, there are ways to work around some of the limitations.
The two units in question are “The Little Garden” spectrometer and a TLM-2. Neither are especially sensitive, but both are well under $100, so you can’t expect much. Because the spectrometers were not very sensitive, a 3D printed jig and lens were used to collect more light and block ambient light interference. The jigs also allowed the inclusion of special filters, which enhanced performance quite a bit. The neon bulbs give off the greatest glow when exposed to high voltage. Other bulbs contain things like helium, xenon, and carbon dioxide. There were also tubes with mercury vapor and even deuterium.
We’ll admit it. Not everyone needs a spectrometer, but if you do, there’s a lot of really interesting info on how to get the most out of these cheap devices. Apparently, [Project 326] was frustrated that he couldn’t buy an X-ray spectrometer and has vowed to create one, so we’ll be interested to see how that goes.
The software defined radio has opened up unimaginable uses of the radio spectrum for radio enthusiasts, but it’s fair to say that there’s one useful feature of an old-fashioned radio they lack when used via a computer. We’re talking of course about the tuning knob, because it represents possibly the most intuitive way to move across the bands. Never fear though, because [mircemk] has a solution. He’s converted a mouse into a tuning dial.
The scroll wheel on a mouse is nothing more than a rotary encoder, and can easily be used as a sort of tuning knob. Replacing it with a better encoder gives it a much better feel, so that’s what he’s done. An enclosure has the guts of a mouse, with the front-mounted encoder wired into where the scroll wheel would have been. The result, for a relatively small amount of work, is a tuning knob, and a peripheral we’re guessing could also have a lot of uses beyond software defined radio.
It’s not the first knob we’ve seen, for that you might want to start with the wonderfully named Tiny Knob, but it’s quite possibly one of the simplest to build. We like it.
[Ben] may be 15 years old, but he’s got the knack for 3D printing and artistic mechanical design. When you see his 3D-printed mechanical jellyfish lamp, we think you’ll agree. Honestly, it is hardly fair to call it a lamp. It is really — as [Ben] points out — a kinetic sculpture.
One of the high points of the post is the very detailed documentation. Not only is everything explained, but there is quite a bit of background information on jellyfish, different types of gears, and optimizing 3D prints along with information on how to recreate the sculpture.
There is quite a bit of printing, including the tentacles. There are a few options, like Arduino-controlled LEDs. However, the heart of the operation is a geared motor.
All the design files for 3D printing and the Arduino code are in the post. There’s also a remote control. The design allows you to have different colors for various pieces and easily swap them with a screwdriver.
One major concern was how noisy the thing would be with a spinning motor. According to [Ben], the noise level is about 33 dB, which is about what a whisper sounds like. However, he mentions you could consider using ball bearings, quieter motors, or different types of gears to get the noise down even further.
We imagine this jellyfish will come in at well under $6 million. If you don’t want your jellyfish to be art, maybe you’d prefer one that creates art.
These days everything needs to be connected to remote servers via the internet, whether it’s one’s TV, fridge or even that new car you just bought. A recently discovered (and already patched) vulnerability concerning Kia cars was a doozy in this regard, as a fairly straightforward series of steps allowed for any attacker to obtain the vehicle identification number (VIN) from the license plate, and from there become registered as the car’s owner on Kia’s network. The hack and the way it was discovered is described in great detail on [Sam Curry]’s website, along with the timeline of its discovery.
Notable is that this isn’t the first vulnerability discovered in Kia’s HTTP-based APIs, with [Sam] this time taking a poke at the dealer endpoints. To his surprise, he was able to register as a dealer and obtain a valid session ID using which he could then proceed to query Kia’s systems for a user’s registered email address and phone number.
With a specially crafted tool to automate the entire process, this information was then used to demote the car’s owner and register the attacker as the primary owner. After this the attacker was free to lock/unlock the doors, honk to his heart’s content, locate the car and start/stop the vehicle. The vulnerability affected all Kia cars made after 2013, with the victim having no indication of their vehicle having been hijacked in this manner. Aside from the doors randomly locking, the quaint honking and engine turning on/off at a whim, of course.
Perhaps the scariest part about this kind of vulnerability is that it could have allowed an attacker to identify a vulnerable parked car, gained access, before getting into the car, starting the engine and driving away. As long as these remote APIs allow for such levels of control, one might hope that one day car manufacturers will take security somewhat more serious, as this is only the latest in a seemingly endless series of amusingly terrifying security vulnerabilities that require nothing more than some bored hackers with HTTP query crafting tools to discover.
For some of us, the Speak ‘n Spell evokes pleasant memories of childhood as our first computer, along with one of those Merlin things. For others, it’s the ultimate circuit bending victim. For [Jeremy Geppert], they’re all-around good fun and he wanted to immortalize the device in a Simple Add-On (SAO).
This is [Jeremy]’s first board and SAO rolled into one, motivated by both Supercon and the SAO Contest. To start things off, [Jeremy] scaled down the design we all know and love to fit a 128×32 OLED display, and it looks great. The plan is to have the display, an amplified speaker, and a single button for input.
Before committing the board order, [Jeremy] had a brief freak-out about the pin distance as it relates to the window for the OLED display. Luckily, his brother suggested checking things first by printing a 1:1 scale image of the board outline, and laying that over the display.
This is the week it all comes together, as the tiny switches and (regular-size) connectors have arrived, and the boards are due quite soon. Go, [Jeremy], go!
