Hack a Day
Sometimes you need something really flashy to complete an outfit. Whether it’s a sparkly pair of earrings or a stylish necklace, accessories are key to competing on the fashion battlefield. For those who want to bring some serious firepower, [p3nguin’s] laser crown might be just what the doctor ordered.
At the outset, we should state the crown only uses lasers in its construction, for cutting felt and acrylic. The light source is a Neopixel ring from Adafruit, capable of bringing the vibrant colors without risk of eye damage. The ring is then assembled with a series of snap-together acrylic parts and a felt cap, with slots for hair pins to keep the crown in place on the wearer’s head. A Trinket drives the show, with a LiPo battery used as a lightweight power supply.
It’s a nice build that’s sure to draw plenty of attention. We see some great wearables around these parts; this EL jacket is a particular favorite. Video after the break.

Some people get inked, while others get henna or those water transfer tattoos you might find in a box of Cracker Jack. [Becky] wanted the benefits of having an RFID tag in her finger — unlock doors or log into your computer with a swipe of your finger — but wasn’t ready to get an implant. Her solution: make an artistic ring that conceals a tiny glass capsule RFID tag.
Besides not having to shove some tech under your epidermis, there are a few other advantages: you can change out tags as easy as changing rings, for one. You can also easily loan your ring to someone just as you might give them keys to your door.
The ring is something close to two rings connected by slender pillars. Two of the three pillars are metal, but the third is the RFID tag. We wondered whether the tag and the pillars could take some sort of enamel that would conceal its look but not interfere with operation.
[Becky] is quite the artisan and even has a free online jewelry class over on Instructables. We were also impressed with her compact and tidy workspace that you can see in the video below.
This isn’t the first RFID ring we’ve seen, but it is a nice looking one. On the other hand, you can also sacrifice a credit card, but that has its own problems.

Athletes have a long history of using whatever they can find to enhance their performance or improve their training. While fitness tracker watches are nothing new, swimmers have used them to track their split times, distance, and other parameters. The problem with fitness trackers though is that you have to look at a watch. FORM has swim goggles that promise to address this, their smart goggles present the swimmer with a heads-up display of metrics. You can see a slick video about them below.
The screen is only on one eye, although you can switch it from left to right. The device has an inertial navigation system and is — of course — waterproof. It supposedly can withstand depths up to 32 feet and lasts 16 hours on a charge. It can use Bluetooth to send your data to your phone in addition to the display.
All this comes at a price, the goggles cost about $200. These aren’t the goggles from the dollar store, but even a nice pair of Speedo goggles might run $30 tops.
The device reportedly tracks split time, interval time, rest time, total time, stroke rate and count, distance per stroke, pacing, distance, length count, and even calories burned.
This reminds us of Google Glass. Most similar displays we’ve seen however have been automotive.

Making your own clothing can be fun, but it’s even better if you can throw some LEDs into the mix and give a new meaning to the term “glow up”. [arturo182] did just that with this custom rocket jacket for CCCamp2019.
We’re getting kind of a stained-glass vibe here.
To create the jacket, a 3D printed frame was created in the shape of CCCamp’s rocket logo. This was then filled with hot glue to act as a diffuser, and fitted with WS2818B LEDs. A Digispark is used as the microcontroller, with its compactness serving well for the wearable application. The assembly is then sewn into the back of a hoodie, with cardboard used on the inside as a backer to help keep things flat and support the weight of the hardware.
Hot glue works great as a diffuser in this application, and animation is easy thanks to the addressable LEDs used in the construction. It’s a great way to get a neon-like look, and we fully expect to see more of these glowy wearables in future!

Digital watches are a pretty neat idea, and are a great way to experiment with designing and building low-power circuits. That’s what [Eric Min] did with this neat smart watch build. It’s based around an nRF52832 SoC that does all of the heavy lifting, including connecting to a smartphone to get the time when the battery is replaced. It also has a decent quantity of blinky LEDs, which is important on any project of this type.
[Eric] freely admits that there are still some issues to overcome in his prototype. For one, the display tends to dim in use, probably because the 3V Lithium coin cell actually ends up delivering a bit less than that as it discharges, and the display is designed to work on a minimum of 3V. For the next version, he is thinking about using a 3.7V Lithium Polymer cell and a 3.3V regulator, which should be able to drive the display a little easier and keep it nice and bright. Or perhaps switch over to a nice OLED or eInk display.
Perhaps our favorite feature of the design from this 17-year old is the call-out on the back of the PCB: “I love you Mom and Dad”. Aww. I’ll bet your Apple Watch doesn’t have that, does it?

Jewelry making offers many opportunities for the electronics tinkerer, and on these pages we’ve seen some eye-catching creations using LEDs to great effect. They all have the same limitation though, it’s difficult to power something that tiny without a cumbersome battery. In seeking to solve that problem there have been a variety of inventive solutions tried, but they haven’t matched the approach of [Lloyd Konneker] who has turned the whole premise of most electronic jewelry on its head.
Instead of LEDs, the party trick of his earring is an electric motor that makes it spin, and instead of giving out light it takes it in as solar power. The motor is a pager alert device, the solar cells are repurposed photodiodes, and the power is stored in a capacitor until there is enough to drive the motor, at which point a MOSFET is triggered to do the work. It’s all made possible by a Texas Instruments TPS3839 supply voltage supervisor chip, and it works well enough to turn from time to time in bright sunlight. The prototype uses a conventional PCB, but a better version is in the works with a flexible board.
His write-up should be of interest to anyone with a need to learn about micropower circuits, as it goes into significant detail on their tuning and operation. Last year’s Hackaday Prize had an entire section devoted to energy harvesting which is well worth searching the site for, a typical example was this solar powered microcontroller board.

Despite the incredible advancements in special effects technology since the film’s release, the dinosaurs in 1993’s Jurassic Park still look just as terrifying today as they did nearly 30 years ago. This has largely been attributed to the fact that the filmmakers wisely decided to use physical models in many of the close-up shots, allowing them to capture the nuances of movement which really helps sell the idea you’re looking at living creatures.
[Esmée Kramer] puts that same principle to work in her incredible articulated dinosaur costume, and by the looks of it, Steven Spielberg could have saved some money if he had his special effects team get their supplies at the Home Depot. Built out of PVC pipes and sheets of foam, her skeletal raptor moves with an unnerving level of realism. In fact, we’re almost relieved to hear she doesn’t currently have plans on skinning the creature; some things are better left to the imagination.
In her write-up on LinkedIn (apparently that’s a thing), [Esmée] explains some of the construction tricks she used to help bring her dinosaur to life, such as heating the pipes and folding them to create rotatable joints. Everything is controlled by way of thin ropes, with all the articulation points of the head mirrored on the “steering wheel” in front of her.
Now to be fair, it takes more than a bundle of PVC pipes to create a convincing dinosaur. Obviously a large part of why this project works so well is the artistry that [Esmée] demonstrates at the controls of her creation. Judging by her performance in the video after the break, we’re going to assume she’s spent a not inconsiderable amount of time stomping around the neighborhood in this contraption to perfect her moves.
In the past we’ve seen the Raspberry Pi used to upgrade life-sized animatronic dinosaurs, but even with the added processing power, those dinos don’t hold a candle to the smooth and organic motion that [Esmée] has achieved here. Just goes to show that sometimes low-tech methods can outperform the latest technological wizardry.

These days, if you want a smart watch, you’re spoiled for choice. The major smartphone players all have devices on the market, and there’s plenty of third party manufacturers vying for your dollar, too. You might think it’s impossible achieve the same finish with a 3D printer and a reflow oven, but you’re wrong. [Samson March] didn’t quite fancy something off the shelf, though, and instead build an amazing smartwatch of his own.
The beautiful case is printed in a woodfilled PLA — consisting of 70% plastic and 30% sawdust. This allows it to be sanded and stained for an attractive final product. Printing artifacts actually add to the look here, creating somewhat of a woodgrain effect. There’s a round LCD for a more classical watch look, which displays various graphics and even contact photos for incoming messages. Like most smartwatches on the market, it uses Bluetooth Low Energy for communication, and has a rechargeable lithium battery inside. Estimated battery life is approximately one week, depending on the frequency of use, and the recharging base he fabricated is as beautiful as the watch itself.
It’s a tidy build that shows off [Samson]’s design skills, and files are available on GitHub if you’d like to make your own. Laying out the full design in Fusion 360 prior to the build enabled the watch to be optimized for size constraints, creating an attractive and comfortable piece. With that said, if you’re a fan of a more hardcore electronic aesthetic, perhaps something 8-bit might be more your speed.

Pivots for e-textiles can seem like a trivial problem. After all, wires and fabrics bend and flex just fine. However, things that are worn on a body can have trickier needs. Snap connectors are the usual way to get both an electrical connection and a pivot point, but they provide only a single conductor. When [KOBAKANT] had a need for a pivoting connection with three electrical conductors, they came up with a design that did exactly that by using a flexible circuit board integrated to a single button snap.
This interesting design is part of a solution to a specific …read more

The simplest answer to a problem is not necessarily always the best answer.

Part of what makes flamethrowers fun is their inherent danger. This is what makes a lot of things fun, though, from snowboarding to skydiving to motorcycle riding.
