Building A Gimballed Motorcycle Helmet Camera From Scratch

[Nixie Guy] has hit all of important design elements in a single motorcycle helmet-cam project which packs in so much that the build log spans three posts. These cameras need to stand up to the elements and also to being pelted by insects at 80 MPH. They need to attach securely to the helmet without interfering with vision or movement of the head. And you should be able to adjust where they are pointing. The balance of features and cost available in consumer cameras make this list hard to satisfy — but with skills like these the bootstrapped camera came out great!

Where can you get a small, high quality camera? The drone industry has been iterating on this problem for a decade now and that’s where the guts of this creation come from. That produced an interesting issue, the board of the CADDX Turtle V2 camera gets really hot when in use and needs to have air flowing over it. So he threw a custom-milled heat sink into the side of the SLA resin printed housing to keep things somewhat cool.

Since the mill was already warmed up, why not do some mold making? Having already been working on a project to use a casting process for soft PCB membranes, this was the perfect technique to keep the buttons and the SD card slots weather tight on the helmet cam. A little pouch battery inside provides power, and the charging port on the back is a nice little magnet job.

Everything came together incredibly well. [Nixie Guy] does lament the color of the resin case, but that could be easily fixed by reprinting with colored resin.

While you’re bolting stuff onto your helmet, maybe some excessive bling is in order?

Replica Marshmello Helmet Is A Tidy Halloween Build

As the saying goes – you don’t need a stylized, bedazzled helmet to have a successful career in EDM, but it helps. Marshmello is the latest in a long line of musicians to sport bespoke headgear, and [MikeTheSuperDad] undertook the construction of a replica for Halloween.

The build starts with a piece of concrete form tube as the base of the helmet. This is combined with 3D printed components to create a grid in which to place WS2812B LED strings. These are controlled by an Arduino Pro Mini, which is responsible for handling the animations. Further 3D printed parts are used as templates to cut out the characteristic eyes and mouth, as well as to cover the top. Plastic sheeting is then used over the top of everything to diffuse the LEDs and provide the final look, with black mesh behind the eyes and mouth making them properly stand out.

Marshmello should be lauded for creating a helmet with a distinctive visual style, while remaining easy to replicate, unlike popular Daft Punk builds of years past. Building a replica could serve as good practice before starting out on your own unique build. Video after the break.

Smart Bike Helmet Is Wireless

If you ride a bike, you probably share the road with a lot of cars. Unfortunately, they don’t always share the road very well with you. [Mech Tools] took a helmet, a few Arduinos, and some wireless transceivers and made headgear that shows when you stop and also shows turn signals. We were a little surprised, though, that the bike in question looks like a motorcycle. In most countries, motorcycle helmets meet strict safety standards and modifying them is probably not a good idea. However, it wasn’t exactly clear how the extra gear attached to the helmet, so it is hard to say if the project is very practical or not.

In particular, it looks as though the first version had the electronics just stuck to the outside of the helmet. The final one had things mounted internally and almost certainly had cuts or holes made for the lights. We aren’t sure which of those would be more likely to be a problem in the case of an accident.

Hackaday Superconference: Estefannie’s Daft Punk Helmet

There’s no single formula for success, but if we’ve learned anything over the years of covering cons, contests, and hackathons, it’s that, just like in geology, pressure can create diamonds. Give yourself an impossible deadline with high stakes, and chances are good that something interesting will result. That’s what Estefannie from the YouTube channel “Estefannie Explains It All” did when Bay Area Maker Faire was rolling around last year, and she stopped by the 2018 Hackaday Superconference to talk about the interactive Daft Punk helmet that came out of it.

It’s a rapid-fire tour of Estefannie’s remarkably polished replica of the helmet worn by Guy-Manuel de Homem-Christo, one half of the French electronic music duo Daft Punk. Her quick talk, video of which is below, gives an overview of its features, but we miss the interesting backstory. For that, the second video serves as a kickoff to a whirlwind month of hacking that literally started from nothing.

You’ll Learn it Along the Way

Before deciding to make the helmet, Estefannie had zero experience in the usual tools of the trade. With only 28 days to complete everything, she had to: convert her living room into a workshop; learn how to 3D print; print 58 separate helmet parts, including a mold for thermoforming the visor; teach herself how to thermoform after building the tools to do so; assemble and finish all the parts; and finally, install the electronics that are the hallmark of Daft Punk’s headgear.

The three videos in her series are worth watching to see what she put herself through. Estefannie’s learning curve was considerable, and there were times when nothing seemed to work. The thermoforming was particularly troublesome — first too much heat, then not enough, then not enough vacuum (pretty common hurdles from other thermoforming projects we’ve seen). But the finished visor was nearly perfect, even if it took two attempts to tint.

We have to say that at first, some of her wounds seemed self-inflicted, especially seeing the amount of work she put into the helmet’s finish. But she wanted it to be perfect, and the extra care in filling, sanding, priming, and painting the printed parts really paid off in the end. It was down to the wire when BAMF rolled around, with last minute assembly left to the morning of the Faire in the hotel room, but that always seems to be the way with these kinds of projects.

In the end, the helmet came out great, and we’re glad the run-up to the Superconference wasn’t nearly as stressful for Estefannie — or so we assume. And now that she has all these great new skills and tools, we’re looking forward to her next build.

Gaze Upon This Daft Punk Helmet’s Rows Of Utterly Perfect Hand-Soldered LEDs

The iconic robot helmets of Daft Punk feature prominently as challenging DIY hardware projects in their own right, and the results never disappoint. But [Nathaniel Stepp]’s photo gallery of his own version really sets the bar in both quality and attention to detail. The helmet uses a Teensy 3.2 as the main processor, and the visor consists of 328 hand soldered through-hole APA106 addressable RGB LEDs. A laser cut panel serves as the frame for the LEDs, and it was heat-formed to curve around the helmet and mate into the surrounding frame. Each LED is meticulously hand-soldered, complete with its own surface mount decoupling cap; there’s no wasted space or excess wire anywhere to be seen. It looks as if a small 3D printed jig was used to align and solder the LEDs one or two columns at a time, which were then transferred to the visor for final connections with the power bus and its neighboring LEDs.

After the whole array was assembled and working, the back of each LED appears to have then been carefully coated in what looks like Plasti-Dip in order to block light, probably to minimize the blinding of the wearer. A small amount of space between each LED allows the eyeballs inside the helmet to see past the light show in the visor.

The perfectly done array of LEDs in the visor is just one of the design elements showing the incredible workmanship and detail in [Nathaniel]’s helmet. His website promises more build details are coming, but in the meantime you can drink in the details shown in the aforementioned photo gallery.

With Halloween approaching, you might be interested in rolling your own Daft Punk inspired helmet. Not ready to do everything from scratch? No problem, because it’s never been easier to make your own with the help of a 3D printer and some LED strips.

Cheap And Easy Helmet Lights For The Kids

Bikes are a great way to get around and get exercise at the same time, and are widely popular with human children due to the fact that they’re generally not allowed to drive. However, riding on or next to the road can be dangerous, particularly at night, when even adults on bikes are hard to see. It’s far worse for the youngest children, who can be incredibly small and difficult to spot. [Patrick]’s children enjoy riding, but it can get a little sketchy at night, so he developed a solution.

The project relies on cheap, commonly available LED strip lights. Rather than any fancy addressable strips, these are just simple strings of LEDs with current limiting resistors already fitted in a convenient, adhesive backed format. This makes the job as easy as peeling off the backing tape, sticking the strips to the helmet, and providing a power source. In clsasic entry-level hack style, everything’s running off a single 9V battery. Is it as versatile as a rechargable lithium pack with integrated controller? No, but it’s a swift way to get a project off the ground.

The trick here isn’t so much the hardware side of things – there’s nothing fancy about a battery and some LEDs. The key here is that [Patrick] identified that his children are small and difficult to see, thus it made sense to fit helmet lights rather then more typical bike lights to make them more visible to surrounding traffic.

For something at the other end of the spectrum, check out this amazingly professional LED bike light.

Stormtrooper Voice Changer Helmet Uses Teensy To Mangle Audio

Halloween has come and gone, but this DIY voice changing Star Wars Stormtrooper helmet tutorial by [Shawn Hymel] is worth a look for a number of reasons. Not only is the whole thing completely self-contained, but the voice changing is done in software thanks to the Teensy’s powerful audio filtering abilities. In addition, the Teensy also takes care of adding the iconic Stormtrooper clicks, pops, and static bursts around the voice-altered speech. Check out the video below to hear it in action.

Besides a microphone and speakers, there’s a Teensy 3.2, a low-cost add-on board for the Teensy that includes a small audio amp, a power supply… and that’s about it. There isn’t a separate WAV board or hacked MP3 player in sight.
