Here is a post from [John’s Projects]. For the insane, satirical, and incredible 2011 Omaha Groundhog Prom [John] and his buddy fabricated helmets reminiscent of our favorite robot rockers. [John] needed something harder, better, faster, stronger than the competition and wound up creating LED matrices that mount behind aerodynamic motorcycle helmet visors.
The helmets were constructed in about a weeks time and in a similar fashion to the real helmets. [John] sourced some cheap motorcycle headgear and mounted the LEDs, their driving transistors, and ballast resistors to a 1/32″ (flexible) plexiglass sheet that sits face to face with the wearer. [John] walks through the whole process starting with a half inch grid drawn onto a paper template. The template is cut from the plexi using tin snips, then LED holes are carefully drilled in the thin plastic using various bits up to 13/64″. The 90 some odd LEDs are, one more time, fitted then hot glued in place and soldered in vertical columns to simplify things and prevent any short circuit. An Arduino Pro (via common emitter 2n2222 on/off circuits) provides some digital love to the 18 LED columns and is connected to a Velleman Sound-to-light kit which modulates the brightness of the whole visor based on da funk. Two pots are also wired to provide sensitivity and pattern selection to the human after all.
We can’t imagine the technologic setup is fresh after being subjected to the steam machine, high life, and whatever else for too long. Oh yeah, Some brighter LEDs could give the helmets night vision and make the whole thing come alive with emotion. Something about us is burnin to know what powers the helmets. Nice work [John]!

[Dr. West] shared his Halloween costume with us; a Daft Punk inspired voice-changing helmet. He stared with a motorcycle helmet, cutting out a hole in the back for a sub-woofer speaker. Inside there’s an old computer mic and the amp circuitry for a portable stereo system. An Arduino is used to pick up the wearer’s voice from the microphone and perform the digital signal processing. Once the alterations have been made the signal is sent to an R-2R resistor ladder to perform the digital to analog conversion, and onto the amp for broadcast. Hear the result in the video after the break.
The rest of the helmet is window dressing. He found some kind of auto-body repair product called flex-edging to use as metallic hair. Those fins are accented with strings of red and blue LEDs. The faceplate finishes the look using speakers from the stereo system and a tinted visor.
He wan’t going for a replica, but we think his creation would be right at home with the look of the original.

This beautifully crafted Daft Punk table with iPod dock was built by [Dustin Evans]. The table itself was built with the help of a friend in one day with electronics added a bit later. It features an 8×8 grid of boxes with red LEDs mounted inside. The picture above is not quite the finished product, a diffuser will be added later to augment the scattering of light already provided by cutting the tip off of each LED. On the underside you’ll find a power supply and a set of speakers. The system is controlled by an Arduino which resides in the same drawer as the dock. See the final product in the clip after the break.

[Harrison Krix] finished his Daft Punk Helmet replica and posted about it this week. We took a look at his work back in October but he’s come a long way to pull off a legendary build. Take three minutes after the break and see 17 months worth of work. So many skills were pulled together to make this happen; sculpting, mold making, painting, electronic design, mechanical design, and bad-ass-ery. Crammed in along with your noggin are a bag-full of LED boards but the Arduino that controls it all resides outside, in a project box tethered to the helmet. This is a masterpiece of socially-unwearable geek fashion.

This looks like a home entertainment center of yore but something’s not quite right. Where is the turntable used to play the music? It turns out that this Danforth Standard Digitrola is digital and doesn’t rely upon wax for an input. [Jonathan Danforth] built it as a show piece and it exhibits fine craftsmanship. A sound driver uses the brass horn and the acoustical chamber to put out what sounds like a fine quality end product. Hear it playing some Daft Punk in the video after the break. The music comes from an MP3 board inside that has a 50W amplifier and reads the music from an SD card. The only control available to the listener is the brass knob which controls the volume.

[Andrew] built a light box for an exhibition last year that displayed different colors statically. After showing it off, it went unchanged but future improvements remained in the back of his mind. Recently, he pulled it out again and hacked together a controller to drive the colors individually.
He’s actually reusing some of the hardware he built for a different project. At its core is a PIC 16F628 that actuates the lights using relays. In this case, only four of the eight on the board are used to control red, white, blue, and green cold cathode tubes. The video after the break shows the device randomly rotating through different patterns. This is a nice start to making the piece more interactive and we can image adding web-controlled color changes, or perhaps some Daft Punk inspired functionality.

For all their varied and entertaining uses, circuits and code comprise only part of the complete hacking experience. To really put your project over the top, sooner or later you’ll want to possess some physical fabrication skills. Consider the works of [Ben Heckendorn]: He’s always done a fantastic job with the electronics, but it’s the fit and finish of the enclosures that make him a legend.
“Fabrication” usually conjures images of shop tools — saws and sanders and drills — all tremendously useful skills worth learning, and easily within reach of most home shops or garages. Recently, the techniques of mold making and casting have seen something of a DIY renaissance. Mold making is nothing new, the basic concepts go back millennia, but in just the past few years the materials for extremely high-quality molds have become safer, simpler to use, and easier to acquire.
This being Halloween month, what better example of the medium than this impeccable replica helmet styled after half of the musical duo Daft Punk (a recurring theme among Hack a Day contributors), created by prop maker [Harrison Krix]. After sculpting an original master part (from common hardware store and art store materials, we might add), a one-piece flexible mold is built up from silicone, which captures every minute detail, and later the helmet form is cast from a thin layer of resin. The visor is vacuum formed. A follow-up with the internal electronics build is yet to be posted, but even at this stage the shell alone is so refined it looks straight off a showroom floor. If mold making can do this for someone’s noggin, imagine what it can do for your next creative hardware project. Smooth-On, a major supplier of these materials, has a free PDF introduction and a set of tutorials on their web site.
