Glowing Eyes For Regular Guys

Cosplayers continually push the boundary of what’s possible in live costuming, often taking effects from the silver screen and creating them in real life. [KyleofAsgard] is no exception, bringing Thor’s glowing eyes to life in this impressive build.

The helmet is a 3D printed piece from Thingiverse, painted and distressed by hand.

The build relies on special contact lenses, which [Kyle] suggests are best sourced by searching for “electric blue contact lenses”. These glow in the presence of UV light, which here is provided by a strip of UV LEDs embedded into Thor’s helmet from the recent Marvel movies.

The concept is simple, but the attention to detail is what makes this project a winner. Not content with an earlier build that was a tangle of wires and uncomfortable to use, [KyleofAsgard] made some smart upgrades. The battery for the LEDs and all circuitry is built into the helmet, making it easy to take on and off on those long convention days. For a more impressive effect, a relay is used to turn the LEDs on by remote control with a 433MHz module. This allows [Kyle] or an assistant to trigger the effect covertly, adding plenty of drama when the eyes suddenly begin to shine. It’s all done with off-the-shelf parts that even a novice could put together.

Giving credit where it’s due, [Kyle] notes that his work was inspired by that of Instagram cosplayer [missxboof], who executed a similar concept earlier this year. It’s great to see the cosplay community coming together and sharing tips and techniques online. Of course, if your tastes are more Metroid than Marvel, you might prefer this arm cannon build.

Improve your vision with computer generated glasses

[Vitor Pamplona] sent in a project presented at this years SIGGRAPH. It’s a piece of hardware that corrects vision without the need for lenses. Yep. software-defined eyeglasses now exist, even if the project is a bit bulky for daily wear.

[Vitor] et al came up with two versions of hardware for this project. The first is a dual stack of high-resolution LCD displays, while the second revision is an LCD with a lenticular overlay. With this hardware, the team can change the focal plane of an entire image, or just subsets of an image allowing for customized vision correction for anyone with nearsightedness, farsightedness, astigmatism, presbyopia, and even cataracts.

With plenty of head-mounted augmented reality platforms coming down the pipe such as Google’s Project Glass and a few retina displays, we could see this type of software-defined vision correction being very useful for the 75% of adults who use some form of vision correction. It may just be a small step towards the creation of a real-life VISOR, but we glasses-wearing folk will take what we can get.

You can check out the .PDF of the paper here, or watch the video after the break.

Automated squinting instead of glasses, contacts, or lasik

[Lee] is nearsighted and has had it with contacts and glasses. When trying to figure out an alternative, he looked at the core of the problem. The eye is not shaped correctly and therefore cannot focus adequately. The solution is to change the shape of the lens. This is exactly what lasik (laser eye surgery) does, but instead of going under the incredibly bright knife [Lee] built some headgear that pulls on your face to reshape your eye.

The hardware is from an old portable CD player. The sled that moved the laser lens has been repurposed to pull a thread taped to the skin at the corner of his eye. He built a control system that lets him adjust the tension by moving his fingers. Basically when the skin is pulled tight it causes him to squint and possibly reshapes the cornea just a bit. We’re not sold on the idea, but we can’t poo-poo the experiment; who knows what discovery this could lead to? We’re just glad he didn’t use electrical impulses to hack his peepers.

You can find some test video embedded after the break.
