This Animatronic Horus Guard Mask Is So Good, Even Anubis Would Be Fooled


[Jerome Kelty] is a big fan of the movie Stargate, and when he saw it for the first time, he wanted one of the awesome helmets worn by the Horus Guards. This isn’t the kind of thing you would normally find at your local costume shop, so he knew that he would have to build one of his own. After rejecting multiple designs over the years, he finally came up with a solution that he thought would work well.

His Horus Guard helmet was constructed primarily out of cardstock, papier-mâché, spray foam, and spackle. Don’t let that list of materials give you the wrong idea about this helmet however – it looks absolutely amazing!

Not only does it look good, but it moves just like the guard’s helmets in the movie too. To control the helmet’s movements [Jerome] used an Arduino animatronics setup he designed, which we’ve seen before in his slick Predator build from last year. The Arduino controls a set of 5 servos, which are tasked with turning the helmet’s head and actuating the fans mounted on either side.

Stick around to see a short video of the mask in action, and if you’re thinking of building one yourself, be sure to check out his writeup for a very thorough BoM.

Kitchen Hacks: An Android Bartender

[Nick] just finished up bis barbot build that is named after our favorite bartender. It’s an impressively capable even if it was done on the cheap.

The user chooses a libation for iZac to make via an Android tablet. This drink is interpreted by an Android ADK to have the mechanics of the robot swing into action and start making a drink.

The part of the build that moves the fluid was inspired by the Evil Mad Scientist Labs’ Drink Making Unit 2.0. Instead of pumps pulling the liquid through tubing, [Nick] attached an aquarium air pump to an Erlenmeyer flask. A siphon tube draws liquid out of the flask because of the difference in air pressure. The liquid is controlled by a few laser cut pinch valves that he designed.

Once a user selects a cocktail, the robot swings into action and dispenses liquid into a glass sitting on a load cell. Since the glass is being weighed at all times, iZac knows exactly how much alcohol (and in what proportion) is in the cocktail. [Nick] tested out iZac at the Sydney Hackerspace with soda water and flavoring. iZac proved very popular and we’re wondering if we could build something like this in a liquor cabinet.
