Four Of Our Favorite Hardware Talks

The Hackaday SuperConference is the greatest gathering of hardware hackers on the planet. Last year at the SuperCon, we saw talks on building systems from scratch, creating new and interesting uses for technology, and bringing those electronic bits to market. What are we talking about? Here are four of the best talks from last year’s Hackaday SuperConference:

Denver Mini Maker Faire Roundup

I had a great time at Denver’s 3rd annual Mini Maker Faire, which was held inside the Denver Museum of Nature and Science. The official theme this year was “Building the Future” and looking back, I can tell you that they pulled the theme off well. There was a strong turnout in two categories that are crucial to building the future: the growth that comes from education at all ages and the physical places where learning becomes immersive.

The Really Fun Stuff

poison arrow[Casey] from Caustic Creations were showing off Poison Arrow just in time for season 2 of the BattleBots reboot. Poison Arrow is 250-lb. drum spinner that destroys things at 9,000 RPM. Here’s a nice introductory video shot by their sponsor, Arrow Electronics. [Casey] told me that Poison Arrow will be on the June 30th episode, so set your DVR.

Who knew that Colorado had so many maker- and hackerspaces? Colorado Makerhub, that’s who. They provide a portal to everything maker-related in Colorado, and they were in attendance along with most of the ‘spaces within a 50-mile radius of the city. Denver’s own Denhac brought a huge multiplayer rig that they had built for Comic Con last year. It runs Artemis, a spaceship bridge simulator game that divides up the tasks necessary for successful intergalactic travel. Here’s a video of Denhac member [Radio Shack] describing the game and giving a tour of one of the consoles. The group landed a space in one of the darker areas of the museum, which made the blinkenlights irresistible, especially to boys of a certain age range.

Bootstrapped Tools, Live Stopped Motion, and a Dekatron Computer

Dallas Texas played host to an epic Hackaday meetup last weekend. The Dallas Makerspace was kind enough to open their doors, and we sure used them. Attendance was over capacity, with a line all night to screen-print your own T-shirt, a set of lightning talks that lasted nearly two hours, and plenty of hardware show-and-tell.

We’ll start off with three of the most impressive builds displayed. First is a set of simple designs that can be used to make tools in parts of the world where even a hammer is a luxury. Then it’s on to a clever entertainment device that uses discrete stopped-motion figurines to make live animations. We’ll take a look at the Witch-E project which is building a replica of the famous Dekatron-based computer. And finish up with the surprise hit of the meetup.

Clocks for Social Good

Over the past five days we’ve been challenging the Hackaday community to build a clock and show it off. This is to raise awareness for electronics design in everyday life and hopefully you found a non-hacker to join you on the project. The point is that our society — which has pretty much universally accepted everyday carry of complex electronics — has no idea what goes into electronic design. How are we supposed to get kids excited about engineering if they are never able to pull back that curtain and see it in action?

Build something simple that can be understood by everyone, and show it off in a way that invites the uninitiated to get excited. What’s simpler than a clock? I think of it as the impetus behind technology. Marking the passage of time goes back to our roots as primitive humans following migratory herds, and betting on the changing seasons for crop growth. Our modern lives are governed by time more than ever. These Clocks for Social Good prove that anyone can understand how this technology works. And everyone who wants to learn to build their own electronic gadget can discover how to do so at low-cost and with reasonable effort. This is how we grow the next generation of engineers, so let’s take a look at what we all came up with over the weekend.

All the Unofficial Electronic Badges of DEF CON

2015 was the year of the unofficial hardware badge at DEF CON 23. There were a ton of different hardware badges designed for the love of custom electronics and I tried to catch up with the designer of each different badge. Here is the collection of images, video demos, and build details for each one I saw this weekend.

Whiskey Pirates

[TrueControl] did a great job with his badge design this year for the Whiskey Pirate Crew. This is a great update from the badge he designed last year, keeping the skull and bones outline. It uses a PSOC4 chip to control a ton of LEDs. The eyes are RGB pixels which are each on their own PCB that is soldered onto the back of the badge, with openings for the LED to show through. Two AA batteries power the board which has a surface-mount LED matrix. The user controls are all capacitive touch. There is a spinner around one eye, and pads for select and back. The NRF24L01 radio operates at 2.4GHz. This badge is slave to commands from last year’s badge. When the two are in the same area the 2015 badges will scroll the nickname of the 2014 badge it “sees”. The piezo element also chirps many different sounds based on the interactions with different badges.

[True] makes design an art form. The matte black solder mask looks fantastic, and he took great care in use of font, size, alignment, and things like letting copper show through for a really stunning piece of hardware art.

Keep reading for ten more great badges seen over the weekend.

Maglev, Submersibles, and More at Maker Faire Detroit

This past weekend the Maker Faire returned to the motor city. While it seemed a bit smaller than previous years, the event still brought in a ton of awesome makers from the metro Detroit area and beyond.

Although we don’t feature too many woodworking projects, there were quite a few woodworkers at the Faire with projects ranging from custom longboards pressed with a home built iron mold to DIY kayaks with elaborate wooden skeletons built by a local group of Michigan kayak builders. The kayaks were quite impressive: hand sewn nylon panels are wrapped around custom frames made from steamed white oak. It’s great to speak with the makers about the specialized skills needed for kayak building.
