Procrastinators Rejoice! 2023 Supercon Call For Participation Extended

July 25, 2023 by Elliot Williams 4 Comments

When we closed the official Call for Participation for both workshops and talks last week, a good handful of folks wrote to us and asked if they could slip their presentation application in after the deadline. Who are we to say “no” to potential presenters? We want to see all the ideas!

We’re officially extending the Call for Speakers and the Call for Workshops for another week. Get your outline in before Aug. 1st at 9:00 AM PDT, and it’ll be in the selection for Supercon. (And no, we’re not going to extend it twice!)

The Hackaday Superconference is really and truly our favorite event of the year. It’s small, but not too small. The ideas everyone brings with them, however, are big. It’s like the absolute best of Hackaday live and in person. If you’re looking for a place to give a technical talk, or just to regale us all with the trials and triumphs of hacking, you won’t find a more receptive audience anywhere. Plus, presenters get in free.

Behind the scenes, we’re still working on the badge, but we’ve got many of the details fully hammered down. Expect tickets to go on sale in the second week of August – early bird tickets sell out fast. Keep your eyes on Hackaday for the announcement post when it goes live.

We know that November seems a long way out, but we’re looking forward to seeing you all already. Hooray for Supercon!

Supercon 2022: Joe Grand And The Thinnest Boombox

July 10, 2023 by Maya Posch 4 Comments

Boomboxes are one of those status symbols that define the 1980s and part of the 1990s, being both a miracle of integration and the best way to share your love of music with as many people as possible. Naturally, this led Joe Grand to figure that it would make it a perfect subject for a modern take on such an iconic device. The primary inspiration for this came from a piezo speaker developed by TDK called the ‘PiezoListen’. These are piezo devices that can be less than a millimeter thick, while still claiming to reproduce a broad range of audio frequencies.

Just having these speakers is only part of the solution, of course, which led Joe down the rabbithole of not only figuring out the components that should go into the system, but also how to get it all on a single PCB and see how far one can push different solder mask colors with an appropriately boombox-like design. At its core is a Raspberry Pi Zero 2 W that runs Mopidy, to provide music server functionality. Also added are some RGB lighting and touch controls.

Supercon 2022: Bradley Gawthrop Wants You To Join The PEV Revolution

July 3, 2023 by Navarre Bartz 70 Comments

During the 20th Century, much of the western world decided that motor vehicles were the only desirable form of transportation. We built our cities to accommodate cars through parking, stop lights, and any number of other infrastructure investments so that you could go get milk and bread in style. In the US, 50% of automobile trips are less than three miles and have only one occupant. [Bradley Gawthrop] asked if there might be a more efficient way to do all this? Enter the Personal Electric Vehicle (PEV).

What Are PEVs?

PEVs are a nascent part of the transportation mix that fall under the wider umbrella of “micromobility,” including scooters, bikes, skateboards, and the like. The key differentiator here is that they are at least partially electrically-driven. [Gawthrop] walks us through several of the different types during his Supercon 2022 talk, but since they are all small, electric powered devices for transporting one or two people, they can trace their lineage back to the infamous Segway Human Transporter.

Using an electric motor or two connected to a controller and batteries, the overall system complexity for any of these devices is quite low and ripe for the hacking. Given the right tools and safety precautions, anyone should be able to crack a PEV open and repair or tinker with it. As with many things in life, the real story is more complicated.

As [Gawthrop] notes, many a hacker has said, “I wish I’d been able to be involved in X before…” where X equals some technology like home automation and it’s before it got creepy or dystopian in some manner. He exhorts us that the time to be in on the ground floor with PEVs is now. Continue reading “Supercon 2022: Bradley Gawthrop Wants You To Join The PEV Revolution” →

Vintage Computer Festival Southwest: Bil And Al’s Excellent Adventure

June 30, 2023 by Al Williams 12 Comments

There was a time when seeing an actual computer was a big deal. They were in air-conditioned rooms with raised floors and locked doors. Even at a university, you were likely only to get access to a keypunch machine or a terminal. Then small computers came out, but computer stores were few and far between. Now you can go to any local store that sells electronics and put your hands on hardware that would have been black magic in those days. But the computers back then were also much easier to understand completely. Look at your main computer today. Do you know all the assembly language instructions for it? Can you access the GPU and the MMU? Could you build your own memory for it? Sure, you don’t have to do those things, but it was fun knowing that you could. That seemed to be the overwhelming sentiment among the attendees we spoke to at the Vintage Computer Festival last weekend: We like computers that we can completely understand and troubleshoot.

If you weren’t one of the 900 or so attendees, we can help. Check out our video summary, dive into even more interviews with Bil Herd and guests on our YouTube channel, or just keep reading. The festival happens at several locations throughout the year, but this was the first time one has been in the Southwest for about ten years!

Supercon 2022: [Liz McFarland] Builds Golden Wings, Shows You How

June 13, 2023 by Arya Voronova 7 Comments

Are you, by any chance, wondering about giving yourself wings? You should listen to [Liz McFarland] sharing her experience building a Wonder Woman suit, and not just any – the Golden Eagle suit from Wonder Woman 1984, adorned with a giant pair of wings. If a suit like that is in your plans, you’ll be warmly welcomed at a cosplay convention – and [Liz] had her sights on the San Diego Comic Con. With an ambitious goal of participating in the Comic Con’s cosplay contest, the suit had to be impressive – and impressive, it indeed was, not just for its looks, but for its mechanics too.

[Liz] tells us everything – from producing the wings and painting them, to keeping them attached to the body while distributing the weight, and of course, things like on-venue nuances and safety with regards to other participants. The dark side of cosplay building reality isn’t hidden either – talking, of course, about the art of staying within a reasonably tight budget. This build takes advantage of a hackerspace that [Liz] is an active member in – the [Crash Space] in LA. Everything is in – lasercutting, 3D printing, and even custom jigs for bending wing-structual PVC pipes play a role.

It would have been a travesty to not have the wings move at will, of course, and [Liz] had all the skills you could want for making the wings complete. She went for two linear actuators, walking us through the mechanical calculations and considerations required to have everything fit together. It’s not easy to build a set of wings on its own, let alone one that moves and doesn’t crumble as you use it – if you have already attempted bringing mechanical creations like this into life, you can see the value in what [Liz] shares with us, and if you haven’t yet delved into it, this video will help you avoid quite a few pitfalls while setting an example you can absolutely reach.

The suit was a resounding success at the con, and got [Liz] some well-earned awards – today, the suit’s story is here for the hackers’ world. Now, your cosplay aspirations have an inspiring real-life journey to borrow from, and we thank [Liz] for sharing it with us.

Supercon 2022: [Jorvon Moss] Gives His Robots A Soul

May 30, 2023 by Arya Voronova 6 Comments

How do you approach your robot designs? Maybe, you do it from a ‘oh, I have these cool parts’ position, or from a ‘I want to make a platform on wheels for my experiments’ perspective. In that case, consider that there’s a different side to robot building – one where you account for your robot’s influence on what other people around feel about them, and can get your creations the attention they deserve. [Jorvon ‘Odd-Jayy’ Moss]’s robots are catchy in a way that many robot designs aren’t, and they routinely go viral online. What are his secrets to success? A combination of an art background, a Bachelor of Fine Arts in illustration, and a trove of self-taught electronics skills helped him develop a standout approach to robot building.

Now, [Jorvon] has quite a few successful robot projects under his belt, and at Supercon 2022, he talks about how our robots’ looks and behaviour shapes their perception. How do your own robots look to others, and what feelings do they evoke? With [Jorvon], you will go through fundamentals of what makes a robot look lively, remarkable, catchy or creepy, and it’s his unique backgrounds that let him give you a few guidelines on what you should and should not do when building a certain kind of robot.

You’ll do good watching this video – it’s short and sweet, and shows you a different side to building robots of your dreams; plus, the robot riding around on the stage definitely makes this presentation one of a kind. No matter your robot’s technical complexity, it’s significant that it can make people go ‘wow’ when they see it. Not all robots are there to single-mindedly perform a simple task, after all – some are meant to travel around the world.

Supercon 2022: Nick Poole Makes A Jolly Wrencher Tube

May 23, 2023 by Chris Lott 5 Comments

[Nick Poole] shared his circuitous journey into the obscure world of homemade vacuum tubes on the Supercon 2022 stage. It began innocently enough when he saw [Usagi Electric]’s single bit computer vacuum tube computer, which uses dozens of vacuum tubes. He got to wondering, could you make vacuum-tube-like devices containing multiple elements? There are some examples, like the 256-bit memory Selectron tube from the 1950’s, but nothing general purpose like a 555 timer or quad NAND gate packages. Unencumbered by a deep understanding of how vacuum tubes work, [Nick] proceeds to fill this void by imagining Integrated Thermionic, a fictitious company that exists in an alternate history where transistors were not invented and the vacuum tube reigns supreme. He also showcases a variety of innovative products that Integrated Thermionics manufactured over the decades, including surface mount tubes.
