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.

Supercon 2022: Andy Geppert Is Bringing Core Memory Back

May 18, 2023 by Tom Nardi 22 Comments

Many Hackaday readers will be familiar with the term “core memory”, likely thanks to its close association with the Apollo Guidance Computer. But knowing that the technology existed at one point and actually understanding how it worked is another thing entirely. It’s a bit like electronic equivalent to the butter churn — you’ve heard of it, you could probably even identify an image of one — but should somebody hand you one and ask you to operate it, the result probably won’t be too appetizing.

That’s where Andy Geppert comes in. He’s turned his own personal interest into magnetic core memory into a quest to introduce this fascinating technology to a whole new generation thanks to some modern enhancements through his Core64 project. By mating the antiquated storage technology with a modern microcontroller and LEDs, it’s transformed into an interactive visual experience. Against all odds, he’s managed to turned a technology that helped put boots on the Moon half a century ago into a gadget that fascinates both young and old.

In this talk at the 2022 Hackaday Supercon, Andy first talks the audience through the basics of magnetic core memory as it was originally implemented. From there, he explains the chain of events that lead to the development of the Core64 project, and talks a bit about where he hopes it can go in the future.

VCF East 2023: Retro Luminaries Take The Stage

April 23, 2023 by Bil Herd 4 Comments

Our friend [Fran Blanche] recently recorded what it was like to participate in an energetic round table at the recently held Vintage Computer Festival (VCF) East. Fran joined well known personalities [Jeri Ellsworth], [Adrian Black] of Adrian’s Digital Basement, and Usagi Electric creator [Dave Lovett] with yours truly moderating.

The table-less roundtable discussed the pros and cons of streaming about retro and tech, and what its like to hang yourself out there in video format. Goals and motives differed widely from speaker to speaker and there was some good-natured ribbing about who makes money vs. who simply gets away with spending less.

Most of all fun was had by the speakers as they interacted with each other, and with the audience — and that comfort came across to the standing room only crowd of avid retro-enthusiasts who only told us good things about what they saw and heard that night.

One thing we did note was that every speaker actually knew what microphones were and how to use them.

Want to learn more about the 2023 Vintage Computer Festival East? You can start by checking out our previous coverage, and don’t miss the first in a series of fascinating interviews recorded by the Hackaday crew as they explored this phenomenal retrocomputing event.

Vintage Computer Festival East Was A Retro Madhouse

April 19, 2023 by Tom Nardi 36 Comments

The Vintage Computer Festival East took place last weekend at the InfoAge Science and History Museum in New Jersey, and by any metric you care to use, it was a phenomenal success. Everyone you spoke with, from the the exhibitors and attendees, to the veteran volunteers who put this incredible show together, all said the same thing: they’d never seen a turnout like this before.

Of course, such success is not without cost. The exhibit rooms were so packed that moving through them was a challenge, the line to get food or browse the consignment area occasionally stretched outside the building, and at one point the event’s electronic payment system buckled under the pressure.

Yet even the folks who waited the better part of an hour to rummage through boxes of dusty treasures, only to find themselves left standing with armfuls of heavy gear they couldn’t pay for until the technical issues were resolved couldn’t really complain. I should know, I was one of them. It would be like going to a concert and getting upset that the music was too loud — the event was advertised as a festival, and that’s exactly what it was.

No matter where you went, you’d find throngs of excited people who were eager to chat about the golden age of computing. So even if you were stuck in a long line, or had to step outside of the exhibit area to get some fresh air, you were always in excellent company. Seeing such a large and diverse number of people come out for what’s ultimately a niche event was exceptionally gratifying. At the end of the day, if the price we have to pay for this kind of community response is a few long lines and tight squeezes, it’s well worth it.

Each time I cover an event like this for Hackaday, I do so with the caveat that there’s really no substitute for being there in person. No matter how many articles you read and YouTube recaps you watch, you’ll never be able to see all the things you would have had you been able to walk the show floor yourself. It’s a bit like exploring the Moon or Mars: remotely controlled robots are capable of capturing terabytes of data and beaming it back to Earth, but even still, there’s the potential to learn so much more by putting boots on the ground.

The same is true of VCF East 2023 — what I bring you here is just the tip of the iceberg in terms of what was on display at this year’s event. On the other hand, you have the advantage of being able to peruse these images without having to stand in line. Is it worth the trade? Only you can be the judge of that. But for my money, I’ll gladly get back in line when VCF East 2024 rolls around.

Vintage Computer Festival East Returns This Weekend

April 13, 2023 by Tom Nardi 11 Comments

Spring has sprung at the Jersey Shore, and for retrocomputer aficionados that can only mean one thing — the Vintage Computer Festival East is imminent. The East Coast’s premier event for classic computers and associated electronics kicks off tomorrow at the InfoAge Science and History Museum in Wall, NJ, and continues until Sunday. If you’re in the Northeast United States, and frankly, even if you aren’t, you’d be hard-pressed to find a better opportunity to experience the unique charms of early computer technology.

VCF East is three days of talks, workshops, and exhibits focusing on computers of a bygone area. For the uninitiated, that might seem like an odd thing to fixate on. But those who’ve visited a VCF event in the past know just how fascinating the technology of this era can be. You’ll see first-hand not only the unique machines that never quite caught on with the mainstream but the pioneering software and hardware engineering that laid the groundwork for our modern way of life. Plus, a little bit of everything in between. Just take a look at this year’s schedule; even the most experienced of graybeards would have a hard time walking away from VCF East without knowing a bit more than when they came in.

Part of what makes the Vintage Computer Festival so great is right in the name — it’s very literally a festival. This isn’t some sterile museum environment where you’re forced to look at a dusty piece of hardware through a half-inch of bulletproof glass. It’s a celebration, and everyone’s invited. Many of the exhibits will give you an opportunity to go hands-on with rare pieces of original hardware, and every presenter you talk to will be more than happy to explain what they’ve come to show off and answer any questions you might have.

In addition to the more educational aspects of VCF, there are also the vendor and consignment areas, which offer a myriad of opportunities to convert your money into devices that whir and blink. From classic gaming systems to unusual components that perhaps only a handful of people in the world could still identify at a glance, the only things you won’t find are the jacked-up prices and shipping costs you’d get from eBay.

Of course, the organizers realize that not everyone can get to the tropical paradise that is New Jersey in April. As such, VCF East will offer an online component that includes an official Discord server and three different live streams for the talks held on Friday, Saturday, and Sunday. That said, there won’t be any streaming video from the show floor itself, so unfortunately, you won’t be able to see any of the exhibits or workshops. That said, you can always count on there being several VCF wrap-up videos posted to YouTube by the usual retrocomputing suspects, to say nothing of the coverage you’ll be seeing on these pages.

Whether you’re there in person or experiencing it vicariously through the videos and articles posted by others, the Vintage Computer Festival East is a can’t-miss event for anyone who has a passion for computers and would like to learn more about how they became what they are today. Hackaday will be there — join us, won’t you?
