Outline 2022: Everyone Should Go To A Demo Party

June 6, 2022 by Jenny List 9 Comments

The community of Hackaday readers is diverse and talented, and supplies us with plenty of motivation, feedback, knowledge, and of course cool stuff to show you. There are many interest streams within it, but it’s safe to say that we’re more directed towards the hardware scene here. One of those parallel streams which has much overlap is the demoscene, that area in which programming, art, and music come together and push computer hardware to the limit of its abilities in pursuit of the most eye-catching works. I took a road trip with a friend to Outline, a small demo party held on a farm in the eastern Netherlands, to take a look at the world of demos up-close as a hardware-focused outsider.

Like A Hacker Camp, But The Music’s Better

If I wanted to sum up the flavour of Outline, I’d describe it as very similar to a small hacker camp, but with better music and partying. The hackerspaces are replaced by demo groups and awesome graphics take the place of robots and electronics, but the vibe of people with a passionate interest in the low-level understanding of technology is exactly the same. Even some of the same faces make an appearance. On the benches sit modern high-spec PCs alongside classic consoles and microcomputers, on the projector screen are live coding shaders or some of the most recognisable demos past and present, and in the air is an eclectic mix of live-DJ EDM and chiptunes.

As an outsider at a first demoscene event it’s difficult to appreciate the work from a comparative perspective, while like most of us I’m familiar with quite a few demos that have become popular I’m not well-equipped enough to talk about the code and techniques behind them But I can run through the various sections of the competition, and since everything is online I can link to a few of them. The competition is split up into several sections, which are loosely for all-out technology-no-object demos, space-limited 256 byte and 128 byte demos, and old-school demos for retrocomputing hardware. Each is a test of the programmer’s skill in fitting the most into the least of resources, and for those who appreciate such things it’s the cleverness of the technique which produces the demo that’s as much a draw as the look of the thing. I don’t think I have ever exercised such mastery over any of the computers I have owned. So browse the entries, and marvel at their ingenuity. My personal aesthetic favourites were Thrive by [Agenda] for the TIC-80 fantasy console and It’s about time by [Guideline] for Windows, but you may have different tastes.

Don’t Forget The Hardware

Beyond the atmosphere and the demos themselves, there was a bit of hardware for the retrocomputer enthusiast. The Atari Falcon and Jaguar were neither destined to set the world on fire when they appeared, but there they were for those of us who drooled over them back in the day to lust for once more.

If the original hardware wasn’t enough then there was some newly minted retrocomputing hardware making a showing, with a couple of minimig Amiga FPGA boards showing Workbench. Star of the hardware show though went to Mine Storm 4D, a version of the classic Vectrex game Mine Storm running on a PC, for the Looking Glass Factory holographic portrait display. With my visual superpower I didn’t quite get a 3D effect, but I definitely got the holographic effect when moving my head.

Having never been to a demo party I didn’t know quite what to expect, but I can safely say I had a fantastic time, saw a lot of really cool stuff, and made some friends along the way. If you’ve never been to a demo party because it’s not quite your scene then all I can say is that you should give it a go. Every hardware hacker should go to a demo party!

Hamvention 2022: The Reunion Begins Today

May 20, 2022 by Kristina Panos 7 Comments

Calling all hams! Hamvention 2022 is underway and runs through the weekend at the Greene County Fair and Expo Center in Xenia, Ohio. It’s been three long years since Hamvention took place in person, and this year marks the 70th reunion of what has got to be the largest hamfest in the Midwest. If you’re in the area, you don’t want to miss it. You will need a ticket, though, and here are a few places you pick one up.

Indoors, you’ll find six buildings full of commercial vendors. But outside is where the real fun takes place — the flea market. What treasures will you uncover? There’s only one way to find out.

If you want to get into ham radio, there’s no place like a ham fest to kick off your journey. And if you’ve been poring over the ARRL handbook, you’re in luck, because they’re proctoring ham exams for free at the church across the street on Friday and Saturday.

Can’t make it out for whatever reason, but live close to the fairgrounds? Want to get in the mood on your way there? Tune to 1620AM within a five-ish mile radius to hear weather, traffic, and parking info, plus interviews and other assorted radio fun. If you live nowhere near Ohio, don’t despair — they are livestreaming it on YouTube.

[Note: the Hara Arena, pictured in our awesome Joe Kim artwork, is the old home of Hamvention, and was demolished in 2016. Better head off to the Greene County Fairgrounds instead.]

Looking Forward To EMF Camp: Teasing Us With A Schedule

May 9, 2022 by Jenny List 5 Comments

As we gear up for a summer in the field, or more accurately in a series of fields, it’s time to turn our attention towards Eastnor Castle in the Western English county of Herefordshire, venue for the upcoming Electromagnetic Field hacker camp. Sadly we’ve got no badge to tease you with, but they’ve released a list of the talks that will fill their schedule. There are so many to choose from, we can only mention a few in this article.

We’ll certainly be taking the time to watch [Russell Couper] describe his electric motorcycle project. He’s no stranger to unusual bike builds, having given us a diesel machine at EMF 2016. Then of course there’s our own [Dave Rountree], who will be hacking the radio spectrum with GNU Radio. Sure to be an interesting talk.

One feature of this camp we’re very interested in will be CuTEL, a wired copper telephone network on the field. We’ll be taking along our trusty GPO 746 to be part of it of course, but for those without one, there’s [Matthew Harrold]’s talk on building a copper telephone network in a field.

Our cursory scan of the list finishes up with [Alistair MacDonald] on how not to start a hackerspace. We’ve seen our fair share of hackerspace drama over the years, so whether this one causes pain for ex-hackerspace-directors or not, it promises to be informative for anyone in the hackerspace world.

At the time of writing there are still some EMF tickets for sale, so if the beginning of your June is free we can heartily recommend it. To get a flavour of the event, read our 2018 review.

The MCH2022 Badge Has Landed!

May 4, 2022 by Jenny List 2 Comments

As spring slowly slides into summer here in Europe where this is being written, the warm weather is a reminder that on the horizon are the summer’s crop of hacker camps. The largest European one this year will be the Dutch MCH2022 near the end of July, and to whet our appetite they’ve made public some details of their badge. And true to the past form of Dutch camps, it’s rather an impressive build.

Since this is another piece of work from badge.team it has the expected ESP32 module, but alongside it on the elegantly-designed PCB there’s an RP2040 and a Lattice ICE40UP5K FPGA. The ESP is there to run the badge team firmware which even includes backwards compatibility with the original SHA2017 badge, the RP2040 ties everything together and provides a multitude of USB peripherals, and the FPGA is there to run user code. From the front, the badge has a Game Boy Advance-style form factor with a large colour TFT screen and the usual joystick and buttons. Other peripherals include a brace of addressable LEDs, a pair of nifty sensors from Bosch, and a 16-bit stereo audio channel that even powers a small onboard mono speaker when no headphones are connected.

The hardware may be slick, but it’s the badge.team firmware that makes this as special as all their previous offerings. It offers the chance to easily write apps either in MicroPython for the ESP32, or as payloads for the FPGA, and what makes it special is that it comes with an online app store from which all the apps can be downloaded. We’re told that it will be able to run a range of emulators out of the box, so we’re really looking forward to seeing the final version at the event. Meanwhile they’ve released a demo video that you can see below the break, and if you’re curious you can take a look at its SHA2017 badge ancestor.

Vintage Computer Festival East Raises The Bar Again

May 2, 2022 by Tom Nardi 34 Comments

When I arrived at the InfoAge Science and History Museum for this year’s Vintage Computer Festival East, I fully expected it to be a reduced event compared to last year. After all, how could it not? Due to the schedule getting shifted around by COVID, show runner Jeffrey Brace and his team had just six months to put together an event that usually gets planned over the course of an entire year. With such a truncated preparation time, they more than deserved a little slack.

But as anyone who attended VCF East 2022 can attest, they didn’t need it. Not only did the event meet the high expectations set by last year’s Festival, it managed to exceed them. There were more workshops, more talks, more vendors, more consignment rooms, more live streams, more…well, everything. This year’s program even got a splash of glossy color compared to the grayscale handout attendees received in October. It was, by any metric you care to use, better than ever.

It does however leave me in somewhat on an unenviable position. As we’ve learned during the pandemic, a virtual representation of an event as extensive as VCF can give you a taste of what’s offered, but all the nuance is lost. Looking at pictures of somebody’s passion project can’t compare to actually meeting the person and seeing that glint of pride in their eye as they walk you through all the details.

So bear that in mind through this rundown of some of the projects that caught my eye. This isn’t a “best of” list, and the Festival is certainly not a competition. But each attendee will invariably come away with their own handful of favorite memories, so I’ll document mine here. If you’d like to make your own memories, I’d strongly suggest making the trek out to the Jersey Shore come April 2023 for the next Vintage Computer Festival East.

Vintage Computer Festival East Is This Weekend

April 18, 2022 by Tom Nardi 1 Comment

This weekend the InfoAge Science and History Museum in Wall, New Jersey will once again play host to the Vintage Computer Festival East — the annual can’t-miss event for anyone who has even a passing interest in the weird and wonderful machines that paved the way for the supercomputers we now all carry around in our pockets. Ticket holders will have access to a program absolutely jam packed with workshops, talks, and exhibits that center around the dual themes of “Women in Computing” and “Computers for the Masses”, plus a consignment and vendor area that almost guarantees you’ll be going home a little poorer than when you got there. But hey, at least you’ll have some new toys to play with.

For those that can’t make the pilgrimage to the tropical wonderland that is the Jersey Shore in April, all three days of the Festival will be live-streamed to the VCF YouTube page. There’s even an official Discord server where you can chat with other remote attendees. We’re glad to see more events adopting a hybrid approach after two years of COVID-19 lockdown, as it gives the far-flung a chance to participate in something they would otherwise miss completely. That said, there’s no virtual replacement for the experience of browsing the exhibits and consignment areas, so if it’s at all possible we recommend you get yourself to InfoAge for at least one of the days.

Incidentally, don’t worry if you’ve got the sneaking feeling that it hasn’t been anywhere near a year since the last time the VCF descended on Wall Township. The 2021 Festival got pushed to October because of the lingering plague, but rather than permanently change the date going forward, the 2022 Festival has returned to its traditional season. Of course that means the wait until VCF 2023 will seem unusually long after this double-shot, so here’s hoping we see another swap meet at the InfoAge campus before the end of the year.

The 555 Gives The CarolinaCon Badge Life

April 17, 2022 by Jenny List 1 Comment

For the electronic badge enthusiast, these last two years have seen something of a famine. While the pandemic may not be over yet, we’re learning to live with it in 2022, and there’s the prospect of a flush of new badges even if not all events are in-person yet. First to reach us is the Carolinacon Online 2 badge, a fairly simple affair which naturally has us pleased as punch because it incorporates the only chip that’s guaranteed to get you through the semiconductor shortage, an NE555 timer. It’s got everything, a flashing LED, and, well, that’s it because with the best will in the world a 555 is no powerhouse on its own. As a memento and a way to support the event it fits the bill, but it’s fair to say that this is no electronic tour de force.

Carolinacon Online 2 launches on Friday 29th of April, and features a schedule of talks and a set of merch including the badge. If you’re thinking of previous Carolinacon badges, this event has always taken the simple-but-effective route. The version they produced in 2021 for example had a hidden message behind the silkscreen, revealed through clever placement of LEDs controlled by an ATtiny microcontroller.
