VCF East 2024 Was Bigger And Better Than Ever

I knew something had changed before I even paid for my ticket to this year’s Vintage Computer Festival East at the InfoAge Science and History Museum in Wall, New Jersey.

Over the last couple of years, attendance has been growing to the point that parking in the lot directly next to the main entrance has been reserved for only the earliest of risers. That hasn’t described yours truly since the days when I still had what my wife refers to as a “real job”, so that’s meant parking in the overflow lot down the road and walking the half a mile or so back to the main gate. Penance for working on the Internet, let’s call it.

But this time, while walking along the fence that surrounds the sprawling InfoAge campus, I came across an open gate and a volunteer selling tickets. When commenting to her that this was a pleasant surprise compared to the march I’d anticipated, she responded that there had been so many people trying to get into the main entrance that morning that they decided to station her out here to handle the overflow.

I was a few steps past her table and into InfoAge before the implications of this interaction really hit me. Two entrances. How many attendees does there need to be before you setup a secondary ticket booth out by the reserve parking lot just to keep things moving smoothly? Well, I can’t tell you what the exact number is. But after spending the rest of the day walking between all the buildings it took to contain all of the exhibits, talks, and activities this year, I can tell you it’s however many people came to VCF East 2024.

Compared to its relatively humble beginnings, it’s incredible to see what this event has grown into. InfoAge was packed to the rafters, and despite what you might think about a festival celebrating decades old computing hardware, there were plenty of young faces in the crowd. I’m not sure exactly what’s changed, but the whole place was positively jumping. Perhaps it’s partially the generational nostalgia that’s kept Netflix cranking out new seasons of the 1980’s set Stranger Things. I’m sure attention (and attendance) from several well known YouTube personalities have played a big part as well.

Whatever the magic formula that’s turned what was once a somewhat somber retrospective on early desktop computers into a major destination for tech lovers, I’m all for it. Love Live the Vintage Computer Festival!

Human-Interfacing Devices: HID Over I2C

In the previous two HID articles, we talked about stealing HID descriptors, learned about a number of cool tools you can use for HID hacking on Linux, and created a touchscreen device. This time, let’s talk about an underappreciated HID standard, but one that you might be using right now as you’re reading this article – I2C-HID, or HID over I2C.

HID as a protocol can be tunneled over many different channels. If you’ve used a Bluetooth keyboard, for instance, you’ve used tunneled HID. For about ten years now, I2C-HID has been heavily present in laptop space, it was initially used in touchpads, later in touchscreens, and now also in sensor hubs. Yes, you can expose sensor data over HID, and if you have a clamshell (foldable) laptop, that’s how the rotation-determining accelerometer exposes its data to your OS.

Not every I2C-connected input device is I2C-HID. For instance, if you’ve seen older tablets with I2C-connected touchscreens, don’t get your hopes up, as they likely don’t use HID – it’s just a complex-ish I2C device, with enough proprietary registers and commands to drive you crazy even if your logic analysis skills are on point. I2C-HID is nowhere near that, and it’s also way better than PS/2 we used before – an x86-only interface with limited capabilities, already almost extinct from even x86 boards, and further threatened in this increasingly RISCy world. I2C-HID is low-power, especially compared to USB, as capable as HID goes, compatible with existing HID software, and ubiquitous enough that you surely already have an I2C port available on your SBC.

In modern world of input devices, I2C-HID is spreading, and the coolest thing is that it’s standardized. The standardization means a lot of great things for us hackers. For one, unlike all of those I2C touchscreen controllers, HID-I2C devices are easier to reuse; as much as information on them might be lacking at the moment, that’s what we’re combating right now as we speak! If you are using a recent laptop, the touchpad is most likely I2C-HID. Today, let’s take a look at converting one of those touchpads to USB HID.

Hackaday Links: April 14, 2024

The Great American Eclipse v2.0 has come and gone, sadly without our traveling to the path of totality as planned; family stuff. We did get a report from friends in Texas that it was just as spectacular there as expected, with the bonus of seeing a solar flare off the southwest limb of the disk at totality. Many people reported seeing the same thing, which makes us a bit jealous — OK, a lot jealous. Of course, this presented an opportunity to the “Well, ackchyually” crowd to point out that there were no solar flares or coronal mass ejections at the time, so what people saw wasn’t an exquisitely timed and well-positioned solar flare but rather a well-timed and exquisitely positioned solar prominence. Glad we cleared that up. Either way, people in the path of totality saw the Sun belching out gigatons of plasma while we had to settle for 27% totality.

PicoNtrol Brings Modern Controllers To Atari 2600

While there’s an argument to be made that retro games should be experienced with whatever input device they were designed around, there’s no debating that modern game controllers are a lot more ergonomic and enjoyable to use than some of those early 8-bit entries.

Now, thanks to the PicoNtrol project from [Reogen], you can use the latest Xbox and PlayStation controllers with the Atari 2600 via Bluetooth. Looking a bit farther down the road the project is aiming to support the Nintendo Entertainment System, and there’s work being done to bring the Switch Pro Controller into the fold as well.

Hackaday Podcast Episode 266: A Writer’s Deck, Patching Your Battleship, And Fact-Checking The Eclipse

Before Elliot Williams jumps on a train for Hackaday Europe, there was just enough time to meet up virtually with Tom Nardi to discuss their favorite hacks and stories from the previous week. This episode’s topics include the potential benefits of having a dual-gantry 3D printer, using microcontrollers to build bespoke note taking gadgets, the exciting world of rock tumbling, and the proper care and maintenance required to keep your World War II battleship in shape. They’ll also go over some old school keyboard technologies, DIP chip repairs, and documenting celestial events with your home solar array. By the end you’ll hear about the real-world challenges of putting artificial intelligence to work, and how you can safely put high-power lithium batteries to work in your projects without setting your house on fire.

Check out the links below if you want to follow along, and as always, tell us what you think about this episode in the comments!

Let Your Finger Do The Soldering With Solder Sustainer V2

Soldering is easy, as long as you have one hand to hold the iron, one to hold the solder, and another to hold the workpiece. For those of us not so equipped, there’s the new and improved Solder Sustainer v2, which aims to free up one of however many hands you happen to have.

Eagle-eyed readers will probably recall an earlier version of Solder Sustainer, which made an appearance in last year’s Hackaday Prize in the “Gearing Up” round. At the time we wrote that it looked a bit like “the love child of a MIG welder and a tattoo machine.” This time around, [RoboticWorx] has rethought that concept and mounted the solder feeder on the back of a fingerless glove. The solder guide is a tube that clips to the user’s forefinger, which makes much finer control of where the solder meets the iron possible than with the previous version. The soldering iron itself is also no longer built into the tool, giving better control of the tip and letting you use your favorite iron, which itself is no small benefit.

Hats off to [RoboticWorx] for going back to the drawing board on this one. It isn’t easy to throw out most of your design and start over, but sometimes it just makes sense.
