At Hackaday, we get notified of a lot of the cool events going on in hackerspaces all around the world. We’d like to keep you informed too, just in case there’s something going on in your neighborhood.
Our 2014 adventures were so much fun that it drove us to create our own hacking challenge in 2015 to cobble together a <$100 HF SSB transceiver (made in the USA for extra budget pressure), an ad-hoc antenna system, put this on the air, and make an out-of-state contact before the end of Hamvention using only parts and gear found at Hamvention. There’s no time to study manuals, antennas, EM theory, or vacuum tube circuitry. All you have are your whits, some basic tools, and all the Waffle House you can eat. But you have one thing on your side, the world’s largest collection of surplus electronics and radio junk in one place at one time. Can it be done?
This weekend is the Vintage Computer Festival East in Wall, New Jersey. Every year is different, but there’s a general plan for each day. On Saturday and Sunday, the exhibits rule the con, the consignment shop is busy, and the keynotes bring down the house. Friday is a little different. This is the day for ‘in the trenches’ talks from the commodore crew, classes on recapping 30-year-old computers, and this year – for the first time – a retro hackathon. It’s basically the same format as any other hackathon, but instead of bringing MacBooks and building something cool, Apple IIs and Commodore 64s were provided. This is the report on the first retro hackathon we’ve ever been to.
First off, no one remembers how to program in BASIC. If you’re looking for a population that should remember the vagaries of the different dialects of BASIC, you would think it would be the people who came out to the middle of Jersey on Friday to talk about old CPUs. Apparently, this is not the case and several people were confused about single and double quotes in PRINT statements. Luckily, a few programming manuals for the C64 and Apple II were available, so everyone could still have fun with PEEKs and POKEs.
If you want to get people programming on some old machines, you need to give them some inspiration. The first half hour of the retro hackathon didn’t see any teams programming. Given this demographics proclivity to say, ‘I can do that better’, I typed a few BASIC one-liners in the C64 (random Truchet tiles in PETSCII) and Apple II (a SIN graph), and the people started pouring in. Yes, they could program something better than a single line of BASIC.
Sound on an Apple IIc.
What came of an impromptu retro hackathon? Hangman, in BASIC. No, it didn’t quite work, and there were only three or four possible words hardcoded into the program. Still, text mode graphics are a lost art. The Apple IIc was programmed to make fart noises. The original plan for this project was to program music. What would have been the winning entry was a line-drawing program on the C64 that looked like the enemy in Qix. That guy wasn’t there during judging. The winner of a $50 credit to the consignment shop was a kid who programmed zero-player Pong on Apple II basic. He bought a Mac Portable (non-backlit) with that prize.
We’ve gone to hackathons, we’ve waded through the sea of MacBooks, and had a Red Bull drip installed. This retro hackathon was completely different, but somehow familiar. No, no one is going to create something new – everything that can be done on these machines in a few hours of BASIC programming has already been done. That’s not the point, though. It’s a geek pride of proving your mettle, putting your money where your mouth is, and doing it in a casual environment where everyone is friendly. This is the first retro hackathon we’ve gone to, and it won’t be the last. We’re going to do this again, once we get an Apple IIc+, a few Commodores, a Speccy, and a few good monitors. We already have the banner, anyway.
Troy New York’s Tech Valley Center of Gravity is following up their January IoT Hackathon with another installment. The April 16-17 event promises to be a doozy, and anyone close to the area with even a passing interest in gaming and AR/VR should really make an effort to be there.
Not content to just be a caffeine-fueled creative burst, TVCoG is raising the bar in a couple ways. First, they’re teaming up with some corporate sponsors with a strong presence in the VR and AR fields. Daydream.io, a new company based in the same building as the CoG, is contributing a bunch of its Daydream.VR smartphone headsets to hackathon attendees, as well as mentors to get your project up and running. Other sponsors include 1st Playable Productions and Vicarious Visions, game studios both located in the Troy area. And to draw in the hardcore game programmers, a concurrent Ludum Dare game jam will be run by the Tech Valley Game Space, with interaction and collaboration between the AR/VR hackers and the programmers encouraged. Teams will compete for $1000 in prizes and other giveaways.
This sounds like it’s going to be an amazing chance to hack, to collaborate, and to make connections in the growing AR/VR field. And did we mention the food? There was a ton of it last time, so much they were begging us to take it home on Sunday night. Go, hack, create, mingle, and eat. TVCoG knows how to hackathon, and you won’t be disappointed.
Thanks to [Duncan Crary] for the heads up on this.
What’s not to love about a hackathon? The junk food and caffeine that fuel the weekend; the highs that come with success and the lows that come when the blue smoke is released; the desperate search for inspiration as the clock ticks away; nerve-wracking pitches to the judges, hoping against hope that everything works in the demo. Hackathons are the contact sport of the hacker world, bringing in top competitors and eager upstarts, and when done well you just might attract interested “civilians” and other newbies that will catch the hacking bug from what they witness.
Such was the scene at the Tech Valley Center of Gravity in Troy, NY over the last weekend of January. New for 2016, the CoG is hosting a series of four hardware hackathons this year, each with a different theme. This event’s theme was “Internet of Things”, and the call went out to any and all to come compete for bragging rights and over $1,000 in prizes. Incentives to compete included some big name corporate sponsors, like AT&T, and judging and mentoring provided by the likes of SparkFun’s [Jeff Branson]. There was also a steady stream of food and drink, saturation coverage by local media outlets, and your humble Hackaday writer and his son, who made the trip up to Troy with a small passel of Hackaday swag and a curiosity to see how the CoG has fared since our last visit at the grand opening of their glorious new home. We were not disappointed.
Measuring the body’s electrical signals is a neat trick… if you can get your equipment dialed in enough to establish dependable measurements. The technique is called Surface ElectroMyography (SEMG) though you’ll hear many call this ECG. They’re essentially the same technology; the Electro CardioGraph instruments monitor the activity of the heart while SEMG Instruments monitor electrical signals used to control other muscles. Both types of hardware amount to an instrumentation type amplifier and some form of I/O or display.
This topic has been in my back pocket for many months now. Back in May we Hackaday’ites descended on New York City for the Disrupt NY Hackathon event. We arrived a day or so early so that we might better peruse the Korean BBQ joints and check out the other electronics that NY has to offer. On Saturday we gathered around, each shouting out the size of his or her t-shirt preference as we covered up our black Hackaday logo tees with maroon maroon ones (sporting the Hackaday logo of course) for a 24-hour craze of hardware hacking.
There were two individuals at our tables who were both hacking away on hardware to measure the electrical field produced by the body’s muscles in some form or another. The electrical signals measured from the skin are small, and need careful consideration to measure the signal despite the noise. This is a fun experiment that lets you work with both Instrumentation Amplifiers and OpAmps to achieve a usable signal from the movement of your body.
Big-name corporate sponsors, top-notch judges and mentoring, 36 hours to play in a huge new hackerspace, and all the Cheetos and Red Bull you need to stoke the creative fires. Sounds like a hackathon, and it’ll roll into The Tech Valley Center of Gravity in Troy, New York next month. And from the look of it, it’s going to be a big deal. You should be there.
You might recall the TVCoG from a story we did this summer on the grand opening of their amazing newly renovated space in downtown Troy. Occupying an entire city block in a historic department store building and housing not only a huge hackerspace but a tech company incubator with manufacturing capabilities and a STEM outreach space, the CoG now has the room to reach out into the community and host big events. The hackathon scheduled for January 30 and 31 and is only the first of four events planned for 2016. This one has the theme “Internet of Things” and will feature SparkFun’s Jeff Branson as mentor and judge.
Here’s a call to arms for Hackaday readers in the northeast: let’s pack this hackathon and make it huge. There’s already a bunch of Jolly Wrencher stickers scattered all over from our last visit, so you’ll feel right at home. Head over to the TVCoG site and sign up for this one. We’d really like to see HaD take home bragging rights. And you can be sure we’ll be covering the event and bringing some swag of our own.
