The Badge Hacks Of Supercon

November 9, 2024 by Elliot Williams 4 Comments

We just got home from Supercon and well, it was super. It was great to see everyone, and meet a whole bunch of new folks to boot! The talks were great, and you can see a good half of them already on the Hackaday YouTube channel, so for that you didn’t even have to be there.

The badge hacks were, as with most years, out of this world. I’ll admit that my cheeks were sore from laughing so much after emceeing it this year, due in no small part to two hilarious AI projects, both of which were also righteous hacks in addition to full-on comedy routines. A group of six programmers got all of their hacks working together, and the I2C-to-MQTT bridge had badges blinking in sync even in the audience. You want blinkies? We had blinkies.

But the hack that warmed everyones’ hearts was “I figured it out” by [Connie]. Before this weekend, she had never coded MicroPython and didn’t know anything about I2C. But yet by Sunday afternoon, she made a sweet spiral animation on the LED wheel, and blinked the RGBs in the touchwheel.

What I love about the Hackaday audience is that, when the chips are down, someone doing something new for the first time is valued as much as some of the more showy work done by more experienced programmers. Hacking is also about learning and pushing out boundaries after all. The shouts for “I figured it out” were louder than any others in the graphics hacks category, it took home a prize, and I was smiling from ear to ear.

Hackaday can learn from this too. [Connie]’s hack definitely shows the need for another badge-hack category, first timers, because we absolutely should recognize first tries. There was also a strong petition / protest from people who had worked new hacks onto previous year’s badges – like [Andy] and [koppanyh]’s addition of bit-banged I2C to the Voja 4 badge from two years ago, and [Instant Arcade]’s Polar Pacman, which he named “Ineligible for this Competition” in protest. Touche.

We’re stoked to learn new things, see new hacks, and basically just catch up with everything folks did over the weekend. We can’t wait to see what you’re up to next year!

Supercon 2024: Badge Add-On Winners

November 4, 2024 by Tom Nardi 5 Comments

This year we challenged the Hackaday community to develop ~~Shitty~~ ~~Simple~~ Supercon Add-Ons (SAO) that did more than just blink a few LEDs. The SAO standard includes I2C data and a pair of GPIO pins, but historically, they’ve very rarely been used. We knew the talented folks in this community would be able to raise the bar, but as they have a tendency to do, they’ve exceeded all of our expectations.

As we announced live during the closing ceremony at the 2024 Hackaday Supercon, the following four SAOs will be put into production and distributed to all the attendees at Hackaday Europe in Spring of 2025.

Supercon 2024 Flower SAO Badge Redrawing In KiCad

October 31, 2024 by Chris Lott 12 Comments

Out of curiosity, I redrew the Supercon Vectorscope badge schematics in KiCad last year. As you might suspect, going from PCB to schematic is opposite to the normal design flow of KiCad and most other PCB design tools. As a result, the schematics and PCB of the Vectorscope project were not really linked. I decided to try it again this year, but with the added goal of making a complete KiCad project. As usual, [Voja] provided a well drawn schematic diagram in PDF and CorelDRAW formats, and a PCB design using Altium’s Circuit Maker format (CSPcbDoc file). And for reference, this year I’m using KiCad v8 versus v7 last year.

Importing into KiCad

This went smoothly. KiCad imports Altium files, as I discovered last year. Converting the graphic lines to traces was easier than before, since the graphical lines are deleted in the conversion process. There was a file organizational quirk, however. I made a new, empty project and imported the Circuit Maker PCB file. It wasn’t obvious at first, but the importing action didn’t make use the new project I had just made. Instead, it created a completely new project in the directory holding the imported Circuit Maker file. This caused a lot of head scratching when I was editing the symbol and footprint library table files, and couldn’t figure out why my edits weren’t being seen by KiCad. I’m not sure what the logic of this is, was an easy fix once you know what’s going on. I simply copied everything from the imported project and pasted it in my new, empty project.

Hackaday Podcast Episode 294: SAO Badge Reveal, Precision On A Shoestring, And The Saga Of Redbox

October 25, 2024 by Tom Nardi No comments

With the 2024 Hackaday Supercon looming large on the horizon, Editors Elliot Williams and Tom Nardi start this episode off by talking about this year’s badge and its focus on modular add-ons. From there they’ll go over the results of a particularly challenging installment of What’s that Sound?, discuss a promising DIY lathe that utilizes 3D printed parts filled with concrete, and ponder what the implosion of Redbox means for all of their disc-dispensing machines that are still out in the wild.

You’ll also hear about custom macropads, lifting SMD pins, and how one hacker is making music with vintage electronics learning kits. Finally, they’ll reassure listeners that the shifting geopolitical landscape probably won’t mean the end of Hackaday.io anytime soon, and how some strategically placed pin headers can completely change how you approach designing your own PCBs.

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!

The 2024 Hackaday Supercon SAO Badge Reveal

October 22, 2024 by Elliot Williams 25 Comments

We’ve been hinting at it for a few months now, running a series of articles on SAOs, then a Supercon Add-On Challenge. We even let on that the badge would have space for multiple SAOs this year, but would you believe six?

Way back in 2017ish, Hackaday’s own [Brian Benchoff] and the [AND!XOR] crew thought it would be funny and useful to create a “standard” for adding small custom PCB art-badges onto bigger conference badges. The idea was to keep it quick and dirty, uncomplicated and hacky, and the “Shitty” Add On was born. The badge community took to this like wildfire. While the community has moved on from the fecal humor, whether you call these little badgelets “SAOs”, “Simple Add-Ons”, or even “Supercon-8 Add Ons”, there’s something here for everyone. So if you’ve already got some SAOs in a drawer, bring them to this year’s Supercon and show them off!

The JawnCon 0x1 Badge Dials Up A Simpler Time

September 16, 2024 by Tom Nardi 10 Comments

For hackers of a certain age, the warbling of an analog modem remains something of a siren song. Even if you haven’t heard it in decades, the shrill tones and crunchy static are like a time machine that brings back memories of a bygone era. Alien to modern ears, in the 1980s and 90s, it was the harbinger of unlimited possibilities. An audible reminder that you were about to cross the threshold into cyberspace.

If you can still faintly hear those strangely comforting screeches in the back of your mind, the JawnCon 0x1 badge is for you. With a row of authentic vintage red LEDs and an impeccably designed 3D-printed enclosure, the badge is essentially a scaled-down replica of the Hayes SmartModem. But it doesn’t just look the part — powered by the ESP8266 and the open source RetroWiFiModem project, the badge will allow attendees to connect their modern computers to services from the early Internet via era-appropriate AT commands while they’re at the con.

There’s Already A Nixie Addon For The 2024 Supercon Badge

September 12, 2024 by Lewin Day No comments

Nixie tubes are cool, and hackers like them. Perhaps for those reasons more than any other, [Kevin Santo Cappuccio] has developed a very particular Simple Add-On for the 2024 Hackaday Supercon badge.

The build began with a Burroughs 122P224 Nixie tube, and a HV8200 power supply. The latter component is key—it’s capable of turning voltages as low as 3 V into the 180V needed to power a Nixie. Then, an 18-position selector switch was pulled out of a resistance substitution box, and [Kevin] whipped up a basic DIY slip ring using some raw copper clad board.

Smoosh it all together, and what do you get? It’s a Nixie tube you can spin to change the number it displays. Useful? Hardly, unless you want to display varying glowing numbers to people at unreadable angles. Neat? Very. Just don’t touch any of the pins carrying 180 V, that’ll sting. Still, [Kevin] told us it’s pretty tucked away. “I’m totally comfortable touching it, but also would get sued into oblivion selling these on Amazon,” he says.

As [Kevin] notes in his post, the 2024 badge is all about the add-ons— and there’s actually a contest! We suspect [Kevin] will have a strong chance of taking out the Least Manufacturable title.

If you need more information about the Simple Add-On (SAO) interface, [Brian Benchoff] posted the V1.69bis standard on these very pages back in 2019. Apparently the S used to stand for something else. Video after the break.
