Around these parts, projects needlessly using a microcontroller where a simpler design would do are often derided with the catch-all “Should have used a 555,” even if the venerable timer chip wouldn’t have been the ideal solution. But the sentiment stands that a solution more complicated than it needs to be is probably one that […]
When we decided that Simple Add-Ons (SAOs) would be the focus of Supercon 2024, it was clear the badge would need to feature more than just one or two of the requisite connectors. We finally settled on six ports, but figuring out the geometry of getting all those ports on the badge in such a […]
With 2024 now officially in the history books, it’s time to take our traditional look back and reflect on some of the top trends and stories from the past twelve months as viewed from the unique perspective Hackaday affords us. Thanks to the constant stream of tips and updates we receive from the community, we’ve […]
[David Bryant] clearly has an awareness of the impact of an excess concentration of CO2 in the local environment and has designed an SAO board to add a CO2 traffic light indicator to one of the spare slots on the official Hackaday Supercon 2024 badge. The part used is the Sensirion SCD40 ‘true’ CO2 sensor, […]
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 […]
Generally speaking, the Hackaday Supercon badge will always have a place for SAO (rebranded as “Supercon add-ons”), and that makes sense. We did originate them, after all. This year, though, we’ve gone all in on SAO, and, in particular, we’ve asked to see more SAOs with communication capabilities. The standard has always had an I2C […]
More than a couple folks have written us saying that their entries into the Supercon Add-On Contest got caught up in the Chinese fall holidays. Add to that our tendency to wait until the last minute, and there still more projects out there that we’d like to see. So we’re extending the deadline one more […]
For some of us, the Speak ‘n Spell evokes pleasant memories of childhood as our first computer, along with one of those Merlin things. For others, it’s the ultimate circuit bending victim. For [Jeremy Geppert], they’re all-around good fun and he wanted to immortalize the device in a Simple Add-On (SAO). This is [Jeremy]’s first […]
For this contest, we’re asking you to come up with the best SAO you can think of that does something cool. What could be cooler than sharing your contact information all over Supercon and beyond with a tap of a Jolly Wrencher? It’s way better than just some sticker, and with the extra solder pad […]
Core memory, magnetized memory using tiny magnetic rings suspended on a grid of wires, is now more than five decades obsolete, yet it exerts a fascination for hardware hackers still. Not least [Andy Geppert], who’s made a nibble, four bits of it, complete with interactive LED illumination to show state. Best of all, it’s on […]
