There’s a line from the original Star Trek where Khan says, “Improve a mechanical device and you may double productivity, but improve man and you gain a thousandfold.” Joan Horvath and Rich Cameron have the same idea about improving education, particularly autodidacticism or self-learning. They share what they’ve learned about acquiring an intuitive understanding of difficult math at the Hackaday Superconference and you can watch the newly published video below.
The start of this was the pair’s collaboration on a book about 3D printing science projects. Joan has a traditional education from MIT and Rich is a self-taught guy. This …read more
Every year at Superconference, Editor-in-Chief Mike Szczys gets the chance to talk about what we think are the biggest, most important themes in the Hackaday universe. This year’s talk was about science and technology, and more importantly who gets to be involved in building the future. Spoiler: all of us! Hackaday has always stood for the ideal that you, yes you, should be taking stuff apart, improving it, and finding innovative ways to use, make, and improve. To steal one of Mike’s lines: “Hackaday is an engine of engagement in engineering fields.”
The obvious way that we try to push …read more
Chris Gammell wants to know: What’s in your circuit toolbox?
Personally, mine is somewhat understocked. I do know that in one of my journals, probably from back in the 1980s, I scribbled down a schematic of a voltage multiplier I had just built, with the classic diode and capacitor ladder topology. I probably fed it from a small bell transformer, and I might have gotten a hundred volts or so out of it. I was so proud at the time that I wrote it down for posterity with the note, “I made this today!”
I think the whole point of …read more
Voja Antonic designed this fantastic retrocomputing badge for Hackaday Belgrade in 2018, and it was so much fun that we wanted to bring it stateside to the Supercon essentially unaltered. And that meant that Voja had some free time to devote to a new hardware giveaway: the Cube. So while his talk at Supercon in November was ostensibly about the badge, he just couldn’t help but tell us about his newer love, and some of the extremely clever features hidden within.
It’s funny how the hardware we design can sometimes reflect so much on the creator. Voja designed then-Yugoslavia’s first …read more
It’s fair to say that the majority of Hackaday readers have not built any hardware that’s slipped the surly bonds of Earth and ventured out into space proper. Sure we might see the occasional high altitude balloon go up under the control of some particularly enterprising hackers, but that’s still a far cry from a window seat on the International Space Station. Granted the rapid commercialization of space has certainly added to that exclusive group of space engineers over the last decade or so, but something tells us it’s still going to be quite some time before we’re running space-themed …read more
You can define the word crazy in myriad ways. Some would say using SMD resistors and QFN microcontrollers as structural elements is crazy. Some would say hand soldering QFN is crazy, much less trying to do it on edge rather than in the orientation the footprint is designed for. And of course doing it live on stage in front of people who eat flux for breakfast is just bonkers. But Zach did it anyway and I’m delighted he did.
This is the cyborg ring, and it’s a one-of-a-kind leap in imagination — the kind of leap people have come to …read more
If you want to build hundreds of a thing (and let’s face it, you do) now is a magical time to do it. Scale manufacturing has never been more accessible to the hardware hacker, but that doesn’t mean it’s turn-key with no question marks along the way. The path is there, but it’s not well marked and is only now becoming well-traveled. The great news is that yes, you can get hundreds of a thing manufactured, and Kerry Scharfglass proves that it’s a viable process for the lone-wolf electronics designer. He’s shared tips and tricks of the manufacturing process in …read more
Ben Krasnow has a vision of future electronics: instead of the present PCB-screwed-into-a-plastic-box construction, flexible circuits will be deposited straight onto the plastic body of the device itself, merging the physical object and its electronics. There is existing copper-on-plastic technology, but Ben’s got something novel that he presents in this talk that you could implement yourself. You might also want a display, or at least something to blink, so he’s also working on some electroluminescent technology to complement it. If you were wondering why Ben is so interested in silkscreening photopolymers right now, watching this talk will pull a lot …read more
The Hackaday Superconference is all about showcasing the hardware heroics of the Hackaday community. We also have a peer-reviewed journal with the same goal, and for the 2018 Hackaday Superconference we got a taste of the first paper to make it into our fully Open Access Journal. It comes from Ted Yapo, it is indeed a tale of hardware heroics: what happens when you don’t want to spend sixty thousand dollars on a vector network analyzer?
Ted’s talk begins with a need for a network analyzer. These allow for RF measurements, but if you ever need one, be prepared: you …read more
Writing this in the frigid darkness of a Northern Hemisphere January evening, I have to admit to more than a little envy of Samy Kamkar and his friends. One of their summer events is a private party at a secluded campground somewhere that looks quite warm, which from here seems mighty attractive.
Samy wanted to provide a spectacle for his friends. What he came up with is glowing orbs; LED balloons that would float above the campsite and wow his friends with their pretty synchronised illumination. Thus an adventure in wireless communications, lighter-than-air flammable gasses versus electronics weight calculations, and …read more
