An Unconference Badge That’s Never Gonna Give You Up

When your publication is about to hold a major event on your side of the world, and there will be a bring-a-hack, you abruptly realise that you have to do just that. Bring a hack. With the Hackaday London Unconference in the works this was the problem I faced, and I’d run out of time to put together an amazing PCB with beautiful artwork and software-driven functionality to amuse and delight other attendees. It was time to come up with something that would gain me a few Brownie points while remaining within the time I had at my disposal alongside …read more http://pje.fyi/PpQPnC

Make A Badge When There Is No Badge Yet

What do you do when your keenly anticipated hacker camp releases details of its upcoming badge and you really want to have a go at coding for it, but there are no badges for you to try yet? If you are [Artdanion], this is not a problem, you simply build your own.

He found his requirement to interface with genuine hardware exceeded the abilities of the emulator that the SHACamp 2017 badge team had thoughtfully provided, so he reached for breakout boards for the ESP32, the MPR121 touch sensor, and the e-ink display, and assembled his own clone on a …read more http://pje.fyi/Ph58xv

Hands On With The SHACamp 2017 Badge

The badge has become one of the defining features of a modern hacker camp, a wearable electronic device that serves as both event computer and platform for some mild software and hardware hacking. Some events have had astoundingly sophisticated badges while others are more simple affairs, and the phenomenon has even spawned an ecosystem of unofficial badges which have nothing to do with the event in question.

The SHACamp 2017 badge is the latest to come the way of a Hackaday writer, and certainly contains enough to be taken as representative of the state of hacker camp badges in 2017. …read more http://pje.fyi/Pfyk4L

Retro DEF CON Badge Made From ’80s Parts

DEF CON 25’s theme was retro-tech, and [xres0nance] wasn’t kidding around in the retro badge he built for the convention. The badge was mostly built out of actual parts from the ’80s and ’90s, including the perfboard from Radio Shack—even the wire and solder. Of the whole project just the resistors and 555 were modern parts, and that’s only because [xres0nance] ran out of time.

[xres0nance]  delayed working on the badge until his flight, throwing the parts in a box, and staggering to the airport in the midst of a “three-alarm hangover”. He designed the badge on the plane, downloading …read more http://pje.fyi/PfG6p1

Edge-lit Pendants Show Two Layers are Better Than One

Engraved acrylic lights up nicely with LED lighting. Simply engrave clear acrylic with a laser engraver, then edge-light the acrylic and watch the engraving light up. This badge made by [Solarbotics] shows how they used this principle when creating some pendants for an event that performed particularly well in the dark.

The pendants they created have two engraved acrylic panels each, and that’s about it. Two LEDs and a CR2032 battery nestle into pre-cut holes, and the engraved sides are placed face-to-face, so the outer surfaces of the pendant are smooth. By using some color-cycling RGB LEDs on one panel …read more http://pje.fyi/PbQw57

Building a DEF CON Badge in Two Weeks

DEF CON is starting right now, and this is the year of #badgelife. For the last few years, independent hardware wizards have been creating and selling their own unofficial badges at DEF CON, but this year it’s off the charts. We’ve already taken a look at Bender Badges, BSD Puffer Fish, and the worst idea for a conference badge ever, and this is only scratching the surface.

This is also a banner year for the Hackaday / Tindie / Supplyframe family at DEF CON. We’re on the lookout for hardware. We’re sponsoring the IoT village, [Jasmine] — the high …read more http://pje.fyi/PZxHnV

DEF CON Badgelife: Someone Finally Did It

Badgelife is the celebration of electronic conference badges, a way of life that involves spending far too much time handling the logistics of electronics manufacturing, and an awesome hashtag on Twitter. Badgelife isn’t a new thing; it’s been around for a few years, but every summer we see a massive uptick in the lead up to Def Con.

For the last few years, the designers and engineers deep into Badgelife have had the same conversation dozens of times. One person says, “you know, someone should build a badge that’s a quadcopter.” Another person replies, “Can you imagine how annoying that …read more http://pje.fyi/PX55nS
