NoodleCon Badge

NoodleCon Badge

Hackaday Alum Sarah Petkus has been on a long quest to build an awesome robot with a lot of personality lovingly known as Noodle (check out her Hackaday Supercon talk on the adorable quadruped). For DC26 she decided to throw a con inside the con for Noodle and this is the badge.

Anyone following Sarah’s work knows that her art is on point and here is a great example. Look at the solder mask on front and rear and you’ll notice the lettering is mirrored. This gives it the appearance that this is a design you can see through the board. The bold use of patches of silk screen and gold-plated copper deliver her aesthetic boldly and make you just want to stare at the design. There is a little squiggle through the C on the front that is a superb touch! Driven by an ATmega328 and a CR2032, there are 10 LEDs on the back that flash for a backlight effect.

Competitive Soldering is Now a Thing

At Hackaday, we’re constantly impressed by the skill and technique that goes into soldering up some homebrew creations. We’re not just talking about hand-soldering 80-pin QFNs without a stencil, either: there are people building charlieplexed LED arrays out of bare copper wire, and using Kynar wire for mechanical stability. There are some very, very talented people out there, and they all work in the medium of wire, heat, and flux.

At this year’s DEF CON, we opened the floodgates to competitive soldering. Along with [Bunny] from Hardware Hacking Village and the many volunteers from the HHV and Soldering Skills Village, dozens competed to solder up a tiny kit full of LEDs and microscopic resistors.

The kit in question was an SMD Challenge Kit put together my MakersBox, and consisted of a small PCB, an SOIC-8 ATtiny, and a LED and resistor for 1206, 0805, 0603, 0402, and 0201 sizes. The contest is done in rounds. Six challengers compete at a time, and everyone is given 35 minutes to complete the kit.

E-Paper Badge is a Hint at Great Things to Come

E-Paper Badge is a Hint at Great Things to Come

Friend of Hackaday, Drew Fustini, came to our Breakfast at DEF CON meetup sporting a name badge of his own design. The E-Paper Badge uses a Teensy LC to drive a 2.15″ E-Paper display. The row of capacitive touch buttons to the left allow the image to be changed, and he just happened to have the Jolly Wrencher in the gallery of choices for this picture.

This badge gets me really excited for this year’s Open Hardware Summit which is at MIT on September 27th. This year’s badge is a collaborative effort between a group on Hackaday.io! It’s basically Drew’s badge on steroids, and he told me the experience of working with a team has been really positive. It seems each time the group hits a hard problem or a pile of work that needs to be done, someone on the team grabs it and runs with it. It’s a great example of both certified open hardware and team development.

DC26: overview of the DC503 party badge

An overview of the DC503 party badge as seen at DefCon 2018

Hi! My name is Nisha, and I made a party bangle for my friend, Miki, to take with her to DefCon25. It was my first fully-formed electronics project and it posed some interesting challenges due to its unusual form factor. You can read about my experiences with that project here.

Soon after DefCon25, I was approached by r00tkillah to make over a 100 of something similar for the DC503 party at DefCon26. The plan was to combine the power of the BMD-300 SoC by Rigado used in the Wagon Badge from the previous year with my Neopixel bangle form factor. We would call it “The Banglet” and it was going to be awesome.

In passive mode, the banglet’s LEDs light up when detecting nearby Bluetooth devices. The number of LEDs that are lit correspond to the number of BT devices detected and their colors are based on each device’s mac address.
