During the annual Hacker Summer Camp in Las Vegas hackers pour in from all the corners of the world to gather at DEFCON 27. During this time the Diana Initiative also held a conference for the third year in a row. The Diana Initiative is a conference aimed towards helping all who identify as women and nonbinary who are new or working in Information Security. The conference had amazing hands-on activities some of which were: learning to lockpick with the talented crew from LockpickExtreme , and the soldering village to build the Red Gem Badge. 

The Red Gem Badge was designed, programmed, built and tested by Chris who goes by TechGirlMN on Twitter. She also helped the attendees assemble the badge. If you would like the instructions for how to build the Red Gem Badge the instructions can be found over at this google drive. For this post, we will focus on the activities at the soldering village at Diana Initiative!

The soldering village was a room broken out into 4 big round tables. 3 of those tables where communal soldering stations meaning there were soldering irons, solder, other tools attendees would share to build the badge! The 3 tables ranged from beginner, intermediate to “expert” so people could choose their soldering comfort level to sit at. The 4th table was a components stations where attendees would grab a plastic cup, the badge and circle their way around the table picking the number of resistors, LEDS, buttons needed to build the badge.

The only component not given to the students was the Attiny85 until the instructor quality checked the board to ensure no cold joints, bridged connections, burned parts where present.

Here are the pictures of the instructions to build the Red Gem Badge which was powered by an Attiny 85 at Diana Initiative:

The Red Gem Badge Instruction Sheet was clear about pointing out what components were and where they are located in the badge for easy following.
