The 2020 eChallengeCoin

Redux !!

We have started assembling the second run of the 2020 eChallengeCoin!

The second round will not have the side plating (where the contact pads around the perimeter wrap from top to bottom). Instead, the edge will be stealth black!

The second run will have the same challenges and be compatible with the original batch so it's another chance to score the bonus!

What is it?

The is the 2020 eChallengeCoin. It is a challenge coin with 3 interactive challenges you solve using the LEDs and touch sensors, 3 story challenges you solve through the UART interface, and a bonus to unlock.

It comes fully assembled and ready to challenge your skills! It uses a standard CR2032 coin battery (included) and comes in a protective coin case.

Everything about the eChallengeCoin provides clues and misdirection.

It even has 3 demos to help you pass the time when you are not working on the challenges.

Why did you make it?

I wanted to create a badge for the DEFCON Conference.

I was familiar with the traditional challenge coins which signify a group of individuals or a significant event. But what about today's advanced technology groups, social engineering, InfoSec, or cyber security? Their challenge coin would be more than a static object. Their challenge coin would be electronic and have its own challenges!

That was the genesis of the idea to create the eChallengeCoin.

What makes it special?

The 2020 eChallengeCoin is about the size of a traditional challenge coin and is designed to be carried around in a pocket. It's just 44mm in diameter and the case only adds 10mm. It fits easily in a pocket but is also worthy of display. It is very energy efficient and will run off a standard CR2032 coin battery for several weeks.

It's also just the first!

The 2020 eChallengeCoin includes a story from The Adventures of Sara Cladlow. In the story, Sara encounters challenges which you must solve to continue. The story is accessed through the coin's UART connection - labeled TX, RX, and GND around the perimeter. Details and a video about the eChallengeCoin's story mode are available on the AoSC website.

There will be more eChallenge objects in the future - each will have interactive challenges and a new adventure for Sara Cladlow with new challenges to solve.

Is there more?

You can learn more about the 2020 eChallengeCoin at the ECC website. Check out the "Getting Started" video as well as videos on "Story Mode" and "Demo Modes".

While the actual source code would be spoilers, the sub-system code - ECC Core - has been made available under the MIT license.

IMPORTANT: The UART works with FTDI's using the CP210x chip. It does not work with several FTDI's using the FT232 chip. The reason defies logic. (FTDI not included.)
