The devboard is obviously a Texas Instruments MSP430 launchpad. Attached to it is a Bus Pirate used as a serial interface, and a round device of no obvious use… What could it be..?
Nicolas, the author of this challenge, explained that it is a simple display controlled by a servo. If you rotate the motor, the flag will be revealed underneath the red cover! To rotate the motor, you need to input a password via UART/Serial. Alright then, let’s get cracking – this is going to be fun.
