BrickUsingMultipleModules (short: *BUMM*) is a riddle game themed around bomb defusals. After an evening of playing Keep talking and nobody explodes I was sure that this has to be transferred to hardware. The goal of defusing multiple modules is the same, but the hardware implementation calls for some serious changes. Cutting wires was out of the question, since nobody was found to replace them for a new round.

Bus Backplane. Why cut the copper stripes if we only need 5 signals (GND, 5V, Tx, Rx, 12V) anyway?
Speaker for beeping and firmly mounted audio amplifier
Bus backplane and usb-serial converter
On the last Make Rhein-Main, we had lots of power outages. Not stopping this device!
Remote control with countdown, life counter, serial number, configuration and status for each module

Background
Each module has its own arduino and is connected to a parallel bus backplane (speaking 5V UART at 19200 baud). Each module contains its own logic and only tells the gamemaster whether it has been defused and if any manipulations (mistakes) were detected.
The gamemaster is a Raspberry Pi running a python script. Apart from the game logic and audio output, it opens a TCP socket which can be used to control the game remotely. The network protocol is based on tree structures serialized to JSON and terminated with NULL.
All lookuptables and manuals are generated completely automatic from config files using python and make.
All material, be it gamemaster scripts, arduino code, *.tex for manuals or svg files for lasercutting are available on github.
Manuals
Make Rhein-Main 2017
BUMM was present on the Make Rhein-Main 2017 - bringing a bomb mockup to a fair - what could possibly go wrong? There is also a short clip.
Chamber for the BUMM
Inside the chamber there is also a video camera with live feed to our booth and an FF-OB/ZB field telephone
Lots of notes have been taken
