1. Assessment Device
Definition:A device designed totestthe wire accessingskillsof the operator underthe addedstressor
of time.Inside the case isaneightquestiontestpertainingtogeneral EODknowledge.The answersto
each questioncorrespondtoa wire’scolorinside the Ethernetcable. The colororderinwhichthe
operatoranswersinisthe same orderinwhichthe wiresmustbe cut. Once the case is openedanLCD
will indicate the amountof time remaining withastartingtime of eightminutes.
Hardware: ATMega328P (Arduino)
Arming: Plugthe powercable intothe wall andturn the keyswitchto on.
Firing:Time runs out,more than one wire cut out of order,pushingred microswitch,cuttingall wiresat
once,removingEthernetfromthe jack.
