Ahmed Mohammed Clock is a FRAUD (?)(r/videos)
Here is the clock in question: a MICRONTA 63-765A Digital Alarm Clock with Battery Backup. The circuitry inside A.M.’s device matches perfectly with what you would expect from this clock; aside from the obvious red four-number seven-segment display:
The larger PCB has a fairly visible set of buttons on its top face (looking like silver circles or bumps) matching the control buttons of the clock (one on the far left = large ‘snooze’ button on clock; four smaller buttons offset-left from mid = ‘hour’, ‘time’, ‘min’, and ‘alarm’ buttons on clock, etc.
The size of the clock, about 8″ in length, matches the size of the ‘metal briefcase’-style pencil cases that they sell cheap in department stores; this one on Amazon is pretty standard at a little over 8″ in length, and matches the features pretty closely, minus maybe the clasp (although that was brought up in at least one interview with A.M. as having been modified anyway).
