Quote:Can you point out in the picture what makes it look like a bomb?

 

To me it looks like an LED display with four digits, and a couple of circuit boards that are obviously for driving the display, power supply and his clock circuit.  I don't see anything explosive in the picture, and it is housed in a small case.  The picture kind of makes it look like it is "brief case size", but use the plug as a reference.  It's about the size of a pack of cigarettes.

 

Full disclosure, my background is electronics and programming.
