Product Description

If you liked the original black and red version of the Powers of Two Clock - you are going to go bi-serk with this fresh re-imaging of this binary time machine. -- Six rows of bright crystal blue LEDs are inlaid in a chrome body. The lights display hour, minute and second in binary code - the language of computers. Display can be in 12 or 24 hour modes. -- Once you understand the basics and after only a few moments of practice, you will have no trouble at all "decoding" the time by adding the values of LEDs in each column. -- When tired of watching the clock, you can just watch the constantly changing light display that creates thousands of unique mesmerizing patterns. -- Measures 3.5" x 3.5" x 2", weighs 10 oz. and comes with 120V adapter and instructions.

5.0 out of 5 stars Great gift, August 31, 2005

Great gift and conversation piece.
Pros: Small desktop device that catches the attention of everyone passing by. A fun challenge for the non-computer/math person.
Cons: It is sometimes difficult to read the time in low light as the positions of the LEDS are hard to identify (the illuminated LEDs are easily seen.) It could use a backup battery (although setting the time is easy)

5.0 out of 5 stars Nice Gift, December 24, 2004

This review is from: Powers of 2 BCD Clock (Kitchen)

I've seen this clock on display at the Discovery Channel Store and at first it looks like a little box with flashing lights. A sales associate explained to me how to read the clock and it actually makes sense. It's a perfect gift for someone who likes unusual things or for a computer geek. The Discovery Store use to sell this same model, but it doesn't sell it anymore so Amazon is the only place to get this model.

5.0 out of 5 stars True binary mode, March 10, 2008

This review is from: Powers of 2 BCD Clock (Kitchen)

This is a great product for computer science students or CS geeks in general. Note that it has a "true" binary mode where each row is used to represent hours, minutes and seconds (top row is ignored). The alternative mode uses vertical binary read-outs to represent individual digits of a traditional digital clock = lame. Other clocks only have this lame mode, so beware!

My girlfriend immediately (well, pretty quickly) picked up the binary system with this clock and now is eager to tell me the time, saying aloud "1, 2, 4, 8, 16... 16 + 2 + 1... it's 19 after the hour!" Very cute :)
