 Directions Lacking August 12, 2009
Eric
I'm an electrical engineer, my girlfriend is a librarian. She wanted to know more about what I do, so I bought this Alarm clock kit and a digital dice kit (http://www.amazon.com/gp/product/B001234Y6A/ref=cm_cr_rev_prod_title Pocket Dice (Kit Requires Soldering Assembly) # K-28). I recommend the dice over the alarm clock.
The assembly directions were barely adequate - they are in several languages and about half a sentence for each step. However, she was able to piece it together. We still have no idea how to set the time, other than to wait until noon or midnight to put in the batteries. There is no schematic provided, so it was impossible for me to help or for her to learn how it works. The actual soldering itself is reasonably easy, and good for a beginner.
In summary, this kit is only good for practicing soldering - you will not learn any electronics and you will not gain a useful alarm clock.
 Fun to build February 26, 2009

This was a project for my 14 yr old son to build on a cold winter day. The instructions were step by step so the assembly was a breeze. They did short change us one L.E.D that was easily found at Digi Key. As far as the clock goes the procedure on adjusting the time is not clear so changing it is a pain in the neck. All in all it was fun for my son to do. If you have someone who is just getting into electronics it is a good buy.
