Neat project, however the instructions were lacking and no theory is taught. If you're picking this up as a beginner's learning project, you may want to consider another kit.

You really have to read the directions prior to beginning. Seriously. I ran into several issues. The directions are meager at best but will get you through if you take your time. They did fail to mention: 1. which battery is to be used (I used a CR927 which worked) 2. there are 2 electrolytic caps that come with the kit. directions only speak to one though the PCB does have silk screening for the second. 3. LOOK AT THE DIAGRAMS! I failed to do so and added the temp and photoresister to the board and not off of it like the diagram shows. The directions did not refer to the drawing so I missed this key step. My clock does not dim like it should and I'm not about to de-solder the tubes to redo it. Other than that, it's a neat little talking clock. Enjoy.
