This special kit is similar to the regular ?Learn To Solder Kit? (C6445) however this kit has some very unique features. Not only does it have a special nonfunctioning ?Learn To Solder? section it also has two additional kits on one circuit board. You get a bright yellow and red ?Jewel? LED Flasher Kit and also an Insanity type Alarm Kit. The deluxe learn to solder kit uses a specially designed circuit board that allows you to build all three kits. After construction and testing you simply snap the main circuit board into the 3 separate individual kits.
