The kit versions of the microTimer and microAlt come with all necessary components and complete documentation on CD. The PDF format manual provides high resolution images for assistance during assembly and allows one to print a hardcopy for later reference. A tutorial on the assembly of surface mount components with standard soldering tools is also included. Your soldering iron must have a small, clean tip and your eyesight must be good to successfully complete the kits. The majority of the components measure about 2mm long by 1.2mm wide. These are not beginner projects! If you are in doubt as to your abilities, start with the timer kit before attempting the altimeter.
