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.
