Evil Mad Scientist Laboratories sells two of the coolest soldering kits around. They are huge discrete versions of the popular 555 timer chip and LM741 Op-Amp (operational amplifier.)
These kits are just amazing. Detailed, fun to build, and look great on your bench or desk. Over on baldengineer.com I made a full review of the XL741. Same comments could apply to the Three-Fives as well.

While not the same as the full tutorial, think of this as a step-by-step how-to build a kit tutorial.
