This chapter contained two hopefully simple projects that allowed you to blow the dust off or enhance your soldering and desoldering skills. These skills will come in handy in the chapters to follow. We built two inexpensive but useful projects. All for about $5.00 per project, depending on how much the LEDs cost you.
Use your imagination. How about blue LEDs and wearing the lamp on your chest or head for Halloween?
In the next few chapters, your soldering and construction skills will be challenged even further, as we build a motion sensor out of a piece of a water pipe and a flashing infrared beacon. So read on.
