Figure 6-17 Incubator Control Circuit – Schematic
REPEAT WARNING: Do not use an unregulated 9 V wall-mount power supply for this
activity. Use a fresh 9 V battery (this activity will drain the battery). The resistor will
reach temperatures high enough to melt soft plastic. Use care when constructing the
incubator circuit. Do not allow the test tube to touch the resistor directly; even so, it
may warp. NEVER LEAVE POWERED CIRCUITS UNATTENDED!
