Be sure to heed all the safety precautions about soldering that we give
you in Chapter 2. For example, don’t leave your soldering iron on and
unattended. And just in case a bit of solder has an air pocket and pops,
wear your safety glasses!
Coaxing the coil ..................................................................................
Take your ferrite rod, 26 gauge enamel-coated wire, some electrical tape, and
glue and get ready to make the coil by following these steps:
- Wrap electrical tape around the ferrite rod.
This protects the enamel coating on the wire from the ridges that run
along the rod.
- Cut two small pieces of electrical tape, about^1 ⁄ 4 " wide, and place them
in a handy spot.
