DIY toolbox – Non contact voltage tester
One of the skills I’ve learned since buying our house is electrical work. Messing with your electrical can be very intimidating, but any good home improvement book will teach you the basics. The easiest changes are replacing light fixtures, switches, and outlets, but even adding additional lighting and outlets is pretty easy when you have opened up a wall to replace sheetrock or add insulation.

Nice post. I agree with you John, electrical works can be quite intimidating.
