How To Hack Together An Adjustable, Dark Activated, AC Outlet Powered, Cold Cathode Tube, Night Light
Step 1: Gather Parts and Accessories
Rummage through your junk box/drawer/closet/basement and find a suitable AC adapter. We'll go into how to pick the right adapter a little later.
Also in said junk, find a transistor, a potentiometer, resistors, and a photoresistor. Don't get too caught up in the values, I have a feeling we'll be replacing these with Radio Shack parts soon anyway.
