STEP 3: 120V Applicator Wiring Actually the first applicator I built was the 120 volt applicator. I got all of the basic electrical parts for the project out of my salvaged parts drawer. The 120 volt negative ion generator came from Electronic Goldmine, www.goldmine-elec.com. If you choose to build the high-voltage version of the applicator, make sure you are experienced with 120 volt AC (household) wiring, since any wiring mistakes can be deadly. If you are an old hand at house wiring and know what you’re doing, then go ahead and give this version a try. If this doesn’t sound like you, I strongly urge you to build one of the lowvoltage alternatives instead. I can say the version of the 120V applicator I built is safe. However, because I cannot verify the skill level and attention to detail of those who choose to build this project, I assume no responsibility for any injury or loss associated with building and using the 120 volt applicator. All of the small parts needed to wire the project are available from online vendors (see the list), your local electrical/electronic retailer, or perhaps from your own parts drawer, figure 3.1.
