preventing sparking with high voltage

[ncalenda]

good info, I had went to radio shack just to look and did see them there. I will use this info when I go back to buy one. I had no idea they sold them, I was there for another item.

One question, is the spark harmful? When I saw how to get rid of the spark I thought it would be worth it to get rid of it. It just seems as if it could cause damage.
