content: At least he's showing what really can happen compared to just theoretical discussion or looking for the often rare accident video. How safe it is for him depends on how well he knows what he's doing. In the ESD, those kV discharges are typically very low amps, like getting zapped by an electric flyswatter or piezo lighter. The caps explosion is done by reversing the polarized leads, and the large cap discharge is a full short using 40V, as he says, but the spark is from the very high instantaneous current on the short.

content: Quote from: saturation on January 08, 2013, 03:48:53 pmIm wondering how much charge (and voltage) can a piezo lighter source. I got a quite big one (to light stoves) and i can tell you that hurts (!) when it zaps me!

content: An ESD gun is only simulating a discharge from a person. It if were lethal then there would be people dying of electrostatic discharges. The energy is limited because it comes from a 150 pF capacitor with a series limiting resistor so it should be safe just unpleasant. I doubt that much consumer electronics will tolerate a 25 kV discharge without damage though. Phones are meant to survive 8 kV air gap discharge

content: Great videos. Much better than a theoretical lecture of what might could maybe happen.

content: I think he's deliberately overreacting a little, in the ESD one e.g. I can see it spark for 2-3 times before he reacts. Usually static shocks cause an instantaneous reaction.The distance is also a little high for the voltage, looks like >10mm to me implying it's >30kV. Or maybe his atmosphere has slightly lower dielectric strength than the norm...

content: well the cap and phone call that I thought was because he added the irony of it being a wrong number, the chances of him having the accident and it being a wrong number were near nil
