Indeed. In the earlier days of me being licensed, my HF rig zapped me a few times due to problematic grounding issues. Seemed to have the most problems on 75m and 10m. On Tuesday, October 29, 2019 at 6:30:01 PM UTC-4, Terry Bowman wrote: > > > RF burns are the worst. Tesla put thimbles on his

The following is not in any way advice; This is what I have heard; The heart can be stopped by a few mA at 9V. Applying that to the skin will not get it to the heart because the skin is a good insulator. You need enough voltage to break down that resistance, or there needs to be a physical

I’m very reckless when it comes to my Nixie projects. I’ve shocked myself with 150 - 170V DC more times than I care to admit, and every time I’ve done it, the shock isn’t that bad. However, every time I’ve done it, my hands have been dry, and there’s been a series resistor somewhere in the
