Hey guys First post here just joined up because I don’t think I can go any further in electronics until I deal with this... or discover this is normal and I’m testing wrong.
I got a scope recently and have been playing...ah experimenting with it. Something I wanted to do was connect up my electric guitar and see how the wave looks for different notes. As the hairs on my arm brushed against the strings I got a little shock. Just like I always get when my arm touches the metal case of my phone when it’s charging and when my laptop touches the hairs on my stomach. Knowing that my guitar was grounded through the scope something clicked in to place, anything that’s grounded is giving me a shock, but if there grounded then I’m giving them an electric shock, and everything I touch, all the sensitive electronics I touch, the boards and chips that seem To not work when AlI I have done is take them out of the ESD bag must also be getting a jangle off me. If it was static from the cheap nasty pink carpet that came free with the house then why is it constant.
probe in mouth time. I’m getting around 10Vac @50hz (I’m in the Uk so mains is 230rms @50hz). I’m live at 10v... not a chance, Clearly I don’t know how to use a scope. But I definitely know how to use a multimeter... ok I’m live. But surely there’s no current there. Turns out I can run an LED just by licking my fingers and holding one leg against earth it’s dim but it’s definitely lit.
So I probe my mouth on Chanel 1 and the mains on channel 2 see how they compare. The 50hz in my mouth seems to be leading the 50hz mains so I think it’s an induced voltage it seems to vary depending on where I am. My carpet is horrible but not at all conductive. I’m lost, where’s it coming from? how do I get rid of it? Do I need to get rid of it? Health risk? Superpowers? I was hoping for X-ray vision or flight but I guess volt man could work people need LEDs testing right
