Your most lethal component in your work room

So today I recieved my huge capacitor, 10,000UF @ 450VDC, this thing is freaking huge. I mean it's like I'm overcompensating for something... Anyways, what is the most dangerous component you own? This is probably it, as it has enough power to remove limbs. Heres a picture too.

Ahh he is a chip off the old block. Everything must be connected, everything must be hooked up and everything must have extra lights and be turned on. Sniff....so alike, and also so dangerous. I once came down to my basement workshop, and he had inserted about 20 LEDs into the power rails of my breadboard and was then asking how to power it up. Another time, I had stripped down an old RC car to get a picaxe brain, I found him cutting all the motor wires, telling me he was fixing it. :-) funny now, not then. By the way..how unreal is it that the capacitor doesn't have a warning on it.

I'd say that I am the most dangerous thing in my workshop, since accidents tend to happen when I get lazy, sloppy, or simply temporarily stupid.

I once foolishly ran a thin board through my table saw in such a way that the piece got pinched between the blade and the fence. A scrap came shooting back and me and hit me in the chest hard enough to cut skin through my shirt. I came away lucky and with a new held respect for using my saw properly.

Last year I took wood shop in school and do do anything we had to pass a safety course and one of the things was to never stand behind the blade.

That's sound advice, and absolutely true. 

Working with a thin piece on the table saw as I was, I drifted into line with the blade. I was at least smart enough to use a push stick. ; j

Anyway, it was a lesson I won't forget!

I say watch out for those clipped leads from like LEDs. I was brushing them off my table once when I brushed one into an edge it went straight through the bottom of my finger and out the top near my nail. That was my only major thing and it was not major. Not too much pain since it was thin, but it looked cool.

The most dangerous thing in my workshop is firstly my dremmel and secondly my soldering iron .

When I was sanding a board a piece of the board broke and if I haven't moved fast enough at the moment I would have only one eye.

I was using my dremmel..

Oh man...If my vote isn't for me, then it would probably be my knife.


Years back I was trying to drill a hole in a brushed aluminum light switch cover without clamping it down...just good old fingers holding it down to the bench.  The drill caught and spun it around taking the whole outside of my thumb with it.  It was pretty gnarly.  Nothing like showing up in the ER when my mom is working (she's the triage nurse) with a blood soaked towel wrapped around my thumb...hahaha.

When I was in High School, (mid 60's) I was working on a 4,000 watt PEP linear amplifier, (RF). I was taking some measurements on the plate supply, (3,000VDC), I went to adjust the meter and got between the plate and chasis. I woke up 10' away with 3 veins punctured in my right arm where it went in and 3 veins punctured in my left arm where it went out. That unmistakable smell of burning hair was everywhere and it was weeks before the pain in my arms went away and they started working right again.

Dude you are lucky that you can still write this. The current that hit you was probably high enough to kill you right on the spot.

I once got hit by 8000V AC but just a few microampere, so the hit was not that strong to injure me but it was a quite tingling experience :-)

25kV at 30mA, not fun. Flyback transformer.
