Worst Tech mistake you have ever made?

[MilkJugg24]

How would that kill you?

 

Sorry forgot to mention that the resistor wasn't rated for that high of voltage, so it got fried, then opened up 36 amps of current. You only need 0.2 amp to kill you.

That's not how electricity works. The current flowing in the circuit won't just flow into your body, your body follows the laws of electricity as well, and has a very high resistance.

Well yes, it doesn't jump that easily at all. But I was implying if I would have touched it, and if it conducted, sending that much current straight through my right side into the ground since my left arm was behind my back, would probably have made toast.

No. It wouldn't. Your body is a 100 kilo ohm resistor. What is the current through a 100,000 ohm resistor with a 36 volt supply? 36/100,000=0.36 milli-amps, which is below the threshold for "feel-able" shocks.

 How though?  The resistance of the human body is very high; even ideal conditions ( wetted [high salt liquid] metal rods in hand, with one connected to the source one grounded ) would get nothing like .2A with a force of only 36.1 volts .

Say the resistance of the human body with wet skin is in the 1000Ω region V=IR I=V/R or 36.1/1000 = .0361A(mps) hardly lethal .

With dry skin it is in the 100,000Ω range so current would be .000361A .

 

There's a reason they use 2000 V(olts) in Electric chair executions.

Thank you for better phrasing what I was trying to say. People who don't get physics acting like they're electrical engineers annoys me.

I would do that, buy my case doesn't allow me to do it.

Accidentally taking out an HDD from an £800 laptop without even realizing it. The battery was somehow giving out current whilst it was off for some reason. I have learned from my mistakes, but with difficulty...

No intake/exhaust fans, no 2.5" slots, no USB 3.0 etc. etc.

 

I thought it was really good because it was 3GHz -.-

 

This was 3 years ago

 

Lucky that I built my current epic PC to use cus I couldn't have lasted much longer on that with 25FPS on league of legends at medium settings.

[trag1c]

Yeah but you touch it and the current that flows through /you/ is going to be much smaller. The lowest resistance your body is likely to have (given wet skin, or a cut) is 1000 ohms, giving a current of 0.036, which wouldn't kill you. In most scenarios, your resistance would be more like 100,000 ohms, giving a negligible current.

Of course but that's why I said absolute best circumstances which would probably directly touching the heart. Its possible but not feasible.

what? So your laptop battery screws in? Most or every laptop you need to unscrew something to take the hdd out

[HrutkayMods]

When I started experimenting on modifying and upgrading PCs when I was around 9ish? I had my first personal PC (a Pentium MMX Pionex tower) apart and wondered what would happen if I flipped the red volt switch on the power supply from 115V to 230V (because bigger must mean better right?). Plugged it in and POW!!! Sparks, flames and smoke came rolling out the back of the power supply. Oops

[CandyCaneMan]

Had an amd processor but wanted to upgrade to intel, budget was tight so I went for a fx-8350 because I already had a AMD mobo after the cpu got delivered to my door and I sat around for few weeks I remebered to look what cpu's the motherboard support ofc the 8350 wasn't one of them so I had to buy a new mobo, well shoot.

[Brennan Price]

Oh no, not like that. I was in the process of diagnosing stuff with the HDD. However, the battery was giving out current without me realising so when I was taking out the battery, it screwed up.

Buying AMD cpu.

while building my first ever water loop, I lost the O ring in my D5 pump. Worse however, is that I didn't notice until I fired up the loop, filled with water. EVERYWHERE. THE WATER. WENT. EVERYWHERE. Nothing will make a techie move faster than watching water fly into your GTX780.

It was the worst... I didn't even know what was wrong, so it happened twice in a row (after WRENCHING the pump on and it still leaking)

WD MYNET 900c nas/router. strage never worked on it, and router worked about  as as a router made of swiss cheese.  Also I've RAZER kraken pro, about as good headphones as a headset made of muenster cheese.

That Phenom II x4 is still a very capable CPU and has aged well, mind if I ask what your Intel counterpart would have been at the time you built your system?

Took the pump of my Revo D5 to see what it's like and they are difficult to reattach. thankfully this was before it was installed and hasn't spewed...yet
