I am an electrician by trade...so i thought the avatar fitting....
I did this as a young child myself...
Now the Ontario Electrical Safety Authority requires tamper resistant rec. installed in all new home construction...
The new recepticals will stop any child from shoving a paperclip into one side of the outlet...
But if the child is smart and unbends the paperclip it can be inserted both sides at once...
Protects the stupid kids i guess....

two early attempts at self electrocution were the one i reported earlier, the
second was really cool

i found an old inner race and tapered roller brgs in a junk pile, tore apart the cage
and had this nice looking roller about the size of my 9 yo thumb, it had that dull inner
layer and the shiney outer layer

i wondered if it could be charged like a battery?

:)

so i unscrewed the bulb from my desk lamp, carefully place my roller in the socket
and plugged in the lamp cord to the wall receptical

:o

hmmmm, that didn't work out very well!

ruined my desklamp too!

no better lessons learned than those from direct observation

I was about that same age as the kid in the avatar when I used the ends of an electric cord plugged into the receptacle to rub together to make the nice pretty sparks. Looking back, I probably should taken that as a hint to stay away from electricity.

WIZARD !!!!! I did the same naked neon bulb (sans-resistor) trick.  Mine made a pretty white light but only for a second.  There was a slight 'bang' noise and smoke coming from the wire burn marks on my fingers.   :o

Used to cook hotdogs between two nails driven thru a board.  Each nail was hooked to a wire of a two prong cord...  Nothing like a dog, with relish, onions and ozone:)

yes, we are raising a generation of over protected wimps...

There was actually a version of that on the market. It was something like the george forman grill except for the spikes you put the hot dogs on. It had a switch under the lid that cut off the power when you raised the lid. The switch on mine stuck in the on position. WOW

We had a"Hot Dogger" when I was a kid..... It had 2 rows of metal spikes that you pushed the ends of the hot dogs on... when you closed the lid it electrocuted them!

And I thought that I was the only one that remembered one of those weird hot doggers.  You know they might even have caught on it it hadn't been  for the microwave oven becoming affordable.
I think Ronmar is right, the whole world is raising a bunch of wimps.
Gotta be a man to eat an electrocuted dog!

Dunno, but I had a chemistry prof who said his dorm was wired with DC, and when he tried it (with a board, a couple of nails and a wire), the dogs tasted even worse -- one end was soapy and the other very acidic!

This was your professor and he lived in the dorm? And he thought it was wired with DC? Did you ever think of checking into the accreditation of that school? LOL

i remember back in grade school, jr and sr high school being called upon lots of times for electrical issues
everything from soldering speaker wires, to my favorite pulling a broken prong from a plug in out of a wall socket.

funny how the kids and teachers would look at me in awe wondering how i could just grab it and pull it out with my bare
fingers and not get shocked.

geesh, it ain't like i was standing in a puddle of water or something!

i guess learning about completing a circuit with a bobbie pin at 2 was a good education, one would think that would have been
enough to make a kid go into a completely different line of interest, like pottery or glee club

The A/V Club was a group of students who would meet after school and learn/play with the schools audio visual equipment in order to learn how to set up and operate it.  It was the sort of club that would attract tech heads.  Our reward besides the learning experience was to be called out of class during school hours to go run a piece of A/V gear at the request of a teacher for their class.  We got to see more movies this way which helped break up the boredom factor that brighter but unmotivated kids like me often had with school.

Hey!

I did that in school, too. I did it for five years. As part of being the head AV nerd, I ended up doing it for all the high schools in the board - there were 5. And - I oversaw the setup of all the bands that played at all the High School dances. Which led to working directly with the bands at their non-high-school gigs for cash. Which led me to joining PACTRA, and becoming a roadie, sound and light man. And I worked with bands like Rush, Fludd, Triumph, Max Webster, Lee Aaron (look her up, she fine!), Lighthouse, The James Gang, Crowbar, Goddo - basically anybody who was an up-and-coming Canadian band in the seventies. Those names might not mean much if you're not a Canuck...
The groupies might not have been able to get too close to the band, but in those days, the sound/light guy sat out at the board in the crowd... good gig for a geek...

Oh, and I got to work on all those "Smile" Labatt Blue Beer commercials as a prop tech.

Oh ya, worked at Stratford as a lighting tech for a summer, too.

For years, when I took holidays from my real job, I'd go on the road with a band for a bit. It was a blast. I did my last gig in 1984, but I still call some of those guys - and girls - friends.

So - the "nerd" thing worked out pretty good for me...

Now - back to your regularly scheduled Icy Ball discussion. ;D

They didn't call it the AV club when I was running the projector...... it was- "git that redneck dumba-- in here to run that projector before he gits in trouble agin".
No I didn't get to meet any cool people either :'(

Well you obviously took that opportunity wayyyy too far!  ;D  Great story!  So I would be addressing a person who knows what an Altec A-7 VOT speaker is.  Lots of the bar bands used to use 'em for PA.  I absolutely love the sound of those outdoors!  I have four A7's, set atop four 816A bass cabs here in my shop.  8)
Title: Re: Icy Ball
Post by: cognos on June 15, 2010, 02:47:22 PM
Oh ya. A7's, and the A6 bass bins. Nice stuff. My right ear is burned out from setting those things up in bars... pro stuff had tweeters that looked like truck grills, probably cranked 150 db, so high you couldn't tell it was frying yer brain along with  yer ears...

I made a lot of PA bins for bands. 1" or 3/4' ply, grey mouse fur carpet, steel corners, pointy feet to mass-couple them to the stage. Put Phillips composite drivers in 'em, wound the crossovers myself. Bulletproof. Those were the days, wish I still had some.

Always hated Bose systems. Light, small, and loud, but baaad. You'd set up in an empty bar/hall/etc, then you'd have to reset every time somebody entered the room or moved a chair... ;D Of course, the band would blame the sound man...

I run 2 Klipsch LaScalas and a set of Tangent RS6's in the house. Yamaha A1 Rack-mount amp, T1 Tuner, TC800GL Pro tape deck, and an old Scully 4 track mixer... the sound is frightening to the uninitiated... several turntables... and many albums that I wish I had gotten signed by the people that handed them to me...

Even with bad ears, I win bets with people by telling them which music has been downloaded from the internet, vs. being dumped off a CD... internet music sounds "sharp" to me... never mind my collection recorded from analog albums and digitized...

I must have 1000 albums. Many only ever played once or twice to record them to cassette or digital tape. All from the 70's and 80's.

Kids don't even know what good sound is. Think an Ipod dock sounds good... ;D

Hey, I'm a Luddite.  ;D Hence the attraction to Icy Balls.
