Why I am not a big physics fan...
« on: February 15, 2018, 10:01:09 AM »
Dear Alembicians,

I thought I would share with you a brief, and now  in hindsight, humorous, encounter involving electricity from a few weeks back.  I was reminded of this entertaining 20 minutes in my living-room by the "ElectroBOOM" channel reappearing in my Youtube feed, today.  The probably unfunny story goes where I was switching amps to use a small Behringer practice amp to show the cats something (the only one connected to speakers, presently; it's cheap, not the best, but cheap and not loud enough to bother the neighbor).  I bent down to plug into the instrument input jack when I brushed the adjacent gas heater's iron chassis with my upper arm while still holding the metal chassis of the plug.

Now, I understand some folks may think I regularly suffer from certain forms of paralysis, but that's generally under the influence of benzocaine, general anesthesia/whipped cream, wings and beer, or the approximately 20+ volts and very few amps that ran from the illicitly shorted heater chassis through my trunk and into my amp (my bass was not yet connected, mercifully).  This bit of fun yielding a combination of an inverted shimmy and some pro-am mambo warm-ups, while I managed to slur out "gna$h-ho", as in rhymes with "lasso", thinking of our property management before breaking the connection.  Mercifully, my wife was not looking, the occurrence didn't last long, I could pass it off, and calmly explain the occurrents (BAD) without either smelling like pot-roast, or twitching any more than is normal.

After the twitching and ache in my arms stopped, there have been no further problems, so no harm, no foul, no problems, and this is a cry for bupkis.  I later half-jokingly said to the Mrs. that we should talk to the landlord after we can appropriately document/measure this chassis grounding problem, as I didn't enjoy pretending I was Bob Weir onstage at Wookstock (I am guessing an electrical ignitor is poorly grounded in the gas heater's exterior, but load is load regardless of origin).  That quip did not, unfortunately, register, nor did suggesting that she should try the veal and that I would be back next week seem to provide banal entertainment.  She seems to enjoy classical music more, so if/when I get rheumatic fever, I can make all the lame "Amadeus" jokes I want, and then she might laugh.  Might.

I guess, at least, I can say that some of you folks are rooting that the Behringer is totally or mostly dead due to the short, and "ha ha".  When I get my new multimeter, I can let you know.  I'm a touch wary of plugging in anything to see if the amplifier works, or risk another short and some potential burning during use.  Besides, it's hard to wear the lobster claw oven/safety mitts and wield an instrument, probe, or soldering iron at the same time.

Safety first.

Oh, for all who like to watch physical comedy, here's ElectroBOOM's channel (https://www.youtube.com/user/msadaghd), and some of his greatest hits ( I believe he is a part-time comedian, and full-time Canadian, who is a professional electrical engineer/physicist who does his demonstrations safely to entertain people like me, who leave this to the professionals.

Again, everything is fine, I am not trolling or cruising for anything from anyone here.  I just thought that this is just a now funny mishap that involved me, the only person I can laugh at pointedly without being deemed worse and more offensive than Golden Corral. 

Dang it.  Now it's back to square one with that.  That's a shocker.  Regardless, please pardon the typos.

ooooph...Glad you're OK


(I'm going to borrow 'occurrents')


My amp tech and I were surprised to see 80 volts on the heat sink in an
Ashdown EBM 500. I'm surprised we  didn't get bit. After a phone call,
he verified it was part of the design.


I often think of (and bow down to ) the helicopter line repair personnel that become part of the circuit while repairing the high voltage wires that traverse the country. My Grandpa lost his life
as a pole lineman while working in a storm. I never met him.


'Being grounded' isn't always the way to be ???


Thanks for the insights,
Let's hope your cats were entertained  :o


Elwood

I am reminded -perhaps inappropriately- of a story I once heard about a bad experience involving an electric fence and a lawn mower.   ::)   I'll have to look for that...

I'm also reminded of Forest. (ed_zeppelin)

No worries, sir.  The post was just meant to be mildly amusing because it is now two to three weeks on, so its now funny to me, and it's the second time in this domicile I've had to be the ground for an electrical fixture/or appliance (well, third, I touched the light outside, twice, in a rainstorm, to make sure that it was actually ungrounded; I am a real smrt fellow...GHNNNNNN!).  And it involved the potential destruction of a little Behringer bass amp that some folks here have a valid opinion that regards its quality and robustness, much like a Ford Pinto.  No problems, no trouble, just trying to find the bright side in this case. 

I was just mostly surprised that the better half doesn't find any of this funny, as I am fortunate that nothing came of it, despite the potential loss of a 45W paperweight.  It was not anything like the ballsy folks who did or do communications or electrical work, or do industrial fishing, contracting, trucking, soldiering, etc. for a living.  This was just a piquant electromotive tickle with low current and maybe double the voltage of a car battery to remind me I am behind my resolution to get more exercise so I can look like Schwarzenegger by 2019.  No worries, Elwood, but I appreciate your concern, and I am sorry if I cut too close to the circumstance that unfortunately befell your Grandfather, and I am sorry that it happened.

But I am glad that you responded as I thought I had really gaffed here, and I hope I have not, because no one was laughing at my invitation to do so at my blunder, all while I was chuckling hard as I wrote the post.  But all in all, the cats did have a good time.  Jerks.

edwardofhuncote, I hope I did not offend you as it was not my intent.  Moreover, I hope that in saying this, you are not offended further: you comment reminded me of this batch of shenanigans_https://www.youtube.com/watch?v=_T9qiGCq5sk.  This was brought to my attention about 10-15 years ago by a gentleman who looked like the subject in the video, and who had gotten the video link via email.

Your good, keep 'em coming.
I'm always proud when I can recall my grandpa's  service in the history
of electrical networks. So I say Thanks ! :)


I bet I can speak for Ed of H (this one time);
"No offence;D


cheers

Never been offended by anyone here. To tell the truth, I really find this little place to be the least offensive place on the whole www. Just last night I met another Club Member (who happened to ne passing through this way) for a cup of coffee and an Alembic mini-meet-up. We're all buds here.   :)

I was serious though, your post reminded me of a guy that used to hang out here... he's been MIA for over a year now.  He may well be reading along and enjoying for all we know.   ;D

Then, better than quipping about equipment, may "To Forest: a salutation of libations to an Alembician.  Slainte." be more appropos.

Wherever Forest might be, I hope he is well.  Cheers.

Anyone who fooled around with tube amps in their ignorant youth as I did knows what 400 volts tastes like. It was kind of a regular occurrents (hah!) until I really decided to pay attention. One hand behind the back when playing inside a tube amp! Drain the filter caps! And always makes sure the d*mn thing is unplugged!

Beware the old Fenders with the death cap. A guitar player I played with back in the day experienced what happens when the cap goes bad and the stage power is on a different leg from the PA. She couldn't even talk for 45 minutes. For older folks like us, it can be deadly.

Edwin,

As a tube amp fan, I will absolutely take that into consideration and double glove with thick tattooist nitrile gloves if I have to touch the guts of my amps.

By the way, have you guys seen many Lichtenberg Figures on guitars or basses ( https://imgur.com/gallery/umc8991;http://78.media.tumblr.com/cb42ec04d2fa31091d3986323c3dec0d/tumblr_nt7hpzdPgS1uqb2rpo1_1280.jpg; https://warosu.org/diy/thread/955137)? To anyone's knowledge, has Alembic ever done this to figure certain rare instruments? 

It is rather pretty and exciting wood art but I kind of cringe a bit while watching these videos, wishing these guys would wear closed toe shoes in the name of safety.  But, as I have no desire to play with a microwave transformer, I am not going to go near this, and they are more intrepid than I, so who am I to nitpick?  Bob's their Uncle!

Cheers.

 People are crazy, (did I say that out loud?)  :-X


This video haunts me. Imagine the mistakes that must have occurred
while dialing in the process.

Elwood,

Have you read of J.B.S. Haldane and the primeval world of biomolecule self-assembly, the RNA world, its transition to the DNA/protein world, and evolution into single celled prokaryotes and eukaryotes, etc.?  Truly, High Voltage Rock and Roll.  Cheers.

Best regards,
