What are you waiting for? Yourself to get a sense of humor?


Or the rod to fall out of your ass?

[Porsche-poor]

Up past your bed time? Getting a little cranky there.

[porsche4life]

I was joking with you, you are the one that got all defensive and told me to go back to my rock....

So Old man? Past your bed time?

[Porsche-poor]

Nope not yet? Some joke just a tad to personal I think.

My son got ahold of my camera tonight. OK, not a big deal; he took a few photos. So I plugged the camera into the computer just now to download the pics from today. WTF? How are there 137 photos to go? I thought Mrs. Noah took only 15 or 20 at a baby shower she threw today.

Amongst other random stuff, looks like little Noah took pictures of one of his Lego story books. Page by page, paragraph by paragraph, photo by photo. It's like a homemade Kindle.

Bat chit crazy ........every last one of y'all tweeze......and yet us guys are stupid enough to keep coming back for more...

[Porsche-poor]

My oldest did that to his mom making a stop motion lego movie. He filled the camera up and didn't bother to tell anyone.

[tweezers74]

My son took about 100 pics of all his fake bugs... Close up on my phone. Scared the crap out of me when I opened my phone up and there is a huge head of a praying mantis staring at you. I love kids.

He just kept going and going. That was the last time I have been hit by one of those.

Ouch Dave.

Fortunately most of that HV stuff is low current or most of us would be gone by now

Been hit by the high current stuff a few times (PSU's, telecom switching systems, Radar stuff). One of the worst was a 50VDC system. I was working with my arm between two close vertical racks with a cro probe. The system was ancient, with exposed conductors all over both sides of the racks. The back of my hand brushed something live and it bit, my reaction was to jolt my hand forward into the rack in front of it. Got bit again. The reaction then was to jolt back in the reverse direction, ouch again, and so on, and so on. It went on like that for a few cycles before I was able to pull my arm free of it.

It was the same bastard radar that bit me with the 850V pulses. I also managed to get a 10KW RF burn on my hand off the bugger one day, and numerous reading on my radiation badge over the many years I worked on it- It had a huge klystron as it's output amplifier.

Night all. Yes its bed time have to get up early and head to the airport. Must set a good example for the kids and hit the hay.

I'll check in when I can..........or maybe not.

[Outback Porsche]

Enjoy your holiday, night David

Kids are cute. I'm enjoying this grand parenting thing, get to do it all over again without the crappy stuff

[slodave]

Have a safe trip down, Dave. See you in a few days.

Good times, Jeff.

Electricity is fun. I enjoy playing with it and even like the occasional shock. I still want to build another Van de Graaff generator. Tesla coil would be fun as well.

Yep, hasn't stopped me. It still pays the bills

Jacob's laders are cool too.

OK, now you guys are talking serious stuff. Odd that this subject came up as tonight half the Formula Electric team (half = about 4 people) was nearly killed while I was helping to take the batteries out which are sort of interlinked by these dam ridges on their sides which makes them get wedged into every position but the one they are supposed to be in. We had to lift the whole battery pack as a whole therefore and almost shorted it to the tube frame. I was stading on the million pound steel table and holding on to/ leaning on the steel tube frame. I was holding one side of the battery pack with nylon straps going beneath each row of brick-like batteries. My end came up, the other guy did not get his end high enough and the whole thing tilted. It was scary for a minute there. A case of "hold on" and not being able to do anything else. Luckily they are only about 160 pounds I think. Not all that hard to hold.

The motors I think are a total of 100hp or more. And I heard 700 amps being discussed. Not sure what the voltage is but there must be about 24 bricks, and I do not know how many cells are in each brick.

[slodave]

Probably 12-24V, Max. You need amp hours, not voltage. Probably wired in parallel.

[Flieger]

Well, there is a "High Voltage" area and a "Low Voltage" area. HV needs the big orange cables and lots of coverings, fireproofing, crash proofing, etc. So I don't know if High Voltage just means High Power.

[slodave]

It's the amps the usually kill ya, but when do you ever see "High Amperage" stickers.

Not saying that there isn't some conversion going on with some HV caps in the system.
