Re: [AMRadio] More electricity
Can't let this thread stop. My son had a friend who would connect IC' s to 110V at their electronics class, The IC's would break open and fire would shoot out. A few years later the friend visited my son and they decided to go to the class and say hello to the instructor. He gave them a horrified look and started to quickly thumb though the attendance records. He was quite relieved when his friend said they were just back for a visit, and were not taking the class again. I had a Tesla coil that used 4 810's in parallel as the oscillator and was powered with a 2 kV power supply. I had plenty of trouble with the primary arcing to the secondary, which caught the insulation on fire. It was necessary to turn it off and blow out the fire. I finally solved it by using a gallon glass apple juice jug, wrapping a string soaked with gasoline around each end and setting the string on fire. After a number of tries, I had a glass cylinder, which I put between the primary and secondary. I took it to high school, set it up in the physics lab. and turned it on. An arc jumped to the wood window frame, catching the wood on fire. We turned off the coil, blew out the fire, cleaned the frame, and discovered a nail under the paint. Fortunately, the faculty didn't notice the damage. Later the instructor came by and asked if anybody could be shocked. I said you had to be careful, and discharged the 4ufF filter cap with a screwdriver, which sounded like a pistol shot. At his request, I took it home later that day. My son worked as an assistant in the computer lab, helping students with their problems. A big, husky kid couldn't get the computer working ok, and my son pointed out that the student needed to put the 5 1/4 floppy in the drive first. The student tried, missed the slot, and the floppy was wadded up like a piece of newspaper. 73's Jim w6ivw __ AMRadio mailing list List Rules (must read!): http://w5ami.net/amradiofaq.html List Home: http://mailman.qth.net/mailman/listinfo/amradio Partner Website: http://www.amfone.net Help: http://mailman.qth.net/mmfaq.html Post: mailto:AMRadio@mailman.qth.net To unsubscribe, send an email to [EMAIL PROTECTED] with the word unsubscribe in the message body.
Re: [AMRadio] More electricity
Did you practice this exercise just before a test? :-} - Original Message - From: D. Chester [EMAIL PROTECTED] To: amradio@mailman.qth.net Sent: Friday, March 30, 2007 10:27 PM Subject: [AMRadio] More electricity In high school we used to play a variation of chicken using a telephone magneto. Several people would join hands in a circle, except for two who would each grab one hand onto a wire attached to one of the terminals of the magneto. Then an assistant would start cranking the magneto - slowly at first, then faster and faster until someone let go. The first person to let go was the chicken. That person would drop out, and the rest of the group would reassemble and try again, and again, each time eliminating one person. The last person remaining was the winner.

RE: [AMRadio] More electricity
Nope, you're sure not. My Radio Electronics instructor tired of people fiddling with things on his desk in the lab and set a charged can capacitor on it. It wasn't long before we heard the yelp and then the laughter from Mr. Cannon! No! It wasn't me. Of course, that was the early 60's, you'd get sued for such fun nowadays! Reminds me of another incident when I was in high school. Used to have a neighbourhood kid would come over to the house and pester me. I had to tolerate him because his mother and my mother were good friends and co-workers. He would fiddle with stuff on my workbench, and he loved to pick up my roll of solder and chew on the end of the wire. I suppose lead poisoning takes a long time to show any noticeable effect. It finally occurred to me a way to cure him of the problem. One day when I saw him coming, I quietly substituted a roll of acid core solder for my normal roll of rosin core. Sure enough, it wasn't long until he picked it up and put the end of the wire in his mouth. I don't have to explain what happened next. I told him that I had switched to a new brand of solder, and from now on it would always be like that because that brand worked much better than my old solder. Needless to say, he never chewed on my solder again.

Funny, we used to do the same thing in our electronic shop at S.U.N.A.V.T.S. Mod-U-Lator, Mike(y) W3SLK When I was in High School Voc.Tech. in the late 60's we used to charge up a good axial H.V. electrolytic with the leads wrapped around the ends and say catch, to an unspecting classmate. We also did the,... hold on to two can lytics with the cans connected to the cap tester, a big CDE, and see how high the leakage test voltage would get before letting go.

Seems this was something of a very wide practice.
