Re: BS, was Re: [HP-Agilent-Keysight-equipment] Spread the word -- Swap Meet Returns!
¿ªÔÆÌåÓýRadu, ????????????? Totally agree. I have spent some time in what we will call heavy industry. It is one thing to know that a Tek 576 can light you up with 1500 Vdc and might kill you. It is QUITE another to stand next to a peace of equipment that will DEFFINATLY kill you and not even notice that you are in the way. Safety is key in any lab or industrial environment. Respect and caution is needed, abject terror can also be harmful. We don¡¯t need a full flame retardant hazmat suit to deal with an isopropyl alcohol spill. Though HR might want me to use one. ?I have run in to quite a few that won¡¯t take a failed power supply apart and even look at it ¡°because it plugs in to the wall¡± one of my goals is to empower people especially just starting out. Those first few successes are critical. But if one of the first projects is a CRO scope it is also good for some one to say hey don¡¯t touch the fat red wire. Weird stuff like insulation doesn¡¯t work so well at 21,000 Vdc ? It has been strange to watch the pendulum swing over the years in that respect. I have known a time when we still had silver thermometers. ? Zen From: [email protected] <[email protected]> On Behalf Of Radu Bogdan Dicher

(as I've known you as Zen over emails), ? Agewise, I'm probably right between you two, though?I'll wager far closer to Eric than Dave. Likely at least the same generation. I've been doing tubes for a good bit over 15 years, and repeatedly getting to taste the 450V of my amps' B+ hasn't ever deterred me. I started with electronics at about 7, and no one watched me much if at all at the club house when I was etching my boards with acid.? ? That said, I do want to suggest a certain amount of reserve with how we feel about the dangers of industry from certain times. I grew up in the most polluted place in Europe in the '80s (to substantiate, this orange acid rain was coming down most evenings around 6:30PM, so no one would ever be out for a couple of hours around that time, particularly in the fall, due to factory schedule of heavy chemicals waste release through unfiltered tall towers and atmospheric?conditions on this riverbed valley, and hanging clothes to dry was a lottery in terms of whether you'd be picking them black when dry due to other chemical agents being released in the air at other times, and for kms around this factory, up and down that same valley, the landscape was factually lunar as there was no growth on the bare, red, soil) and I can tell you living?with heavy metals around you, and inside you, does have effects on your body (and probably mind). I am saying this based upon my experience, and growth as a young boy. I am very careful with my kid around my bench.? ? Now, all this said, I want to make sure I thank you, Dave, for encouraging me on a certain project a while back (the younger hobbyist tackling a b..ch of a problem). I can't overstate how important this is, for folks from newbies to maybe some of the veterans. Some of these projects are not easy - if they were, no one would ask for help, and this forum would probably have little reason for being. I don't think we tend to have enough regard for encouraging the OP (sweating and swearing at their bench over a perplexing issue, and probably hating their project a bit at the point of asking for input), and making them feel as part of a community. THIS IS HUGE. I almost never capitalize, but here it's called for, and I am.? ? I am stating this to point out Dave's points, demeanor, and moderation on this forum. Fantastic job at this, Dave.?
