    - If you're doing higher speed analog, lower-frequency RF or switching power supply design, I'm a huge fan of the Tektronix DPO series. I use a TDS3032.

    If you're doing RF you're going to want a spectrum analyzer sooner rather than later.

    If you're doing low freq / high power discrete analog (aka SMPS) you're going to want a curve tracer sooner or later, to fool around with if nothing else.

    The original article poster has it all wrong, in that a lab that has nothing but an empty desk and a $2K scope simply can't handle the jobs that are easy in a lab with a $500 spectrum analyzer, $250 scope, $750 worth of Hakko (de-)soldering gear, a universal eprom/uC programmer, a logic analyzer, maybe a low end HP protocol analyzer... etc. Don't forget the "obvious" material handling equipment like $500 worth of lights on arms, magnifying glass on arm, low power binoc microscope, ESD protection gear, etc.

    Typical rental contracts work out that if you borrow a piece of equipment for 4 months or so on a daily rate with no long term discount, only then is it cheaper to actually go out and buy one. This is the option we take at work.

    Good advice for personal relationships / dating also. Seriously though, the most important reason to rent equipment is to try out a couple different machines before buying one of them. You will find various peculiarities in the specs may or may not be important. Or the user interface of "X" brand scopes might be perfect for you or drive you completely insane.

    What lab will reject an instrument "due to it being fixed"?!

    You used a 10% resistor that seems "close enough" the original was 1%. The calibration lab is used to making "minor tweaks" but having to twist all those trimmers practically all the way is going to take forever and piss them off. On the other hand, in Moms Basement, watching a Star Trek movie marathon while calibrating a scope is considered fun, not a waste of time.

    You used inductive metal film resistor which screws up the high frequency performance instead of the specified non-inductive carbon comp resistor. It'll never work above 90 MHz again. The calibration lab will throw a fit because it won't calibrate at 100 MHz. However in Moms Basement you are thrilled to own a "90 MHz scope" even if the front panel label claims its a 100 MHz scope, especially since the highest clock frequency you'll likely subject the thing to anyway is probably low double digits.

    You used the totally wrong temperature comp capacitors, and trimmed the rest of the scope so it'll work fine at 70 F. Unfortunately the industrial specs say it has to be calibrated from 32 F to 125 F so it simply can't pass calibration. The calibration lab will throw a fit, although it works fine in Mom's temperature controlled Basement.

    That's before you start trying to mix old Tektronix scope silver bearing solders with traditional Pb/Sn and with modern lead free. I understand old fashioned Pb/Sn solder will corrode the plating off the Tek silver solder ceramic things.

    My Tektronix 585 is fine for a modern end table. I got it for free and it still works. :)

    I had an O-12 in the 80s.

    Any scope is better than no scope. If you don't have the education and skill to understand how the input amplifier distorts signals, then you simply have to spend huge amounts of money on a "distortion less" scope with specs ten times higher than you need. Also if you work for a semiconductor manufacturer and need actual quantitative measurements you need amazing specs.

    However, if all you need is qualitative, (is my 20M transmitter oscillating? Is my microcontroller sending pulses?) then a cheapy scope is all you need.

    Um, maybe getting a license would have brought to light the problem that caused the pool to fail, like uneven ground or poor construction. I know, it's crazy, right?

    At least theoretically, in court it'll be easier to prove it was a material defect, since before the implosion or whatever, a "skilled and neutral third party", that being the inspector, claimed it was properly installed. Otherwise the big corp is just going to weasel out and blame the homeowner/installer for everything.

  13. Re:They collected $75,000... on Officials Use Google Earth To Find Unlicensed Pools · · Score: 2, Interesting

    I know I'm taking a leap here, but I'm assuming the license requires the homeowner to purchase a permit to install the pool, which should have been inspected

    A safety oriented inspection should not require over $30.

    This is pure money raising. $75K/250 pools is $300 per pool. Assuming the "usual" double fee if applied for after work completed, that would be a staggering $150 to pay a city employee to verify there is in fact a fence and a GFCI.

    I can safely assume you've never actually participated in a permit inspection. I have, many times. Mostly involves an older semi-retired inspector glancing at the work and driving off. The longest, most detailed inspection I have ever been involved in, oddly enough was a dishwasher where the inspector actually bent over to examine the power wiring (GFCI outlet? etc). That was like 90 freaking seconds, at least three times longer than all the other inspections I've participated in.

    1. Foundations under the roads would have to be completely redone to support the extra weight, trains have large supports under the rails to support the weight of the trains, so its not just a simple cut holes put in rails, and drive.

    Looks like the rails steer it and regular tires support the weight.

    I imagine old fashioned cable cars (frisco?) work the same way, in that the cable provides the "pull" but the cable cars do not by any means hang from the cable. (an Aerial Tramway is a totally different concept and does in fact hang from the cable)

    The vehicles have a small surface area that contacts the ground

    I would not worry so much about tire friction as about wind surface area. Coasties are supposed to know all about hurricanes, but even Chicago "the windy city" can't use these. The center of gravity being extremely high, I'd think the odds of overturning in a breeze would be high.

    Heisenburg DID say that you CANNOT know these things, that they CANNOT be measured, that it actually kinda seems like you CAN.

    close but not quite.

    A better way to phrase it is Heisenberg showed that you can take all the measurements you want of either individual measurement but (more or less) the standard deviation of a combined measurement is always going to be some small number, which turns out to be irrelevant for big things (cars, etc) yet comparatively huge for little things like electrons.

    Newton certainly ruled things out. Regardless of weight or density, organic or inorganic source, soul or soulless, gravity accelerates stuff downward around 10 m/s/s. F=MA, who cares about V. F=MA who cares about mass density. Einstein wrote a hell of a lot of interesting papers so I suppose he was on both sides of everything at one point or another, but one example was the photoelectric paper helped ruled out the "ultraviolet catastrophe" of blackbody radiation.
