content: Greetings EEVBees:--Be sure to save those old parts, you just never know. I just happened to have a couple of old Fluke 87 jack receptacles, one with the V/Ohms jack broken and one with the COM broken, so I made one good one using JB Weld. I have previously bought junkers just to I could get a free jack receptacle, by selling off all the other parts. The cheapest I could find the receptacle on eBay was $32, and I am too cheap to pay that much."Say little about what you know and nothing at all about what you don't know."Sadi Carnot 1796-1832Best RegardsClear Ether

timestamp: November 28, 2014, 01:59:49 am
content: For how the memory works, it is likely that pressing the equals key stores the current result in the memory. Which means the MR key will recall the result of the last calculation to include in the current calculation.For percentages, try 100 * 10% (will likely give you 10), then press the + key (will likely add 100 + 10 to give 110). You may need to press the = key after the plus key (try it and see).

This also relates to the in between cabinet connection. Although I do know how to draw and design electrical schematic (for electronics & PCB) I have some doubts about doing the same for wiring design.Anyways, this kind of work is done by the SW tool called ePLAN Electrical. I'm sure many of You have heard of.This is one of many examples:My questions here are:- where from to learn how to draw technically correct wiring diagrams- some dedicated literature- are there some examples (.PDF) that one could study how it was done- can someone who has done something similar share a thought on this issue?To start with, ePLAN tutorials are available and that's a great help.Thx

In addition, I would doubt that the permanent fitting of non-ETSO authorised kit in the panel is allowed on EASA aircraft. We get away with that by running spaghetti wiring from the lighter outlet and several suction mounts. Typically I run a Garmin 495 and an iPad this way.Of course, I could always get a US callsign and re-register the plane as an N-reg...

However, if you were saying things that were untrue or lack of facts to back it up about the product or manufacturer, then you could have some legal problems for slandering their name.

I mean it's definitely surprising and all, but after all the floods brisbane has had, this was over much quicker and fewer people were hurt.Apparently the State Emergency Services (SES, a government organised group of volunteers who go to help people with damaged houses etc during storms) received almost 1500 calls in the space of a few hours. But they couldn't do anything straight away, because if you took your car outside the windshield would likely be smashed.

He experimented with using jute (dielectric substance) to polarise microwaves, in a similar manner to a sugar polariser at optical frequencies.I wonder how easy it is to do this kind of thing as a hobbyist?He uses a spark gap to produce the microwaves but how is it tuned? Perhaps the sphere act as a resonator?The receiver looks just as interesting, perhaps a biased diode connected to as suitable antenna would work?

Spark gap transmitters have always been notoriously noisy, both in repeat rate (except for a few CW methods, which were probably still very hissy, but could at least accommodate intelligible voice) and bandwidth (without careful filtering between generator and antenna, expect bandwidth as a sizable percentage of center frequency -- not to mention harmonics!).Tim

Easy choice.Edit: To be fair, as the item listing heading is correct (logic probe), the seller probably does know what it is. His 'oscilloscope probe' in the description is probably just a mistake from reusing another listing text.Not important though. Can't complain at that price. I also bought a 10525H of his in another listing.

content: Greetings EEVBees:--See below link for an article from Boing Boing about Dr. James Woodward of California State University at Fullerton and his thruster which does not require reaction mass. Its principle of operation, uses Einsteinian relativity to change the inertial mass of capacitors. Or as Dr. Woodward describes it:"In principle, you could try this yourself by using a stereo amplifier to power a speaker that has been repurposed to vibrate a capacitor at, say, 20kHz, while you would also charge and discharge the capacitor at 40kHz."--I know it sounds crazy, but this guy is getting some serious attention from some important physicists. Also NASA is playing around with a potential reactionless thruster, based, as near as I can tell from the the limited information available on the Casimir effect. See second link below for an article about the NASA effort.--The reactionless thruster would indeed be a form of Anti-Gravity, and combined with something like the Polywell reactor, and could take us to the stars, tout de suite. That toot sweet for those of you from the Big Apple.--No doubt some of you understand what these folks are talking about better than me and my bone head level physics and calculus.

Two weeks later, still no luck.Then I contacted them again and they said my package "had been stopped in HK security check due to lithium batteries" etc. Then nothing for several weeks.I contacted them again (now not so happy anymore). Then I got another tracking #. This also non working. After several reminders ... and more weeks ... nothing. Tracking still no good.Now I sent an e-mail that unless they refunded me I would have to contact my cc issuer and report them and demand a refund from the cc company. Still nothing. Then I reminded two times. Then suddenly a THIRD tracking number was sent. This time the package was delivered in Netherlands.What is going on with DX at the moment? Do they have serious problems?
