Question about Rode NT1000 - Page 1

timestamp: October 09, 2014, 09:12:31 pm
content: So I have a question about this microphone that I own and has been featured on the channel. If I touch it at all, it goes deaf, for maybe 20 seconds. Is this normal for this microphone? I bought it at a discount so I was wondering if maybe this is a fault? Even if you touch it with your nose, it can go silent. I would have thought it would be electrically isolated from the case but mine isn't judging by the way it behaves.

content: It is powered, I've just tried it again and the issue doesn't seem to be related to touching, I can hold it and it works fine.But it does sometimes stop working after being handled/moved, I can only assume my cheap microphone cables could be at fault here?. Maybe the connector is loose and I'm disconnecting the power inadvertently? I guess that's a lot more likely.

The Art of Electronics seems too complex while Practical Electronics is too full of errors.I might recommend "Electrical Engineering 101" by Darren Ashby. Maybe along with a very simple starter book such as "Getting Started in Electronics" by Forrest Mims.

Also i wondered if they might have managed to get more than 240FPS in the WVGA mode.But alas noI guess it saved me spending £360 quid on it!maybe i should save up for a Phantom?

It just wouldn't lock onto a signal and I have no idea why. Every other camera I used worked flawlessly (Canon, Sony, Panasonic). Perhaps there is something funky going on with the HDMI output on GoPro cameras?

A manufacturer I know of here in Melbourne has laser soldering equipment. It is slow and in general is no replacement for reflow ovens and metal masks. But laser is better than hand soldering because it is a tightly controlled process. It has its place.

They were at one time available on Youtube in low res versions.Some of the early chips they would weigh and then soak in Freon. After a while they would pull them out and re-weigh. Any that gained weight were rejected because that meant there may be imperfections in the casing. Little old ladies would weave the programming into rope memory. Workers assembling the gyros were discouraged from bathing or getting sun tans because flakes of dry skin could end up inside the gyros and cause them to fail. All kinds of little tid bits of info like that.

As well internal traces of about the right length that they all act as small antennas and couple the energy right into the silicon inside, at power levels about 6 orders of magnitude above the design specs. Exploding battery will be the least problem there, the exploding display, boards and such will go first, as the foil pouch of the battery will provide a few extra seconds of shielding before it arcs away totally.

content: I see it as a painless order fulfillment service. If I develop an open-source hardware design and link to the OSH Park project on my blog (or whatever), then others can follow the link and get the PCB made with a minimum of effort. Saves having to download Eagle, create Gerbers from the project files, find a provider that can make them, etc. etc...To anyone with a little PCB experience, it's probably not an obvious advantage. But in the world of Arduino and kits, it's one less thing a budding hobbyist would have to deal with. Its success is entirely dependent on those contributing though.

content: Quote from: SirNick on September 26, 2014, 06:44:11 pmThere is the simple advantage that you don't have to generate and upload the fab files to OSH Park if you want to use someone's design. Another opportunity to make it easier for someone to use your design without too much effort from your side.It's a nice enabler that doesn't block any other options.

It's expected that those making valid claims will receive a minimum payment of $25.Under the agreements, Samsung Electronics Co. Ltd. and Samsung Electronics Canada Inc. have agreed to pay $21.25 million, while Innolux Corp. (successor to Chi Mei Optoelectronics Corp.) has agreed to pay $10 million.Also included in the settlement is Japan Display Inc. (successor to Hitachi Displays, Ltd.) on its behalf and on behalf of Hitachi Ltd., Hitachi Canada, Ltd., Hitachi America Ltd., Hitachi Electronics Devices (USA) Inc. for $3.15 million; Chunghwa Picture Tubes, Ltd. for $2.02 million; and Epson Imaging Devices Corp. (formerly known as Sanyo Epson Imaging Devices Corp.) for $1.2 million.The case is continuing against five other groups of defendants including LG Philips LCD Co., Sharp Corporation, and Toshiba Corp.

Then it sold.It was a Tektronix DSA602 'Digital signal Analyzer' - a weird looking scope with plugin modules and FFT.Also two P6204 1GHz FET probes included, which alone were easily worth the price, even _with_ the bill for shipping to Oz.The strange thing about the listing was that the seller pictured the scope sitting face down. Whether it had a front cover on it, or was just sitting on the controls, I couldn't tell. The seller is one of those 'vast bulk, little idea of what anything is' types.I've no need for such a scope, and I've used up my current spending allocation anyway. Was still vaguely toying with the idea of buying it, checking it out then reselling locally with better pics and description. But I'm broke again and couldn't afford the shipping.Still I'm dying to know if it actually had a front face, and whether the thing works. So I'm really hoping someone here bought it.If I ever buy one of the 602 series for my own old scopes collection, it would be a DSA 602A.

We all speak "electronics" and attempt to communicate with each other, mostly in BrEnglish or AmEnglish or OzEnglish (which are close enough for practical purposes).But when people ask about local vendors, or local power, or local spectrum, or customs and shipping, or several other things, it becomes critical to know exactly where they are coming from, in the practical, geographic sense, if not in the philosophical sense.

content: Greetings EEVBees:--The memristors are coming. Just as Flash Based SSDs are getting cheap and cheerful, they may be bowled over by an upstart. See below a very interesting presentation by Martin Fink of HP (after an introduction by Meg Whitman at about 3:50) of a completely new unified CPU and Memory architecture based on memristor technology, called the Machine. Comments by the knowledgeable, and speculation by the less knowledgeable like myself, are solicited.--Head of HP Research Labs Dr. R. Stanley Williams recounts how his team came up with the idea of using titanium oxide for functional, practical, memristor arrays, bringing to life the ideas of Leon Chua. This is a very interesting lecture for those of you who have not seen it already. It is called Finding the Missing Memristor.Fairly recent lecture by lovable Dr. Leon Chua, the man who divined the existence of the 4th class of passive components called memristors some 40 years ago which started the ball rolling. People had seen memristor like behaviours in experiments before, but had not really known what they were dealing with. Dr. Chua explains this history in a most interesting way, with very little math. Even the equations require only first year Bonehead Calculus to comprehend."The language of experiment is more authoritative than any reasoning: facts can destroy our ratiocination—not vice versa."Alessandro Volta 1745 - 1827Best RegardsClear Ether

Cringely posted a withering critiquehere.The memristor itself looks like a fascinating and revolutionary device.Stanley Williams is obviously brilliant and passionate about his work - it's interesting to note that according to theirrecordshe is no longer a director at HP - merely a researcher.Below is a more recent version of his lecture on "Finding the missing memristor" which incorporates the results of another two years of research and development. It's twice as long, but well worth the effort:

content: That is because of the stupid monitor design. I've seen that on one Dell monitor. There is power going from the computer to EDID eeprom (dual powered), there usually are 2 diodes in the monitor so the IC is powered from both sources. The thing is, monitor must not power a graphics card.There is also another case with out of spec Displayport cables. There is one 5V wire that must not be connected according to spec. There is 5V pin on both ends intended to power active adapters and similar stuff. But they are not allowed to be connected together in the cable (tell that Chinese jerks). I've seen that myself with ebay Displayport cable which make computer unable to boot, also a spinning GPU fan if connecting a second monitor with the same cable. So I opened the connector and cut that nasty wire. There are actually a shitload of complains on forums about bad monitors which make computer unable to boot when connected with displayport. But they don't know that it is all about crappy cables.
