And checking the current ACMA limits they finally increased the allowable 2.4GHz EIRP to a much more useable 4W, though try to clamp down on anyone using that new power for useful transmissions.

content: It shouldn't be hard to water cool a wire wound resistor,as water cooled RF resistors have been used in Test Loads for many years.They are not wirewound,but the idea is the same:-Run the cooling water through the porcelain former,making sure the conducting part of the resistor can't make contact with the water.OK,now I watched the video,I realise they are showing how their resistor can stand an overload,rather than presenting it as a new concept.I did notice that the other maker's device wasn't a similar construction,neither was it the same resistance.A bit cheeky,Vishay!!In any case,it is standard practice to place an interlock switch,which will detect loss or water flow & turn equipment off fast enough to avoid damage.

You’ll be among the first to know when we make Windows 10 available for the Raspberry Pi 2.We will also continue to support the Intel Galileo through the program.By being part of the Windows Developer Program for IoT you continue to be amongst the first to receive new information about the program, product announcements, beta program updates and launch specifics.Thank you,The Microsoft IoT Team

content: A friend that teaches electrician classes at local college gave me this thing today when he was moving his office. I Guess nobody needed, or wanted I guess he figured I could find some use for it.It's a Magnatek GPD 503. Here is a manual:http://igor.chudov.com/manuals/Yaskawa-GPD-503-Manual.pdfHe said he thought I could just put a wall cord on it for 120 and make it drive a 3 phase 120V motor. The specs say 3phase like 300-400V.If I can power it somehow on 120 I may be able to use it as a signal generator of some sort. He seemed to think it worked, but i don't know why they don't need when the deal with PLCs, etc like this. Makes me think has some issue, some reason they can't use, or it's really outdated.If it's possible i'd at least like to test it, or see if his idea is even possible.

content: That's about a 10kW drive. That's about the right size for a riding mower or go kart, but the high voltage makes it impractical to run from batteries at that power level. Best use I can think of (apart from selling it) is to run it off a voltage doubler from a 240V line, then run a 480V three phase motor such as large power tools or even a surplus 480V HVAC compressor.

If i modified it so the SMPS in it would run on something else maybe it would run a smaller motor ok.Seems to me if can get the logic to power you should be able to just use one or two poles. All it is is some logic, caps, some beefy transistors and a cooler.

Same with the icons on the desktop, again this is not something happening after a long period of time, it is very quick.Is this a hardware related issue on the monitor, maybe bad caps ?These monitors were used on a hi-tech company office or lab and people sometimes don't care about them.I already checked for the cable and run a program to de-ghost the monitor (which worked) but after de-ghosting I got ghost image back very quick.Please comment.David.

content: I have inherited a Rode pex 35 Condenser microphone from a sadley deceased friend, and I'd like to use it. However, I looked on the Rode website for information about it and there is none (I can only presume its an old model). Googling only reveals a couple of hits mostly of people selling them.I'd like a manual or something, but specifically I'd like to know:Does it require phanom power, and if so what voltage?Presumably the "active" face is the one with the cardiod symbol on it?Any other usage info I should take into account?I'm planning to use an Alesis IO-2 Audio interface which does do 48v phantom power if needed.If anyone has any info it will make me happier about plugging it in

content: Hi Slothie,Yes, I believe you'll need phamtom power for this mic. Phantom power is most commonly P48 (48VDC) but some mics will also accept P24 (24VDC). I think the NT-1 replaced the PEX.The cardioid symbol you refer to indicates that the mic is sensitive to sound coming from the front and sides but rejects sound from the rear. That is your pick-up area. You'll be able to hear the difference.

timestamp: November 12, 2014, 07:50:08 pm
content: Looks like some researchers have made what could be an almost holy grail type device for RF communications: A non-magnetic circulator.The press release makes it look pretty impressive and it looks like it's made entirely of passives plus a frequency generator that sets up a wave inside the circulator itself to take the place of the magnetics. If anyone can get a hold of the nature article I'd love to hear more about how it actually works. Given that it looks like it's not using any exotic materials either it might even be possible to put it into an IC.http://www.utexas.edu/news/2014/11/10/radio-wave-device-alu/http://www.nature.com/nphys/journal/vaop/ncurrent/full/nphys3134.html

content: Yea I'm not optimistic about it for cell service but I do think it'd probably work really well for WiFi or other short distance scenarios. I have no idea how this would play with MIMO devices though since there's separate antennas that would possibly interfere with the function of the circulator. I'd also think this could enable some much better ISM band low power rf transcievers. Imagine having a full duplex 433mhz transceiver without having to use more bandwidth and/or negotiating which frequencies/channels to use. Bluetooth could probably make some real headway with that also getting better latency since there's no contention on the media for full duplex audio.

A buddy of mine had a very simple board laid out for him by what would appear to be a student found on an online site, I think the student was in India. That cost him US$70, I counted 13 parts on it plus a breakout area, all through hole.Certainly not something I'd want to do full time, it would drive me potty, but I quite understand people who do enjoy a living out of it.

I won't repeat here apart from the basic facts:- 1/4 realtime encoding speed is normal for 50fps. 25fps is twice realtime. The price you pay.- Forget GPU acceleration, it doesn't help. CPU is everything.- Fastest compressed encoding for 50fps video in Sony is using the Sony AVC codec. Only way to get quicker is with some form of Debugmode Frameserver type system, or direct AVI uncompressed output, but huge temp file sizes and in the end not much in it in terms of speed increase.- Don't believe anything George Graves says on this topic

Those are passive probes, with switchable x1/x10 attenuation, rated at 150MHz bandwidth in the x10 position.It's fine to get probes with more bandwidth than your scope, and that's what Rigol does with their default probes. Passive probes with this magnitude of bandwidth aren't very expensive, so it makes sense to get probes with a bit higher bandwidth than the scope.
