Sony ECM W1M Bluetooth Wireless Microphone System on A7r for video see: www.youtube.com/watch?v=bh1w5wtJS9w
Sony ECM-W1M Bluetooth Wireless Microphone System for HandyCam Camcorders and the new Sony A7 and A7r mirror-less camera systems.
First, let me point out two big advantages to this system: 1) It's compact and you can easily carry the receiver and transmitter/mic in your pocket so it's always handy; 2) It's simple to use. Just put the receiver on the Sony universal hotshoe on your camera, turn on the mic/transmitter and it just works. You can even plug in a high quality Giant Squid Lavalier mic for even better sound quality.
In this first-look review I test the system for range and I plug a Giant Squid Lavalier mic into the mic input on the bluetooth mic / transmitter to see if that works. This is a very compact and easy to use wireless mic system that seems to work pretty good.
From Sony: Special moments right at the source with this Sony ECM-W1M Bluetooth Wireless Microphone System. Not only can you record crisp, clear sound up to 300' (91.44m) away, but you can also enjoy two way communications between you and your subject. This unique feature enables you to give your subject direction while capturing only their voice, or you can chose to capture both their voice and yours while filming.

I'll apologise in advance for any injuries that may occur if visitors fall asleep while reading this post. I probably should have added a "Geeky Content" warning to the title. If you feel drowsy or experience partial paralysis of facial muscles as you wade through this material, try giving yourself a quick, hard slap and move on to something less stupefying before you fall from your chair and do yourself harm.
Today's subject is freedom. I'm drawn back to Dr. Martin Luther King Junior's famous speech in which he quoted an old spiritual song containing words something like, "Thank God almighty, I'm free at last."
My strategic plan all along in my War Against TELIKOM has been to connect to the Internet without any ghost of signals passing through any of its antiquated, poorly maintained and evil equipment. I feel that victory is rapidly approaching. I expect that, by this weekend, I shall be able to sit in my house and connect any time that I please for as long as I please and download as much as I please with never a fear that I will face an exorbitant fee or lose my connection every five minutes.
How can this be? Well, unless your uncle is Daddy Warbucks, you have to have some help. The first battle was won when our organisation purchased a third-party Internet satellite dish, called a VSAT, if you care. I'm trying to avoid too much geek-speak, as it bores the life from me. We've had the satellite Internet connection for about a year now, and it's perking along nicely. We lose it only when it rains torrentially.
So, the question became, how can I tap into that gush of free bytes? Friends come in very handy here. I happened to have one who is the most renowned guru in the land and a geek among geeks.
Well, I can see already that I must shorten this story. I'm beginning to feel sleepy myslef.
Anyway, Mark came up with the idea of connecting to my house by wireless signals. The rub is that these pesky little beams refuse to penetrate anything but air, at least if you plan to go further than a few tens of metres.
Climbing to the top of this old amateur radio tower at the back of our office, I was disappointed to find that I could not see our house: So, the problem became: what can I see from there which I can also see from my house?
I'll digress a moment to refresh myself by showing you the pile of junk that is typically required to get all of this working; It's mostly on the top shelf. You can see, from left to right, a satellite modem which talks to the gizmo up in space and a "router" which splits the signals up somehow and distributes them to the correct computer. These are the essentials, except for the actual wireless gear, which is coming up next. The black box is a "hub" which simply lets you plug a whole bunch of computers into a network and sorts out the torrents of information that flows through it. Below is a UPS which prevents the evil PNG Power from devastating our investments and an old computer which I use to keep tabs on what is going where.
Here is a picture of the front and back of the long-range wireless units. They include a gadget which sends and receives wireless signals and a highly directional antenna which concentrates the beam and allows it to travel much farther between units: A clever bit is that there is a little doohicky which you plug into the wall to provide power through the cable which also carries the network signals. Therefore you need only one cable going to this unit. It's called Power Over Ethernet, but the very sound of that causes my eyelids to sag.
Here is a Google Earth shot of Madang showing the plan to get the web from our office to our house: One unit goes on the ham radio tower at our office. Two units go on the security camera pole that the coconut oil refinery. They talk to each other, to keep the signal going, through a short piece of network cable. The green lines represent the wireless radio beams doing the magic.
So, having gotten from the office to the coconut refinery, we shoot the second beam way across the harbour to the front of our house. Here is a view of town from our veranda taken with my mighty Olympus SP-590UZ at it maximum of 26x optical zoom: You're looking almost a half-kilometre at that little pole in the middle of the frame. It's got security cameras mounted on it already. From that pole I can see the tower at the office and my veranda.
Therefore, I mounted the last unit beside the front door of our house and ran the POE cable to the bedroom wherein lie our thirsty computers: I didn't realise until I saw this picture how much our house needs a coat of paint.
Tomorrow will be the magic day, if it doesn't rain, when the hop units will be installed on the security camera pole. Everything else is installed and powered up.
This weekend I hope to enjoy TELIKOM-free browsing. If it works, it will be magic. If it doesn't, it's back to the drawing board.
A BT Voyager 2091 - this services our entire house, including all the stuff in Tim's office/studio on the top floor. (Update (Dec 2007): this connection used to be made via a wireless Ethernet bridge, but it is now connected via two HomePlug 85Mbps adapters (i.e. Ethernet over the power lines in the house).)
The router carries the unofficial hostname of 'kamidake' (following the naming convention on the home LAN of characters from 'Tenchi Muyo' - it's a long story), but the name is not really used.
Commemorative plaque detailing the history of the former Marconi Wireless Telegraph (and Signal) Company works at Hall Street on the outside wall at The Woolpack Public House on Mildmay Road in the City of Chelmsford in Essex (UK).
The Hall Street Works was located directly opposite The Woolpack and is credited as the first radio factory in the world.
The building itself was constructed in 1861 by John Hall as a silk weaving factory. Mr Guglielmo Marconi with his Marconi Wireless Telegraph and Signal Company took over the building to create the world's first radio factory in 1899 and was occupant up to 1912 when the nearby and much larger Marconi 'New Street Works' were constructed.
In later years The Essex and Suffolk Water Company amongst others were site residents. ESW left in 2010 and now the former radio factory is a collection of luxury apartments.

RFM12B wireless remote flash module.
This timing give the results how fast the RFM12B module can reveive a 16 bit flash fire command. The module is set to 868MHz and the transfert speed is 115 kbaud. A special sync system is added to fire very fast and reliable between transmitter and receiver.
The timing diagram show the time need between tx and rx (cursor A to cursor B) and is here only 429 usec. Both RFM12B modules are driven by the FPGA hardware in this testcase. This is done considering my highspeed setup for flying insects works with this hardware. But the reveiver part can be done with the AVR controller as well.
SPI speed is set at 2 MHz into my FPGA hardware. For highspeed photography the remote wireless flash need perfect synchronisation with the flash on my basis setup. If the time between the remote flash and the other flashes is different, then the highspeed results show double pictures resulting in blured pictures as a result of this flash timing delay. My hardware calculate now how much power is used on the remote flashes, the fire delay of the RFM12B module and the power on the fix unit. Adjusting all this timings give a perfect flash light all on the same time even is the power change between the systems. Ofcourse the remote flash power is also adjust by the remote wireless module.
The transmitted fire codes here are 43h and 47h. Ofcourse this codes can be changed into the controller if needed.
I will add more info in the near future.
Update 2009 07 28:
An update on the protocol sequencer and the fire command set to 8 bits after the 16 bit synccode give now a delay of only 360 usec between fire command and trigger received. This is the fasted possible transfert with a 8 bit fire command. Now I will test this at longer distance to see how reliable it is.
Update 2009-07-30
New tests are done. Setup of 2 units at longer distance and 2 walls at 115 Kbaud give a reliable 100% flash fire. Delay between command and flash was 360 usec.

Taken for the group MacroMondays, this weeks theme, Frustration.
This was the perfect theme for me this week. My MacBook, after connecting to the wireless perfectly for the last two years, has suddenly decided that it does not want to do it anymore. It either tells me the password is incorrect or that the connection has timed out. I can't not find out how to fix this anywhere on the interwebs, and I'm getting closer and closer to throwing the computer out the window and then following shortly thereafter.
So this is my airport express, blinking amber, because it can't connect to anything.
A research team led by INL Chief Wireless Scientist Hussein Moradi has developed a wireless technology platform that identifies and utilizes available spaces in the radio frequency spectrum that are not occupied by other signals.
