Premium Members William Demeritt Posted July 2, 2011 Author Premium Members Report Share Posted July 2, 2011 AJ: Yea, AMIMON introduced the sticks back in October, but they did it as a "see what you can do?" type of thing. I think LG Innotek showed off the first "stick" at CES, but nobody's really brought it to market yet. I'm interested in seeing the range on them!

Premium Members Tim Moynihan Posted September 10, 2011 Premium Members Report Share Posted September 10, 2011 William, just watched the Brite-View test you shot...wow, that thing shows some serious promise!! From what I understand the Amimon chipset used in the Brite-view is the 3rd generation and latest (I think). The Boxx Meridian uses the 2nd gen and the Camwave used the 1st gen. I believe that's how it is. I was amazed that the picture held so solidly when you walked a pretty fair distance and behind more than a few walls. My Boxx would never deliver that kind of picture unless, perhaps, I had the high gain receive antenna. Did you do any mods to the Brite-view receiver? Watching closely...great work, man.

Premium Members J. Christopher Campbell Posted September 14, 2011 Premium Members Report Share Posted September 14, 2011 Thomas, The external antennas are rather crude on this prototype, but I think my final version will look similar: Not shown is my power cable, which is simply an AUX power LEMO for my PRO, runs to a 12/24v -> 5v transformer (big grey heatsink), runs out to a simple DC plug. Basically, they're 4 wifi antennas specifically for 4.9-5.8Ghz range mounted to SMA connectors on pigtails. The pigtails are cut and soldered down to the PCB antennas inside the AirSync HD. I don't own a spectrum analyzer, or I could have verified their actual broadcast output, but when I removed the antennas and did my "walk", the signal didn't carry as long, so I know they're contributing. Probably by mid-June, I'll have my final proof-of-concept finished and I'll begin showing my presentable version. Depending on the popularity, I may sell my conversion as a service for people who are interested, but that depends on other factors. This is all fantastic work!!! I am thrilled to have a low cost option on the horizon. Can you post a pic of what got soldered to what on the inside of this box? I would like to see exactly where the pigtail was soldered! Again, this is great! Quote Link to comment Share on other sites More sharing options...

Again, this is great! Christopher, I'd prefer not to show off what I did inside, but I will say this: if you look around for soldering tricks related to adding an external antenna to a wifi card or PCB, you'll see where I got my idea from and probably what I did. Once I get something I'm confident with showing off, I'll show all. Thanks! Quote Link to comment Share on other sites More sharing options...
Ben Miller Posted September 16, 2011 Report Share Posted September 16, 2011 I'm a bit confused. Judging from pictures of the unit, there are no external antennas. Were you able to add on better antennas, and if so, which ones did you use? Thanks! Brian Freesh helped record me and my walking path, while a second camera recorded the monitor's live feed from my transmitter. I did the walk a few times, and during none of those trips did the image break up, pixellate or drop out. I removed my external antennas during one walk, and the image did distort.

eric wahl Posted February 12, 2012 Report Share Posted February 12, 2012 For those of you who have a P-Tap off their battery plate, I am going to try this solution for power. Switronix XP-AJA-5 Ptap to AJA 5v Cable http://www.bhphotovideo.com/c/product/729796-REG/Switronix_XP_AJA_5_XP_AJA_5_Ptap_to_AJA.html Is has the appropriate power reduction to 5v 3amp I will cut the end and add a 2.5mm DC Coaxial Plug I will post the results in a few weeks.

Premium Members William Demeritt Posted February 12, 2012 Author Premium Members Report Share Posted February 12, 2012 Eric, that's a hefty investment to cut up in order to power the system. Why not buy a D-tap kit ($22), a 12v to 5v transformer (something 3 amp capable, they're out there on Mouser.com) and the DC plug? Probably could assemble that for less than half the cost of that Switronix device. Quote Link to comment Share on other sites More sharing options...
Premium Members Afton Grant Posted February 12, 2012 Premium Members Report Share Posted February 12, 2012 D-tap (P-tap) kits are $15 at B&H. 5V Voltage reg should be around $5. DC Plug would be a couple bucks. Cable would be $1/foot at most. Save yourself way more than half. Quote Link to comment Share on other sites More sharing options...
Premium Members Mark Schlicher Posted February 12, 2012 Premium Members Report Share Posted February 12, 2012 Then there's the value of one's time. I spent a lot of time researching the right voltage regulators and project boxes, etc. I saved a bit of money but wish I'd just bought the Switronix cable. It's no more expensive than many other custom cables... Quote Link to comment Share on other sites More sharing options...
Premium Members William Demeritt Posted February 12, 2012 Author Premium Members Report Share Posted February 12, 2012 Mark, other custom cables are rooted in the real world price of LEMO, Hirose and Fisher connectors, and with those plugs comes the expertise of soldering cables into very small pin receivers (many of which are in the center of a circle and blocked immediately if you solder in the wrong order). This is a VERY simple assembly. If you'd rather have someone else build it, that's fine, but I would imagine even your favorite wiring expert or cable builder would tell you $130 is wildly overpriced for what should be a very simple idea.

Premium Members Mark Schlicher Posted February 12, 2012 Premium Members Report Share Posted February 12, 2012 Hi, Will, I understand your points and I don't necessarily disagree that the cable is pricey and maybe out of line if you already own the skills and soldering tools, and know just what you need and where to source the parts. But the "real" price of DIY goes up when you attach a dollar value to your time, including the time to research and source what you need via online or dragging yourself out to the ol' Radio Shack, paying tax and/or shipping on top of the prices quoted above, etc. Plus the cost of a soldering iron if you don't already have one. My guess, though I haven't formally priced it, is that the cable would probably cost about $80-$100 to have a cable builder make a proper custom version. (Parts plus an hour's labor plus shipping). So, though the Switronix may not be the cheapest or "best" option, it's still a viable choice, depending on your point of view... Quote Link to comment Share on other sites More sharing options...
eric wahl Posted February 13, 2012 Report Share Posted February 13, 2012 It's time thing for sure... I also like the professional housing that the voltage regulators from Switronix come in. It will look cleaner than anything I can put together.. Quote Link to comment Share on other sites More sharing options...
Griffin P. Nash Posted April 13, 2012 Report Share Posted April 13, 2012 Hi William Demeritt, in reference to: I built my own power cable with a 12/24v transformer that draws power off my AUX port and converts it to 5v. The transformer handles up to 6amps, which is good since the transmitter requires 3amps. My next task will be to build D-tap power cables. How did you power the Air Sync Transmitter from sled. I recently purchased an Air sync for my Zephyr rig and am looking to be able to power for shoot coming up with Sony F3's simultaneous sdi/hdmi out. I have been research 12volt-5 volt regulators but have been unsucsessful so far to find a 3 pin lemo to 5 volt regulator to dc connector for air sync. Any suggestions would be appreciated. Thanks Griffin Quote Link to comment Share on other sites More sharing options...
Premium Members Tim Moynihan Posted April 15, 2012 Premium Members Report Share Posted April 15, 2012 Hi guys, I have a BRITE VIEW Air Sync HD (BV-2322) for sale if anyone is interested. It is brand new in box, never used. Still wrapped in original packaging. Send email to: rocksteadi@telus.net $200.

jacob varley Posted April 29, 2012 Report Share Posted April 29, 2012 It's almost as if this has taken a sudden halt in progress. I am VERY interested in an inexpensive solution and have taken it upon myself to create a good, reliable rig. my research is going well, and my tests as well. I can't post anything as a full conclusion yet but I will post pics of the unit, the mods, and the distances I'm getting. I don't know if anyone is interested but I'm working on a setup that will give you loooong range. you need a grid antenna but if you can tether to a power source, then this would work fine.
