Remember that this initiative was out of the UK originally and was aimed at turbocharging the CS curriculum at the University of Cambridge’s Computer Laboratory. I'm amazed they've done as well as they have in the US given they didn't get FCC certification until April 2012; literally minutes before they went on sale.

I ordered 5 from newark.com on November 17th. They were shipped on Nov 27th. Three were defective - I RMA'd them on Jan 7th and got the replacement ones (which were all ok - whew!) a 3-4 days later.

From their website: "7200 Expected to ship 6 Feb, 2013". When I ordered mine they were backordered until Dec 26th, but mine came early. I assume their estimate is worst-case.

Go ahead and order some - they won't charge your card until they ship, so you're not out anything. I know one thing for sure - you won't get any unless you bite the bullet and order some!

Fireflies Bring Us Brighter LEDs

A band of ingenious fireflies, in a fit of magnanimity, decided to bestow upon us mere mortals the gift of their superior LED technology. Down they flew from their mountaintop aerie, each carrying a pair of Super-Ultra-Bright (tm) Firefly-made LEDs in their little firefly feet, and upon reaching Belgium, they lightly dropped them into the hands of grateful research scientists.

I've done the visual beacon ID thing a few times. My CW skills are fairly poor, so sometimes that's the best way for me to ID a beacon. :-( I'm usually running MacLoggerDX and CocoaModem for RTTY and other HF modes (including CW), and the waterfall comes in handy.

You know about the CW skimmers, right? They digitize a chunk of spectrum, decode all the CW CQ's and callsigns and report them up to the mother ship. Sometimes helpful, oft abused.

I thought of another use, too. I'd like to have it monitor 50.250-50.280 or so for FSK441 meteor scatter signals. The possibilities are endless!

B. something that actually gathers the raw data.

I love and use that site and am subscribed to get alerts. The problem is that I get alerts for openings where I can't hear anything as well as no alert when there's an opening I can use. If I scan the SSB portions of those bands, I can tell when there's an opening at my QTH, and maybe even include an audio snippet in the email. I could also include what stations the cluster 'heard' in the freq that popped my local squelch. If I wanted to have my house look like a Navy ship, I could use a constantly-rotating antenna and include the azimuth of the signal. (or 'rotate' the antenna electronically; hummm......)

They are very cool and surprisingly capable. I had an initial bad experience (3 of 5 ordered from Newark were toast - the USB and ethernet would fail after several minutes), but they quickly replaced them with 3 good ones. I assume there was a bad batch in there somewhere.

It runs XBMC very well, and streams 1080 H.264 video just fine. I've also successfully used an RPi to decode ADSB transmissions from overhead aircraft using this software and an el-cheapo USB TV dongle. That's no small feat - the radio is pumping 2 Msps into that little fruity beast, and it's decoding them just fine. If you're curious, here's the source to the decoder app.
