I think that it would be good to have a breakout for HOPE RF’s RF90 NOAA Weather Radio IC…
I am currently kludging an micro together to send txts/tweets of the weather and would love to have a way to stream the clip to a device that is compact and small…

Does not look like it requires to much if any external parts… its a 3 x 3 mm QFN package which i have never had any experience with…
I also see a use for this to set weather warning beeps on amateur radio repeaters…

I like it. I’d be interested in one. I googled around just a bit, is anyone actually selling them?
not that I can see… I just hacked up an old radio that does not do same for interfacing with a micro and skype so I can listen to it when I am away from the radio…
Here is someone else who might be wants the same thing too…

I also would like a breakout board made for this type of IC. I found out that SiLabs has an receiver that outputs SAME and uses no external Crystal unless you want one. Strangely enough it looks like the foreign above copied the data sheet from Si Labs :lol:

Sure does. What's up with that?
prob a sham but I am with Kevin on this I have already coded some Processing and Python with skype4py (cool way to control the skype api… ) and it should skype out on a warning to my cell… would be nice to have something to control whatever in a warning …
Yes SI labs should be easy to get parts… Comeon 'ol sparky…!
I don’t know if this topic is still active or not. But after sparkfun released their SI-4735 AM/FM Receiver shield (DEV-10342) I took it upon myself one weekend to hack togeather a schematic for the si4707. Granted I haven’t done circuit design in over 10 years blows dust off his old Forest Mims books but I believe I’ve nailed everything necessary to get it up and running as a shield for arduino. SI has released the code for the si4707, and sparkfun has done an awesome job with their arduino code. So far the only problem is that the si4707 is a QFN, not just any QFN, but a very unique qfn that I can’t seem to get my hands on a protoboard to solder the qfn on. I found a company to purchase some si4707’s from, but both the ability to design a qfn protoboard with eagle, and eventually design the entire circuit in eagle is probably far beyond my ability at this time. I’m sure during the summer months between the kids, work, military, etc I could get it all down. Anyway’s, I’ve just come across this forum and if anyone is interested I’d be more than willing to put up a link to my schematic. Granted it’s not an eagle file, as I’m still old school and do all my work on graph paper.
Maybe I can get the collective group of people a heck of alot smarter than I am to get this done

A forum post has also been started with Ian at Dangerous Prototypes. We are stuck trying to find the parts to make them. I am sure they would be willing to design a board and a I am sure that it would be 100% open source.
So please if you can help us to I would love it.
