The Chief Cat died today after battling kidney and heart disease. A fine cat, brave to the end.

Ireland
I was here for the CISDR workshop. The work shop went well, which should make Chris happy. (One of the work shop goals was to help Chris get tenure). I met a lot of new people at the workshop and we had some good discussions on future research ideas in SDR. Hopefully, some joint projects come from the workshop.
Ireland is a nice sunny place (the locals do not think the weather has been normal this week). Yesterday, I did the cliff walk from Greystones to Bray. I had trouble finding the beginning of the walk in Greystones, so I ended up walking several kilometers on roads and finally bushwacked to a summit above the cliff walk. The view was good and I managed to re-join the cliff walk proper.
While wandering lost I saw a lot of nice houses. Greystones seems to be a pretty upscale area.
The food is good, however the meat centric nature of the diet is getting to me. It's been good to find things like sausage rolls and Cornish pasties again.
Well, time to catch the train to the bus to the airport.

Travel Plans
I'll be in Ireland next attending the First Collaborative International Software-defined Radio Workshop.
We received a small grant from the National Science Foundation to cover our travel expenses for the workshop. Internally, the group working on the proposal called this the "Ireland Pub Crawl" project. In spite of this, we have a good program and it looks like it will be well attended.
Hopefully, I can get my Beagle Board running with a couple of simple SDR demonstrations and attract some people interested in using this board for SDR.

The cat is not helping
Sorry about the complete break down in blogging. Not much interesting to blog about. I really should say more about the FOSDEM trip, but that is old news. If I get somewhere with the Lyrtech Small Form Factor SDR board, I'll talk a little about that.
I like our cats more than I like most people, but at least people don't do this to me:

Gumstix mounting solution
Mt friend Hasan's PHD project is the build a flexible RF front end for public safety radio's. In the US (and I suspect many other countries) public safety radios operate on a diverse set of frequencies. This creates problem for people trying to design radios that can operate of the range of services using these frequencies.
Hasan is working on a RF front to solve some of these problems. As part of this work he is build a demonstration unit that operates on several different frequencies. There are several parts of the radio that need configuration information via a SPI interface. He is using a gumstix computer to do the control and user interface.
Here is an overall picture of the unit. Since it is based on evaluation boards, it seems kind of large for a handheld unit. I'm certain that professionals could create a compact unit based on his work.
Here is a photo of the gumstis mounted on the front plate and the LCD touchscreen panel used to change the operating frequency.
Finally, a side view to give you an idea of how the gumstix is attached. He used a threaded rod to stack the gumstix boards and attach them to the plexiglass.
