Nuts. I lost the Japaneses characters in the last item above. Apparently, it is  two friends talking about amateur radio in Japan. I don’t understand Japanese at all, but you can tell that they are having a lot of fun doing this video.

Contest encourages hams to develop microcontroller apps

From Luc, ON4ZI via the Linked In Amateur Radio Enthusiast group:

ON6NR starts the second Ham – mbed/ARM contest

Discover top notch microcontroller. Propose and describe a Ham application using mbed board see http://mbed.org. 10 projects ( described in French) will be selected and will receive an mbed module to realize the suggested project. Appropriately documented circuits (Doc or txt), with video (uTube) and/or pictures (jpeg) to prove affective functioning send by June 30th, 2012 will be entitled for the final draw with sponsor pricing to be defined.

The contest aims at 3 objectives: 1) Help Ham fellows to discover and experiment with “top notch” 32 bit microcontrollers; 2) Make their development useful to the ham community; 3) Generate quality articles to be published in QSP Revue, the freely monthly electronic publication issued for Hams at the radioclub (5000 + downloads, plenty of mirroring)

Submissions must be sent to either on5fm@uba.be or on5fm@dommel.be no later than 24:00 (GMT) 22nd April 2012. A jury of ham operators, embedded specialists and engineers will review proposals for concept quality, possibility of realization, reproducibility, interest and usability. It will not necessarily be the most impressive proposals that will be selected, so all participants have an opportunity to win!

The mbed microcontrollers are interesting in that they are 32-bit designs in a very small form factor. The entire microcontroller, including a USB port fits on a PC board the size of a 40-pin DIP!  By contrast, the Arduinos are all eight-bit processors.
