Is this watch available for sale? I am thinking one day we just have to think and thought can be sensed and converted to an action.

Yes, this has been available in the market for some time now. 

I actually find it fascinating...after all, people have appetite for a watch which looks like a watch; but not so much for "wearables" which try to be a smartphone/watch on a wrist.

yeah, that is a peculiar observation. I wonder if it just has to do with familiarity?

@caleb, exactly. Familiarity is everything when it comes to consumers' purchasing decision -- unless whatever the thing is phenomenally convenient or useful. Wearable devices today are neither.

I think the most useful and interesting aspect of this show was all of the energy harvesting devices. These can be used in any number of applications.

@Patk0317, I agree. By using battery-less solutions, suddenly many of those IoT modules can go into so many different places.

Changes in the Japanese electronics industry

Both subtle and big changes were palatable at ET2013 show this year -- among Japanese vendors' booths.

They are more open and willing to pitch solutions they had not developed themselves. It almost looks like they have finally realized that they don't have to invent everything before they go to the market!

Oh!  Sorry that we missed you last week!  Space Codesign was exhibiting at EDS Fair (combined with ET) as part of our Asian distributor, Avant Technology.  We would have loved to give you a demo of our SpaceStudio ESL hardware/software co-design EDA tool.  We had a great reception among Japanese companies for our debut, as Japan is arguably the one of the most advanced C-based hardware and systems market on the planet.

Personally, it was my first time in Japan (after all these years, after all those air miles!) and it will definitely not be my last ... :)

@garydpdx, sorry I missed you too! Glad to hear that you got a good traction among Japanese companies. Let's synchronize our watch -- next time -- when we travel that far!

Has anyone used Ruby, object-oriented programming language (open sourced)? Now that 'mruby' for embedded is coming up, as shown in this slideshow, I'd like to get your feedback.

Junko,

Most students use python for programming Raspberry Pi. However, I will start asking the question as I visit universities on an almost weekly basis. I am sure someone is using mruby.

@Patk0317, thanks! I look forward to your discovery...I believe that mruby is still too new, but if indeed it can fit in such a small footprint memory as they claim, I think it could be interesting...

@Junko

I don't know mruby specifically, there were plenty of attempts to get scripting languages for microcontrollers.they largely failed because they need more memory, they really slow the code , they dont support real time code, and the general conservativeness of developers.on that note , even even inventor of Ruby thinks most embedded code will be in c/c++ not mruby.

on the other hand spansion can create microcontrollers in 40nm ,which might change the game.and them pushing mruby could certainly help.

and there is the new "micro python" which claim to solved the speed and real-time issue.we'll see after it's kickstarter ends.

@Junko,

Another option regarding mruby: ruby is popular in japan(for general programming). Maybe spansion want to improve prototyping of embedded systems in japan, and grow the maker community there. It makes sense since japanese companies buy more japanese micro's.

BTW: how's the maker community in japan?

@alex_m1, thank you. The Spansion angle you pointed out is an interesting one. Now that former Fujitsu Semi's microcontroller business is a part of Spansion, Spansion has a vested interest in promoting mruby. 

I hear the maker community in Japan is actually growing strong. I haven't had a chance to investigate more first hand, but that's what I hear from my colleagues working at EE times Japan.

I had not heard of this one. Does it have legs?

@rick, this one has legs. Echonet is something the Japanese ministry and the industry are promoting together -- thus giving more confidence among technology suppliers to move ahead with IoT in Japan.

Here's more info. on Echonet:

Definitely worth looking into.
