on the ground floor of Radio Town, in the very back, an android device booth popped up. Among the devices I saw there:
* Two variants of handheld android game consoles. One mimicked a PSP, down to the silver ring on the back of the disk cover (on Japan only PSPs). The other mimicked a large version of the Super Nintendo controller.
* A multitude of tablets, from ichiman to yonman.
* A few mini/pocket android devices including this one: http://dx.com/p/jxd-s18-4-3-resistive-screen-android-4-0-mini-pad-tab... Yep. The price was reflective! I think it was about 3800 yen... maybe 4800. Dont remember exactly. But damn cheap. Screen resolution is blah.. but it was meant to be a pocket video player/simple games system. Would be GREAT for a data collector (assuming your sensor talks USB or wifi),
* In fact, most of the devices they had on display were from JXD, and pretty cheap. I am thinking of picking up both a tablet (with hdmi, for school work) and a pocket device.. heck.. maybe even one of the gamer units just for kicks (although I have a PSP and have not played it since the last time I went to the US).

Well. My reply to http://usingimho.wordpress.com/2011/06/14/why-you-should-stay-away-fr... Would be that as all FOSS titanium is a work in progress. I tried titanium about a year ago and had trouble with running android programs. I came back to it a year later and it seems to be a much more mature project.
It was much easier than before to get everything working and it now even has an IDE which I think is eclipse. I think that that community is working hard to make it all work better.

Please keep a time slot free during my next visit to show me the place ;)
If some of the ultra-cheap tablets/pocket devices have a USB host interface
they would be very interesting to be hacked into one own project.
You couldn't get a cheaper way of displaying your data and having a great
touchscreen user interface for your project.
IMO, the android group at THS should focus how to get those ultracheap
units embedded in a project (connecting peripherals like arduinos, read
data via bluetooth/wifi from sensor nodes, etc.) Some of them might have
great hack potential providing some serial or SPI or I2C interfaces as well.

While they have their uses I often find hacking around with Android devices infuriating,
there are basically 3 reasons for this:
1. The kernels are often compiled with features missing (e.g. no ext3 support).
2. They use propriety drivers (e.g. PowerVR on OMAP3 devices).
3. They don't use glibc or any of the "normal" Linux userland utilities.
I've been playing with a MotoActv, the hardware is awesome, I've also got the system running
Debian after bootstrapping it with a statically compiled debootstrap. However the propriety
side of things is rather annoying. I can't use the graphics drivers from Debian because the
userland libs have been compiled against the propriety libc clone Android uses. And obviously
I can't compile my own, because sources are not available. The battery charging circuit is also
software controlled and propriety which is annoying.
Anyway, if your looking to write an Android app and have it control some supported hardware, I'm
sure that's fine. But if you're looking to embedded it into a device, I'd consider how the propriety
userland in Android is likely to effect you.
Yeah, I agree. My main reason for lusting after them was for using them as display heads for embedded devices. Its hard to find those units with bluetooth though. But now Xbee has a wifi module as well.. so.. hmmm.. Some of their devices have "USB on the go" which means it can act as either host or slave. Most of the host stuff is for memory stick, ethernet or 3G modules.. but maybe a driver can be written for host mode for android and FTDI.

From my understanding, queing a reprap isnt so practical. Theres still a lot of human interaction. You can start an long printing time object and go go bed, only to find it failed part way through.
Or worse, had a bind up but kept printing, leaving a mess all over the table.

One interesting idea would be a large scale 4-up device which has one movement over 4 beds, such that you may choose 1-4 copies at once. Only heater and feeder would be independant per head.
Were a bit off topic now. But android based 3D printing is a good idea. Android would make a decent head device for machining operations.
Bluetooth made headway in factory automation nets before the consumer market. Might be interesting to get a PLC and try building up a library for SCADA and HMI on android.
For the uninitiated, SCADA is supervisory control, while HMI is human to machine interface. These devices do not control machines themselves. They feed data based on user input (called a recipe) and monitor status and production for the front office. The PLC does all the actual work and manages safety of the machine. Thus, an RTOS is not usually necessary. In the case of full PLC replacement with a pc or smart device, the design of the os becomes much more critical.
