do you have some "motivational" examples of using this kind of board?

#22I got the MK808B for $48. It's a dual core 1GB PC with WIFI in the size of a thumb drive. It comes with Android and connects to TV via HMDI. Works pretty well as a Android TV device. Want to get another one to install Linux to play with it.

#23I got three of these. I need controllers like I need a hole in my head but hey, they are really really cute. A bit of trouble with the release that was on them but downloaded and burned in the latest and they were fine. Sadly no, I have not yet put them on a meter but will when they are near such a setup. Something that sets these apart from the Raspberry Pi are that they full of easy access I/O, and two the Cloud9 I…
Happy to see that these powerful little things are getting more affordable. What does those expansion pins do? Can they be used for I/O like button and LED?

#24So. We got so many of these products on the market. Why though?

#25I got Cubieboard. It's pretty much same specs and it has SATA. https://cubieboard.myshopify.com/collections/frontpage/produ...
Looks like the Cubieboard has nominally better specs - twice the RAM and NAND), but a couple things worth noting if people are looking to do electronics-type hacking:
* the Cubieboard comes w/ male headers for its I/O pins. This is a lot less convenient from a practical perspective. There's an additional baseboard you can get but it's huge or I guess you can put your own blocks on.
* the Beaglebone comes w/ two PRUs if you need to do real-time work this is pretty sweet
* For general I/O, libraries like PyBBIO and Bonescript make the Beaglebone dead simple to program with. As far as I can tell, to access GPIO for the Cubieboard, there's a custom kernel module driver you'll need to install to access via /sys and no clear docs on PWM or other "basic" stuff.
Also looks like right now, the Cubieboard is a lot less mature and it's unclear what the timeline is for it to get better - for example, looking at the Google Groups threads, looks like there's the VPU/GPU acceleration is a bit finicky (the Cubieboard uses Mali-400, Beaglebone uses SGX530, both closed source/binary only drivers). There also seems to be a pretty active contingent of... less than helpful people on a lot of threads.

I teach a beginning robotics class to local area kids. We were going to use RasPis this year but I could only get 2 of them (I needed about 10) so we ended up going with TP-Link WR703n's and arduinos instead. This actually ended up working better anyway with less hassle.
I'm hoping that BBB's (3B's?) are going to take their place in the fall. They seem much more suited to tinkering than raspis. A very exciting platform!

#27Got the Black delivered on my door today, will try to post a quickie review tomorrow :-)
Do you have a power meter by any miracle? The main advantage I see to this over the Raspberry Pi (for my application) is its spartan power usage.
The spec sheet[1] says power consumption is 210-460mA@5V (the rpi-B in comparison is specced at 700mA right?)

#28The impulse buying tech nerd within me sees a $45 computer with potential for being able to make anything and I am stuck for ideas as to what I could use this for. Does anyone have any suggestions?
My original Beaglebone has been stuck in a colo facility for a while now (18 months?) and has cost me about $20 of hosting fees so far.
The power consumption is stupidly low, the colo company had to find a different meter to measure it from their normal server oriented one.
I use it as a DNS server, and SSH tunnel destination.

If you can afford it, I would recommend buying one (or an Arduino or RasPi). Even if the most you ever do with it is run through some simple tutorials, it is still worth it. I have a few Arduino's and RasPi's, and to date, I have yet to make anything noteworthy, but going trough random tutorials has been fairly educational and entertaining.

Out of curiosity, where do you have it hosted?
