News - The Edison is Not a Raspb…
about 7 months ago
I didn’t miss … I was just objecting to dismissing the solution of a more powerful platform by equating it to something very very limited … hense the quote I was objecting to.
I made the point that this additional capability greatly advances applications past the limits of Arduino, so much so, that they are hardly equivalent.
Actually for most applications, other than collision avoidance for high velocity autonomous vehicles, a few FPS is all that is needed to integrate object detection/avoidance and to provide realtime GPS/inertial location/heading corrections.
And interestingly enough, also allows similar processing across multiple location/heading ultrasonic range finder samples to construct 2D/3D object maps using techniques similar to ultrasound/MRI.
Plus odometry from multiple environment sensors.
That is a HUGE leap forward over what an 8MHz Aurdino is going to do.
That’s where breakout boards come to play, and the whole Arduino wrapper to allow exisiting low pin density shields.
The 0.4mm pitch connector is slightly painful … but easily done with a temp controlled hot plate and hand stencils. Or by dragging a large solder ball across the highly fluxed pads with an iron, tacking with a precision iron and stereo microscope, and reflowing in a table top oven or on a hot plate.
I’ve been doing high density FPGA BGA’s that way for more than 10 years. Not your normal less than electronic tech skills … but this world has MANY hobbiests that can easily learn to take on more difficult projects … including many retired industry Techs and Engineers. I’ve shown high school robotics kids how to do it in my kitchen, including reballing FPGA’s and other chips, like are necessary for repairing gaming systems.
Thinking too fast … High resolution stereolithography for 3D printer robots, and Stereo Vision Processing for ground based intelligent autonomous vehicle robots and flying drones/UAV systems.
The Edison is really meant for applications where you’d use a traditional micro-controller like an Arduino
Absolutely NOT …. Edison finally breaks us away from 8MHz and 32K of ram, with a tiny amount of program space.
Edison with dual core and SSE2 vector allows realtime computation of video and high rate sensor integration, that you CAN NOT do with a dozen Arduino’s. It has the DDR3 ram and flash storage to build flight controllers that have high resolution maps, that you simply CAN NOT implement with an Arudino 8 bit toy processor.
Edison has the computational power to implement Stereolithography in robots and flight controllers that is way out of reach for an 8 bit Arduino … way out of reach for a dozen Arduino’s.
Edison is the new building block for building REAL automous robots …. Arduino is the building block for building toy training robots for novices.
And this is just the beginning of MANY important doors that products like Edison will allow people to build, that simply CAN NOT be built with Arduino.
When I put this into perspective, the BT interacts with your phone and your personal/room sound systems …. full audio.
With products like Google Glass redefining the UI … HID is no long about the computational engine, it’s about the sensory intergration external to comput.
Edison wins …. fast enough dual core plus vector instructions, LOTS of DDR3 ram and flash …. and LOTS of IO’s to attach other “smart” peripherals, and leave the dumb ones behind.
USB is Edisons systems level bus … to SSD drives, to Camera’s, to LOTS of high performance peripherials …. one HOST port into a 7 port HUB and what can you not connect in this world?
But really, your typical robot doens’t need BT and wifi , and often neither.
Actually your typical robot does need some non-teathered controller for human training and piloting. While some try that with IR remotes, that’s a crock … running it from an ap on your smart phones is far more practical, just like some of the more fun quad copters.
Tutorial - The FCC and Open Source Hardware
about 2 years ago
The pdf version is much more readable
Not everything with an FCC ID on it is even really legal, especially if it’s also marked “Made in China”, and sold on eBay.
See page 9: http://transition.fcc.gov/Bureaus/Engineering_Technology/Documents/bulletins/oet62/oet62rev.pdf
This last week I had interest in upgrading my old Motorola Backflip to a newer android phone, preferably with multiple cores (2-4) above 1ghz, 1gb ddr3, 4gb of nand, and a 5" or larger high res screen/digiitizer. Things like this selling in the US from “real” vendors, tend to be priced well above $600.
Very nice quad core MTK6589 Star S7189 for $189 are very tempting, except for the lack of a FCC ID. Some of China phones carry a fake FCC ID, like the Note2 series with an fcc id of A3LNote2, which isn’t actually a real Samsung in the database. Take a look at the pictures in the battery bay of China phones on eBay, until you find an FCC ID, then try and look it up. Just for grins, also lookup the IMEI number … for some phones both the FCC ID and IMEI numbers are counterfeit.
Look at the battery bay picture of this phone, with both a fake FCC ID and IMEI: http://www.ebay.com/itm/200927057435
The IMEI belongs to an Eiroga E71i which is a keyboard phone, and the FCC ID vendor is Samsung.
While this probably helps them get through customs without forfeiture, it’s certainly not going to protect the idiots reselling them in the USA from the FCC without filling the required 740 form, and hoping someone doesn’t check the FCC ID. http://transition.fcc.gov/Forms/Form740/740.pdf
The eBay China sellers when pressed, first they say they are legal, and they have a lot of resellers importing the phones.
Just like they don’t have a problem with counterfeit name brands, they don’t have a problem with counterfeit FCC ID’s. Press them a little harder, and you might get the following reply like I did :)
i understand your mean!
we also sell the model!
all china phone come with FCC mark on label!
our phone also come with it!!
but these phones only have the mark, but no test by FCC
if you think it is no problem,we can supply these phones!
So at the end of the day, it’s pretty hard to trust legal operation of anything from China.
No public wish lists :(
