<rjeffries> from what wolfsprau1l has said in past Ingenic is n ot exactlt open to strathgers
<kristianpaul> rjeffries: come on, english is wellcome everywhere ;)
<rjeffries> I do not know anybody there and do not read/write Chinese
<rjeffries> I wonder what mass produced products there are that use 4760
<kristianpaul> may be 4760 will have built-in wlan rjeffries ;)
<kristianpaul> rjeffries: did you tried asking xbusrt (seriouslly, this questions are good to ask then)
<rjeffries> would a design simular to atben that was built0in to a future NN be able to use GPIOs rather than specifically the sfio stuff
<rjeffries> wpwrak just thinking is all
<rjeffries> isny 4760 dueal core?
<wpwrak> rjeffries: a lot more. the 4720 has 90. the 4760 has 168
<kristianpaul> rjeffries: are you interested on 4760 for some particular porpuse?
<rjeffries> will 4760 have more free gpios or about same as current chip
<rjeffries> wow the one day bump in visits to home page is cool
<wpwrak> rjeffries: even 3x if the manual is to be trusted
<rjeffries> wpwrak does 4760 support 2x 8:10 interfaces (I think ans is yes?)
<rjeffries> thx
<rjeffries> kristianpaul is there a description of your GPS project online? I am not sure if you are doing software defined radio for gps? or some hardware assist

2011-05-07

<rjeffries> mildly interesting
<rjeffries> wolfsprau1l what hardwrae is sed for your server. it is acrting hammered. a good problem to have,
<wpwrak> rjeffries: great, thanks !
<rjeffries> wpwrak I just pimped your VGA thingie on Identica and Google Buzz
<lekernel> rjeffries: as you can see on http://forums.winamp.com/forumdisplay.php?forumid=84 people actually manage to write these things
<kristianpaul> rjeffries: not so, people can do minor modification and learn/experiment from there
<rjeffries> dvdk the irc log seemed to be unreachable at first for me. then is mysteriously came to life
<rjeffries> kristianpaul wolfsprau1l making it relatively wasy for a milkymist user to create and modify patches using high level controls sounds like a genuine need
<rjeffries> waht is involved with creating a new patch for milkymist?
<kristianpaul> rjeffries: a bit of RTFM about milkydrop,
<rjeffries> wolfsprau1l "genetics of audiovisual" is a meaningless phrase.

<wpwrak> rjeffries: (usb) i agree with full size for a host port. that's what you need in the end anyway, so anything different just means that you have to carry a cable
<rjeffries> my "dream" next gen dev board (as precusror to something packaged in a slick fashion, would have full size USB.
<rjeffries> since sharism does not own tooling for current Ben case, to my mind a next gen Ben can and should use a new physical design for enclosure.
<rjeffries> DocScrutinizer although full size USB connector is bulky for a small device, to my knowledge none of the interesting add-ons such as wifi are offered with the micro USB or MiniUSB connector.
<DocScrutinizer> rjeffries: regarding this point I'm quite on same page
<rjeffries> but Iagree that ship has sailed, that train left the station. if next-ben does not offer a reasonably priced wifi connectivity option (can be plug in, via USB) then you miss any chance at a large enough market opportunity to be relevant
<rjeffries> ATben/ATusb are great stuff, but do not provide ubiquitous connectivity. thus they are not a single-ended solution, y
<rjeffries> as to wifi being too hard, virtually every current generation smartphone supportw wifi, and does so rather well.
<rjeffries> wolfspra1l have been reading your comments suggetsing wifi is not important. not sure why you have that opinion
<rjeffries> ristianpaul makine soft cheese is so easy. basically heat the milk to a certain temp, then stir in lemon juice. it will curdle (get lumpy) and then you strain through strainer of "cheesecloth" add salt. it is delightful
<rjeffries> spectec.com.tw seems to not be a public web page
<rjeffries> wolfspra1l just noticed numeric "1"in your irc name

2011-05-03

<rjeffries> clever stuff, lekernel
<wpwrak> rjeffries: (next dev) yeah, it's easier to sneak such a "devboard" in while making a new device.
<rjeffries> donning fireproof gear: the Ben keyboard sucks. period.
<rjeffries> Ben is a minimalist Linux system that is impressive in those terms
<rjeffries> well getting on the Internet is not a crazy desire. ;)
<rjeffries> s/sever/severe/
<rjeffries> as well they should be ;)
<LunaVorax_mini> I agree rjeffries !
<rjeffries> Ben's lack of host mode USB is a sever constratint
<rjeffries> LunaVorax where do you live if I might ask
<rjeffries> nice place !
<rjeffries> I could see a nice small market for a next gen Ingenic device similar to what you need, but with newer4760 SOC and more i/o
<rjeffries> well, that is an interesting point of view in that it is getting hard to find displays that support VGA
<LunaVorax_mini> I know rjeffries but I consider the Pandaboard being too sophisticated as it have DVI + HDMI while Composite and/or VGA is more than enough (and everyone doesn't necessarily have DVI/HDMI compatible devices)
<rjeffries> it had Ingenic SOC + FPGA and has a lot more capable i/o than Ben
<rjeffries> it eliminated the keyboard, but maintained a connector so the Ben LCD module could be attached
<rjeffries> the project that has faded that was in that direction was swiss army knife board later called SIE
<rjeffries> there are several pretty cool alternatives around. In addition to Hawkboard (a clone of Beagleboard as I recall) there is the newer Panda board that TI is backing
<rjeffries> LunaVorax Milkymist is super, but in a completely differnt class than Ben on multiple dimensions
<LunaVorax_mini> Yes rjeffries that's what I tried to say.
<rjeffries> yes about $500 now while Ben is nominally $100 + shipping
<wpwrak> LunaVorax_mini: (dangerous) ubb is fairly safe :) even if you short things, nothing breaks. things can be hacked without incurring excessive risk; don't listen to rjeffries ;-)
<rjeffries> kristianpaul I donated my UBB to the friend who temporarily loaned his Ben to me
<kristianpaul> rjeffries: you could help testing, you have UBB, i guess some time also to reproduce werner work at home and try with your monitor too.
<rjeffries> wpwrak lookinh ay your latest UBB/VGA results indicates Wolfspraul should start a program to copyleft (is that a verb??) the XEN-1510T monitor. Maybe bundle a monitor with each UBB VGA adapter?
<rjeffries> <smile>

2011-05-01

<rjeffries> lekernel thanks for suggesting I buy a Pandora gizmo. ;) I have not paid attention since the early days when they struggled do get a few built
<lekernel> (and rjeffries :p )
<wpwrak> in fact, i did the vga thingy because rjeffries was getting on my nerves with suggestions to use a prop for video output ;-)
<jirkab> rjeffries: I'm an active NanoNote user, too (jirkasnotes.wordpress.com). I use my NanoNote on daily basis ;-)
<wpwrak> rjeffries: imho, what the ben needs badly is a successor. alas, the successor needs financing. not a lot, as far as such things go, but still more than you probably carry around in your wallet
<rjeffries> wpwrak I agree re urgent need for Ben NN sucessor
<rjeffries> iit may well be that the future is more in the directing of your FPGA work. clearly that ius where wolfspraul is focusing
<rjeffries> lekernel fora product such as ben that should appeal most to geeks and techno nerds, the silence is deafening. Ben has not struck a nerve. in fact, one could argue it is on life support
<rjeffries> wolfspraul 's most recntlt released sales indicate maybe 1100-1200 Bens in the world. there may be at most 5o active users
<rjeffries> lekernel something we need to understand is why so many Nanonotes are what one might call "Drawer computers" or "shelf computers" i.e. NOT BEING USED AT ALL
<lekernel> rjeffries: is that significantly higher than with other tech products?
<wpwrak> rjeffries: unfortunately, not very detailed
<wpwrak> rjeffries: it has an SD interface. so you can use UBB plus a ribbon cable to connect. here's the data sheet: http://www.lsr.com/downloads/tiwi_r2/tiwi_r2_datasheet.pdf
<rjeffries> I saw that don't understand how it could be connected to the Ben 8:10 connector
<wpwrak> rjeffries: keep on going ;-) btw, the module without beaglestuff is here: http://www.mouser.com/ProductDetail/LS-Research/450-0037/?qs=sGAEpiMZZMuz9EkqwWgEDcRrleT5ZvLr
<wpwrak> rjeffries: that's the module plus some stuff you seem to need to interface to the beagleboard, yes
<rjeffries> is this the board? it is the $27 wifi module plus support circuitry  https://boardzoo.com/product_info.php?products_id=1
<wpwrak> rjeffries: no matter how far you have to go, the journey always starts with the first step ;-)
<rjeffries> but somebody in the community will.
<rjeffries> if a user is at a public location such as a library, or a coffee shop, or a waiting room, there will likely be wifi
<rjeffries> wpwrak that is as you know way WAY above my pay grade
<wpwrak> rjeffries: see above :) take the module, connect it, see how bad or good the driver situation is
<rjeffries> IMO if wifi was even an option for ben, it would significantly increase useability, and therefor broaden the maret
<rjeffries> wpwrak: there are a dozen or more mobile phones which support wifi yet have decent battery life.
<rjeffries> maybe LB in protecting their flank. android has some exposure to M$ patents it seems
<wpwrak> rjeffries: there's not much room for niche operating systems :) well, unless you're willing to pour large amounts of money into them.
<wpwrak> rjeffries: (cost calculation) yes, 3x is a low multiplier. however, there are a few special factors here: for some things, the entire R&D cost is "outsourced". second, we're competing price-wise with high-volume production. this means reduced margins or the product would seem excessively priced.
<rjeffries> kodein agree but one hope Meego can be at least a nuche mobile OS.

2011-04-30

<rjeffries> and would be applied to manufactured cost, including mfg overhead, typically 5-10 percent at teh higher end for small volume production
<rjeffries> s/mulriplier/multiplier
<rjeffries> wpwrak your mulriplier of 3x to arrive at selling price is on the low side
<rjeffries> This may turn out to be a postive development

2011-04-27

<wpwrak> rjeffries: (path of least resistance) means that building a kernel that works is a bit messy with ubuntu (or at last it was the last time i tried)
<wpwrak> rjeffries: (low duty cycle) you may find this document useful: http://datatracker.ietf.org/doc/draft-ietf-6lowpan-usecases/?include_text=1
<wpwrak> rjeffries: my workstation is running ubuntu. i haven't touched kernel support for atusb yet. (richard has written a skeleton driver, though. no idea what distro he uses.)
<rjeffries> wpwrak putting Ubuntu aside, what distro are you working with for ATusb?
<rjeffries> wpwrak I do not understand what this statement means, sorry... "the path of least resistance would be via upstream..."
<rjeffries> wpwrak I am not promotingAnt protocol. I do wonder how well 6LoWpan will perform as in environment where a node only needs to connect once or twice an hour
<wpwrak> rjeffries: (tuxbrain) he says he's very busy. i should have some more news from him soonish, though. (btw, i did mention this on the channel. you should stay logged in / read the logs :)
<wpwrak> rjeffries: (ant) sounds like a dead end, like so many "vendor standards" that perished when a proper standard came out
<rjeffries> wpwrak Nordic may use ANT http://en.wikipedia.org/wiki/ANT_(network)
<rjeffries> wpwrak what has to happen (once you have eveerything working) to be able to easily install ATusb code on Ubuntu
<rjeffries> wpwrak have you had any status at all from Tuxbrain re the fisrt manufacturing run? teh silence is deafening
<rjeffries> the beauty of the Nordic chip is very low power
<rjeffries> I have asked them about what license they use and about the Nordic chip
<rjeffries> I seem to remember in dim recesses that Nordic is doing their own thing
<wpwrak> rjeffries: also, IEEE 802.15.4 defined various PHYs. the most likely to be able to talk to others is the 2450 MHz O-QPSK PHY. (IEEE 802.15.4, 2450 MHz is enough to identify it. there are other 2450 MHz PHYs, but defined in other documents, 803.25.4a and such)
<wpwrak> rjeffries: the nordic stuff doesn't claim compatibility with anything
<rjeffries> agree
<rjeffries> the radios are all proprietary including ATben/ATusb
<rjeffries> I think the rest of his stuff is open a la Jee Labs
<wpwrak> rjeffries: wrong. atben/atusb is IEEE 802.15.4-compliant
<wpwrak> rjeffries: (nordic) sounds proprietary. that norduino page is also amazingly non-specific about any technical details
<rjeffries> but could you tell us how many Bens Sharism has shipped? As mentioned before, my gut feeling is that rate of sales is quite slow recently, based on no newbiews showing up on irc or mail list
<rjeffries> wolfspraul we have not had an update on Nanonote sales for quite a while. I realize you do not have data on sell-through by your distributors

2011-04-26

<rjeffries> wpwrak I have used godaddy to register domains, never had an issue
<wpwrak> rjeffries_: yeah, i'm already putting it to use :)
<rjeffries_> your right angle connector for connecting a scope (or anything else) to UBB looks useful
<rjeffries_> cool beans
<wpwrak> rjeffries_: you can still get the docs, though
<wpwrak> rjeffries_: they make you "register", but they don't require a valid e-mail address
<wpwrak> rjeffries_: yup
<rjeffries_> MMC association closed up shop and merged into JDEC  http://www.mmca.org/

2011-04-25

<wpwrak> rjeffries: maybe. if things go well, then i'll use mainly the MMC controller, so the CPU speed would be less important
<rjeffries> wpwrak when we have 4760 (it just a matter of time...;) will the increased CPU speed help with VGA hack?
<wpwrak> rjeffries: maybe they just plan to sit it out. tables have come and gone so many times before, expecting them to disappear after a while wouldn't be the worst conclusion to draw.
<wpwrak> rjeffries: nokia is now wed to M$, probably till death do them part
<rjeffries> I am amazed at the uptake of iPhone in China. many rich people I guess
<rjeffries> Intel so far is missing out on tablet wave
<rjeffries> yes indeed. nobody builds anything in quantity oustide of asia. sadly
<rjeffries> Nokia tablet that is NOT Microsoft would be a good idea IMO
<wpwrak> rjeffries: i'm pretty sure those 747 are national flights today :)
<rjeffries> as he put it, they were shipping a 747 worth of phone to China, per day
<rjeffries> IMO Nokia will make it, no question.  And they know how to manufacture in VERY high volume
<rjeffries> back in the day when I worked for Ericsson one person explained how crucial software quaity is
<wpwrak> rjeffries: of course, a drowning man will cling to anything :)
<wpwrak> rjeffries: trying to compete on low cost and high volume is a dangerous path for a high-overhead company like nokia. maybe they can beat apple, but they they're up to every single backyard CE fab in china. DVD players anyone ? ;-)
<rjeffries> s0rry for dupe
<rjeffries> wpwrak understood.
<rjeffries> maybe just maybe Nokia has a hold card vs. a vs. Microfoft and Windows Phone
<wpwrak> rjeffries: sure, you could have an external video generator. but that eliminates the simple beauty of the vga solution
<rjeffries> if the external widget has memory, copy our framebuffer to it, then all magic happens elsewehere
<rjeffries> wpwrak couldn't the clock originate external to Ben? (pardon my massive ignorance)
<wpwrak> rjeffries: i don't know HDMI. i would expect it to operate with a faster clock than what we can usefully provide
<rjeffries> by the way I contacted a guy who is close to the whole Propeller/Parallax stuff and he says teh follow-on will happen this year, will have new name
<rjeffries> actually... this takes me back to thoughts of external Propeller board. just a brain excercise is all
<rjeffries> wpwrak VGA is an analog display (I think) what parts would be required so (external to Ben) we have SPI input from Ben, and HDMI out (to display or TV)?
<rjeffries> I know tehre are several USB to dsiplay adapters a similar idea I think?
<wpwrak> rjeffries: monday may still be a holiday in spain (as it is in most of europe)
<rjeffries> somebody needs to alert tuxbrian that Easter holidays are complete. back to work! <grin>

<rjeffries> fascinating experiment. now I am off to bed. cu
<rjeffries> ah
<rjeffries> I will admit I would not choose to read War and Peace on that display
<rjeffries> amazing
<rjeffries> like an elephant that dances. amazing period
<rjeffries> oh now I see I missed it
<rjeffries> where is the link wpwrak?
<rjeffries> hang on
<rjeffries> all that matters to you is it costs you $39 and change
<rjeffries> (for thsi chip in this volume at this time)
<rjeffries> in fact it is a partnership bewteen desgn engineering and the manufactuter
<rjeffries> by the way in higher volumes yiedl belongs to the assembly house they make educated guess the first time the see a design, iuf the yield is crappy next time you pay more
<rjeffries> nods
<rjeffries> not as much as I thought
<rjeffries> bom is all I have to look at. I was only curious as to the FPGA I had no idea the price range
<rjeffries> yes prices drop a lot in volume
<rjeffries> buxiness guys are such a total pain in the you know what
<rjeffries> yes you have NO FEAR in terms of me
<rjeffries> understood
<rjeffries> in any case from my POV at current qty 1 price your margin is pretty thin
<rjeffries> ok the reason I asked was I did not see in on RC3 bom, thx
<rjeffries> wolfspraul is PCB 4 layer or more, and roughly what does it cost again in these modest quatities
<rjeffries> I am wondering what the FPGA chip in MM costs in the 100 qty sharism is buying
<rjeffries> ok then
<wpwrak> rjeffries: you may want to take a coffee. they're just a moment away ...
<rjeffries> wolfspraul agree the Milkymist article is Most Excellent. congrats!
<rjeffries> wpwrak I'll look for your screen photos tomorrow.
<rjeffries> we all learn and grow and change
<rjeffries> I am so old I remember when wolfspraul dismissed the idea of writing up Ben NN on wikipedia. ;)
<rjeffries> they got it right the FIRST time. amazing
<rjeffries> this is a VERY fun article about the 6502 design, and especially layout
<rjeffries> wpwrak so you can display something over SPI-->UBB..>[vga connector???]

2011-04-23

<rjeffries> wpwrak yjis Propeller dev board has a loy og available plu-in modules. fairly cheap.
<rjeffries> yes agree wpwrak. I do hope Propeller 2 sees the light of day however
<wpwrak> rjeffries: yeah, but some aspects of the thing carry a whiff of madness ;-) and of course, there's genius as well. they sometimes go hand in hand :)
<rjeffries> i meant to write one-man design effort
<rjeffries> s/mad/man but a funny typo
<wpwrak> rjeffries: similar to anything mp3
<rjeffries> wpwrak mayeb I;ll do some email sleuthing on lcc
<wpwrak> rjeffries: "not sell" probably means that you can't ship it with a ben in any form
<wpwrak> rjeffries: (one mad) indeed ;-)
<wpwrak> rjeffries: (prop 2) two people ? aw ... is parallax that small or have they basically abandoned the architecture ?
<rjeffries> nope the propller was as I remember a one mad design. prety amazing in my opinion
<rjeffries> yeah {ropeller 2 has been stalled. I think it is still being developed by one genius but oddball engineer and a smart layout person
<rjeffries> not sure that is what that licese means I read it that you can not SELL the LCC software
<rjeffries> lcc looks ok to me, but I am not a freedom taliban eiether http://en.wikipedia.org/wiki/LCC_(compiler)
<wpwrak> rjeffries: well, the problem with non-commercial licenses is that they conflict even with loss-making endeavors like ours
<wpwrak> rjeffries: okay, that's a decent enough start. afaik, LCC had an anti-commercial license, though. so that would be a problem.
<wpwrak> rjeffries: (c compiler) is it open source ?
<rjeffries> wpwrak I will check on that C compiler just forund out about it  recently
<wpwrak> rjeffries: for vga, consider using a cicuit like the prop uses with ubb. i'm not entirely sure if it could work, but it might
<rjeffries> wpwrak there is a C compiler ay long last not sure of code quality
<wpwrak> rjeffries: (prop) perhaps. don't know how much the prop can do in parallel. e.g., if one peripheral plus communication with the ben already eats up all the cogs, it's not worth the trouble. if it can indeed do a bunch of things, maybe.
<wpwrak> rjeffries: is there a decent free C compiler for the prop by now ?
<rjeffries> I winder if we could have an adequate VGA interface that way?
<rjeffries> wpwrak since Ben++ is a hazy future, Ben+ubb+simple Propeller boardwith putpose of adding i/o to Ben might work
<wpwrak> rjeffries: (atusb) yup. it's another thing with high setup cost but better per unit cost afterwards. less so than UBB, but still
<rjeffries> a hood thought experiment is what will stimulate demand for ATusb. that will drive unit vosts lower
<wpwrak> rjeffries: (prop) are you thinking of something like ben+ubb+prop or ben++ ?
<rjeffries> I think roh meant to not force the softwrae into distros
<rjeffries> yup. since it is Easter season, I am hoping for the resurection of Tuxbrain //bad joke, I know
<wpwrak> rjeffries: _forcing_ software intro distros may be much harder than you'd imagine ;-))
<rjeffries> wpwrak back to propeller-land for a moment one also gets keyboard, VGA video, mouse[ps2] and keyboard[ps2]
<wpwrak> roh: how could rjeffries forecefully bundle it if tuxbrain is selling the individual components ? :)
<roh> rjeffries: openwrt is just 'one' distro.. well.. in that case one optimized mostly for appliances and especially all these plastic routers
<rjeffries> s/oick/pick
<wpwrak> rjeffries: openwrt isn't really the main path. for kernel stuff, it's via netdev and then vanilla. trickles back down from there.
<roh> rjeffries: well.. yes.. but dont forcefully bundle it
<rjeffries> question: once the tools and drivers are in openwrt, how hard to get them into a distro such as oick one, Arch, Debian...
<rjeffries> roh that sounds promising about $50 USD in round numbers
<roh> rjeffries: openwrt-able plastic routers with usb start at something like 25E
<rjeffries> wpwrak yes a Linux PC will work, of course. but something really cheap and low power consumtion  that runs 24x7 would be nice
<roh> rjeffries: somebody should make sure the neccsary tools and drivers for the atusb get into openwrt
<wpwrak> rjeffries: admittedly one with the right drivers. but we'll get there as well :)
<wpwrak> rjeffries: the easiest way for Internet connectivity shall be to just plug an atusb into a linux pc :)
<rjeffries> wpwrak the propeller is as you know well a quirky chip... cool but quirky. yes  a smallock.
<rjeffries> lekernel uses a big (!) fpga I assume.
<wpwrak> rjeffries: dunno if the prop is worth the trouble. i like the concept, but wouldn't, say, a cpld or a small fpga serve us better ?
<rjeffries> wpwrak an OK way to get ethernet connectivity will be ATusb working on a cheap linux router
<rjeffries> wpwrak indeed, a combo ofIngenic SOC and Linux with Propeller chip as "helper" chip would give VGA, also a LOT of i/o it's cheap too.
<rjeffries> According to goo.gl 33 people clicked on my note today about Milkymist (across identi.ca, twitter and Buzz)

2011-04-22

<wpwrak> rjeffries: (ether) i think it's slowly dying. i'm a luddite myself, but i see less and less reason for putting up with wires. and outside the near confines of my lair, it's a wifi world anyway
<wpwrak> rjeffries: (ben as wpan console) sure, it can do that. but is plain 6lowpan enough ? or are there more stacks that need supporting ? i.e., what exactly do the things you envision it to talk to talk ?
<rjeffries> ATben ATUSB 802.15.4 which has reach of 10 meters or more, about 1 Megabit per secone, 6LoWpan protocol
<rjeffries> the board Carlos started (SIE, earlier called swiss army knife card) that married Ben SOC with an on-board FPGA and dumped the keybaord, but allowed for Ben LCD display and had USB host and Ethernet is close to what we could envision, but implmented with new Ingeninc SOC 4760 one assumes
<rjeffries> oh and with werner's radio stuff naturally
<rjeffries> yup
<rjeffries> LunaVox_mini that is what I am thinking. iT DOES NOT HAVE TO BE A CONSUMER ELECTRONICS DEVICE TO FIND A MARKET
<rjeffries> sorry for all caps mistake. d'oh
<rjeffries> larger makes sense. the usability of current keyboard is IMO poor (and I am being polite)
<rjeffries> that book is expensive $58 USD but I may buy it to learn more
<rjeffries> the idea of a nanonote (future) that supports a better keyboard that is also a little
<rjeffries> a bit more space while not going anywhere close to netbook size would work
<rjeffries> my thinking is that soem small compromises on formfactor to allow
<rjeffries> LunaVorax_mini I agree. wpwrak dislikes ethernet due to size of rj45 connector but it is a univaersal way to hook up to a router
<rjeffries> when I say Ben I really mean a followon that has the radio built-in
<rjeffries> he is working on a project where they use wireless at a station to exchange batteries for electric vehicles
<rjeffries> a while ago I talked with an engineering grad student at CalPoly a local college
<LunaVorax_mini> I was skeptical about the accuracy of this book  rjeffries... and then I saw that one of the author is a member of the Contiki OS. That's enough to convince me that the book isn't bullcrap
<rjeffries> wpwrak Ben could be a verty low cost potable terminal that talks to a collection of 6LoWpan devices
<wpwrak> rjeffries: how do you imagine it to be a target market ?
<rjeffries> This looks like a good book on "Internet of Things" which I claim (humble as always) may be a solid target market for a future Nanonote with integrated 802.15.4 6LoWpan radio
<rjeffries__> when teh phone radio is not active, battery life is amazing
<rjeffries__> I did not keep track, but it has run several weeks now, I'd say will over a month
<rjeffries__> I have a Palm Treo that is still running (although I am not actively using iy)
<rjeffries__> 32 GB
<rjeffries__> no I am asking wonder also if 3GB is ok
<rjeffries__> do 16 GB mem cards work with Ben now?
<rjeffries__> nods
<rjeffries__> would you like to get rid of NAND
<wpwrak> rjeffries__: ideally, two 8:10 for whatever use. the internal one typically with a memory card, the external one possibly with UBB and friends. the internal one should be placed such that peripherals would protrude into the battery space, so that one has the option of mounting something larger, even if only temporarily
<rjeffries__> yupos be damned
<rjeffries__> typos
<rjeffries__> i think i understand
<wpwrak> rjeffries__: as a fixed internal subsystem
<rjeffries__> relayed" why to just build the AR86RF231 and antenna etc on main pcn
<rjeffries__> so the second 8:10 would be for... memory card
<rjeffries__> wpwrak if there wre a next Nanonote, you see ATben as ain internal plugin, I suspect?
<wpwrak> rjeffries__: you're correct. the chip only does 2.4 GHz. IEEE have specified a fairly large number of PHYs for 802.15.4, some in 802.15.4-2003 and -2006, some in 802.15.4a, etc.
