<wolfspraul>
I continued to write up your news items, it's shaping up very nicely
<akiwiguy>
Good afternoon, everyone
<wolfspraul>
I have the FISL talk, packageology, anatomy of a datasheet, ben-wpan production and testing documentation (WOW IS THIS GOOD! I didn't read it in detail before!)
<wolfspraul>
free cad tool comparison
<wolfspraul>
akiwiguy: hi kiwi guy :-)
<akiwiguy>
xD
<akiwiguy>
hai thar, wolfspraul
<wolfspraul>
wpwrak: I'll let you know when it's fully cleaned up. THen I will dig the mailing list archives to see whether there's more.
<wolfspraul>
finally I need to rearrange this whole giant mess of a page I have right now (08-01 news)
<wolfspraul>
as you can imagine I disagree with the entire analysis and conclusion of that article you link to
<wolfspraul>
we do share 0x20B7 with any Qi project
<wolfspraul>
welcome to the 21st century
<wolfspraul>
sometimes some leadership is required
<wolfspraul>
I am sure the USB forum is an honorable organization.
<wolfspraul>
most Chinese vendors wouldn't even bother to spell their name right, and randomly pick any number between 0x0000 and 0xFFFF
<wolfspraul>
and they serve the world with their products...
<wolfspraul>
it's a wonderful opportunity for the USB forum to come clean. I am openly saying: Qi paid 2000 USD for 0x20B7, and it's shared for any Qi project, and properly accounted for on our Wiki :-)
<wolfspraul>
and one important feature of our wiki is that anonymous edits are possible
<wolfspraul>
isn't that a wonderful world?
<wolfspraul>
Qi has solved the '2000 USD tax' those guys seem to have found.
<wolfspraul>
there are many more such taxes btw. I decided to pay 2000 USD of my own money to the USB forum because I think it's an honorable organization.
<wolfspraul>
I would not pay 4000 USD / yr to get a "SD host license"
<rejon>
hahaha
<wolfspraul>
that why Qi created the 8:10 standard
<rejon>
you guys talking again
<rejon>
geez
<rejon>
work to be done!
<wolfspraul>
rejon: well, he's right. Many people see those taxes and ask how it related to 'open hardware'
<wolfspraul>
Qi has solved the problem for USB (0x20B7), and for IEEE OUI (10-E2-D5)
<wolfspraul>
whether people accept or like our solution is up to them
<wolfspraul>
SD host license is a scam, we created 8:10
<wolfspraul>
MP3, no need to talk about it
<wolfspraul>
HDMI, same
<wolfspraul>
what else?
<wolfspraul>
rejon: the article says (let's assume this is authentic) "Anyone who wants to manufacture an UNO clone has to cough up $2000 bucks to get their own ID, Arduino cant share theirs. Thats the $2000 USB tax."
<wolfspraul>
I disagree. "Arduino can't share theirs"
<wolfspraul>
They dont' want to share theirs
<wolfspraul>
they don't want to take risks, because they don't care
<wolfspraul>
(about that case)
<wolfspraul>
thousands of Chinese companies that are very real can share theirs :-)
<wolfspraul>
rjeffries: you can write a letter to the USB forum and point to the Qi wiki page saying that Qi shared the vendor code it acquired with all subprojects
<wolfspraul>
see what they say :-)
<wolfspraul>
problem solved, for me
<rejon>
hahaha
<wolfspraul>
rejon: the article Ron linked to mentioned some 'dutch guys' (no url) who seemingly had their vendor id 'revoked' after trying to share it
<rjeffries>
rejon and wolfspraul I read the articel, found it interesting. Absolutely no aspersions intended.
<wolfspraul>
and it says that the usb forum is "getting more strict"
<wolfspraul>
rjeffries: no it's good :-)
<wolfspraul>
so...
<rjeffries>
I have ZERO interest in writing the USB Forum. why would you say something like that
<wolfspraul>
why not? help the Qi community
<wolfspraul>
I am trying to find little tasks for you :-)
<rjeffries>
I am interested more for a company I am working with that is all.
<wolfspraul>
if the USB forum 'revokes' the Qi vendor ID, as per their policies it seems they will not reissue 0x20B7
<rjeffries>
wolfspraul I am quite busty, but thanks again. ;)
<wolfspraul>
no worries my expectations weren't disappointed
<rjeffries>
$2000 is not a huge sum in a comercial enterprise
<rjeffries>
but still they whine
<wolfspraul>
it looks out many small and honest people
<wolfspraul>
maybe that combination can also just be called 'stupid' though
<wolfspraul>
the not so honest would just ignore this entire topic and produce and sell wahtever they want, with whatever random number that crosses their mind first
<wolfspraul>
or the number of some other company so the driver works
<wolfspraul>
so let me just summarize for the archives
<wolfspraul>
if the USB forum revokes the Qi ID and how we use them, I will publish any and all communication I receive from them
<wolfspraul>
after that we will replace the USB standard with our own, similar to the 8:10 standard for removable memory cards
<wolfspraul>
and done
<wolfspraul>
no end user will be affected by any of this, I'm pretty sure our post-USB devices will work quite well still. We will do a lot of testing.
<wolfspraul>
hope this makes sense :-) rjeffries thanks for bringing it up!
<rjeffries>
understood, although not a topic that is intersting to me. I asked a simple question, and now I know. and thank you
<rjeffries>
and a special thank you to rejon. I can always count on him for a bit of amusement
<wolfspraul>
rjeffries: oh btw, you have to pay more if you want to use some of their logos
<`antonio`>
i'll have a look and see if I can get some hints from the video on the wiki
<kristianpaul>
what hints are you looking for?
<kristianpaul>
feel free to ask i guess :)
<kristianpaul>
had you alredy look at mail list archives?
<kristianpaul>
i think werner wrote some interesting reports there
<`antonio`>
yes few of those are really helpful
<`antonio`>
ok, thanks !
<wpwrak>
catching up with a bit of backlog ...
<wpwrak>
kristianpaul: (wtf accum int.png) that could be some RF interference. e.g., if the pin is driven low and then Z. maybe it's not the FPGA pin but its configuration. or maybe the "pull up" transistor is dead :)
<wpwrak>
Ayla: you called ?
<wpwrak>
wolfspraul: (testing doc) glad you like them ;-)
<Ayla>
wpwrak: I did
<Ayla>
I heard you are mister Lilo?
<Ayla>
at some point we'd like to be able to install linux on the dingoo A320
<Ayla>
on the NAND
<Ayla>
so far, I was able to install the filesystem on the NAND with a UBIFS filesystem
<Ayla>
it works good as long as I boot the linux kernel through USB with jzboot
<Ayla>
do you have any advices on the way to proceed?
<Ayla>
maybe we can get uboot to start off UBI
<wpwrak>
hmm, i don't know if uboot supports ubifs
<Ayla>
I was also thinking about making a much simpler JZ bootloader
<wpwrak>
what i would do: write a very very very simple NAND loader that does nothing but a sequential load starting at page 0 (or 1), with the only exception being that it can skip bad blocks (you need that with NAND)
<wpwrak>
and the load a linux kernel with an initramfs, which then kexecs your real system
<wpwrak>
there, you can do anything you please. you have the full power of linux at your hands.
<wpwrak>
no need to mess with silly little u-boot :)
<Ayla>
yep, we were thinking about kexecboot
<Ayla>
so the first-stage bootloader would have full UBI support?
<wpwrak>
`antonio`: the setup is still a little bumpy. if you want to use the IEEE 802.15.4 kernel drivers, you need to build the ben-wpan branch of qi-kernel. then you can write native IEEE 802.15.4 applications or you can also use a bit of IPv4 via dirtpan
<wpwrak>
`antonio`: if you don't need IEEE 802.15.4, you could also use a lower level, similar to what the user-space tools do
<`antonio`>
i just want to try something simple with dirtpan
<`antonio`>
anyway I'll try and I'll let you know how that goes and if I am stuck, thanks !
<wpwrak>
Ayla: no, it would just do setup_memory(); p = LOAD_ADDRESS; page = 1; /* assume page 0 contains the boot loader */ do
<wpwrak>
if (!(page & (PAGES_PER_BLOCK-1))) while (nand_block_is_bad(page)) page += PAGES_PER_BLOCK;
<wpwrak>
read_nand_page(p, page); p += PAGES_SIZE; page++; } while (not_done());
<wpwrak>
((void (*)(void)) LOAD_ADDRESS)();
<wpwrak>
add a { after the "do"
<Ayla>
so, you just wrote the bootloader? :)
<wpwrak>
"not_done" would depend on how you express the end. could be hard-coded in the first block (so you'd replace the first block each time you update the boot loader). or you could have some end marker, either in the data (e.g., a page that's all zero) or in the OOB data (tricky)
<wpwrak>
yeah. that's all the boot loader you need ;-) (the functions it calls are a bit more work, though. also note that read_nand_page should do ECC correction :)
<wpwrak>
`antonio`: dirtpan currently doesn't handle traffic-intensive connections well, because the underlying IEEE 802.15.4 stack doesn't to proper CDMA, so eventually both sides fight "forever" for the right to send. i have a driver in the works hat will solve this for atusb, later for atben. need to put a bit more time into this, though. been slacking the last two weeks :)
<`antonio`>
ok!
<larsc>
the bootloader should also initalize pin and clock config
<larsc>
and mem
<Ayla>
larsc, indeed
<Ayla>
larsc: wait, does uboot actually does that?
<Ayla>
if we start a linux kernel, it won't be done by the kernel itself?
<larsc>
some of it is done by uboot some of it is done by the kernel
<wolfspraul>
wpwrak: like them [testing documentation] you bet. not just like it, it's truly fantastic
<wolfspraul>
we don't have much time or reason for celebration, but afaik this is the gold standard in how a good copyleft production documentation should look like
<wolfspraul>
I didn't notice it before, but finally I think I know why the production and yield of the boards at tuxbrain went so smooth :-)
<wolfspraul>
I always wanted to have something like this for the Ben, or now M1, but we never got our act together to get it into such a concise and focused format as you did with ben-wpan
<wolfspraul>
wpwrak: so in terms of completion, anything I overlooked?
<wolfspraul>
I think next step is to rearrange everything, make it lighter and more readable
<wolfspraul>
if the page is even still browsable to you :-)
<rjeffr>
it would be interesting for Zigduino to be an endpoint for wprak's ATben or ATusb.
<Ayla>
can two ATben communicate together without a ATusb?
<[g2]>
wpwrak, the arduino part is meant to be a "DIT - Do it Together" kinda project with lots of spins.  I'm thinking about possibly weekly PCBs
<rjeffr>
Ziguino is a bit pricey at $70USD, but not outrageous IMO. There is aguy working on a lower cost 802.15.4 thingie
<wpwrak>
roh: form factor ?
<rjeffr>
oh I thik his handle is [g2] LOL
<[g2]>
rjeffr, Hi... Outrageous :)
<rjeffr>
[g2] I like your style. you go, man
<wpwrak>
Ayla: sure. atben to atben, atusb to atusb, atusb to atusb, it's all the same :)
<rjeffr>
hello wpwrak I have been out of the loop. what is working so far at a simple level with your two modules
<wpwrak>
[g2]: weekly may be a bit excessive ;-) but yes, a (comparably) high rate makes a lot of sense
<roh>
wpwrak: arduino compatible means a constant formfactor anyhow. else its not compatible.
<[g2]>
wpwrak, I don't mean just by myself.  As my nick handles shows I was a dev on nslu2-linux..  We had 120+ devs in 2005ish time frame.  There were 6K+ people on the mailing list. I'm sure the communities are much larger now. IMHO
<wpwrak>
rjeffr: ieee 802.15.4 kernel drivers are now there. atusb still has high latency (due to protocol issues on the usb end), and neither implements cdma/acks so far (that's an issue inherited from upstream)
<Ayla>
wpwrak: ok, that's nice. If we install linux on the NAND of the A320, I wouldn't mind having a wireless card for networking or multiplayer
<rjeffr>
roh wpwrak well, Arduino can be defined that way, as in all sheilds must fit. some people relax that phsical form factor sucessfully
<wpwrak>
roh: well, i'll let the arduinites explain the concept :)
<roh>
rjeffr: yes. but it generates a lot of misunderstandings with not that technical knowing people and thats bad and generates bad vibes.
<rjeffr>
wpwrak I have zero idea what you and others will need to do for your 802.15.4 driver to be incuded in upsteam linux distros.
<roh>
besides that.. its not really big even if done correctly.
<stefan_schmidt>
wpwrak: auto ack and resubmit are still on my agenda for at86rf230. Should come withinj the next to months...
<roh>
the power source is usually much bigger than the arduino board or the rest of the electronics
<rjeffr>
roh I agree. I did order qty 5 of the little Femtoduino yesterday. I have contacted a shop locally who I think will do the SMT for at a very reasonable price
<rjeffr>
roh true, other than a battery fed system
<rjeffr>
in any case, i have a funny little bullshit use case where small is good
<roh>
rjeffr: even batteries are bigger than the boards ;)
<wpwrak>
stefan_schmidt: i'll probably beat you to it :) when i redo the atusb driver to overcome the protocol inefficiency, i'll also switch on cdma and ack. should actually be pretty simple.
<roh>
i am not against small. i am against starting there.
<wpwrak>
rjeffries: (include upstream) push and wait ;-)
<stefan_schmidt>
wpwrak: that would obviously be fine with me :P
<roh>
normal arduino users are BEGINNERS. means also for soldering etc.
<[g2]>
roh, rjeffries define small if you can
<wpwrak>
roh: (size) make it work with button cells ;-)
<rjeffries>
roh very true. nbodt is forced to purchase the smaller arduio-like pcbs. ;)
<roh>
so do not make it more complicated than it absolutely needed.
<stefan_schmidt>
wpwrak: (driver rewrite) happy with the firmware side now?
<roh>
wpwrak: button cells are ecological nightmares. dont use them.
<rjeffries>
[g2] my bullshit use case is a computer attached to a walking stick that will control a string of LEDs to make the walker (that would be me) safer at dusk
<roh>
maybe it makes more sense to make a atrf extension board
<rjeffries>
roh I think I'll use an AA form factor cell eiether n=1 or maybe n=2 recahrgeable naturally
<roh>
basically the chip and its crystal with the antenna on a pcb, to be connected via spi to stuff like a arduino nano etc.
<roh>
for the people who need a smaller formfactor
<rjeffries>
to be clear my walking stick MCU is not wireless. sorry if I confused anyone
<roh>
and to make it cheaper
<[g2]>
rjeffries, my current arduino board is only about 2x the size of the Femto or 0.82" x 1.42"
<wpwrak>
roh: heh, you'll love one of my secret little projects then. eats cr2032 like there's no tomorrow ;-)
<[g2]>
I was going go down to .07"
<rjeffries>
roh that is a good idea. but if [g2] can have an atmel MCU on that little board, the whole thing is smakll and cheap and can have some sensor inputs
<roh>
wpwrak: i know enough electronics which does... quite a waste
<rjeffries>
[g2] when do you get fabbed PCBs back?
<[g2]>
I've already have a version back
<roh>
rjeffries: it will be less flexible and maybe more expensive due to lower sold volume.
<[g2]>
s/have/got/
<rjeffries>
wpwrak what secret little project Sir Werner? Do tell.
<roh>
rjeffries: if there isnt already a breakout board, start there. there are lods of mcu out there and not everbody uses avrs
<rjeffries>
roh it will be dirt cheap however. the Femtoduino PCBs are available for $2 each including shipping in USA
<roh>
and us shipping is only a small part of this planet
<rjeffries>
roh I am not promoting it. it is merely something real cheap that I will play (repeat PLAY) with for my walking stick control system ;)
<rjeffries>
roh I get it. relax. actually teh guy will shiup via surface mail elsewhere VEY cheaply
<rjeffries>
this PCBs themselves are just under $1 and the bag of parts is about $7
<roh>
sure. i am just saying that i do arduino compatiple stuff.. but ive never bought an actual one.
<roh>
i just use the next best avr in my box
<roh>
if i need more than one pcb maybe i route one and mill it at friends or maybe on our mill (when its finally done)
<roh>
rjeffries: will he sell completed boards (machine placed)?
<rjeffries>
roh he does not but I am investigating that. it is so few parts that my small show may not use picj and place, but I do not have a quoute yet.
<wpwrak>
stefan_schmidt: (fw) it'll probably change some more once i start debugging the driver. i like the general architecture of the new features, though. oh, and eventually, i should kick out some of the requests. we don't really need two sets that do the same (reg/buf vs. spi) :)
<roh>
rjeffries: heh.. well.. tell me a price for them if you know
<rjeffries>
there is a hackerspace about 80 miles away and I know those guys. They bought a machine (cupcake, I think) which is a low end 3d fab machine
<roh>
currently it seems cheaper making some including pcb in europe than shipping from the us and hand placing
<rjeffries>
I don't think they have a CNC mill yet.
<stefan_schmidt>
wpwrak: sure, we can keep an older fw around until the new one is stable and then switch over
<rjeffries>
you may be right. hard to say.
<roh>
3d printers and mills dont really help for picknplace. sadly
<roh>
and the board seems to small to be milled properly (atleast if it shouldnt be pain soldering afterwards
<rjeffries>
oh I understand that. ;) I was merely saying we have a hackerspace. I have  not joined because it is so far away. I think I can get access now and again for a reasonable fee
<wpwrak>
rjeffries: the illuminated walking stick sounds nice. add color, and you can dual-use it as a light saber ;-)
<rjeffries>
roh agree Femtoduino is not a good candidate for cnc milling in lieu of regualt etching
<rjeffries>
wpwrak I make thes esticks from ranfom pieces of actual sticks.
<roh>
rjeffries: yes.. thats why i think doing a hundred and using picknplace makes sense. manual labour is expensive (atleast here)
<rjeffries>
wpwrak I'll be damned. re LEDtoy project. Too damn cool.
<wpwrak>
stefan_schmidt: the fw should be upwards-compatible anyway (for now)
<rjeffries>
roh the only way doing Femtoduino by hand makes sense (I think) is for a hobbyist who has more time than money
<wpwrak>
roh: (expensive labour) try to get some 1 EUR jobbers ? :)
<roh>
wpwrak: they cost money, not bring something.
<roh>
wpwrak: people who can do higher-level work like smt soldering have a real job.
<wpwrak>
roh: what is it for the employer - EUR 2/hour ?
<kristianpaul>
(ledtoy) cool :-)
<roh>
they'll cost you loads of money for broken stuff. besides that you only get them for stuff not done my regular workers.. (e.g. tasks which have no economic backing like cleaning parks et)
<wpwrak>
rjeffries, kristianpaul: glad you like it :) still needs some engineering, though. e.g., firmware/content updates are currently via an RS-232 dongle. and the case it some fragile DIY contraption with a lot of glue and wire. (needless to say, changing the battery is a pain)
<roh>
wpwrak: ive talked with farmers who dont use 1E jobbers but are back to eastern european helpers for the crop harvesting season. why? less broken crop. its difficult to stab  asparagus properly
<wpwrak>
roh: well, (illegal ?) immigrants from impoverished countries may also be a good choice. whatever works ;-)
<kristianpaul>
wpwrak: i do like the concept
<roh>
in the end. either pay workers properly (which they can live from) or pay twice ,) thats whats to learn there. low-wages jobs dont save any money. they lead to bad quality and more cost in total
<roh>
wpwrak: not illegal. remember.. the eu goes from the mediterain to russia now. they are all legal
<rjeffries>
wpwrak you are now famous on GooglePlus G+ I warned them that you do not use G+
<wpwrak>
rjeffries: hmm ? what made me famous ?
<[g2]>
would add wpwrak to my circle
<wpwrak>
what the world really needs is a good anti-social networking site ;-)
<rjeffries>
[g2] I am trying to figure out how to get the URL to those two posts I made about LED Toy and the guy who invented it
<roh>
wpwrak: already got it
<rjeffries>
wpwrak you and wolfsraul and rejon could all talk to each other. BUG smile
<roh>
wpwrak: the amount the 'social' shit spamms one its already antisocial. the whole posse
<rjeffries>
s/BUG/BIG/
<wpwrak>
the "bug smile" would be a lot scarier ;-)
<stefan_schmidt>
wpwrak: (anti-social networking) I thought IRC is exactly that
<rjeffries>
I am not an evangalist for social networking. I can report that i find a lot of smart creative sane people who I otherwise would never meet.
<rjeffries>
irc was the fisrt social network. get over it. ;)
<wpwrak>
rjeffries: perhaps you are too young to remember BITNET ? ;-))
<wpwrak>
those were the days. back then, a good high-speed link between universities was 9600 bps. the poorer ones, like oldenburg in germany, only had 2400 bps.
<rjeffries>
actually I was not. I went to university at one of the first 4 Arpanet nodes. those were eciting times.
<wpwrak>
"relay chat" was by sending messages between IBM mainframes (running VM/CMS), or non-IBM systems with some compatible stack for the IBM proprietary protocol. i think that one was even before SNA.
<wpwrak>
roh: (oled) only lives for ~2.5 years. pity.
<rjeffries>
A guy who wporked for me installed Unix on a  PDP that we converted from DEC RSTS os. The tape came directly from UC Berkely
<rjeffries>
wpwrak is OLED really so short lived in terms of durability"
<wpwrak>
rjeffries: says typically 15 khours on time, min. 20 khours storage lifetime
<wpwrak>
of course, this would explain why the industry is so interested in oled. much like why they love lithium batteries. built-in obsolescence.
<roh>
lithium batteries?
<roh>
wpwrak: do you seriously think lead acid or ni-cd/ni-mn is more useful=
<[g2]>
wpwrak, LiPO have the highest energy density
<[g2]>
by LiPOFe are safer
<[g2]>
and nearly the same energy density from my understanding
<roh>
also less easy to get in sane volume.
<roh>
lifepo4 is a bit bigger than li-po.
<wpwrak>
roh: nimh doesn't seem all that bad
<roh>
more volume. about the same as lead-acid
<roh>
wpwrak: its ok for short term bursts. but has a miserable lifetime
<wpwrak>
yup. energy density is limited in the alternatives
<roh>
i would use li-fe-po4 everyehere possible. or lead-acid (sealed) for where li-based stuff is too expensive or weight doesnt matter
<roh>
ni-* is dead to me.
<rjeffries>
my interest for a project I can not talk about is battery with very long life at very low drain. think a year or more
<roh>
rjeffries: li based one-time batteries.
<roh>
already on the market. easy to get
<wpwrak>
[g2]: seems that you missed the discussion of the wpan fw a bit ago. currently, you can use IEEE 802.15.4 without cdma and without acks. atben has reasonably fast turnaround time but atusb is slow (due to the protocol spoken between host and atusb being slowed down by how uhci is implemented)
<wpwrak>
roh: CR2032 !!!! ;-)
<roh>
intended for usecases like fire alarms or remote controls where you only need a very low amount of energy over a looong time and loose more by self-discharge than useage with regular batteries
<roh>
wpwrak: nope. those are much to low energy for drive a smoke alarm
<wpwrak>
roh: make it a silent alarm then ;-)
<wpwrak>
[g2]: but i have an improved protocol/firmware/driver for atusb in the works that should improve the turn-around time. that will also be an opportunity to switch on the chip's cdma and auto-ack features. with these, proper TCP-over-dirtpan should be possible. (right now, the lack of CDMA makes connections with more than very little traffic stall)
<[g2]>
wpwrak, thx... Sorry I haven't been following the logs as I should
<roh>
wpwrak: we have enough alarm cases that we use regular alkaline 9V blocks now
<roh>
works for ~2 years
<wpwrak>
as long as you remember to replace it in time ...
<roh>
it signals when empty enough
<wpwrak>
ah, nice
<roh>
they even mandate smoke alarms now.. not bad considered there are many torched buildings lately
<wpwrak>
pyromaniacs on the loose ?
<wpwrak>
or just the neighbourhood getting rougher ?
<roh>
i think criminals wanting to rent the flats to somebody else for more money than.
<roh>
just.. proove it. the roughness of the market when it comes to renting is evil.
<wpwrak>
ah yes, the dark side of good tenant protection
<roh>
thats why havint smoke alarms and good locks are basic survival
<wpwrak>
nice environment. i guess it must be almost as bad in the slums ;-)
<roh>
no. the market just collapsed. so these already criminals (well.. they build stuff..) got worse in their desperation
<roh>
can get worse, but then there is no reason to torch anymore.
<roh>
so is business working on speculation. fishy, criminal, bad for society. banks and housing are simply no business.
<roh>
bbl
<rjeffries>
I got a nice as in "low" quote to assemble my small qty of femtoduinos a.k.a. "walking stick human saftey system: or WSHSS lol
<rjeffries>
also known as a dead simple LED controller that is small and very portable and very low cost
<rjeffries>
My walking stick doesn't need Linux. Yet.
<roh>
rjeffries: what does it need a cpu for?
<rjeffries>
roh it doesn't NEED a cpu inherently. But that makes it easy to do some cool effects.
<rjeffries>
roh will I am not telling the truth. I hope to add a couple of sensors so it counts steps, yada yada.
<roh>
i see
<rjeffries>
maybe it will shock me if I do not walk briskly. I'll have to see.
<rjeffries>
have you played with EL wiring for glow-y effects?
<wpwrak>
something to add to my CV. X years of experience doing this, Y years doing that, yadda yadda, N people praise me on G+ ;-)
<roh>
wpwrak: hrhrhr
<roh>
wpwrak: dont worry.. we can sit that one out.
<wpwrak>
rjeffries: (walking stick) add some wireless receiver and sell the corresponding transmitter as a cheap car add-on. that way, your walking stick can flash when one of these silent e-cars sneaks up on you. phase 2: lobby to make this a mandatory safety features in all cars whose noise level is below a ferrari breaking the sound barrier ;-)
<wpwrak>
rjeffries: well, phase 1.5. put the product on the market and invest in mass advertizing. then, when one of your walking-stick customers gets hit by an e-car, join a case with an amicus brief stating that the car driver did not take all reasonable precautions to avoid such accidents. that will let your customers sue for an even more insane amount. that precedent will greatly smoothen the lobbying process.
<wpwrak>
(they did more or less that with finger protection for saws. someone invented and patented such a protection system, then managed to make it mandatory. voila, instant monopoly !)
<rjeffries>
wpwrak you should be a defence attorney
<rjeffries>
wpwrak i have to find a cool way to leverage 802.15.4 ob the walking stick
<rjeffries>
maybe it knows when i leave, alerts my wife and dogs and any criminal who have a Ben
<rjeffries>
then as I walk back near the front gate, it gives another alert
<rjeffries>
or given the 10 meter range of your modules I put a system on my minature horse. and place a few other 802.15.4 stations at various locations in or era his pasture an dbarn
<rjeffries>
then have a reak time more or less HORSE GPS
<wpwrak>
roh: indeed, ACME :) but i don't seen uSD->VGA. i still win ;-)
<rjeffries>
roh that 4dsystems GPS module is clever
<roh>
wpwrak: hrr
<wpwrak>
rjeffries: there may actually be a market for a system that warns an intruder of the approaching tenant, with enough time to make a discreet, non-confrontational departure
<rjeffries>
au 29 seems not very expenive
<rjeffries>
wpwrak indeed especially if a mistress or lover is involved. yes, that could be a money maker for sure
<rjeffries>
au 29 in refernce to 4dsystem GPS microsd module
<rjeffries>
if it is real
<wpwrak>
rjeffries: (tenant annunciator) should actually be easy to implement in multi-apartment buildings: use an RFID card for front door access and sends a message via some internal network to the terminal(s) in the respective apartment.
<wpwrak>
rjeffries: you need RFID (and not just a swipe card) in case the person in question finds the door open and enters without a swipe.
<rjeffries>
wpwrak it is clear you will soon be a VERY rich man, on the order of Bill Gates, or at a minimum Steve Jobs. certainly on par with wolfspraul. ;)
<Ayla>
wolfspraul is rich?
<wpwrak>
rjeffries: hmm, if wolfgang keeps buying fake component in shenzen, we may indeed find ourselves on par soon ;-)
