01:27 <rjeffries> I've done a couple of orders to Seed Studio recently, small stuff such as sensors, and then yesterday a few cheap solar panels

01:29 <rjeffries> Seed has an impressive system where they automatically send reports on your order status via email. cool beans. I also ordered a Bus Pirate

01:31 <wpwrak> haven't e-mail updates on order status pretty much been standard for the last 10-20 years ? :)

04:26 <rjeffries> wpwrak maybe so, but Seed updates you through the process at each stage. In any case, they are easy to do business with IMO.

04:28 <wpwrak> that's all that counts :)

11:04 <whitequark> can anyone suggest a good scope for $2000 USD?

11:13 Ayla joined #qi-hardware

11:25 <whitequark> preferably from somewhere like China to avoid the customs as much as it possible

11:27 rzk joined #qi-hardware

11:28 <blogic> whitequark: channels, bandwidth, samples ...

11:28 <blogic> ?

11:31 kuribas joined #qi-hardware

11:39 wej joined #qi-hardware

11:39 jivs joined #qi-hardware

11:53 <whitequark> blogic: 2 channels, definitely need 48MHz digital, best if could handle 133MHz of PCI-E

11:54 <whitequark> so I guess that'd be somewhere near 300MHz

11:54 <blogic> and you want to get it as cheap as possible ?

11:54 <blogic> or as good as possible with max 2k ?

11:54 <whitequark> well, a friend of mine has $2k from the company to buy a new scope

11:54 <blogic> i have gotten good results with rigol units

11:54 <blogic> they are semi pro i guess

11:55 <blogic> not like a hameg or textronik

11:55 <blogic> but they work

11:55 <blogic> and are payable

11:55 <whitequark> well, I know about 1102e, but it's only 200m

11:55 <whitequark> *100m

11:55 <blogic> there is a 200mhz version

11:55 <whitequark> hm

11:55 <blogic> i used the 50mhz version with the 100mhz hack

11:55 <blogic> they work

11:55 <blogic> but dont expect it to be like a hameg

11:55 <whitequark> yeah, I know about the hack

11:55 <whitequark> I'll get one 1152 next month

11:57 <blogic> a bit off topic

11:57 <blogic> the other amazing tool that i started using recently is this

11:57 <blogic> http://www.saleae.com/logic/

11:57 <blogic> best 150$ i spent in several years

11:58 <blogic> bit annoyed as the 16 channel version came out just after i ordered the 8 channel version

11:58 <whitequark> +1

11:58 <blogic> still its a great tool and safed me several hours twice already

11:58 <blogic> ok ;)

11:58 <whitequark> I like that a lot too. Also, native linux support

11:58 <blogic> yep

11:58 wolfspraul joined #qi-hardware

11:58 <whitequark> don't need a logic analyzer now, but when will, I'll definitely go for saleae

11:59 <blogic> hehe

11:59 <blogic> it helped me debug spi flash drivers for openwrt

11:59 <whitequark> http://www.rigolna.com/products/digital-oscilloscopes/ds1000ca/ds1302ca/

11:59 <whitequark> ^ this one seems reasonably good

12:00 <whitequark> and there are $500 more to spend, e.g. for delivery and bribing of customs

12:00 <blogic> interseting

12:00 <blogic> which country doe it get posted to ?

12:00 <blogic> i mean where are you based

12:00 <whitequark> russia

12:01 <whitequark> and, yes, it sucks.

12:01 <blogic> ah cool

12:01 <blogic> what does ?

12:01 <whitequark> anything, but the postal service especially does

12:01 wejp joined #qi-hardware

12:01 <blogic> i just wondered about the "bribing" bit ;)

12:01 <blogic> ah ok ;)

12:01 <whitequark> yeah

12:01 <whitequark> I was dead serious

12:01 <blogic> i know

12:06 <wolfspraul> blogic: you contacted me I think?

12:06 <wolfspraul> here I am, happy, so... what can I do for you? :-)

12:07 <blogic> hrr hrr

12:07 <blogic> the best part is the happy bit

12:08 <blogic> i will switch to /pm if you dont mind to not flood the channel with of topic foo

12:52 <wpwrak> whitequark: do you care about memory depth ?

12:52 wejp joined #qi-hardware

12:52 <wpwrak> whitequark: the rigol CA series are fast but have only quite limited storage

12:53 <wpwrak> i.e., 5 kSa per channel: http://www.tequipment.net/RigolDS1302CA.html

12:54 <wpwrak> the B series is similar: up to 200 MHz and 4 analog channels, but only 8 kSa: http://www.tequipment.net/RigolDS1204B.html

12:56 <wpwrak> the D, E, C, and CD series all have deep memory. 500 kSa/channel.

12:57 <wpwrak> the D and E are successors of C and CD, with a higher sample rate. C and CD sample only at 200-400 MSa/s (2/1 channel), while D/E do 500M/1G

12:59 <wpwrak> C and E have two analog channels. CD and D have an additional 16 channel logic analyzer. it's not the greatest in the world, but it has its uses.

13:17 <blogic> xiangfu: ping

13:17 <blogic> the wpan.mk i gave you has a bug in it

13:17 <xiangfu> blogic, pong

13:18 <blogic> i willupdate it today

13:18 <blogic> jivs found a bug

13:18 <xiangfu> oh.

13:18 <blogic> 16:39 < blogic> the CONFIG_IEEE802154_DRIVER=y vs CONFIG_IEEE802154_DRIVERS=y looks like the candidate for the borkage

13:18 <blogic> (missing S ... DRIVER vs DRIVERS)

13:19 <blogic> might want to fix it in your repo. i am not sure where jivs pulled his tree from but assume it was qi tree

13:21 <blogic> xiangfu: the 2nd question is your 3.0 patches in patchwork.openwrt.org

13:21 <blogic> lars_: are you doing those patches ?

13:22 Artyom joined #qi-hardware

13:23 <xiangfu> blogic, those two patches is out date. I think I should send the new patches.

13:23 <blogic> ok

13:23 <Artyom> Hi Kristianpaul

13:24 <blogic> i will drop them from patchwork in that case if that is ok with you

13:25 <xiangfu> blogic, yes. sure.

15:21 <jivs> Hi blogic

15:22 <jivs> Have you had time to try for the missing modules

15:23 <blogic> not yet

15:23 <blogic> i am hunting a gcc bug

15:23 <jivs> ok

15:24 <jivs> i think you mentioned we can try to manullay insmod the missing modules.

15:24 <jivs> If you guide me I will try that..

15:25 <blogic> ok

15:25 <blogic> insmod /lib/modules/2.6.XY/*.ko

15:25 <blogic> call that like 5 times

15:25 <blogic> you will see errors

15:25 <blogic> but eventually all modules will be included

15:25 <blogic> its a crude and brutal way of doing it

15:25 <blogic> :D

15:25 <blogic> but it will work

15:26 <jivs> that on the toolchain? or ben

15:26 <blogic> ben

15:27 <jivs> okay, but mine is 3.0.0 , i think that normal isn;t it as i have new kernel..

15:27 <blogic> yes

15:27 <blogic> insmod /lib/modules/3.0.0/*.ko

15:28 <jivs> insmod: can't insert '/lib/modules/3.0.0/af_802154.ko': File exists

15:28 <jivs> giving the same error each time... tried 5-6 times

15:30 <jivs> i think it accepted the spi_atben.ko one,

15:31 mstevens joined #qi-hardware

15:31 <blogic> so they are all there now

15:31 <blogic> lsmod please and pastebin the result

15:32 xiangfu joined #qi-hardware

15:32 <jivs> ok

15:33 <jivs> lsmod :- http://pastebin.com/z6h85XWC

15:33 <blogic> spi_atben is missing

15:34 <blogic> do a insmod on that file and see if you get an error

15:34 <blogic> (potentially call "dmesg" to see it)

15:35 <jivs> ok

15:36 <jivs> [ 290.240000] spi_atben spi_atben: Setting up ATBEN SPI

15:36 <jivs> [ 290.250000] spi spi32766.0: ATBEN ready for mischief (IRQ 164)

15:37 <jivs> spi_atben now appears on lsmod

15:38 <blogic> cool

15:39 <blogic> in theory a ifconfig -a should now show you some results

15:39 <blogic> this is how far i got with my setup last week :D

15:39 <blogic> did not get any further

15:41 <jivs> yes, hardwpan0 is there

15:42 <blogic> hmmm

15:42 <blogic> not sure then

15:43 <jivs> what interface did u got?

15:44 <blogic> i used a atusb dongle

15:44 <blogic> and i cant recall what it was called

15:45 <jivs> okay

15:47 <jivs> not sure but it needs to create some kind of tunnel as well..

15:48 <jivs> anyway, it a step forward, i will play with this and report here if any progress...

15:48 <jivs> thanks blogic

16:36 fossrox joined #qi-hardware

16:37 <jivs> blogic, I am comparing this new ben with another ben which has werner's hacked kernel and dirtpan installed

16:37 <jivs> i am wondering if we will still need those IZ commands from zigbee to get dirtpan working..

16:38 <jivs> when i do iz assoc on the new ben, it says address registered.

16:38 <jivs> but the dirtpan command fails with error can't bind 802154 device...

16:55 <blogic> no idea

16:55 <blogic> you are now further in your venture than i am

16:55 <blogic> :D

16:55 <blogic> however i just fixed my gcc bug :D

16:55 <jivs> ok cool

16:57 <jivs> i will continue trying it, lets see how far i can go :-)

22:40 <wpwrak> kyak: btw, an idea for qi-bot: it could look for s/pattern/text/ and do the editing for us :)

22:40 <DocScrutinizer> gleitzeit, ST-E hatte heute keine zeit fuer ein empfangscommitee

22:41 <DocScrutinizer> 1 day in debit already, on my worktime account

22:42 <wpwrak> funny :)

23:37 <PiLeS> OK I have a thought for you; should keep you awake all night :D

23:37 <PiLeS> Why does the xburst toolchain has to be bigger than the Ben's NAND?

23:38 <PiLeS> Now you try to sleep :P
