<n3glv_McWifi>

nice
<buZz>
how much watt motor do you have?
<buZz>
and how many volts batteries?
datagutt has quit [Ping timeout: 245 seconds]
<n3glv_McWifi>
the controller I have now is 35A @ 24v
<n3glv_McWifi>
I have two battery options, 40ah @ 24v and 30Ah, both are LiFeP04
<buZz>
but how much watt is the motor?
<n3glv_McWifi>
so there are some '1000w' controllers on ebay
AdvancedNewbie has quit [Remote host closed the connection]
<buZz>
thats ~40A
<n3glv_McWifi>
it can handle the 35A no problem, the first one lasted 6,000mi
<buZz>
1000W
<n3glv_McWifi>
yeah the one I may get is rated at 700
<buZz>
a bit more
<buZz>
42A
<buZz>
700W?
<buZz>
but
<n3glv_McWifi>
35A is 800something
<buZz>
how much watt is your motor
<n3glv_McWifi>
that is only on hills
<buZz>
35*24=840
<n3glv_McWifi>
I draw 9.5-10A on the flat, no wind etc
<n3glv_McWifi>
and my BMS is good for 60A peak
<n3glv_McWifi>
20 continuous

I just emailed the president of the company that made the bike
<buZz>
i have about 100 recycled li-ion cells
<n3glv_McWifi>
asking for a price quote
<n3glv_McWifi>
want to sell some 18650 cells?
<buZz>
no :)
<buZz>
and have been playing with the idea of grabbing a 250W hub motor (max allowed in .nl) and building my own motor controller
<n3glv_McWifi>
I'm planning on buying up some new-old-stock HP packs
<buZz>
and just stuffing the frame of a bike with 18650 :P
<n3glv_McWifi>
do you know you can use a car alternator as a motor?
<buZz>
hmm, probably
<buZz>
but
<buZz>
windscreen wiper is a lot better at it :P
NamanG has joined #cubieboard
<n3glv_McWifi>
meh, depends
<buZz>
and old laptop packs are a GOOD source for good 18650 , ppl throw them out when they stop working 'beyond 5 minutes' BUT that just means -one- of the cells is bad, not all
<n3glv_McWifi>
I know guys runnin a power wheels race car (go-cart) with two 130amp alternators, they get around TEN horsepower!
<n3glv_McWifi>
I'm thinking of building a 'delta trike' with an alternator motor
<buZz>
well here its only legal to add electric motors on bicycle as 'help'
<buZz>
if you make it go by itself on motor, you need to have it checked etc
<buZz>
fucking bureaucrazy
<n3glv_McWifi>
yeah, you must have cadence sensor etc
<n3glv_McWifi>
no twist-and-go mode
<n3glv_McWifi>
my bike is all TAG
<n3glv_McWifi>
;-)
<buZz>
uhuh
<buZz>
TAG?
<buZz>
ah
<n3glv_McWifi>
pedal sensor not even hooked up
* n3glv_McWifi
evil grin
<buZz>
in which country do you stalk pedestrians?
<n3glv_McWifi>
usa

<NamanG>
trying to use serial console. on doing picocom -b 115200 /dev/ttyUSB0 i get "FATAL: cannot open /dev/ttyUSB0: Device or resource busy". but on doing fuser /dev/ttyUSB0 i see no processes using ttyUSB0. how do i rectify this?
<n3glv_McWifi>
NamanG: try sudo
<buZz>
indeed
<n3glv_McWifi>
or add your user to modemusers (or whatever group needs to use com)
Deskwizard has joined #cubieboard
<buZz>
dialout usually
<buZz>
or uucp
<n3glv_McWifi>
ah, that's it yeah
<n3glv_McWifi>
dialout
<n3glv_McWifi>
I'm all xubuntu or debian
<n3glv_McWifi>
I use it to controll my ham radio system
<n3glv_McWifi>
via vnc
<buZz>
same
<buZz>
no hams though
<buZz>
i am a 100% salami guy
<n3glv_McWifi>
flrig runs the kenwood radio and fldigi is the soundcard modem stuff
<n3glv_McWifi>
so I can run digital modes on shortwave from here at mcdonalds
<NamanG>
sudo worked. picocom working. though now i dont see anything on it while booting (the android from nand)
<buZz>
NamanG: maybe rx and tx are swapped?
<buZz>
also DONT connect power!!! ONLY GROUND
<n3glv_McWifi>
NamanG: it's ownerships/groups permissions issue on the usb port / device
<NamanG>
buZz: yes took care of that
<NamanG>
what do you mean by permission issues? how do i sort it?
<n3glv_McWifi>
lol, poor guy in front of me has rebooted his M$ laptop at least 20 times in last 30min trying to get online
<n3glv_McWifi>
NamanG: add your user to dialout (or as buZz said, uucp) group
<n3glv_McWifi>
should fix it
<NamanG>
added to dialout as well as uucp. nothing changed :|
<n3glv_McWifi>
need to logout then back in
<NamanG>
did that
<n3glv_McWifi>
(not restart, just log out)
<NamanG>
yes did that. didnt work! i dont understand what could be going wrong?
<NamanG>
tried swapping Rx Tx too. nothing
<NamanG>
n3glv_McWifi: this is what i see on lsusb: http://sprunge.us/NIJH is it possible that i am using a wrong serial port?
<n3glv_McWifi>
dunno, I don't have a cubie yet
<n3glv_McWifi>
just going from generic linux info
<NamanG>
oh i see. any other tips on where i could look into?
<buZz>
NamanG: are you on the right baudrate? 115200?
<n3glv_McWifi>
is it udev buZz?
<buZz>
no, if you can open the device (maybe as root) udev cant stop you from reading it
<Deskwizard>
maybe, never looked into it, probably, but why bother... (wow i cant believe I said that :P) lol
<n3glv>
it's possible to stack these modems for more radios/ports
<Deskwizard>
yeah ive notice, well designed
<n3glv>
talked to the guy on and off for hours @ orlando hamcation
<n3glv>
I traded a full sized controller with hardware state machine for the pi thing
<Deskwizard>
with the proper hardware, I'm guessing you could HAM to home from mobile and dial over landline?
<Deskwizard>
...nevermind... cellphones ... lol
<n3glv>
there are people who use aprs to control things
<n3glv>
it can in theory do a shell session
<n3glv>
but, can't be encrypted or do business over it

obviously, I've lost my antenna... lol
<joph>
has anyone here a navspark?
<Deskwizard>
uhm, strange little thing
<joph>
i connected to mine (gps+glonass) an external active gps antenna via an sma pigtail, I'm unable to receive any signal with this antenna, with the included antenna i receive a lot of satellites
<joph>
now i'm not sure if it's probably necessary to adjust the settings or probably my sma gps antenna is damaged
<Deskwizard>
at least you have an antenna, I just plugged in ym gps module and cant find my antenna lol :P
<Deskwizard>
I wouldnt know about the settings, hard to tell if its the antenna without a second one to test with ... :S
tydaikho1 has quit [Remote host closed the connection]
red723 has joined #cubieboard
<buZz>
he does have a second antenna ;)
<buZz>
pigtail antennas rarely work well for GPS
<buZz>
its probably ment for 2.4ghz
<Deskwizard>
well mine is definetly a goner... I can picture in my mind how i packaged it, all nice and all... but I cant find the fucking thing....
<Deskwizard>
very valid point about the pigtail, didnt think about that one
<Deskwizard>
I need better storage ... lol
<buZz>
:)
<buZz>
i dont know where my gps antenna is either ..
<Deskwizard>
i was wondering about that though since GPS is also 2.4ghz iirc
<buZz>
probably in my attic
<buZz>
no! its not
<buZz>
its very low freq
<Deskwizard>
I see, i must have crossed the wires between gps and bluetooth
<buZz>
oh not -so- low
<buZz>
1.2ghz and 1.5ghz
<Deskwizard>
Oh wait ! there it is !
<buZz>
my gps module has a bt radio ;)
<buZz>
but i have 'some' tomtom external gps modules ..
<Deskwizard>
1575.42 mhz
<buZz>
they should be TTL level, not sure
<Deskwizard>
god damn it, the adapter isnt with it
<Deskwizard>
*fawk*
<buZz>
Each GPS satellite transmits signals on two frequencies: L1 (1575.42 MHz) and L2 (1227.60 MHz).
<buZz>
The L1 frequency contains the civilian Coarse Acquisition (C/A) Code as well as the military Precise (P) Code. The L2 frequency contains only the P code. The P code is encrypted by the military—using a technique known as anti-spoofing—and is only available to authorized personnel.
<buZz>
:D
<buZz>
it depends
<buZz>
sometimes they put the P code into CA
<Deskwizard>
hence the L1 frequency on my antenna
<buZz>
often, but
<buZz>
when they (USA) invades your country
<buZz>
they turn off CA
<buZz>
;)
<Deskwizard>
why doesnt that surprise me the slightest... hehe
<buZz>
i am quite happy with my results of yesterday
<buZz>
needs some work still, but getting really really close to how i want it :)
<Deskwizard>
nice
<Deskwizard>
oh cool i found the adapter!
<buZz>
\o/
<Deskwizard>
on a side note, electronic store has some old 3½ floppy drive drawers for sale on the cheap, that could be nice to put all the little modules and random boards I have
<Deskwizard>
drive = disk*
<buZz>
perhaps :) i like those cabinets with 9834753847 drawers for that
<Deskwizard>
yeah I have some but the drawers are too small
<Deskwizard>
uhm, i think there might be something wrong with that antenna ... *sigh*

hi all!
<snors>
I know this is not a helpdesk or something but…. received my Cubietruck a couple of days ago I’m trying to play h264 HTML5 vids through a browser. Android seems to be playing the videos fine but if I try Lubuntu, Fedora, Cubian, Cubieez or any other Cubieboard compatible distro I can’t get the video playing smooth through a browser(tried Chromium, Iceweasel, Midori. This could have something to do with the CedarX not working in
<snors>
browsers but can someone please confirm?

playing around with the device for hours, lots of fun but just don’t want to spend another month while someone here can directly tell me it isn’t going to work anyway
<rooted-arm>
did you try gnash web browsers plugin ?
<snors>
no I did not on what browser should I try this?
<rooted-arm>
all browsers ?

I see yes, looking on their website let me give it a try thank you!
<rooted-arm>
anytime.
<snors>
really impressed by the performance of the board tho
<Deskwizard>
snors: yeah me too! didnt expect that much ! :)
<snors>
just hoping that I’ll get h264 vids playing smooth in a browser
<Deskwizard>
Hope you get it too! thanks for the comment on them working in android, thats good news for me ! :)
<Deskwizard>
brb booting in linux
<snors>
ye also CSS3 animations
<snors>
just as smooth as on my 27” imac
<rooted-arm>
well , if you tried raspi , then beagle bone black , and read something about cubietech A20 , youll know its a kick-ass , and when you read about A80.... then x-gene
<snors>
I’ve a raspi here ye
<snors>
what browser do you guys advice in combination with gnash plugin ?
<snors>
chromium seems to be broken on debian

<rm>
it's only available for amd64 and i386 in debian
<snors>
so no way to get it installed on a cubieboard?
<rm>
you could try bulding from source, but chances are if Debian wasn't able to do this, then there are serious reasons preventing it from working on other architectures
<snors>
hm ok I see, so what would be your advice ? I’m trying to play html5 h264 video in a browser with the gnash plugin
<snors>
midori doesn’t support h264 so
<snors>
iceweasel / gnash would be something good to try ?
