[08:25] <jcoxon> good work m1x10
[08:25] <jcoxon> they are good modules
[08:25] <m1x10> yes they seem to
[08:25] <robint91> which modules
[08:26] <m1x10> robint91: http://www.seeedstudio.com/depot/gps-bee-50-channel-ublox-5-p-560.html
[08:26] <robint91> ah
[08:28] <m1x10> robint91: in yesterday's schematic you wired the breakout with the i2c. right?
[08:28] <robint91> yes
[08:29] <m1x10> do u know the wifly library?
[08:30] <robint91> I know what a wifly is
[08:31] <m1x10> yes
[08:31] <robint91> but the library
[08:31] <robint91> not
[08:31] <m1x10> the wifly also does need sometimes that converter breakout
[08:31] <m1x10> so the library makes added to the main wifly lib
[08:31] <m1x10> a spi2uart lib
[08:32] <m1x10> but they dont have an i2c2uart lib :(
[08:33] <robint91> someone on #sparkfun has tested it with i2c
[08:34] <m1x10> check your mail, ive sent you the wifly lib
[08:37] <robint91> m1x10 I don't know the exact I2C commands work in arduino
[08:37] <robint91> but in spiUart.cpp
[08:38] <robint91> the function on line 126 and on line 139 needs to be changed
[08:38] <m1x10> why?
[08:38] <robint91> the select and transfer and deselect are the spi commands
[08:38] <robint91> you need to change that into i2c commands
[08:39] <m1x10> see, there's no actual support for the i2c
[08:40] <robint91> http://www.arduino.cc/playground/Learning/I2C
[08:41] <m1x10> I have used i2c with the pressure sensor
[08:41] <m1x10> I can just use it in the same manner to read the rx/tx of the gps?
[08:42] <robint91> yes I think so
[08:42] <m1x10> -think so-

[10:06] <m1x10> sure*
[11:15] <m1x10> hmm

[20:46] <m1x10> what do u mean dub?
[20:47] <Lunar_Lander> I watched a video about a teenager who got a shock from the overhead line when he climbed on a rail car
[20:47] <fsphil> get greek actors to do the voices

[20:49] <m1x10> e yes
[20:49] <Lunar_Lander> actually
[20:49] <Lunar_Lander> in the Spanish version of T2, he says "Sayonara"
[20:49] <m1x10> and thats not the only bad

[21:19] <Lunar_Lander> do you need it for a small payload?
[21:19] <jcoxon> yes
[21:19] <Lunar_Lander> yeah
[21:19] <Lunar_Lander> I don't know a source either
[21:19] <Lunar_Lander> it is like the hardest job to find PS boxes
[21:19] <Upu> 1/ Can make 'em 2/ I'll speak to wife she gets vaccines in them
[21:20] <jcoxon> Upu, i've done my days of making them
[21:20] <jcoxon> :-)
[21:20] <Upu> I quite enjoy it was modifying mine this afternoon
[21:21] <Upu> no camera payload I guess ?
[21:21] <jcoxon> nah
[21:21] <jcoxon> i haven't launched a camera in a long time...
[21:21] <jcoxon> i might try my hospital path lab
[21:21] <jcoxon> they should have loads
[21:21] <Upu> have you tested your heater yet ?
[21:22] <jcoxon> my crystal heater - yes

[21:23] <Upu> did it stop the frequency drift though ?
[21:23] <jcoxon> it reduced it
[21:23] <Upu> so worth doing then
[21:24] <jcoxon> and i reckon with even better insulation it would stop it
[21:24] <jcoxon> depends on your flight really
[21:24] <jcoxon> on a normal flight its not that important

[22:47] <Randomskk> and shat brix, there are little bacteria swimming around
[22:47] <Randomskk> it's great

[22:50] <Lunar_Lander> I mean the laser device
[22:50] <SpeedEvil> it's a drop of water, and a laser
[22:50] <Lunar_Lander> yea
[22:50] <SpeedEvil> $3ish from dealextreme.com
[22:51] <SpeedEvil> I got a green 50mW module for $20 IIRC
[22:51] <SpeedEvil> works well
[22:51] <Lunar_Lander> does any laser do?
[22:51] <fsphil> Randomskk, so that works? I never got around to trying it
[22:51] <Randomskk> fsphil: yea! I was really surprised
[22:51] <fsphil> fantastic
[22:51] <Randomskk> but literally I just took my laser in my hand, a drop of water suspended on the first piece of plastic I found (a pen) and shone it through
[22:51] <Randomskk> instantly on the wall an awesome display
[22:52] Action: fsphil gets a pen ... :)
[22:52] <Randomskk> really awesome though. it's fascinating. wonder where my camera is
[22:53] <Randomskk> wonder what else to try it on, too
[22:53] <SpeedEvil> I think you must be seeing a reflection, in order to get a focussed image
[22:54] <Randomskk> want a photo?
[22:54] <fsphil> hmm.. I can't form a drop
[22:54] <Randomskk> I don't know a huge amount about optics or microscopes
[22:54] <Randomskk> fsphil: what I did was
[22:54] <SpeedEvil> something with tails that swim, diluted?
[22:54] <Randomskk> SpeedEvil: assuming you're thinking what I'm thinking
[22:54] <Randomskk> I want to find something else first
[22:54] <Randomskk> fsphil: take a pen with a clicky back
[22:54] <Randomskk> then use the top of the pen and just dip it in some water
[22:54] <fsphil> ooh yes
[22:54] <Lunar_Lander> anyone got an idea why this works?
[22:54] <fsphil> or a straw
[22:55] <SpeedEvil> Waters refractive index is not high enough to form a focal plane inside the drop
[22:55] <Randomskk> fsphil: that'd work
[22:55] <Randomskk> SpeedEvil: could it reflect off the edge of the drop?
[22:55] <SpeedEvil> So I'd guess what you are seeing is a reflected image off the drop side
[22:55] <SpeedEvil> yes
[22:55] <Randomskk> SpeedEvil: the website there says he's seeing paramecia, which are apparently 50 to 350µm
[22:55] <Randomskk> readily available things with tails that swim are approx 3 to 5µm wide and 45µm long
[22:56] <Randomskk> so possibly too small
[22:56] <Randomskk> admittedly I don't know what geometric property is going to be controlling the scale
[22:56] <Randomskk> possibly a larger or smaller drop would have a significant effect
[22:56] <fsphil> holy crap it works!
[22:56] <Randomskk> :D
[22:56] <Randomskk> how cool is that
[22:56] <fsphil> not much swimming about
[22:57] <fsphil> but definitely a few things
[22:57] <Randomskk> I had things moving in what would appear to be non-uniform-flow directions but I can't be sure
[22:57] <fsphil> I wonder if it's bright enough to video it
[22:57] <Randomskk> probably. turn the room lights off
[22:57] <fsphil> I've got a lot of long strand things
[22:57] <Randomskk> wish I had a video cam
[22:57] <fsphil> they don't move
[22:57] <Randomskk> hmmm, my sister's dslr does video
