[00:08] <robert1971> edmoore: The iQ should interface pretty much the same way as the iQ save 3.3v instead of 5.0v?
[00:09] <edmoore> not sure, but i would have thought so - they're basically all just gotcha-free serial comms
[00:10] <robert1971> Just reprogramming the nema output of the SKII only 2 sentances enabled by default
[00:10] <robert1971> Thats what I'm thinking too. I think that data cable around the wrong way did for it. 2nd attempt tomorrw

[00:29] <edmoore> nova9
[00:29] <Laurenceb_> features?
[00:30] <edmoore> balloon
[00:30] <Laurenceb_> lol
[00:30] <Laurenceb_> just cameras and such?
[00:31] <Laurenceb_> anything special?
[00:31] <edmoore> we'll see! depends on several things, that are unlikely to happen, happening
[00:31] <robert1971> :)
[00:32] <Laurenceb_> :D
[00:32] <Laurenceb_> a mini black hole from the LHC
[00:34] <Laurenceb_> edmoore: did you just stick your radiometrix module on a GPIO ?
[00:34] <edmoore> dac
[00:34] <Laurenceb_> ah
[00:34] <Laurenceb_> pulse shaping?
[00:35] <edmoore> nope, just voltage keying
[00:36] <robert1971> Quick question on power. Am i better going for 9vPP3 to power beacon or 4xAA. I need 5v and i'm converting it through a switching regulator. PP3 is lighter than 4AA hence my preference for PPC or am I missing a trick?
[00:36] <Laurenceb_> so how did you control it? from a task set to run at 50Hz?
[00:36] wickerwaka (n=akawaka@external.treyarch.com) left irc: Read error: 110 (Connection timed out)
[00:36] <edmoore> 4xAAA :)
[00:36] <Laurenceb_> robert: capacity
[00:36] <Laurenceb_> also be careful with smps
[00:36] <Laurenceb_> they can get too cold
[00:36] <robert1971> Thanks. SMPS?
[00:37] <edmoore> smps is pretty sound, I think - the ones I pointed out anyway
[00:37] <edmoore> smps = switched mode power supply
[00:37] <robert1971> Missed the obvious AAA :)
[00:37] <edmoore> so basically go for whichever gives you the watt-hours
[00:37] <robert1971> TI has a -40c min
[00:37] <edmoore> voltage x capacity
[00:37] <robert1971> Texas Inst.
[00:37] <Laurenceb_> yeah sounds ok
[00:38] <Laurenceb_> as long as you check everything works

[13:48] <ShellEvil> Non-cheap though.
[13:54] <edmoore> ShellEvil: where did you find a price for them?
[13:54] <ShellEvil> Oh - I mailed them.
[13:54] <ShellEvil> $250 per

[13:54] <edmoore> per axis
[13:54] <ShellEvil> yes

[13:55] <edmoore> still not cheap
[13:55] <ShellEvil> No.
[13:55] <ShellEvil> 5ug/sqrt(Hz) is nice though.
[13:55] <edmoore> yeah, spotted that
[13:55] <ShellEvil> prolly need ovened to slightly approach that, but still.

[15:34] <rharrison_quiet> Just sent you a copy of the response from dpie on the iQ data cable. They agree that the data cable is indeed around the wrong way for the conventional iQ connection.

[15:35] <edmoore> well good to know, thanks

[15:36] <rharrison_quiet> I thought of a couple of stonger obsenities for them :) But I thought it might be best to pass this wisdom on for the future iQ'ers out there
[15:37] <rharrison_quiet> The pin out info is on page 230
[15:37] <rharrison_quiet> Not the first page i turned too in my excitment to get things going...
[15:37] <edmoore> i would probably have not noticted that
[15:37] <edmoore> we just bypassed it by designing our own pcb for it to go on
[15:38] <edmoore> so when we wnt for a connector, that would have bitten us in the arse
[15:38] <rharrison_quiet> With your own header?
