[00:43] i wouldn't try it [00:43] not when you're going to put the whole thing through a temperature stress test, which will probably cause the batteries to lower in capacity [00:43] i was hoping someone wasn't going to say that :/ [00:44] why can't you get 3.3v? [00:44] solution is another battery = another balloon [00:44] its a pico flight, the 1000mah lipo is only giving me 2.95 on the gps [00:45] eek [00:45] yeah i wouldn't try that [00:45] Boost Converter? [00:45] hm possibly, hadnt thought of that [00:48] Sparkfun is a little distant for you, but we've used these with success: http://www.sparkfun.com/products/9216 [00:49] ah that's the 1, but thinking it through, the weight of a battery plus the converter .. itll be almost the same as an extra lipo [00:50] Darkside: there? [00:50] yep [00:50] pm? [00:50] yep [00:50] NigeyS: If you want me to weigh that converter real quick, I've got one around here somewhere. [00:51] I'm sure it weighs less than an extra lipo. [00:51] sure, if you dont mind, that would be great [00:51] anything under 4gms i can be ok with [00:53] That converter in particular weighs 1.1g [00:53] wow, alot lighter than i thought, thanks zuph ! [00:53] NigeyS: err - why are you only getting 2.95? You mean starting with a low battery voltage? [00:54] Li-po is quite flat at ~3V [00:54] well the lipo is shoving out bang on 3.7 but after hitting the vreg, and the diode, im getting 2.95 max out of the serial ttl [00:54] why diode? [00:54] james put it on .. so i dont blow things up i think [00:55] and i measured the diode drain, it was minimal, most of the loss is the vreg [00:55] Not in principle insane, but a polarised connector would sort that hastle. [00:55] The diode will be dropping at least 0.3V - even if shottky [00:55] shottky [00:55] well i got .27 max drain [00:55] Action: SpeedEvil can never remember how to spell that [00:56] hehe its late you can be forgiven [00:56] naah.

[12:53] ahh yes it looks like it [12:53] its been updated for california to .. [12:54] The shape of the NOTAM would be more or less consistent I think with them pointing the spot beam at one point on the earth, and meaconing from it. [12:54] i wonder how badly it will affect ground signals [12:55] interesting stuff [12:55] wonder if its anything to do with that new satellite they put up not so long ago aswell. [12:56] Darkside: It has a 250nm radius at 4000 feet - so I assume that's practically the radius on the ground [12:56] yeah [12:56] interesting [12:56] A fun fact is that the internet makes many of the 'conventional' ways of degrading GPS useless. [12:56] no mobile phone gps, people will be lost, taxi drivers will have to use a MAP and compass..lol [12:57] Or useless to a skilled opponent with a small differential GPS in the area, and internet connectivity to it [12:58] The conventional ways just introduce an error into the orbital position reports. But if you isupply your own orbital models, and models of how the clock is vaying at a given time, you can correct for simple orbit or clock wander approaches [12:58] Also - nonconventional. [12:58] Google, bing, et al now have ~1m imagery of many parts of the world. [12:59] This is quite good enough to accurately locate yourself, if you're a missile. [13:00] scary thought though [13:00] using google earth / maps to aim a missile :| [13:03] In late December, the agency’s Space Operations Mission Directorate requested the shuttle and International Space Station programs take the necessary steps to maintain the capability to fly Atlantis on the STS-135 mission. [13:03] yey! [13:04] Fuck [13:04] oh [13:04] not that bad [13:04] I leapt to the conclusion they were keeping shuttle flying. [13:04] haha if only, be a shame to see the shuttle go :( [13:05] In principle, in some ways yes. [13:05] In practice - shuttle is a hideous waste of cash that's basically only useful for pork. [13:06] yeah i guess, but if is probably the best feat of engineering in history so far [13:06] it* [13:07] i see nanosail status is updated, sband is on [13:08] The shuttle was the best feat of fucked up politics. [13:08] The whole design was basically driven around a wacky requirement to get support from the DOD. [13:08] unfortunately wherever congress gets a say in the budget its always going to be political :/ [13:09] That is - to launch a satellite into polar orbit, from a USA landing strip, and recover inside the USA without making more than one orbit. [13:09] This is what meant it had big wings. [13:09] that idea soon went out the window [13:10] Yes. [13:10] wonder when we'll eventually move on from liquid fuel to .. has to be a long way away still :( [13:11] Liquid fuel isn't the problem. [13:11] You can arguably get an order of magnitude cost reduction below what spaceX are projecting with liquid fuel. [13:12] i disagree, liquid fuel is .. well .. heavy .. [13:13] HOTOL :) [13:13] http://authors.library.caltech.edu/3303/1/PARaipcp04a.pdf [13:13] Is in principle another alternative. [13:13] Electric rockets.

[13:14] The same technology can power airliners. [13:15] lol upu good plan ! [13:15] SpeedEvil, as in regular commercial flight ? [13:15] NigeyS: Yes. You do need a regrettably large number of ground stations. But it's not really implausible. [13:15] At least for intracontinental flight. [13:16] hmm i guess, or we can just find a kill switch for gravity? :D [13:16] That would be nice. [13:17] yeah, escape velocity.. no problem, just kick me in the nads and off i go to space..lol [13:17] I note that at this time, nobody has actually tested that antimatter falls down. [13:17] you mentioned that the other day, can that actually be tested? [13:18] concidering the fact theyve only got 38atoms of the stuff for a few seconds [13:21] SpikeUK (~chatzilla@pdpc/supporter/monthlybyte/spikeuk) joined #highaltitude. [13:21] not yet. [13:21] It's actually really hard to test. [13:22] Because gravity is such a teeny force, compared to all the other disturbing forces. [13:23] yeah compared to the electromagnetic force gravity is kinda puny [13:25] im going to have to get a notams for this pico flight, extra battery = extra large balloon :( above the 2m limit [13:25] :/ [13:26] unless my gps will run on 2.7v which is highly unlikely [13:27] I'd say make sure you've got it connected right, then jumper the diode [13:28] i probably will, ordered another batt and the ftdi stuff so can get a better idea on what will and wont work tomorrow [13:28] :) [13:32] a single foil balloon might work better than the multiples, and still fit into the 2m exception rules [13:34] oh speaking of which guys [13:34] can you get spherical foil balloons [13:34] some radar guys at uni want a radar target they can put up on a tether [13:39] Darkside - Unlikely! Foil is made flat. Could make out of panels but it would be a sod to seal I should thing. [13:40] s/thing/think [13:40] yeah [13:40] damn [13:40] might have to hoist up some kind of frame structure [13:40] I have pondered a foil balloon. [13:40] And done some tests. [13:41] Hot-melt lap-joints work wonderfully [13:41] Are they looking for a reflective sphere? [13:41] with the barest smear of hot-melt, and the joint ironed shut. [13:41] SpeedEvil - ok [13:42] Though I suspect it may have issues at -40C - though it seemed fine at -20c [13:42] so maybe not [13:44] SpikeUK: yes [13:44] needs to be a sphere, as a corner reflecter is quite angle-dependent [13:45] A sphere sphere, or a lumpy sphere [13:46] you can get fairly spherical mylar balloons [13:46] yeeeeeah [13:46] I'm very unsure how radar reflective those woul dbe [13:46] a sphere sphere would be nice [13:46] we have a fibreglass target, which is a 1% sphere i think [13:46] whatever the measure it, it's good [13:46] but its too heavy, and too small [13:49] What frequency of radar?
