[16:30] plenty long enough :P [16:30] but not at very high average intensity [16:31] and then I see people doing one with a sole arduino on hackaday, pffft [16:31] though still most people seem to use standard RC transmitters and recievers, PWM control signals and standard RC brushless motor controllers [16:32] yeah i saw that [16:33] if i didn't spend soo much time on balloons i still want to make a mini robot for my flat [16:33] sort of like a mouse that drives around :-p [16:33] mod a roomba? :P [16:34] i think it'd need to be smaller - don't have that much floor space [16:34] pah tis a project for the future - still need to get atlantic halo in the air asap [16:36] hehe yup [16:40] DanielRichman (n=daniel@unaffiliated/danielrichman) joined #highaltitude.

[16:42] some one needs to launch soon :-p [16:42] yea I wanna try tracking from cambs! got a long audio cable for my radio specially [16:43] really need to hook up a long wire antenna to the hf input [16:43] lol so for the first three days after moving back up I was using my radio to listen to the local repeater and radio stations [16:43] Randomskk, i might assign you as lead tracker [16:43] signal was pretty good, S5 to S7ish [16:43] but it coudln't get all the radio stations one might expect [16:43] anyway three days later jonsowman comes up and goes oh cool [16:43] where's the antenna [16:44] and I'm like ".....in my box, still packed" [16:44] totally forgot to plug it in [16:44] hehe [16:44] so it was actually picking all the radio stations and the repeater up perfectly with just its antenna socket [16:44] of course once I plugged it in everything shot to S9+60 or so [16:47] Randomskk, hmmm or will you want to come along to the launch? [16:47] oh good point [16:47] can I do both? :P I can leave my radio on with the whip during the launch and come back and track with the yagi perhaps [16:47] or chase it, dunno [16:47] cause a key thing is we really need a listener from the beginning - seperate from the launch to catch that point when we move inside [16:47] I haven't actually seen a launch yet [16:47] we ain't chasing :-p [16:47] oh, yea, duh [16:48] tis a ballasthalo - they don't come back [16:48] hehe nope [16:48] well except via the postal system [16:48] come along to the launch - we'll find someone else - perhaps fergus will [16:48] will see what jon wants to do too, can most likely get something set up here [16:49] my window faces NW from selwyn, so I should be able to see straight to churchill [16:50] could probably borrow the room above mine to get a good few meters more height too [16:50] really needs a monitor [16:51] its cool we can borrow some local hams who will be able to get it early enough not to miss the handover between the launch team and the network [16:51] and if we set up your radio in advance then anything it gets will be even better [16:52] yea [16:52] will see how it is on the day [16:52] it should be a fun launch [16:52] could probably work something out with jon [16:52] but yea [16:52] should be easy enough to get some coverage [16:52] get the cuws shack to listen in :P [16:53] dunno if their steppIR yagi can do 434 actually, but quite possibly [16:56] at the moment i'm improving the float code [16:56] *float detection [17:00] jcoxon_ (n=jcoxon@host86-158-61-196.range86-158.btcentralplus.com) joined #highaltitude.

My (school) bus was 1.5hrs late [17:14] D: [17:15] what are peoples thoughts on time i should wait at float before dropping the ballast? [17:15] taking into the account that it takes a bit of time to truely settle into float [17:15] 20-30min? [17:15] Randomskk, i've had two days of school since we were due to go back on the 5th :D [17:15] what's the point of waiting? [17:16] sbasuita: also D:, in this case because I have no such no-school [17:16] though otoh also lectures still haven't started for me until tomorrow [17:16] on the other hand, SHIT, lectures are starting tomorrow I really need to do more work [17:16] russss, cause if not it'll dump every time it thinks its floating but not really [17:16] also I don't think heavy snow means cancelled lectures for me [17:16] true [17:16] not sure though [17:17] jcoxon: I take it any kind of uplink is more effort than it's worth? [17:17] although based on last time, if it thinks it's floating, it's probably within a couple hundred meters of the float altitude anyway. [17:17] Randomskk, yeah certainly at the range it might be at [17:17] russss, true but i want to see the change with the dumping of ballast [17:18] hence the aim to get it to float nicely [17:18] it's a fiddly one [17:18] but i'm going to add a timer as well [17:18] say after 4 hours sod it and dump something as we are getting bored waiting [17:18] well, I'd say that if you took BH3 and tweaked the float detection to be +/- 2m/s as opposed to 1m/s it would work [17:20] russss, 2m/s is quite close to our planned ascent rate [17:20] hmm [17:20] how are you changing the float detection then? [17:20] looking at the BH3 data we do eventually get a proper float [17:20] it doesn't time out as quickly [17:21] but to all intents and purposes it had been floating for a while [17:21] icez (n=icez@unaffiliated/icez) joined #highaltitude. [17:22] cause that seemed to be the issue - it would think it had lost float just before it dumped [17:22] yeah [17:22] well I would say cut the wait period to 10mins? [17:22] just to be on the safe side [17:22] because BH3 would have triggered given that [17:23] yes [17:24] ooh I might work on my telemetry processing/graphing thing on the plane [17:24] is the data from BH3 around somewhere? [17:24] yeah, one sec i'll find a link [17:25] http://www.pegasushabproject.org.uk/wiki/doku.php/missions:ballasthalo:ballasthalo3:flightlog [17:25] is the raw tracker data around anywhere too? [17:26] (including corrupt packets) [17:26] I forgot the URL for that page [17:26] http://www.robertharrison.org/listen/view.php [17:27] that's the one [17:27] buried in there [17:27] bonus badger2 data as well [17:28] russss, whats your graphing/telem plan? [17:29] well first I want to pull all the packets into a message queue, so anyone can attach and get realtime data [17:29] then I want to see if I can do any cunning error-correction if there are obvious single-character errors [17:30] :-) [17:30] would this one day be in a position to be rolled into the main server? [17:30] quite possibly [17:30] if you spoke with rjharrison he would probably provide access to the mysql database where everything is kept [17:31] well ideally the receiving script just needs to push the message onto the queue [17:31] oh thats easy then [17:36] I'm curious. how are you coding the detection of float? [17:38] blomlet, calculating the ascent rate and then when it falls within -1 and +1 over a period of time saying thats float [17:38] i know it could be more complicated and more effcient [17:39] Why do you care about float. [17:39] And not - say - descending.

[17:40] so i want to be able to show a big change when we dump ballast [17:40] how frequently are you reading the altitude? [17:41] about every 10 seconds (got telemetry in between) [17:41] actually more like 15seconds [17:42] ok - how lonk will it take to dump the ballast? [17:42] @long [17:42] not sure yet, need to run some tests [17:43] probably about 10mins for the whole tank [17:43] but only want to dump say 100mls at a time (500ml tank) [17:43] interesting. [17:44] :-) [17:44] Last in the line of interrogating questions... what %age of the payload weight is the ballast? [17:44] about 50% [17:45] this isn't a ZP balloon payload - tis a latex floater payload just to point out [17:46] gotcha [17:49] jasonb (n=jasonb@dsl027-180-244.sfo1.dsl.speakeasy.net) joined #highaltitude.
