[07:50] hi Guest33078 [07:50] we're not all in the UK ;) [07:51] Hi, I'm trying to find out more information about how to seal the weather balloon and attach a payload without it falling off or breaking the balloon [07:51] http://ukhas.org.uk/guides:sealing_the_balloon I saw this [07:52] I generally use some lagre-ish zip ties [07:53] Jasperw (~jasperw@212-98-44-230.static.adslpremium.ch) joined #highaltitude. [07:53] the balloon necks are generally very thick [07:55] how do you attach the payload do you loop the balloon end over and zip tie it and loop your payload in the sling/hole you just made? [07:57] i put a zipe tie on tightly, then tie the cord tightly above the zip tie [07:57] then take the balloon off the filler nozzle, and put a could more zip ties around both the cord and neck [07:57] a couple* more [07:58] a lot of the pictures line the balloon where they zip tie with like a piece of a garbage bag [07:58] is that a good idea to have some sort of buffer material? [08:01] it couldnt hurt I guess, hehe [08:01] but the filler neck is really quite thick, at least 2mm I would say on my balloons [08:01] you'd have a hard time damaging it with a zip tie [08:02] what kind of cord do you use? [08:04] I use bricklayers line - a thin nylon cord which holds at least 10kg [08:04] also it's fluro coloured which is nice :) [08:30] Upu (~Upu@ubn.upuaut.net) joined #highaltitude.

[09:24] nah [09:24] i sandwich it between the foam in the joints [09:25] nice [09:25] actually I think in that pic I actually forgot [09:25] so I put it on the outside of the foam, and just smeared a bit of hot glue over it with my finger [09:25] what's the knot on the left of the pic called? [09:26] hmm, I don't really know - basically just take the lines and fold them in half, then make an overhand knot with the folded end [09:27] here's another one, this one I put the lines on the outside with a smear of glue too: [09:27] http://projecthorus.org/wp-content/uploads/2010/08/IMG_3501.jpg [09:30] good pic [09:30] stilldavid (~dave@68-64-214-18.static.forethought.net) joined #highaltitude. [09:30] no problem with the glue melting into the foam? [09:32] i have a pretty sophisticated heat control system for my hot glue gun [09:32] basically I test it on a bit of scrap foam and if it's getting a bit too hot then I unplug the glue gun :D [09:33] excellent [09:33] it only melts the foam when it gets quite hot - there's a good range where the glue is melted but it won't mess up the foam [09:34] you're packing quite a bit of technology in there: http://projecthorus.org/wp-content/uploads/2010/08/IMG_3500.jpg [09:36] yes, that's a handheld radio that's been turned into a repeater :) [09:36] do you have problems with circuits touching and shorting [09:36] oh, I also use toothpicks in the joins to make them a little stronger fsphil [09:37] like dowels I guess [09:37] genius [09:37] Guest33078: those are all zip tied down on stiff foam blocks, it doesnt looks it bit it's rather stable [09:38] Nick change: Guest33078 -> A01 [09:38] there easier name [09:38] the silvery thing beneath that is an aluminium plate which acts as a heatsink for the TX module, as it gets a bit warm [09:39] (& batteries are underneath that, recessed into the foam) [10:04] m1x10 (m1x10@ppp089210151148.dsl.hol.gr) joined #highaltitude.

[11:19] hey m1x10 [11:25] hey [11:25] I think I figure it out [11:26] figured which out? [11:26] my 6 battery pack got empty ! after 1 week [11:27] 1 week of transmitting? [11:27] yeah [11:27] I think it will go flat much faster than that if you are transmitting at a heavy duty cycle [11:27] but you're using APRS right? [11:27] so it would be very low duty cycle [11:28] i had it last night working and logging and I sew that at 07 oclock it stopped. then I sew the logs and arduino was reporting 3.8volt ! [11:28] yes juxta I can transmit every 32sec [11:28] keep in mind that your GPS will be drawing ~40mA constantly unless you switch it off [11:29] during those 32 secs the avr is sleeping, the gps does not output anything, and the sensor dont are in idle mode [11:29] sensors are* [11:30] the gps will still be tracking though & using some power [11:30] yeah sure. [11:30] but seems thats its drawing too little [11:30] I wonder how long it will last with the ultimate lithiums ! [11:31] lithiums will give you around 3000mAh [11:31] each one? [11:31] yes, but you have them in series. so your total capacity is still 3000mAh [11:31] lol [11:32] we put them in series just to get the voltage we want? [11:32] yes [11:32] shit ! [11:32] I hope there is a heat output at least [11:32] I saw you're using the arduino's onboard 5v regulator, which is not really ideal - you're putting in 9v and using 5v, the difference is dissipated as heat [11:33] so you're only using a little over 50% of your battery capacity effectively, the rest is wasted [11:33] better heat! I have the radio above the regulator and next to the batteries [11:33] okay, i'm off to have some dinner, back shortly [11:34] juxta as long as it will last more than a week I think i should not worry about battery issues.

[12:33] I tried it and needed 3M [12:33] fsphil: the ntx2 has an internal resistance so you can make a potential dividor between one resistor and the ntx2 txd pin [12:33] I could place a terminal in each of my wifes hands and use her as the resistor but it may blow my payload weight design [12:34] each hand might be a bit more than 3mM [12:34] 1M6 produced a shift of 1000 but that may be because my module is different, It's hard to know w/o trying it [12:34] also you'd have to use software serial; the arduino hardware serial library isn't up to it [12:35] also I *think* the usart is really noisy but haven't done science to prove it yet [12:35] I just measured her shes 4M ohms :) [12:35] haha [12:35] afk walking the dog [12:36] I'm using software serial [12:36] well using Robs library [12:36] it works [12:36] just the shift is wrong [12:36] now afk [13:14] SpikeUK (~chatzilla@212.183.140.32) joined #highaltitude.
