[17:03] looks good geoff [17:05] Cosmic rays and cameras ? http://aer.aas.org/resource/1/aerscz/v9/i1/p010111_s1?view=fulltext can be a problem! [17:07] I think it's mostly not an issue because the sensor is small. [17:07] So you very rarely get a hit. [17:08] Of course at altitude that rate goes up quite a bit. [17:08] Might be interesting at the greater heights, where the shower will be more engertic than lower down, but I don't think it will be vast problem, most rays will pass thru at right angles and only affect 1 or 2 pixels in most cases [17:09] Well, the energy of the particles basically doesn't matter. [17:10] my video had less spots and streaks higher up [17:10] (and indeed, I don't think the energy changes a whole lot with altitude, until you get really high) [17:11] lz1dev (~lz1dev@46.47.80.192) joined #highaltitude.

[17:14] I would imagine there is a cross-over between count of electrons released in the sensor due to energy as opposed to count of electrons due to larger shower at lower heights ? [17:17] Well, if there are more cosmics (larger shower) you just get more hits. [17:18] The muons are probably minimally ionising, so their signal won't change much with their energy.

[20:10] hi OZ1SKY_Brian [20:10] yes its too far north for us danes, so need to get some LAs [20:10] hi lunar [20:10] May have exceeded the maximum of 2500 queries per day to the google elevation API [20:10] LA3EQ is the best bet [20:11] fyi http://oz1sky.smart-tech.dk/hab/Coverage/northsea.html [20:11] my line of sight calculator script isnt very efficient [20:11] OZ1SKY_Brian, https://www.youtube.com/watch?v=Q56BkA-E-_k&list=UUwLbAytnYpEVbryZurOL8cg&index=1 [20:12] OZ1SKY_Brian, we'll have some warning about if it'll even get far enough along the flight path [20:12] so don't need to rush [20:12] you need someone up in the aberdeen area [20:13] yeah, we can do that [20:14] http://wiki.ukhas.org.uk/projects:picoatlas:picoatlasvi#flight1 [20:15] ah yes theres one [20:15] evening all [20:15] evening Anthony [20:15] i think teh best plan is to get it to float [20:15] evening Upu [20:15] then we can attempt to recruit listeners [20:15] the early bits should be well covered [20:15] yes thats a first, james [20:15] nigelvh, you asked about the wires in the payload? [20:15] OZ1SKY_Brian, will be launching at 1500 on saturday [20:16] Upu, whats better for this 2xAAA or 1xAA? [20:16] 1 x AA [20:16] jcoxon who is that one up near aberdeen ? [20:17] Upu, do you have seven minutes :)? [20:17] Upu, despite more efficient? [20:17] seven ? [20:17] yea [20:17] no sorry only got six [20:17] XD [20:17] not more efficient on 1.8v board [20:17] is on 3.3 [20:17] BrainDamage (~BrainDama@dynamic-adsl-94-36-246-171.clienti.tiscali.it) left irc: Remote host closed the connection [20:18] Upu, https://www.youtube.com/watch?v=Q56BkA-E-_k&list=UUwLbAytnYpEVbryZurOL8cg&index=1 [20:18] BrainDamage (~BrainDama@dynamic-adsl-94-36-246-171.clienti.tiscali.it) joined #highaltitude.

[20:19] Tescos :) [20:19] hmmm 3xAAA + payload is 32.3g [20:19] :-p [20:19] okay [20:19] will find some AAs tomorrow [20:21] oh James [20:21] https://dl.dropbox.com/u/63720513/Images/HAB/max7c.jpg [20:21] oooo [20:21] thats exciting [20:21] jcoxon: there's an RF22::reset() fucntion, yet you use the digitalWrite(RFM22B_SDN, HIGH); followed by digitalWrite(RFM22B_SDN, LOW); in your pico94 code to reset it [20:21] what sort of benefits [20:21] jcoxon: is it more reliable? [20:21] no idea [20:22] not had chance to test it yet [20:22] 10Hz updates [20:22] costyn, well i'm turning it off completely [20:22] ok [20:22] allegedly 4.5mA in 1 sec cyclic [20:22] sounds like what I need [20:23] btw [20:23] stupid question [20:23] Action: eroomde braces himself [20:23] why are AAAA batteries called that way if they don't look smaller than AAA? [20:24] Lunar_Lander nice video, but the antenna worrys me [20:24] yea [20:24] I was told to put straws over the wires [20:24] because they're not AAA? [20:25] yea I mean AA is bigger than AAA then I thought AAAA is smaller than AAA [20:25] have you just pressed the dipole into the centerpin of the bnc connector? [20:25] no I soldered it on [20:25] ok good [20:28] got the remote working on the radio on intranet, but for some reason not on the internet, will look into it [20:29] but should get it working for your flight, as im not home when you launch [20:29] yea [20:30] :) sounds good [20:30] its abit tricky to route to the car :-) [20:31] Upu: Nice board :) [20:31] but should be able to get it working [20:31] you can buy them Gadget-Mac :) [20:32] not with the MAX7 on [20:33] who need pictures, when you seen it in real life :-) [20:33] on a short turnaround though :-) [20:33] :) [20:34] Upu: Is the max7 the same footprint [20:34] yep [20:34] Assumed it would be, but nice [20:35] G8KNN-Jon (~Jon@cpc1-cmbg10-0-0-cust144.5-4.cable.virginmedia.com) joined #highaltitude.

[21:33] yea noticed you had A5 intermingled with RFM22B_SDN [21:35] costyn, i've updated the code again [21:35] that really made a difference? [21:35] who knows [21:37] jcoxon: thanks [21:38] jcoxon: weird, just broke it again by making the delay slower. your wait function is basically the same as delay right? [21:38] whats your speed? [21:38] 8 I think [21:38] is that wait ? [21:38] wait(); ? [21:38] if you're on 8Mhz use delay [21:39] yes, I'm using delay [21:39] I wrote wait as delay doesn't work on 4Mhz µC [21:40] but tbh I wouldn't use it for anything where timing is crtical like rtty [21:40] critical [21:40] Upu: ah [21:41] Dutch-Mill (3e2d87d7@gateway/web/freenode/ip.62.45.135.215) left irc: Quit: Page closed [21:41] Boggle (~Jon@81.102.132.145) left irc: Read error: Connection reset by peer [21:42] Upu, how is work going?

[22:28] it can do both, but it will still assist the signal [22:28] I copyed PYSY on tropo assist, it was below the horizon here [22:28] 802km range [22:29] whether or not [22:29] depends on the angle of atack, on the tropo layer [22:30] too steep and it will pass, and too shallow it will bounce off, in between it will get assisted [22:31] so no way of saying for sure, all i know is that in most cases it helps.
