[21:48] I have previously posted my other interpretation of the act which is much better in that regard. [21:49] I think it's quite legal to tie strings to several model aircraft, put on roller-blades, and drag yourself around the sky on a parafoil. [21:49] - requiring no licence and having to obey almost no rules. [21:49] Lunar_Lander (~kevin@p54888CDB.dip0.t-ipconnect.de) left irc: Ping timeout: 244 seconds [21:50] I love you guys.

[21:59] amell: I think all the lightweight pico trackers are custom made by the person flying it. [22:00] ok. shame theres no boards about. I don't have patience for designing the boards. [22:01] if you want a lightweight tracker then the only real option is design it yourself. [22:01] you can start off with slightly less lightweight using something like arduino/ ntx2b/ ublox breakout. [22:02] I've seen that board before [22:02] thats the old one amell try this one : http://imgur.com/a/j4wE6 [22:02] sadly mfa298 is correct [22:03] if you want a super light weight board you have to put the effort in and design it yourself [22:03] thats lovely board, but i don't have smt oven etc. [22:03] the previous one you linked you don't need one [22:03] the one I just linked you probably do, though you could do it with a toaster oven and controller [22:03] http://imgur.com/a/bQXrk [22:09] UpuWork (~UpuWork@smtp.nevis.co.uk) left irc: [22:12] UpuWork (~UpuWork@2a02:b80:12:1:3919:a430:9ee1:345a) joined #highaltitude.

[22:24] ah [22:25] people generally want to keep their designs / bugs to themselves - most trackers also have slightly different goals (lightest/ lowest power/ solar/ new modes) which can't all be done with a standard board. [22:25] the circuitary for most of them isn't that difficult. microcontroller, gps, radio and possibly a couple of sensors. [22:26] phased plasma rifles. [22:26] amell sorry I won't sell that board [22:27] you need to design something yourself but really they aren't that complex [22:27] daveake (~Dave@92.40.103.217.threembb.co.uk) left irc: Read error: Connection reset by peer [22:27] daveake (~Dave@92.40.103.217.threembb.co.uk) joined #highaltitude.

[22:27] http://www.minicircuits.com/pdfs/LFCN-490.pdf [22:27] yes. its a nice board :) [22:28] tbh I don't think I could mass produce them [22:28] thats interesting aadamson [22:28] Upu, sure you could - http://www.goldphoenixpcb.com/ [22:29] i recall making a board at uni some 20 odd years ago. it was so tiny, about 1cm square and all the components were tight packed. [22:29] I've done a number of boards with this place, they purchase the parts from digikey and the rest is all turnkey [22:29] prices are very good too btw [22:29] well [22:30] but each has their own interests.... :) [22:30] it wasn't meant for mas sproduction [22:30] it was meant for me to mess about with [22:30] yeah that filter is used in a bunch of other stuff and I'm curious if Leo had taken a look at that?

[22:30] yeah, I know... just poking yah [22:31] minicircuits, oh they do lots of stuff in and around RF [22:31] the amp in the habamp is a minicircuits one [22:31] yeah, pretty typica.

[22:46] ah, so when you do aprs, you do it in 2mtrs don't ya... I keep forgetting that [22:47] dont know [22:47] power consumption probably goes way down too in that mode [22:47] Hey are using that filter on openLRS (long range system) for RC control, it's pretty much the norm there now [22:48] that uses 2 or 4fsk for pwm uplink and telemetry down [22:48] hey = they [22:48] oh dear ITLAC 01 [22:48] http://vimeo.com/87576347 [22:48] oh italian [22:48] lol the graphics [22:51] Spanish i think [22:52] daveake_ (~Dave@94.196.246.135.threembb.co.uk) joined #highaltitude.
