Arduino-based Radio Control on the Cheap
hello all,
i'm relative beginner arduino , absolute novice @ interfacing radios. goal rc system sends serial data usb radio remote radio interfaced arduino. i'd cheaply possible. data rates need support packets once every 50 ms or so. full-duplex desired since i'd implement telemetry @ later date. radiated power or frequency aren't huge issues, i'd 100 mw or more.
my first thought xtend or xbee, since support digi active community, prices little more i'm willing fork project. next thought system 3drobotics: http://store.3drobotics.com/products/3dr-radio-telemetry-kit-915-mhz $86.
does have experience 3dr system or other reliable , cheap systems it?
p.s. amateur radio fair game; have ticket.

chinese portables cheap, rfm12b radio's (0 dbm) , there 1 more rfm23 put out 20 dbm. @ lower data rates become reasonably sensitive > -107 dbm rx... @ 100kbaud
and there old icom ic01'a , ic03's ? (220 mhz), bought handful of old icom radio's few years $60.00 or thereabouts, need electrolytics cheap
$3.30 here :http://www.electrodragon.com/?product=radial-electrolytic-capacitor-1uf-470uf-12-kinds-10pcs
and these work rfm22's here, $6.57 : http://www.electrodragon.com/?product=si4432-433m-wireless-transceiver-module-distance-1500m note there isa minor differencce in gpio0 , gpio1 information in rrfm22b library header file, it's 1 line change.
just in case, here nice gps $22.14, own older version , it, u-blox pc software works it, need ftdi adaptor.
yes, know buy ones, ones use these $9.95 : http://www.oddwires.com/ftdi-ft232rl-usb-to-serial-adapter-module-usb-to-rs232-for-arduino/
although these should work $5.95 : http://www.oddwires.com/cp2102-low-cost-usb-to-serial-adapter-module-usb-to-rs232-for-arduino/
some idea's , places buy parts too. (wa7ems, being renewed)
