I thought I would split this off from Kåre's thread about the Lynxmotion A-Pod as to not totally hijack it.
I'd go with a real R/C control link! Find one made for a Heli, more flexible.
Get 7 or more channels. I like the Futaba although Spektrum and HiTec are popular. One can get a Turnigy quite cheap as well.
Yes the Turnigy / Imax / Eurgle 9x, is a great radio.
Just be nice to hook it up to an Arduino and SSC for a hex or quad.
I brought several receivers and they have all been bind to the 9x, so I'm ready.
While I prefer XBees, I knew there are several people up here who would like to use RC radios to control their hex or quads. Also I know a few other people who are interested in these radios, so a few days ago I ordered a Turnigy 9x radio from Hobbyking, which has been packed but I have not seen if it has shipped yet.
I probably should have waited, as after I ordered this, I found out that they are about to release a new version(9XR): http://forum.flitetest.com/showthread.p ... he-Unoffic
The new version is supposed to have on it a bunch of stuff on it that I want, like: the connector to allow you to flash new software, back lit led... Maybe I got lucky and they are silently updating the orders and I will be shipped the new one. But I would not bet on it. So assuming that I get the old one and the new one is out soon, may have to order it...
Not sure yet where this will take me. Could simply use it as is on one of my robots, to get it up and running. Or may start off hacking the receiver and use the SPI interface as described in: http://www.instructables.com/id/I2C-int ... urnigy-9x/
(yes the name says I2C but it appears to be SPI).
While the transmitter board is not an Arduino but it is instead an Atmega64, which is a nice processor (64K program space, 2 usarts, 8 AtoD...) and there are several open code bases for this, such as: http://code.google.com/p/er9x/
which is based on: http://code.google.com/p/th9x/
and there as schematics showing the design of the board, it looks like a nice system to hack. Who knows it may be easy to do a hardware hack and replace the RC radio with an XBee...
Or depending on what I find, maybe will play around and build my own DIY board... This could be a good starting point for a DIY as you get a case, 2 gimbals, 3 more analog knobs, several switches and an 128x64 display, which aint bad. It would be great to find out that most of these components simply plug into the main board, such that I could simply add connectors to new board. Better yet, would be great if I could simply use their board and add some daughter board that added the XBee support.
Or maybe I will just punt
