			I want a cheap headless GCS that speaks to me (possibly via CB radio), keeps logs, and provides a convenient place for me to tinker with agents and such (development time) with a maximally simple setup at the field. I will probably want a build system (for reflashing firmware at the field) and integration with FPV video, but those jobs are for later.

			I started with a Raspberry pi (rpi) running debian squeeze, which is what I run on my field laptop, but that was a dead end. Ocaml on squeeze is 3.11.2 (with no backport available), and that version doesn't support ocamlopt on ARM architectures. So far I've learned that I should be on a wheeze-based distribution (ocaml > 3.11, supporting ocamlopt on ARM), and I probably want to utilise the hardware float so that means I'll move to raspbian next.

			http://www.raspbian.org/

			My plan is to mudde through and get it working, then publish an install script that makes the install process repeatable. After that I might look into packaging, but I don't know much about that (yet).

	~~= Current project: Lisa/M Quad =~~
	~~I am currently gathering parts for a my first Quad project, which also be my first foray into STM32 paparazzi. So far, I have accumulated:~~

	* Lisa/M with Asprin (yay!) and a JTag thingy.
	* orderd a [http://www.hoverthings.com/catalog/ VC-450] quad frame, expect to have it soon.
	* These [http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=121 1000 Kv motors], these [http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=146 30A ESCs], and these [http://www.rctimer.com/index.php?gOo=goods_details.dwt&goodsid=527 12 pairs or 10" * 4.5" counter rotating props]. I have no idea if these are any good, or even if they are fit for purpose, I only know they cheap.
	* 2 Orange DSM2 satellite receivers from HobbyKing
	* 900Hz xbees (international firmware, 915-928 MHz and power limited to fit withing the Australian ISM class licence)
	* a new design NEO-6Q GPS (will fall back to a LEA-5H if this creates problems), etc
	* plenty of lipos, picoblade bits and pieces, LEDs, etc.

	~~anticipated AUW ~1kg.~~

	The powertrain spec is similar to what most of the VC-450 setups on the RC Groups thread have, but I suspect that (on 3S lipos) those motors/ESCs will be slightly under-propped. My main concern is that the controllers won't be fast enough, expect I may need to replace them with something better, but given the size of this model it might be OK to run them a little slower. The props feel quite flimsy and I will certainly be balancing them well before I use them.

	~~I still need to acquire a DSM2 transmitter, probably a JR module for a Turnigy 9X.~~

	My plan is to build a robust and strait-forward quad, then learn to fly it. After that, I'd like to switch to 36 MHz PPM control (like my planes) or fly by joystick to free up 2.4 GHz for analog video. Then I'll probably move on to a smaller bespoke frame, I guess.
