INS module moving from mc6811 to avr8
OK, I’ve bitten the bullet and started playing with an avr8 board!
I bought an 8MHz Pololul "Orangutan" (and programmer) some time back, and until now havn’t had a decent project to plug it into. But monitoring a few PWM sensors, doing a small amount of filtering and plugging into a USB port may be it.
But with "only" 1K of ram, it may be pushed to be much more than a gateway between one of the avr32 boards and the sensors involved. But it does have 16k of flash, so the s/w can be pretty ’sfisticated.
The basic INS filter I was playing with this past couple wks is only about 8K of 6800 code (i.e. gcc -Os/-O2).
For those interested in such things, the approx 2" sq board also has 8 10-bit a/d, a 2-line LCD, a few buttons, a LED, a knob on ad7, a buzzer, and 2 1A motor channels.
It seems like Pololu are moving in the direction of larger robots, so the price has dropped a bit since I bought mine. I noticed a package with an "original Orangutan" plus its controller is now under 70 usd for unit qty.
I orderd one of these a few days ago, Wiring I/O Board http://www.maximumrobotics.com/store/p/881-Wiring-I-O-Board-ATMega128-Controller-Board-.aspx, Still waiting for delivery but looks like a great ATMega128 R&D board.

PS! Who deleted my posts?
Ahh…. 4K of ram.
Looks like a good deal.
Looks like a neat wheelbot.
Yes, have had some experience with kits that require undocumented “adjustment” before they can be assembled, let alone work.
Still, that’s why the toolbox includes a set of files, hacksaws and glue-gun.
(Ash: yes, I did buy a Dremel, but in my hands it’s mainly a force for uncontrolled destruction).
Haha
Does anyone actually "make" things with a Dremel?
It’s more like a universal "make-the-bit-that-doesn’t-fit–fit" tool as far as I am concerned.
I still don’t have a glue gun yet which is the other part of the equation of course….
Glue guns fix what dremels brake; “Hmmm don’t think I should have cut that bit of…”
The kit is a very good idea, but it has many flaws, will take a few days to assemble and modify, with email back and forth to Carl, I would not recommend anybody else getting one just yet.
Hey mate, looking into your post problem now. I haven’t touched em!
XMAS has come early, http://www.phenostream.com/products/KIT_01.aspx and the wiring board has arrived. Will assemble the AVRKitCar first, then play a bit with the wiring board this weekend.
