I found this dual axis gyro (IDG-1000) and i'm new to gyros so if anyone could help me understand the specs more that would be helpful. the power supply voltage is 3 volts and it says the zero rate output is 1.23 volts. does this mean when the gyro outputs 1.23 volts that it is not moving. If so then is the voltage range go from 3-0 volts for both axis. the sensitivity is 33mV/degree/sec if i divide this into 3 volts and i get 90 steps. Can i then read this with attiny 26 8 bit microcontroller that will use a timer to control servo motors? If anyone has any better ideas or better gyros and microcontrollers i'm all ears.

Sounds all right.

the sensitivity is 33mV/degree/sec if i divide this into 3 volts and i get 90 steps.

So that's 45°/s full scale in each direction. Fairly low for R/C apps, I determined 300°/s was much preferable.

Yes I got the 300 version but I guess it depends what you want to do with it.

will an 8 bit micro controller be enough for the 300? or will it be better to read the gyro with a 10 bit micro controller and if so do you guys have any recommendations preferably c code or assembly. also i need a wirless camera with reciver and i see that most of you guys us the kx131 with airwave transmitter and receiver. I'm on a low coast budget, have any of you tested a lower cost set up that can reach 100 feet with a resonable clear picture? thanks

i was going to use a dual axis accelerometer to double check wether or not any movement has taken place. i know it should work with tilt but i'm not sure if that would work with yaw. Do you have any suggestions.

No it wont work with yaw, if you do a search on this forum there is a long thread about it somewhere.

okay so for yaw drift can i just turn on the gyro and not move it then redored the drift ouputs then set those to whatever the zero rate is so that i dont' get drift on the pan and tilt?

Hi =) so i got some free samples of the idg300 gyro now i just need some cheap boards to put them on. Do any of you guys no where i can find a board the fits a 40 pin QFN package that has leads going out from those 40 pins so i can connect resistors and capacitors. I do not know how to do pcb design. thanks
