Thanks for the answer Richard.
I'm not very experienced with electronics and microcontrollers, so, sometimes I cant understand, or take much time to understand... also my english is not very good. I think I proposed something, but I missed to give more information on what I need. I want to use two HDD voice coils from an old drives to create a laser XY scanner. I think it dont need more than 10 ~ 16 bit resolution. At first I dont want something profissional, something simple is ok. I was thinking in some circuit that controls the HDD head by itself, also the feedback, the microcontroller just sends a analog value of the position. Is this ok? What the name for this type of circuit? But, if you think something driven by the microcontroller, also feedback, will be ok for me too. If you have some idea, please tell me. Thanks. |

| Maybe it will work ... or maybe not. | 01/01/70 00:00 | |

| It's not as easy as one might think | 01/01/70 00:00 | |
| harder than I thought | 01/01/70 00:00 | |
| There are ways ... | 01/01/70 00:00 | |
| speed is essential when drawing | 01/01/70 00:00 | |
| Yes, faster is better in this case | 01/01/70 00:00 | |

| That would likely work | 01/01/70 00:00 | |
