DIY Servo Drive - Finish Line

[AbuTarif]

Okay ,DIY Servo --------- Hmmmm ,
Sound there are many threads with same title , but actually I've tried to find one (Not Lengthy) and clear to understand by beginners (Like Me ) and rich the finish line which I assume it would be the summery to build DIY Servo Drive ,

So any suggestions for the poor peoples

Thanks Iron-Man for the info
But could you please complete you favor and tell me which one easier to start : dsPic or UHU ?,and is both of them open source DIY and free , ?

I think you have a lot of experience dealing with servo

[Iron-Man]

What type of servo motors will you be using? The dsPIC for the most part is open source except for the PIC compiler. You will have to purchase pre programed chips for the UHU servo. The UHU can drive high power servos.
Therefore, you need to decide what your requirements are. Also, I forgot to mention Max-Mod's excellent work. http://max-mod-shop.com/
Its hard to say which one would be easier. The UHU uses through hole components, which are easier to place than surface mount. The UHU can also power higher power servos vs the dsPIC. If you can handle surface mount, I would go with the dsPIC for starts.

Hope this helps,

So till now no servo drive on the net is free 100%
As I understand from you that UHU & dsPic & YAPSC all of them are commercial , but if I need to drive only a small DC brush motors like 2 or 3 amp ,which one you advice

[Iron-Man]

The UHU, dsPIC & YAPSC are not commercial. For a small drive 2 - 3 amps, try the dsPIC. The servo amps are not "free" in that you will have to purchase the components, circuit board material and build the servo amps. Most of the work has been done, although some tweaking is still required. You can obtain a limited version of Microchip C compiler & IDE here for free;

You will also need Mach 3 or EMC2.
