Heya! Finally I received the plexiglass window so my MBFM is really completed. I want give thanks to TK who shared the results of his great work with us...to SmashTV with his "speedoflight" shipping and Wilba with his effort in chips finding ( and shipping ). A special thank go to Flemming for his psicological support to me during the parts and materials waiting ( that for us seems always too long ). regards Antix

Hi all 1 step jitter for 7 bits (128 value) is huge !!! it's more than 40mV for 5V supply, there is for sure and issue with your build. Keys for low jitter: -A perfect grounding, with same 0V reference for both servo and AD chips Vref -Quality power supply with low ripple, good line and load regulation, optional sense is a must -shorter wire as possible -optional low pass RC filter can be added Following all this for my build, running AIN at 11bit (2048 steps) give very low jitter, less than 1 step value change per sec, around 2mV jitter. So the system is finally configured at 10bit ... rock solid ! Best Zam

And panel is in, everything fits!
