Hi Frank,

Very nice job and a lot of fun to read about how you did it.

Hi Frank,

That looks brilliant! The 3D print looks very metallic from the photos. Looking forward to seeing it all come together - feel like watching one of the Oz movies tonight now : )

It's been ages since I read them : (

Is using the JQ6500 module something new for you or have you used it before?

The reason I ask is because I struggled with finding a replacement for the DFPlayer module. I failed to get the module I was looking at Looking for member insight into the JR6001 Serial MP3 Custom Programmable Sound Recorder Module working.[mention:dc11ece8204f479e8dce2a47a33b20d3:e9ed411860ed4f2ba0265705b8793d05] in his post JQ6500 MP3 Player gave me some hope there is a replacement.

I have some of the module on order. I'm hoping to have success with them. I was just curious how you came by the JQ6500?

Frank,

Filtering (or damping) the servo commands is an excellent way of smoothing out the jittery effects that can exist with servos and their mechanical linkages. This is particularly true where there is a high inertial mass being controlled. For my Skull client, I have implemented three levels of damping that can be selected, so that the movements are smooth and there are no undue stresses created on the servos or their linkages.

Your video of the eye movements look much improved.

Keep up the good work!
