I haven't yet, the skin stays in place real well, cuz i frequently remove it to make servo adjustments and add other controls, ie eye movement and adding other anamatronic devicesStrider wrote:Hi. Could I ask what you used to attach the skin back on the skull?

Peristatic pump. One side connects to your alcohol bag, the other to your orifice. There are a variety of sizes and pump powers. Self priming, not complicatedBigBurrito wrote:Waiting fr this, the washer pump has no suckson, but this does, got 2 ordered

Add a small heating coil of some sort. Not to hot to burn your junk or anything, but just warm enough to keep the lube liquid and moving. Be careful about how you operate that thoughBigBurrito wrote:I have the pump installed with suction, the other problem is that the lube tends to solidify in the lines, so a constant chore to flush out the whole system

An idea came to me while I was sleeping. With these electronics running inside a "sealed container", a lot of heat will be generated. Could possibly run coolant/ liquid through tubing to take away heat. The heat could be transferred to your lube line, arms, legs, anywhere.BigBurrito wrote:Got a USB heater that i may tryMaecer wrote:Add a small heating coil of some sort.

To remove more heat, you could create artificial lungs; your doll could breathe away the heat. Silicone/ plastic/ TPE balloons inside a vacuum, with a diaphragm to expand/ retract to have the lungs do the same. Would finally make nostrils functional on Dolls if you ran the inlet and outlet thorough the nose. Similar to human anatomy with the diaphragm setup. That would be sexy (Hot breathe on your neck), but difficult too. I get that would be super difficult, but I thought I'd share my thought.

Seeing your current setup, from the back of the head, there's no more room I could see for adding any more components. That's a really tight fit. Might I recommend this site:
https://www.robotshop.com/en/micro-line ... ators.html
They have small linear actuators that take up less space than those servo motors, and can connect to your existing linkages going to the eyes. Just a thought. And they have several other motor/ actuator types that you could use for moving your doll's mouth. Having a controller in the chest of your doll will be tough connecting your wires to the head.

This slip ring provides your build the ability to rotate without your wires getting jacked up.

6 wire version from Adafruit.
Google search for Arduino slip ring for other slip rings.
If you were thinking of adding blinking eyes, check this out.

With modifications, this could be adapted to your doll head. Hit me up if you got other form and fit questions. I gotcha back if you need

There's a time delay for Flexinol as you apply current through the wire; it's all about heating up that wire. Shaping for correct actuation can be tricky and many times I've had the wire break; they're pretty fragile. When I've had them working correctly on other projects, they worked well.BigBurrito wrote:Also been looking into using Flexinol muscle wire for finer face movements like the eyelids, mouth corners to smile eyebrow movement
You can bind several together to amplify the lifting capacity.
