It's just a concept right now but I wanted others to see that the scale doesnt quite match. Right now its just stacked on there and neck is a little too long.

SFOY what AH is your batteries LI-POLY same as SLA just depends first on current ouput and way its charged,SLA needs CV constant voltageon LI-PO is needs CV constand voltage and CC constant current to charge them,on LI-PO they are much lighter ,less then half of SLA on charging LI-PO they dont dont last to long,but on SLA last a lot longer so on each batteries there are a good side and a bad side using a lighter battery will have less drain on the battery because of less torque on the motor
JOSH it fairly easy to make a circuit to charge LI-Poly all you need is 2 LM317 regulators ,one set as a current source other set at a voltage source,the regulator will be both the current source and voltage source stable can easy make packs ,but for each one need a special switching circuit ,witch ebay has the board,and temperature circuit if you need a link to the special switching board can post the link
I'm finally settled in so it was time to fiddle with Pinhead. I did some rewiring so that there were fewer wires running up the neck. Before there were all three wires going to each of the facial motors. Now I have a single ,slightly thicker, gauge ground and power wire and only signal wires from ez-board. After that I messed with the joystick control for head tilts forward/back/side to side/neck rotation. Also programmed a button for eye blink and mouth open and close. I'm having trouble with the x axis on joystick 2. Windows shows it working but the little dot on the joystick ez control panel doesn't move on the x axis. Maybe I will figure out what is the problem and post a short vid of his quirky moves. An EZ puppet.
GOOD to see you start back working on him,this week i will be putting my frame peices together and post photos
Cool. Just post them on your project page though.
I KNOW
I was only admiring this one last night, I love this head! If only more come up on ebay over here, I guess an alert needs to be set
Rich, that's exactly what I did to get mine. I saw one for Josh at a steal a while back too. I think Josh once sent me a link to where you can get them new or it could have been Sam (Sfoy). I will try and find it again. UPDATE I found the link but I'm sorry it no longer available. Here is the link anyway if it comes back. Old link
Yea its a cool head and it fits inside robie sr helmet too as well.
