I am emailing with Cliff. I am not sure where he is on it right now. I hope to get it moving again soon.
Any update?
Thanks!

These motors would make a nice looking Arm.
I hope to see them added to the product line soon.
The ball’s in my court. I have everything I need to build the boards, but I haven’t even built the prototype yet. We are way over budget on new products, so it may not be a reality till early 08. Just telling the truth here.
Early '08 is just around the corner. When your ready it will be cool!
I’d set as a priority to build a working prototype and start stress testing it, especially if significant $$$ is still to be spent on the project. I assume the final product will be somewhat similar the the below project, but with the controller and H-bridge made on the same board.
I agree! It’s good to know the project is still alive.
Just a question about using the Single H-Bridge - HS-5745 Servo Amp with the PGHM-04 as pictured similar to the link above. The HS-574S spec says it can handle up to 6 volts, but to get maximum torque from the PGHM-04 you have to run it at 12 volts. So do I just feed the HS-574S output through some MOSFETs to increase the power? Even if I do this, I can’t accomplish the 70 kg-cm achieved in the initial post on this thread (although the nearly 500 oz-in as advertised on the PGHM is a good start.)
So is that the best way to drive these gear motors through the H-Bridge or is there a better way?
The best way to drive the 12v motors is using a 12v rated H-bridge. They tend to be a little pricey.
did you guys really just necro a thread that’s been dead and gone for almost 2 years? come on.
