Hello all, I am getting back in the saddle making robots now that I am moved into my new home and settled into my new job as a technician maintaining the Fiber Optics network in Chattanooga TN.
IM BACK !

Ezang's New Robot Head Video Project 6/15/2021
Here is the robot head video for 6/15/2021: hope you enjoy it. ---------- In this video I break down all the components...
Luis's Jd Is Getting A Car
Here is my prototype of the JD Shoe box Car. There is more info on how i will use it Here
Ericez's My Real Size Wall.E Have A Job As Sales Promotion...
finally my real size Wal.e out of the house and work using Ez-Board, although there is a little problem with the wheel...
Ok so I picked up titanium coated bits so I can drill through this 1/8th inch steel. Just so happens the outside plate of the gearbox is also 1/8 inch steel. I thought to myself that I could likely use the same screws to mount the play to the gearbox. I used the largest bit I had and I still need to widen the hole more for the bearing at the base of the shaft.
Shaft through the hole . I need to widen it out another quarter inch I think and I will try getting longer screws tomorrow.
Found the motor markings , RS775WC-9013
6-18 volts , so it says it is 153 amps drawn at stall and 20 amps nominal torque
This little motor is a beast!
Just take one of your Laser guns and trim it out !
I never realized those motors were so mean. What controller were you going to use?
I don't have a laser but boy do I want one ! It's on the project list!
Anyways I ran to harbor freight to get a titanium stepper but to carefully widen the area around the shaft to clear for the main bearing. The mounting holes were spot on except the last one was about one mm off , so I screwed down the plate and drilled out the last one as a correction.
I have a sabertooth 2 x 12 but I think I may play it safe and go with a different configuration. I have two h bridges off Ebay I picked up. I was thinking of running both L and R on the h bridge paralleled to one motor which should share the load and run cooler. When I saw the nominal 20 amp at max torque I was worried I might over heat the sabertooth. I will try the 2 x12 sabertooth first if I can find it in my electronics bins.
Just for today I am working to get motors mounted and connectors soldered onto the motors and I can go from there.
Ok round 2 , I need to do the other side and I will takes pics step by step in case anyone ever needs to surface mount a motor.
