Showroom BOSeTAMPER 's Compact Steward Rotary Servo 6DOF SMC3 base for Go Kart (Complete)

Thank you. I was planning on using it as a simple analog output, just like the 3 wire hall effect pots I’ve been using. I could also double the voltage pretty easily with opamps. One of my hobbies is designing and building analog synthesizers so I have hundreds of opamps. That way you can actually adjust the output magnifier (or decrease) factors on the fly with trim pots. I was trying to be a little lazy and use the voltage output directly without any code or mods. But your suggestion is valid and much appreciated

Thank you for the quick reply. You’re a really good resource here. And your espresso tamper is very slick!

You can use it as 'analog 3 wires' exactly like a rotary potentiometer. This is the way on my setup, literally like a drop-replacement to a potentiometer.

In regard to simplicity, I don't think you need to add an op-amp at all. Just program it on the chip, or just change the value on the SMC code line, to get the full scale while physically moving less than a full turn.
But if you want to have fun in adding op-amp, that is great

AnalogRead()

Will give you a number between 0 and 1024 for 0 to 5v

The 0-180 degree sensor will give 5 v at full range

A 0-360 degree sensor will give 2.5v at 180 degree rotation

So when you do the analogread() just multiply the number x 2

This is very helpful, thank you so much. It's a great group of people here, knowledgeable and helpful.

I use wheel chair motors in a 2 DoF sim. They came with a 36:1 gear ratio and it functions fine but you will feel the gear backlash. One downside of the cheaper motors.

But very interested in your build, thinking of also trying a 6 DoF using wheel chair motors.

yes, they work great with the cheap IBT2 controllers. As long as you improve the cooling shortcomings on the IBT2s. I add fins on both sides of the board and use 24V high flow fans per 2 controllers. I will keep the group updated. Here’s a few pics. Those motors are CM808-110B. Heavy duty versions. eBay seller Xi’s sells them for $35 each free shipping in US
Power supply is 1500W 24V for 2 motors, total of 3 for the 6DOF build

That fan set up will keep the IBT's nice and cool.

What is the max current rating of the power supplies?

1500W at 24V so max is about 62A for two motors. Although I would not trust anything beyond 50A continuous per power supply. I have 25A blade type fuses going to each motor, just in case
