Chris, On your website, there is a picture of the mod you did to the sherline spindle speed control. It looks like you bypass the max-speed trimpot with an optocoupler.
Are you able to get from lowest to full speed with this mod? Is this a regular optocoupler? I understand you drive the coupler directly with the pwm signal without any rc filter or so. Doesn't this make the speed less stable? I was thinking about a solution like this, but would have put a rc filter to 'convert' the pwn to a semi dc voltage.
