(...) You probably mean the Sharp GP1U5x. That one is modifiable so that it can be read like an analog signal. If anyone can direct me to a company in the Netherlands which sells these parts, I would very much like to know. Thanks. (...) ***...*** * (...)

Ideally, I could use an H-bridge on the same board as the "new" electronics and provide expanded feedback such as current sensing or encoder in addition to the normal servo interface. It would also be nice to allow PWM to control the power presented (...) (26 years ago, 19-May-98, to lugnet.robotics.handyboard)

Thanks, I was going to use a pad/hole size of .050/.028. The default size of my library uses .050/.025. I checked some pin size data and it shows .015 (min) to .023 (max). Allowing .008 to .010 extra and .003 for plating, it seems that the best size (...) (26 years ago, 18-May-98, to lugnet.robotics.handyboard)
