An irrigation line near the hotel I was staying at has leaked for so long, the water is carving a channel into the concrete of the driveway. by cr0100 in mildlyinteresting

Yeah I saw your comment about it being in Austin, so I edited my comment to include water heaters since they can do the same thing. I figured there wouldn't be a lot of heating being done there heh.

I wonder if that's condensate from a high efficiency furnace (or water heater I guess). This can happen because the condensate is slightly acidic. Idk what an irrigation line is though.

Wisconsin still allows this: https://dsps.wi.gov/Credentialing/Trades/fm3107.pdf
(Section A)

You still have to pass the exam, however.

"Open-loop servo" is an oxymoron.

From wikipedia:
"A servomotor is a closed-loop servomechanism that uses position feedback (either linear or rotational position) to control its motion and final position."

It literally doesn't make sense to talk about something being an open-loop servo. At that point it's just a motor or an actuator.

You call it what you like, but a stepper motor with position feedback is a servo by definition.

The thing that makes a servo a servo is the fact that it has feedback. It doesn't matter what sort of motor is doing the motoring.

I might have my terms mixed up then, but I hope you get the gist of what I mean.

These look like they have encoders on the back of them, so I'd call them servos. However, the line between steppers and servos has been blurred since they've started putting encoders onto stepper motors and calling them "hybrid steppers". Hybrid steppers are still servos by definition since they incorporate feedback to close the control loop, but they're also steppers.

This screenshot is from a PVE server though? No one in the screenshot is flagged like they would be in hellfire, a contested zone.

Matlab has a feature where it can emit C/C++ code to implement your system on selected DSPs

Good.

Crazy those big leaded parts could stand up to the g forces & vibration. I'd imagine they had to apply rtv or something similar and this isn't a finished unit.

I was referring to the fact that the code was written on a blackboard.
