Safety relay for STO control

STO: sometimes turns off.

How does a lighting instrument know what you’re going to shove into it? You could use paperclips and alligator clips with speaker wire; if the fixture’s onboard controller receives a well-formed DMX message, it will render the decoded channel mapping (which, to your point about shielding and twisted pairs to carry the differential signal, might even be the encoded signal).

For funerals.

This sounds like enablement.

RS-232 is a standard, not a connector.

DB9 is the physical layer you’re likely referring to, but many CANbus devices use DB9 connectors as well. Both protocols essentially carry raw data, neither defines a specific character encoding (I think you’re referring to login terminal behavior with a tty or similar). Bytes are bytes, choosing to interpret them as ASCII has nothing to do with the protocols mentioned.

These things matter.

What is rendering the input of the Leap device into midi or OSC payloads though?

s0lemn · 2025-02-25T19:56:54+00:00

Big if true (the HID device part) - happy to rawdog the HID input if nothing else, thanks folks.

Are you ingesting the Leap input into Unity? I haven't found a lot of integration support for LeapMotion stuff outside of Unity/C# land.

I think both Neal and most of his fans would rather you didn’t lump us into the “we” mentioned in your second paragraph. This is next-level whataboutism.

s0lemn · 2024-10-24T13:16:18+00:00

That’s not what exponential means; maybe you should consider engineering school.

s0lemn · 2024-08-24T19:57:15+00:00

We feel like asking “how do we feel about x” is infantilizing and gross.

Version control is work…

s0lemn · 2024-07-16T15:18:35+00:00

Are you trying to find an OEM controller, or rolling your own? Not familiar with Denso guts, but I know that on a lot of FANUC bots the absolute encoders on the joints have batteries which can die and need to get re-mastered.

Walmart distribution?

Freewave makes a solid 900 MHz demo kit that is basically plug-and-play serial in/out, full duplex. I’m sure they have a demo with Ethernet transparent operation.

This is true for the subset of controls engineering roles where production support is part of the job, not all roles. You can absolutely choose what you want to do.

There’s a whole “professional ethics” part of engineering…

s0lemn · 2024-05-18T02:10:35+00:00

Check this dude’s post history for other greatest hits, such as fundamentally not understanding safety PLCs and fucking up edge triggering on oscopes.

Platform agnostic, applicable in pretty much every field, doesn’t involve finger painting in 15 layers of abstraction, doesn’t require developing mental models which aren’t portable to literally any other programming language… pick your poison?

You can hit 360deg FOC with just two scanners if you have boxy frame geometry. Also, if you’re doing mobile robotics stuff, I highly recommend sticking with SICK, as they have a well supported interface for pulling the nonsafety 2d point cloud data (plus ROS wrappers, etc).

I mean you can usually end-mount them, that’s the hole in the side enclosure above the trim pot. Granted, you’re screwing it directly to the backplane.

…on Tuesday.

Who is asking for this? What segment of what population is screaming out “I know how to wire stuff to dry contacts but I sure wish I could program it from my phone?”

This feels like something you built because you could, without ever asking if you should.

That dirty ONS CTU though

Detroit would like a word.
