Probably an LLM-assisted blog post.
- jihadjihad 2y agoYeah it really does read like something spat out by ChatGPT. They always have to include the word “key” for some reason.
- mda 2y agoIndeed, I see the word "key" in titles of many click bait LLM generated articles. Probably it is creating a self feedback loop now.
- dankwizard 2y agoI wish they added some LLM-assisted CSS & Div tags because this layout is atrocious.
- metal_am 2y agoIt must be. The part about minimizing the stepper motor power consumption is nonsensical. Steppers use the same current whether moving or stationary.
- addaon 2y agoYou can absolutely adjust the current for a stepper motor. Lower currents use less power, but have less torque, leading to an increased chance of missed steps. In a system like this, the motor torque becomes a linear force to move a belt — and the force required to move the belt depends on if a piece is moving with it, and which piece. It’s perfectly reasonable to bump up motor current when moving a piece, and bump it down when moving just the belt to grab the next piece.
- dymk 2y agoOnly the most naive stepper driver will drive a stationary motor at full current
- _flux 2y ago> Steppers use the same current whether moving or stationary. You can turn off the power when you're not moving it, assuming it doesn't need to hold anything in its place (like in this application). E.g. https://www.allegromicro.com/-/media/files/datasheets/a5984-datasheet.pdf https://www.allegromicro.com/-/media/files/datasheets/a5984-... describes how its current control in general works for this stepper motor driver in page 9 (certainly not using the same current always) and in page 12 how to use its ENABLE signal to control FETs and SLEEP to further reduce power usage.
- throw_pm23 2y agoThat's an immediate disqualifier for everything (for me) unfortunately.
- alykhalid 2y agoI would suggest keeping an open mind. I use LLMs to check, my writing and if could be could improved. English is not first language and I am not confident enough to know if what I wrote comes across professionally or not. May be the author of the blog post has the same issue.
- throw_pm23 2y agoEnglish is my fourth language and I much prefer reading something that is imperfect but written by a human to something auto-generated. That feels as if we someone would say "I'm busy, talk to my agent instead."
- seplox 2y agoThis comes across a little aggressive and braggy. Perhaps a better way to write it would be: > I much prefer reading something that is imperfect but written by a human to something auto-generated. That feels as if we someone would say "I'm busy, talk to my agent instead."
- evoke4908 2y agoCondescending to someone who speaks your language as a fourth language about their tone comes off as extremely rude and superior. A better way to write this would be: ""
- RIMR 2y agoI'm not certain that this blog post is the original. The bottom of the website has contact information for the author, and the hyperlinks for the email and phone number link to different emails and numbers than are listed on the page. Section 2 has the words "Mars Science Laboratory" (the official name of the Curiosity Rover) printed vertically to the right for no discernible reason. It's almost as if this were a patchwork of content from multiple sources, maybe glued together by an LLM. It's hosted on a free hosting platform with no chain of custody. The author is only known as "Tamerlan". Why wouldn't an engineer have their own blog for a project like this?
