TPU wall thickness for shoes in c/3dprinting

[–] lemmyman 8 points 1 week ago (2 children)

TPU that's been printed right sticks to itself extremely well

I've done many TPU prints that were stressed to hell and they hold up amazingly well. Like 2000 lb shock loads on little 2mm walls, hundreds of times, and not tearing or delaminating. Ninjatek Cheetah and Fiberflex 40D mainly, but others seem to hold up really well too.

Teddy Ruxpin's evil creator in c/outofcontextcomics

[–] lemmyman 4 points 1 week ago (1 children)

In the past decade sometime there was a teddy ruxpin reboot, and my wife being the nostalgic person she is really wanted to get one for our daughter, who was like 4 years old at the time.

But they werent selling them anymore, so she found a used one, and promised that daddy (me) would figure out how to get more stories on it.

Well guess what, by that point they'd already shut down the whole system to sell more stories, so my poor daughter was stuck listening to "have you ever thought about a PAN-DA" or whatever, over and over again. And I was the bad guy.

And now after several days of eating very little and subsequently not pooping, my bowels are suddenly annoyingly and frequently mobile and gelatinous.

Pneumonia or something (self.dull_mens_club)

My oldest kid was out of school a whole week with pneumonia a couple weeks ago. I got very little work done (no work = no $ but that's OK in the short term).

On Friday I got a fever, chills, headache, lots of coughing, and massive massive fatigue. Now getting very little work done again. I'm probably going to be at like 40% typical income for the month. Again, OK in the short term but I got goals and this isn't helping you know?

By Tuesday it was about the same level so I did a "telehealth" visit thing and they said, yeah suck it up and take some robitussin.

Last night I started hearing the sound of rice krispies coming from my throat after a breath. I think that's a pretty tell tale sign of fluid in the lungs.

So today I went to urgent care. They did a chest x ray but the radiologist was out and the doctor found the imaging inconclusive but put me on antibiotics anyway.

Hopefully I will start feeling better in a day or two. This sucks.

Wow I was thinking about that just the other day (I remember it as "BME pain olympics"). I wonder if it's still floating around out there? But TBH I don't want to know.

What book(s) are you currently reading or listening? November 26 in c/books

[–] lemmyman 5 points 3 weeks ago (1 children)

My curator (some might say wife) had me reading On Writing by Stephen King. I am definitely not a writer but I liked it and think his advice could apply in some form to a lot of creative endeavors. There are a lot of funny parts in the first section, and I liked the tone (I've never read a Stephen King book so I didn't know what to expect). I thought it maybe got hung up too long on his hit-by-a-van episode, but that was still interesting.

Now I'm reading How to become the Dark Lord and die trying by Django Wexler. The tone was off-putting at first (and it's almost like he shook a salt shaker of "fucks" all around the first 10 pages for no reason), but 40 pages in its either mellowing or growing on me and I'm looking forward to the rest.

Why did my PLA crumble after 6 weeks idle in my printer? (self.3dprinting)

submitted 8 months ago by lemmyman to c/3dprinting

9 comments fedilink

I left a spool of eSun PLA+ beige in my Prusa MK4 with Prusa enclosure, which has sat idle since my last print about 6 weeks ago. The enclosure has a PTFE filament feed tube that runs the filament from the spool to the extruder.

Today I went to change the filament, and it broke apart in several pieces, right at the ends of the ptfe filament feed tube. The filament on the spool itself - within an inch of where it simply separated from the broken bits - I can fold over 180° tight without breaking it. Even the several ~1" lengths of broken bits are similarly ductile.

Ambient humidity is something like 15% (per my filament dryer) to 30% (per my dehumidifier, which is idle because it's winter).

Any idea why this happened? I'm curious about maybe interactions with the PETG parts that the broken pieces were close to (that's the only thing I can come up with, anyway).

Benchtop current sense amplifier? (self.ece)

submitted 1 year ago by lemmyman to c/ece

5 comments fedilink

Anyone have a recommendation for a benchtop current sense amplifier?

Sure, there are current sense breakout boards and whatnot. But what I'd like is a convenient device that I can use to instrument a circuit and then monitor its current with my oscilloscope or logic analyzer (Saleae with analog input) along with other signals in the circuit.

Ideal features might be:

Banana jack inputs and outputs
Selectable range / sensitivity / sense resistor
Isolated measurement, so I can measure high-side or low-side currents without worrying too much about the common connection on my scope
Selectable or automatic power source selection, between circuit-powered and externally-powered

I haven't seen anything like this in a few targeted searches, and just wondering if someone has any suggestions I might have missed.
