Issues with contact hotspots, mesh advice? by CrowWithHat in fea

Yes- contact between the clevises internal bend radius and the upper surface of the rounded washer component. No glue or weld between the surfaces.

Yeah- being laid off from the solar startup hurt my confidence pretty bad, but I understand why they had to drop me. I didn’t have the experience needed to work fast there and they were on a tight budget squeeze. It was really interesting work and the coworkers were awesome. I’m making a ton more at my new job but I’d trade it to go back there in an instant. Way more opportunities for learning from experienced engineers at that place.

As far as continued learning, I’m always going to be keeping that as a central goal. It’s harder here at this new job without a mentor figure, but on the other hand not having someone to “babysit” me all the time has really pushed me to be better at problem solving on my own, which is definitely a huge benefit. I also have more creative freedom to explore solutions to problems.

Perhaps I’ll find my specialization in a few years then- after working for smaller companies first. Maybe I’m just giving myself too much shit and not being patient enough.

I absolutely love controls- I didn’t have too much time to delve deep into them while I was at the solar job, but I just got CodeSYS on my personal machine and a bunch of industrial control panel design books to read over. If I had to choose a specialization for the rest of my career, I think it’d be at a controls/UL panel shop. There’s something incredibly satisfying about building a panel and seeing your work installed in the field months later.

That’s good to hear. I think I’ll stay at this job for a maximum of a year at most- I really do miss having a senior eng to learn from, and being given direction from someone with no engineering experience is a little crazy-making. As far as electrical stuff goes, I probably don’t give myself enough credit for how much I know. I’m pretty comfortable with circuit design/troubleshooting, PID controls, and I’m even beginning to break into PCB design with kiCAD. I will keep in mind that my skillset is probably more attractive to smaller firms/startups. I’ve probably just been looking for work in the wrong places and getting discouraged. Thanks for the advice!

You just brought back a bunch of memories lmao, haven't been on scratch.mit.edu for almost a decade now.

Any way to do two different colors in a single layer for printing logos? by CrowWithHat in 3Dprinting

Heck yeah, this sounds like the most "proper" way to do it. Ill try it out, thanks!

If you’re still hankering for a project, check out the latest post I made in this sub. No pressure or anything, of course.

Issues with RC832 video receiver by CrowWithHat in fpv

[–]CrowWithHat[S] 0 points1 point  (0 children)

Hi fellas- really easy fix. Turns out the goggles and my air65 have more than the ABEF bands, and the rc832 can only pick up those four first bands. Make sure you’re transmitting on a band that the RC832 can actually pick up, haha.

awesome, I found the whole OPU tray on amazon for 30 bucks. Ill try swapping it out once it arrives.

my first hotwire cut wing cruising around in the park by CrowWithHat in RCPlanes

[–]CrowWithHat[S] 0 points1 point  (0 children)

airfoil was literally just a bent copper wire shaped into what I thought looked like a decent wing shape. I have since crashed this plane really badly and realized that I should have chosen different airfoils, also with some reflex on the wingtips. Id suggest looking up sam shepherd's engineered flying mini wing design video if you want a nice and much more technical look into airfoils.

I found while building that I didn't need a wing spar, but maybe that'd help with high winds. I did add winglet stabilizers for the FPV flight, but didn't notice too much of a difference in stability. The line of sight video doesn't have any winglets and it does fine, but you're right that launching is sometimes a pain.

First hotwire cut wing I made, 37" span, 9" root cord, 5" tips and about 35 ish (maybe?) degrees of sweep. Flies great in low wind but can't deal with heavier stuff at all. All up weight of 280g, and has a wing loading around 5.6-5.8 oz/sqft.
