the first rule of nuclear engineering is to have fun and be yourself

another victim 😔
gone to the big hackspace full of kind trans women up in the sky..
the lab boys are telling me they need even more estrogen to continue testing, they also say they need more lab boys because they keep turning into lab women
imagining cute little devices maybe with e-ink panels that show ever-shifting patterns based on an RNG algorithm with time as the seed, two (or more) people could have them any distance apart and they’d always stay synced
(my sapphic yearning gets channeled into over-engineering)
Polypropylene would be a beautiful name for a girl

I’m not putting any stickers with an rpi logo on my laptop, but maybe I should design a “my other computer cost $26.43” sticker with a cute graphic of a shitty (affectionate) ebay thinkcenter mini pc
the first laser cutter I used ~10 years ago had poorly translated software that would often throw the delightful error “softdog no same!”
I still think about softdog
an engineer friend of mine who designs press-molds for recycled plastic convinced me to visit their workshop yesterday :3
I got to knead the plastic like dough to make the patterns! so much fun 🧡
as a mechanical engineer you should be learning about machining to make machinists happy with your designs, and PCB design to annoy EE's with increasingly cursed mechanical board layouts 🧡
being a switch is when you enjoy being both the test subject and the morally dubious scientist, right?
black latex gloves may look hot, but their low chemical resistance poses a huge risk when doing actual evil scientific experiments
even intimidating and morally questionable women in STEM need adequate PPE!

@Xavier@infosec.exchange unless you’re looking for a (brief) career as a lab boy I’m not at liberty to tell you that
good: learned a reliable method of bonding steel onto glass
less good: said glass happens to belong to my phone screen
extremely “tech witch” sounding engineering problem of deciding between a drone motor or a hard drive motor to power a magic wand..
this got reposted on Bluesky, and someone actually messaged them 😭 I’m sorry SHENZHEN XIANGTIANZHONG TECHNOLOGY Co., Ltd. @ErinRose@chaos.social

I think this might be the nicest connector datasheet technical drawing I’ve ever seen? 😭🥺
calling out individual laser weld spots on the body?? pick-and place vacuum location?! example integration!! I am in love
OH: “the gay nerd self-doxxing website”
“what?”

The benefit of a cloud-based CAD program like Fusion is that the dev who introduced the caching bug that's been gaslighting me for weeks can read the passive aggressive things I've been writing in my private design notes c:
kind of a long-shot, but does anyone know of a non transphobic solicitor / notary public in the south of the UK?
I want to finally sort my GRC (I’ve had the paperwork ready for ~4 years..), and I’ve been ghosted by all the ones I’ve reached out to so far… 
huh, looks like it’s not the just hobbyist rocket engineers tearing gopros down to the pcb’s and strapping them onto rockets…
(most hobbyists don’t pay defense contractors to do it for them though)

you can tell everyone on the NASA broadcast team is over 30, because clearly none of them can hear the high pitch whine that’s been in the background of every stream recently..

Planning my next project is turning out to mostly be deciding whether I prefer bashing my head on the ceiling when in bed, or on the bed frame when using the machinery I want to fit under it...
the structural calculations are easy in comparison :(

@emily@fedi.uni.horse you could say you’re going to, and then never finish it - Vaporpadware :3

@flamingspork@tacobelllabs.net oh I’m absolutely putting an arming pin on this test setup - (temporarily) pivoting away from FOC drivers to standard ESC’s means it could very easily spin up to self-disintegration speed if the supply voltage was too high by a few volts
Replying to
@hypha@cafe.mycelium.locahlo.st they're just brushless DC motors, you can control them however you want within reason! their KV rating isn't ideal for this, but their (pretty standardised) form-factor and ease of sourcing makes them tempting
Replying to
@flamingspork@tacobelllabs.net that's the plan :3
hard drive motors are mostly a fun idea for a theoretical version with two independent weights that can vary their phase offset - for dynamically varying "amplitude" as well as speed
Replying to
@ohmu @flamingspork entirely dependant on the filters you pick! both of those have filter options rated for acid gas and aerosolised oil mist environments though, so I’d imagine most situations would be covered
Replying to
@flamingspork the 3M 7000 series full-face is pretty aesthetically ideal if you need eye protection - barely anyone can look intimidating with a half-mask and goggles on..
but if not, the transparent facepiece on the cleanspace 2 PAPR lets your test sub.. colleagues see your (evil) facial expressions, which can be nice

@kabel42 if I wasn't polyamorous *maybe* I'd trust my structural engineering enough to do that..
an important part of becoming a good engineer is learning to trick your brain into having the dream you get after you fuck up an entire week of work the night *before* you fuck it up

take me down to perspective projection city, where the near is large and the far is itty-bitty

@Foritus@toot.dusepo.co.uk I’m not sure what purpose a read-head could serve in a magic device like this.. but it could be fun!

@MisterMaker my post is a joke - manually checking all my design features aren't cached is less effort than dealing with the Autodesk forums
Replying to
@emily@fedi.uni.horse not sure! a slow spin-up wouldn’t really be much of an issue, but I’m not really good enough at MechE theory to guess at how much torque the required eccentric mass would need to stay at speed with friction / varying gravity - so I’ll test it c:
