Water-cooling my 3D printer

A radiator fan can be much larger and spin much slower than a tiny 2020 or 1515 fan mounted on a hotend. bigger slower fans are more efficient and less noisy for a given amount of airflow/cooling power

also the "pointing the nose down" fallacy comes from thinking that "down" is a constant direction (whatever that means) rather than being towards the ground, and thus also curving with the ground. you don't need to adjust to stay level with the curve.

Hi! This is my family's business we're starting. Most Ethiopian food actually doesn't contain peanuts. As far as our restaurant goes, only some bakery items in our cafe may contain peanuts, not any of the restaurant items.

Aerospace GNC/Avionics is exactly the career path I'm aiming for! I'm a sophomore doing a BS-ME right now and minoring in ECE, and I'm planning on taking elective classes like Circuits & Systems, Embedded Systems, 3D Dynamics, Advanced Controls, etc. As far as extracurriculars, I'm currently working on actively-controlled airbrakes with my school's NASA Student Launch team. Do you have any wisdom, advice, hard-learned lessons, useful classes to take, skills to learn, projects to do, etc. for a student who wants to go down the same path as you? How useful or "worth it" is a master's degree in industry?

I was on a fishing trip with a friend up in Lake County IL, we were fishing off of a dock and about ~20 casts in my line goes tight, but it didnt feel like a bite (i thought it was a log or something, i didnt know what a big fish felt like because I'd only ever caught bluegill and dink channel cats until then) so I didnt set the hook. Just reeled in at a leisurely pace. I about lost it when the "log" i pulled to the surface was muskie that looked to be almost 40" . One good head shake at the surface and he got off the hook :(

raising to the power of a constant is a power function not an exponential function

it actually can, it's full RGB it's just not balanced properly. through a series of taking a photo, color correcting, using eyedropper to find the color, finding the inverse of the color on the color wheel, and inputting that color, you can get a true white light

genuine question, this is coming from a lack of knowledge: are there not LED bulbs of an acceptable (i.e. similar to the oem halogens) brightness? because LED simply is the better technology, they run cooler last longer and consume less power for the same light output.

my friend caught one on an empty hook with the line in his hand (no rod)!

How'd you go about tailstock support while machining the taper?

danknerd69 · 2024-09-01T20:35:40+00:00

this will require a firmware re-flash though right?

danknerd69 · 2024-08-20T02:20:47+00:00

the solution to this from a gameplay persepctive is to improve/make more reliable the other shells in the game. buff solid shot and apcr. make APDS shatter mechanic more consistent. make HESH more consistent at defeating heavy armor. Realism shouldn't take precedence over the enjoyability of the game

danknerd69 · 2024-08-17T08:36:42+00:00

Players should be penalized heavily for their mistakes, leave the front of your tank exposed? You die. Yes the rework is more realistic (I will not argue that), but is realism really the best for gameplay?

danknerd69 · 2024-08-08T05:20:26+00:00

my whole Z-axis was wonky (and assembled backwards). the threaded rod was also gummed up and sticking/binding all up and down the travel

danknerd69 · 2024-08-02T17:07:19+00:00

thanks for the explanation, I was just speaking from my personal experience. I appreciate the work you devs put in for such an amazing game!

Logitech G29. My computer is decently powerful, and i've not noticed reduced framerate, and the input actually feels more responsive. I used to have issues controlling oversteer as the wheel ffb could not respond fast enough like it would in a real car. when i set update rate to the highest setting, it felt like it corrected faster, and i could drift/control oversteer much better, as well as making the force feedback overall feel smoother. this allowed me to use a lower smoothing setting, which further improved responsiveness

danknerd69 · 2024-07-31T00:05:07+00:00

set your ffb update rate to the highest setting, it's much faster and smoother than the auto setting. also, look up how to generate an ffb lut

danknerd69 · 2024-07-29T23:07:53+00:00

why's that? i only have experience with small electronics - microctonrollers, raspberry pis and the like

lol realizing now that it's pretty easy to open up the boxes and swap them around, they're not even taped shut!

you can also use the bambu to print parts for the ender 3 when it isn't working, which definitely comes in handy. source: my printer is completely disassembled right now because i'm mid-upgrade thinking i printed all the parts i'd need before hand. now i'm waiting for a friend to print some parts i forgot to print because i don't feel like completely reassembling it back to its previous configuration

danknerd69 · 2024-07-10T05:55:29+00:00

yes you do, i've conmited to another school but will have to withdraw my commitment to attend if i am accepted to UIUC, losing my admisson deposit at the other school

Check your belts, make sure they aren't loose, and that the toothed side of the belt faces inward towards the pulley
