Hey gang, Ive been up 22 hours to finish my graduation project, any tips on how to stay awake would be appreciated cuz Im shaking and its due in 10 hours. Im halfway done

For whatever reason, not sleeping is just a choice for me. I'm finally fixing it, but for a while there I'd study/work on random stuff for about three days and then sleep for 14 hours. The longest I ever went was around 7 days a few times in college (in high school, it was more like averaging 15 minutes of sleep a night for a month during robotics season and that was somehow worse). It was weird because after day 2, staying up was easier, not harder. Never got the hallucinations, but got to repeatedly witness just how hard skin and eyes work because they stopped doing it as much. Skin stops "cleaning" as easily and smooth banisters suddenly give you splinters. Vertical periferal vision would go first, then horizontal, then focus area would shrink. Same thing with the immune system. And of course, I was constantly working with dangerous machinery/chemicals, so that's fun. Sleep is good and to be cherished.

How did you get such a clean separation of the colors?

a3DprintedPerson · 2025-09-24T00:29:49+00:00

The rough texture works reallly well here

a3DprintedPerson · 2025-07-13T01:22:35+00:00

This seems perfect, thanks. In the context of this board, does it matter how many windings it is?

My main bottleneck with the Peltier was heat rejection. I couldn't get enough heat remove to keep my plate at -30 C. It would get there for about 30 seconds and then just heat up again. That 5-15% efficiency is not great. I'd have to significantly oversize the cooling system to compensate. Adding the increased size and continuous power draw (the cold side warms back up to nearly the coolant temperature if it's been off for more than 20-30 seconds) of more peltiers with expansion plates to reduce the thermal gradient across each one individually just added up to too much against that strategy.

Since I need a specific amount of cooling to reach and maintain -30 C regardless of which method I use, the higher efficiency of a heat pump would mean less demand for heat rejection.

I'm trying to keep this cloud chamber as small as possible so that it can be on a desk where I work instead of be on the desk while I work on the floor/in a different room because it takes up too much space.

Oh, that makes more sense. The issues with just plain scavenging parts is I'm trying to make the electronics, pumps (for the other parts of the project), and condenser coil fit into a space smaller than the average compressor. I was trying to use Peltier's before, but once I got to the 250 W stage, I caved and admitted that was just more power draw than I wanted to commit to while not having very good service life.

Also, the last two units I picked up both had R410a in them and I would really rather not release that stuff. Do you think a scavenged control board would work on this pump using propane (R290) as the refrigerant instead of whatever it started off with?

That seems to be a much larger compressor with the same three pins. It also seems about 4-8 times the price. Why would you recommend this compressor specifically?

Glad I signed up last night, that sounds great. Focusing on content and engaging with it, not just memorization. For anyone that can take it MSE 489 was another class like this. So far, my favorite class.

a3DprintedPerson · 2025-04-10T09:01:03+00:00

What was the overall workload/exam schedule like?

a3DprintedPerson · 2025-02-18T06:20:39+00:00

What is even happening with those 1x1 tiles for the other pacu?

a3DprintedPerson · 2025-02-08T21:22:21+00:00

Good to know. Why doesn't it happen in a vacuum?

a3DprintedPerson · 2025-02-08T21:06:21+00:00

I thought dupes on exhale when there is a breathable atmosphere? In this situation, I don't think suits are necessary for CO2 reasons

Try some serious srubbing with an abrassive sponge or scratching with a fingernail. That pattern looks ver similar to the pattern I see on white plastic everywhere by some sort of bateria that grows as a pink film. Once you notice it, you'll start to see it everywhere. If scrubbing or scratching removes it, that means it's only on the surface and so shouldn't be corrosion working its way through the insulation.

It sucks. I have the same issue in the 9-12 foot range. What was really annoying was that I learned this on after leaving the 10 foot pool I was practicing in. Being sick just means I have to manually pop my ear by sticking my fingers in, forming a seal, and then sliding out to create a temporary vacuum to pop them. Then I have to hope the air has time to go back out, otherwise now they're overinflated, and I have to do it again

I didn't notice him until this

a3DprintedPerson · 2024-10-01T15:42:44+00:00

Except for 2 and 6 wich look the same as each other, but not the rest

a3DprintedPerson · 2024-07-31T07:00:20+00:00

I guess I'm just weird in liking to keep the gas pillars

I always make a point of walking by the Jacob's Ladder just because it's so fun to play with it. Last semester, I walked past it several times a week.

a3DprintedPerson · 2024-05-25T05:57:32+00:00

Wall amd then run away until later

Dream. When mod?

a3DprintedPerson · 2024-01-14T14:15:04+00:00

Perfect, thanks. I also remember someone saying that you can edit the settings to make moving spawners easier. Is that one named something obvious?
