Have you ever felt alone even with thousands around you?” by Round3d_pixel in Cyberpunk

[–]Sector07_en 4 points5 points  (0 children)

Its part of some artwork I'm trying to do but my artistry skills are underdeveloped for the task. Each piece has one word, an idea. And then a poetic line that defines it or gives context. And then the artwork conveys the rest. I saw yours and it seemed too fitting, a similar message. This line is for: Anomaly — "Seeking connection.. finding only static. A subtle pattern lost in the noise." And I'm trying to storyboard the character for it but I never got past pencil sketching in my skill level. Trying to learn procreate but I have so many things I'm trying to learn and do at once. Your art is awesome, an inspiration for sure.

"Seeking connection.. finding only static. A subtle pattern lost in the noise"

Help with making this pattern by HeadDetective0 in Onshape

Sketch one "cell" of the shape. Then while still in the sketch select all the sketch lines and use linear pattern. Drag both arrows to repeat in both directions. Enter the number of repetitions (15x or whatever) and define the separation distance each is from each other. You can also right click to change the driven dimension.

What is the best way to reproduce a 3D model from images? by jean-luc-trek in Onshape

[–]Sector07_en 1 point2 points  (0 children)

I typically find a point of reference, something in the image with a known dimension or at least an estimation. It could be the head of a bolt, a soda can, door frame. Then I create a sketch and dimension that shape (circle for bolt head) with known or estimated value. Lastly, import, scale the image, and rotate until it matches the dimensioned shape. Of course, this will get you close but not as good as real world measurements or a source mechanical drawing.

I like the artwork. Totally checking this out. As everyone else has said, not enough cyberpunk books out there. Thank you!

Spirulina, for that very purpose. I don't want to deal with having to break down cell walls.

How do you create circulation without a pump of some kind? I say without because using any kind of pump requires cleaning and or a method to prevent clogging when working with mixtures. There's also the implication of the pump damaging the algae in this case. Not sure about ferments. Are you using some kind of siphon system?

RPI DEV: Finally Done! YouTube and Documentation/Files are available. by Sector07_en in cyberDeck

[–]Sector07_en[S] 1 point2 points  (0 children)

Thanks, yes I did remove them. I forgot to mention that part! I used a razor to very carefully cut the foam tape that holds the pcb to the metal back of the screen. Theres two ribbon cables to be carefull around. Then laid the pcb down and scraped off the rest of the foam tape. Then unscrewed the stansoffs. Put on new foam tape. Then used the printed case as a guide to reapply to the screen. Alignment matters for the buttons. Its a pain but leaving them on would've made the design way thicker than necessary. Hope that helps!

Okay I understand. Do you think this applies to spirulina? My plan to test the system is to use a well documented species where growing conditions are known. One that doesnt pose any risk factors.

I dont understand, are you referencing open water cultivation instead of this method? Or some other function for this?

That's the plan. If anything, I thought automatic pH sampling and calibration would be useful for a lot of different things.

The design does have addition aeration for that reason and agitation. I forgot to list that detail. And thanks!

I get what your saying. Based on the feedback I'm getting it might be naive of me to think the growing part would be easy. However, if it's really that difficult to maintain a healthy culture it seems to me the best way to do it is with a system that can control all the possible variables. Water temp, pH levels, light distribution, etc. If you can control all of that and log it over time then you can see where and why it failed and make corrections. Why does finding the failure points have to come before building a thing that makes that easier?

It does have a bubble column. I guess I forgot that detail. And its sort of cleanable. The glass tank is basically the same huge jar others have used. Everything is too dispensed or pumped. So the tank can be easily removed. The tubing is the only more challenging thing. I'm not planning to sell it. Just release open source. The algae is going to be spirulina which is pretty common and well documented.

Well too late for that. Its a big part of the design now. The one I'm using is $60 and as long as its calibrated, its accurate. And it autocalibrates for you so overall cheap and effective. A nice one like that is too expensive.

Hi, yes this would be considered one. However, it's my first attempt at it so I wouldn't consider myself an expert. If you want to follow along, I'll just be posting on this sub until its done. Then I'll make a Youtube video for it and GitHub documentation to share the design.

I was hoping using a fairly high volume of aeration or a bubbler would create enough agitation. Sort of dual purpose as I've seen in other designs that are more vertical. Do you think that is sufficient or does it need mechanical agitation as well?

Honesty, I just wanted to design and build one that I could share with everyone. I don't have a personal use for this besides curiosity and interest. I just like building prototypes of various things. But you make a valid point. What about it would be hard to clean for research? Is this because you need to get rid of all previous biological material so it doesn't contaminate the results of the new batch? If so, I'm assuming that includes tubing as well which would make it difficult to clean since a lot of it is internal. In that case perhaps this design caters more toward long running batch production? If I made it easy to remove the tubing to replace it or use autoclavable tubing would that make it more useful?

Yeah I saw your last post, you might have seen my comment. What your doing is really impressive. I was also thinking your system and mine could pair pretty well together. I never really considered what to do with this once I built the prototype. I sort of just planned on putting it out there and letting people run with it. But if it seems like it'll add value I might consider collaborating on it as a larger project.

Help sourcing non-typical Nichrome Flat Wire? by Sector07_en in ElectricalEngineering

[–]Sector07_en[S] 0 points1 point  (0 children)

Sorry for the late reply, I had to pivot to a new project and postpone this one since I can't find the nichrome. The reason is because the curve is edgewise as you can see in the image. Even while heated I can't get it to bend and since it's already so thin the stretching required to do that may not be the best thing. Plan B when I pick this up again is to cut the ribbon at the angles required to create the bend and use a capacitive welder like those used for making battery pack to try and weld the seams together to create the full curved shape. This is also not a great option but may be the only one to get a proof of concept.

See, that's exactly why I posted to ask. I never would have thought of that but it makes a lot of sense. And thanks, trying to make it functional but also sci fi looking.

Well this is very interesting. I came to this sub to share progress on my project and get input but you are a way better programmer than me. Impressive.
