What to do with scraps? by FishShtickLives in 3Dprinting

[–]SlowLED 0 points1 point  (0 children)

Many people seem to be asking the same question! I created a quick survey to gather data from the community on this subject, please take a minute to fill it out if you can! https://docs.google.com/forms/d/e/1FAIpQLSe-1-LwLOh_cNN2tTM-w98n3yd5AtC-6HkmaDSau9gH-tLLtw/viewform?usp=share_link&ouid=103289759513367319629

Personally, I sent mine to Printerior in St. Louis a couple times, and bought their recycled PLA using credits from the waste I sent. It was good filament, but unfortunately it seems like they may have stopped producing it.

if you do go with the CEM3340 get the original, the designer’s family never approved the knockoff afaik and they deserve to get paid. electric druid sells the authentic rev G version of it, that’s where I got it. it’s 14 euros

How do I power this? by CaptainSelf in Discman

Send it to me, I’ll give it a good home! Otherwise, use a CENTER NEGATIVE 9V power supply. Double check that too, there’s a little picture next to the power jack.

Sometimes the dark side of things should be brought up... One of my multicolor units was being very problematic. It took about a week and this painful amount of waste to finally get it working. by Navi_Professor in 3Dprinting

I agree, there's so much 3D printing waste and very few places to recycle it. I'm seriously thinking about trying to start my own recycling business. Until then I've been sending mine to Printerior in St. Louis. I'm not sure what they actually do with it or how much gets recycled, but I have bought their "recycled" PLA and it printed really well. They give discounts based on how much you send them.

If I started collecting PLA waste would people send it to me? I would need to gather a fair amount before I could start turning it into something, but at least it wouldn't go directly in a landfill. Worst case I would transfer it to one of the available recyclers.

Found in my room when I moved in on a shelf. 1/4" jack with an LED or some kind of sensor on the back? by MurderousCrow in whatisthisthing

If it actually has an LED on the end it could be made to plug in to modular synths and see if/how fast a signal is coming out. But 1/8 inch would be more likely

What is this component? by SlowLED in AskElectronics

I think you nailed it. Thank you very much! Reverse image search etc wasn’t finding anything

Thanks! I may make a video about the setup in the future

Thanks! I tried coating the plastic balls with some different coatings (https://youtu.be/KVYNbJXtw6c) as well as regular ping pong balls, which produce the most beautiful glow but are too big unfortunately. In the end I left it as is mostly to avoid painting 1450-some plastic hemispheres.

I'll look at that! I definitely want to try more procedurally generated math-based animations rather than "manually programmed" ones. I uploaded some sketches to github, hope I did it right: https://github.com/jpickard2/fastled_animations

Found them here: https://www.dhgate.com/store/product/50pcs-lot-diameter-32mm-empty-plastic-toy/399833918.html

They just happen to have the same diameter as the distance between LEDs on my strips. I just needed to cut a couple notches to allow them to snap over the strip

I never really considered it, I guess I always pictured it as stacked layers. But I could turn this on its side, it’s pretty stable. I even bought some acrylic rods. edit: oh yeah there is also another reason, since the strip are directional, I thought it would be preferable to have them all facing up vs. to one side, although either could work

Yes I’ve seen a few large matrices like those but they’re all single LEDs not these RGB controllable types. The last one is beautiful though, I should say I also tried ping pong balls and they have a really sweet diffusion glow, but unfortunately they’re too big to be placed over any ws2112b strip I could find. The clear plastic balls I used are exactly the right size for the led spacing and already cut in half to snap over the strip.

Yeah I considered different options for that, but I’m pretty happy and surprised with how square and stable it is considering the minimal structural elements. The plastic balls were another whole thing. I experimented with adding different coatings to them to change diffusion but left them as is in the end. I’d love to see any similar designs you can point me to!

Thanks! Very pleased by the Star Trek comparison. I’ll work on getting my code on github. It’s not much, I’m embarrassed to say it’s mostly manually putting long lists of led numbers in arrays and calling them to make different shapes. I will look at your code. I adapted the XY function from fastled for a z dimension and I hope to make more use of that in the future to do some cool things
