hey,

I made a thread back on Jan 1st about wanting to make a slime machine by end of march.
I've gotten as far as a proof of concept model, but it needs a ton of work.

Here's a first run https://umd.net/profile/i/scroggle/section/videos/video/machine-test
It's got a single pump and gunge deposit pipe at the moment but I am thinking to add more dimensions.

The pump can take rocks/dirt up to 1/8 inch so I'm thinking thicker or savory slime shouldn't be a problem.

Anyone whose built this kind of thing and can give advice would be appreciated.

This looks amazing

Update:
Initial post referred to out of date video, here is the latest.

I'm also going to answer all questions related to it here, and then refer PM's back to this thread.

PVC Construction:
I'm using these to build a frame that holds things

Slime Drum Thing:
it's called a conical tank. but i think it was a mistake to get this. There are large drums and trash cans for a fraction of the price at home depot. I could have done something like this https://www.hunker.com/13425631/how-to-put-a-garden-hose-spigot-on-a-five-gallon-pail at the bottom and got the job done cheaper, but i had seen the drum thing and went with what i knew

Pump:
Spending 200 on a pump was kind of annoying to me, but it turns out you need something of this size to move that much fluid. This pump supposedly can handle solids in the fluid so it should be able to handle thick slime, but I've only tested it with the 'gunge' in the one test video (jello powder and water).

The pump also requires you to wire it up yourself. I needed a number of ancillary items just to get it to turn on:

Connections:
I bought things like this
https://www.amazon.com/Beduan-Clamp-Stainless-Sanitary-Fitting/dp/B083GGZQYT
and clamped together with this
https://www.amazon.com/Beduan-Stainless-Single-Homebrew-Ferrule/dp/B07MSFC9S4

basically, there's a system of parts that are clamped together that are used by brewers, chemical plants, ect called "sanitary gauges". I worked with them in a lab in college so i know what they are and apparently amazon sells all this stuff now.
You'll need to get flexible tubing from McMaster as well.


Pulsing:
I used an arduino UNO, coupled with this https://www.amazon.com/dp/B00WV7GMA2 which let me turn the pump on and off from the arduino.

If anyone is trying to seriously trying to replicate anything, let me know and I'll provide more details.
Just know a lot of this is WIP so i might find the pump burns out tomorrow or something.
