Parts List

Most of this was acquired on Amazon but please look elsewhere. We have no love for Amazon but they do speed things up. Ebay is a good place to price compare.

For the more specific parts I list out the description on Amazon. This should get you to the same product on Amazon.

5 x Garosa Peristaltic Liquid Pump High Flow Vacuum Pump Strong Suction Self Priming Peristaltic Pump Fast Loading Pump with 42 Stepper Motor - The 42 refers to the dimensions of the faceplate.

2 x AC to DC Converter, 12 Volt Power Supply AC 110V-220V to DC.

2 x AC cables with bare wire. You need to have a way to deliver the 110 AC to the power supplies. EIther using PC power supply cables that have been cut or a power cable may have come with the AC->DC converter.

2 x OSOYOO 3D Printer Controller Kit Ramps 1.4 + Full Graphic Smart Display Controller + Mega2560 + A4988 Stepper Motor Driver for RepRap (Ramps 1.4 +12864LCD + Mega2560 + A4988Driver) - Any RAMPS 1.4 (and likely other versions) would work. This just happens to be the one our compile of MARLIN works with - so you can just get that from us.

1/4" ID Silicone Tubing, Food Grade 1/4" ID x 3/8" OD 32.8 Feet Length Pure Silicone Hose I'm not entirely sure what length is needed. If you pump into the sink then this will need to be long enough for that. Otherwise the 33 feet should be sufficient.

4 buckets - 2 for input solutions and 1 for the output solution and 1 for the rinsing.

1 larger bucket or trashcan - This is for the rinse water to be pumped from. It should be large enough for 2 extra rinses. If you don't wish to pump directly into the sink, then you will need another trashcan for the salt water.

A gram scale - This is needed for the mixing of the input solutions and weighing ot the ingredients. It can also be used in the calibration stage to measure how much water was pumped (by weight).

2 mini lathe motors with brackets. - Put in link to post

2 paddles to mix and stir. These are found on amazon as paint stirrers. You may even wish to have more than 2 to help dissolve the original ingredients.

Scrap wood. Preferable a 1x4 of length 5-6 feet. Have a saw to cut it.

20 or so woodscrews to attach the 1x4 to itself.

8 m3 x 35mm screws with nuts. These are the nuts we used to mount the lathe motor. Wood screws will not work given the position of the bracket holes are under the lathe motor.

Insulated 2 conductor wire. Connect the lathe motor to RAMPs board. It needs to be sufficient gauge to power the lathe motor. (lookup)

2 empty plastic bottles. The smaller one will be the mixing container and the large one will contain and support the outer one. (see instructions.)

The power extension cables for the stepping motors. Try "tenth of an inch header" / "Molex" / 2.54 mm pin headers.

Headers/pins (not sure what they're called - see picture) They are inserted between 2 female cable ends so they can connect. We were not able to find a M/F cable. 2.54 mm pin header pins will find them.

Some sort of torch or way to heat the bronze sleeve used by the mini-lathe motor.

A sd card for the gcode for the RAMPS controller.

Something to write to the SD card. Most laptops will not have a SDcard slot.

1 wooden dowel - used for clamping the hose to the bottom of the bucket.

2 medium sized clamps - These are used to clamp the dowel to the bucket.

various smaller zipties. You will use these to attach the hose to the wooden dowel.
