Hackaday Award 2022: Making Big Box Trash a Wealth for Art Students

How can a big box store blend the perfect shade of English Weswood in front of your eyes? The answer lies in the highly concentrated pigments that come in different sizes up to about five gallons. Now, imagine the amount of watercolor, acrylic, or other type of paint that can be made by simply scraping the walls of an empty 5-gallon tub, knowing that all the usable pigment is being dumped inside.

Not only that [technoplastique] Making watercolors and other paints from these pigments, their main focus is to create an easily-reproducible process so that not only the pigments can be turned into dyes, but also other things like dried turmeric, charcoal or any other possible material.

The process will probably take the form of an open-source three-roller milling machine, commonly used to make paints. Basically you have three rollers that process the pigments and binders and the mixture is run as many times as needed. Although they are fairly simple machines in design, they require precise technical specs to be made to work well.

We can’t wait to see what happens [technoplastique] Comes with use for stainless steel rollers. The rest of the plan involves a raspberry pie pico, a DC motor per roller, a motor shield and a power supply, but the rollers are quite important. If you have any ideas other than steel rolling pins (kitchen type) or pipe couplings (which are too small, anyway), let us know in the comments!
