# Tutorials & recipes - [Making biomaterials](https://labpastoe.gitbook.io/lab-pastoe/tutorials/bioplastics.md) - [Gelatine bioplastics](https://labpastoe.gitbook.io/lab-pastoe/tutorials/bioplastics/gelatine-bioplastics.md): Gelatine is made from collagen present in animal parts and comes in jelly, sheet or powder. It is a spiral waste product from the meat industry, being repurposed for uses outside of that industry. - [Agar bioplastics](https://labpastoe.gitbook.io/lab-pastoe/tutorials/bioplastics/agar-bioplastics.md): Agar is a substance obtained from red algae. Agar bioplastic is made by mixing water, glycerine and agar powder. Together they form a foil-like plastic substitute that is flexible, but not elastic. - [Starch bioplastics](https://labpastoe.gitbook.io/lab-pastoe/tutorials/bioplastics/starch.md): Making plastics from starch (e.g. potato, corn, tapioca) is popular because of the readily available, cheap materials and clear thin film result, but it can be a slightly tricky process. - [Alginate bioplastics](https://labpastoe.gitbook.io/lab-pastoe/tutorials/bioplastics/alginate-bioplastic.md): Sodium Alginate is extracted from brown algae. Alginate bioplastics are made by combining sodium alginate, glycerine and water with the curing agent calcium chloride, and are heat/water resistant! - [Flower & plant paper](https://labpastoe.gitbook.io/lab-pastoe/tutorials/bioplastics/withered-flower-paper.md): Using the pounding or blending method, cellulose and fibres of local or withered plants and flowers and/or paper waste can be transformed into colourful paper-like materials. - [Fruit waste materials](https://labpastoe.gitbook.io/lab-pastoe/tutorials/bioplastics/fruit-waste-leathers.md): The biopolymers in fruit waste can be used to create flexible, translucent, leather-like materials. Below two mango recipies, one including starch. Try variations using overripe pear, fig etcetera. - [Many more resources!](https://labpastoe.gitbook.io/lab-pastoe/tutorials/bioplastics/more-recipes.md): Below we listed some useful resources to further explore research and recipes on bio-based materials. Feel free to share any good additions to this list by sending an email to labpastoe@hku.nl. - [Growing biomaterials](https://labpastoe.gitbook.io/lab-pastoe/tutorials/growing_materials.md): In this section you will find recipies and links for growing your own kombucha scoby, mycelium cultures and alum crystals in a non-biolab environment, such as Lab Pastoe, or your own home. - [Kombucha materials](https://labpastoe.gitbook.io/lab-pastoe/tutorials/growing_materials/kombucha-materials.md): Growing a cellulose pellicle from a living microbial culture, using the Acetobacter bacteria found in a fermented tea drink called kombucha. Kombucha material can be paper or leather-like and molded. - [Mycelium materials](https://labpastoe.gitbook.io/lab-pastoe/tutorials/growing_materials/mycelium.md): Mycelium is the root-like vegetative network of fungi. Mycelium releases enzymes to be able to digest the organic substrate it grows on, fusing the organic material together like a natural binder. - [Growing crystals](https://labpastoe.gitbook.io/lab-pastoe/tutorials/growing_materials/alum-crystals.md): Crystals have a magical feel although they are the result of a straightforward process by which the atoms or molecules in a solution are highly organized into a structure known as a crystal. - [Designing interactivity](https://labpastoe.gitbook.io/lab-pastoe/tutorials/arduino-sensors-and-actuators.md): Sensors and actuators are devices that enable interaction with the physical world in your art projects. The Arduino platform allows you to program this interaction to your liking. - [Biodata sensors](https://labpastoe.gitbook.io/lab-pastoe/tutorials/arduino-sensors-and-actuators/biodata-sensors.md): On this page we feature our selection of bio data sensors, such as the pulse sensor, body temperature sensor, muscle sensor and capacitive touch sensor. - [Lilypad sewable electronics](https://labpastoe.gitbook.io/lab-pastoe/tutorials/arduino-sensors-and-actuators/lilypad-sewable-electronics.md): ~ coming soon ~ - [Bare Conductive Touch Board](https://labpastoe.gitbook.io/lab-pastoe/tutorials/arduino-sensors-and-actuators/bare-conductive-touch-board.md): ~ coming soon ~ - [RISO printing](https://labpastoe.gitbook.io/lab-pastoe/tutorials/riso-printing.md): ~ Coming soon! ~ - [Screen printing](https://labpastoe.gitbook.io/lab-pastoe/tutorials/screenprinting.md): Lab has two Mekanika screen printing sets for max. A3-sized prints on textile, paper, cardboard and thin sheets of wood, metal, acryllic etc. We hold several colors of textile paint and puff paste. - [3D scanning](https://labpastoe.gitbook.io/lab-pastoe/tutorials/3d-scanning.md): Lab has several options for creating 3D models from your artwork or from other objects that you would like to either 3D print, or bring to life in a virtual reality or augmented reality environment. - [Handheld 3D scanner](https://labpastoe.gitbook.io/lab-pastoe/tutorials/3d-scanning/handheld-3d-scanner.md): The Einscan Pro 2X Plus is a light and easy to use handheld scanner, that creates qualitative models for 3D printing or use in VR/AR applications. - [Meshroom photogrammetry](https://labpastoe.gitbook.io/lab-pastoe/tutorials/3d-scanning/meshroom-photogrammetry.md): Meshroom by Activision converts a series of photographs to a textured 3D model that you can use to 3D print or integrate in a VR environment, such as Mozilla Hubs, or AR such as Adobe Aero. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
