Fab Academy 2022.
We make, modify and share a new variant of the open source machine.
Last weekend, from April 1 to 3, we moved to the Fab Lab in León to carry out our group practice, and manufacture the HILO Spinning Machine.
The machine we decided to make belongs to studio HILO. studio hilo is defined as a Berlin-based studio for textile innovation. We rethink the textile industry by offering open tools, training and consultancy for small-scale textile manufacturing environments. HILO’s mission is to create playgrounds for independent yarn production. The HILO Spinning Machine (and Software) is an open source project by Studio HILO and allows users to produce their own customized yarn.
HILO studio has several open source machines to manufacture, in our case we manufacture the HILO Spinning Machine. The HILO Spinning Machine with its open-source software brings local yarn manufacturing into your workshop. You can choose your raw material, design the yarn properties and produce customized yarns on the spot.

Modifications in the original project
We make, modify and share a new variant of the open source machine.
On Friday we found several pieces of the machine that could be of standard measurements in order to simplify the assembly of the whole, as well as we found that there were a significant number of parts that needed to be purchased, but they were easily replaceable with 3D printed parts, so the machine could be produced more locally.
For all this, the improvements that we will make in the project will be:
- Identify parts that may have standard measurements
- Design new parts to produce them by 3d printing that replace expensive parts
- Design and produce new parts that improve the operation and useful life of the machine

Structure assembly
The first group of pieces that must be assembled are those that form the HILO structure, in this group we standardize the measurement of five profiles at 230 mm, we also design 90º joints, some support pieces for the machine and a hinge for the top all this parts will be made on a 3d printer.

Processing & Arduino
We installed the arduino app to the arduino mega, the original HILO project has a processing interface to control it with your computer, with it you can control the different working methods that the machine has, we made little changes on the processing interface for a better use with the arduino adding some parameters to the original one.
