This week we are looking info reading sensor data, for example reading distance sensor, light sensor, thermistor… I chose to work with and accelerometer/gyroscope because I find it very useful.

Group Assignment

The page describing the group assignment for this week (probe an input device’s analog levels and digital signals) can e found here.

Arduino code

This website was my starting point when working with Adafruit accelerometer and gyroscope. It contains the pinouts, library installation guide and a very helpful example code.

Group Assignment

The page describing the group assignment for this week (review the safety datasheets, make and compare test casts, compare printing vs machining molds) can be found here.

Introduction

This week we looked at molding (process of creating a hollow cavity that replicates the shape of an object or pattern) and casting (process of pouring a liquid or molten material into a mold cavity to create a solid object with the desired shape). The goal is to make a design, then mill the positive mold out of wax, following a negative mold from silicone and finally cast the desired design from liquid plastic.

This week we were working with a new XIAO board that has a WiFi/Bluetooth dual-mode chip, and therefore is capable of creating and receiving a radio signals.

Group Assignment

The page describing the group assignment for this week (send a message between two projects) can be found here.

New board

Lets see if this new board works with any of the previously made PCB boards, as the new XIAO had the same pin layout as the XIAO RO2040.

This week the task was to create an application that would interact with the board through Wi-Fi. I used the REST API.

Group assignment

The page describing the group assignment for this week (compare as many tool options as possible) can be found here.

The idea

I would like to draw on a PC screen using the accelerometer. So the web interface would be sending request to the XIAO every 200ms, and the response would be JSON style dictionary saying if the sensor is titled (and how much) in an x & y direction.

I chose embroidery for my Wildcard week, not only because it is cool, but also because I can use it for my final project.

I will be working with Bernina 790 Plus.

This is how the machine looks like when I use it for sewing:

We have this lengthy and very informative manual with it, so I started by reading the section of how to change it to the embroidery mode.

To make sure my project won’t suffer from approaching deadlines, I made a schedule for the remaining time left in my FabAcademy which includes all tasks I should still do.

I also made a sketch of how I’m imaging my project will turn out like. This helped me identify all the remaining tasks.

In the system integration week, I aim to make a nice enclosure for my electronics, one where all the PCB boards and electronic components will be securely attached. As Neil mentioned during the Global lecture, I should be able to shake my project without consequences.

Introduction

This week I continued to work on my final project. On this page will further describe the circumstances of my project, and answer some specific questions.

Some questions are answered in the Final project documentations, which can be found here.

What will my project do?

My final project - an Oracle - will be making a positive random prophecy for you, so you can find an encouragement and motivation in hard times.

Future plans

The final project was an opportunity for me to explore my capabilities and learn how to use the machines in the FabLab. I do not see this project being widely available or sold somewhere, but it would make me very happy if this project inspired someone else to make a similar Oracle. I plan to upload the final video on YouTube, and maybe the algorithm will do its job and the right people will find this project.
