Fidget Toy Challenge

For the month of April, Fox Valley Girls Coding Club will be designing their own fidget toys!

Just follow these steps:

  • Open a free account at
  • Maybe take a look at thingiverse to get some inspiration:
  • Decide if you want to incorporate skateboard bearings
    • I have two sizes: 2cm and 4cm in diameter
  • Design you OWN!
    • Start from scratch on Tinkercad
    • or you can download an stl file from Thingiverse and import it to Tinkercad
  • Publish you design on Tinkercad
  • Post a link to your design to this blog post along with the color you would like
  • Robin Prints it and will bring it to the next meeting!!
  • We will post some images when we get them printed

March 17, 2017 – Advanced Mobile

We will meet in the boardroom in 25 N at 5:45 pm on March 17th, 2017.

We will be continuing with MIT App Inventor 2. If you don’t already have an account – go ahead and make one!

If you have an Android phone or tablet (even old ones), please bring them to class. App Inventor will not work with iOS devices – although we will talk about them!

We will continue working on our Wardrobe app! Happy St. Patrick’s Day!

Meeting Announcements & Notes

March 10, 2017 Meeting – Cybersecurity and Mobile Madness with a Purpose

We will meet in the Board Room at 25N at 5:45 pm on March 10, 2017

Special Guest Speaker on Cybersecurity: Tom Wallace of Jellyvision has graciously volunteered to speak to us about Cybersecurity. Please be at the meeting promptly by 5:45 for what will surely be an interesting talk on a topic that is so essential not only to coders and anyone in the tech industries but to all of us who use these cyber devices every day.

Mobile Madness Project: Continue our special Mobile project, developing Iteration One which we started at the last meeting. We will be referring to this document, so you may wish to print it out:  App Inventor Project Iteration One. We will discuss what makes sense to tackle in the next Iteration.

Meeting Announcements & Notes

App Inventor – Project Iteration One

In the last couple of meetings our group has come up with an idea for a new app, done some story-boarding, and walked through design and requirements for Iteration 1. We got started with some of the coding for that Iteration at our last meeting but didn’t have time to fully implement and test it. To get us all “on the same page” here is one solution that provides a working model that we can use. We have replaced the image component with a Canvas component and added the database. This document details how to build it:

App Inventor – Project Iteration 1


The excellent free online course Mobile Computing with App Inventor – CS Principles presented by Trinity College in Hartford Connecticut and taught by Professor Ralph Morelli via edX is phenomenal  at teaching both App Inventor and Computer Science Principles. I learned about storing photos in a list and a database from doing the Slide Show App of Week 2 of the Course. I highly recommend this course!
