20180310 Workshop spectrophotometer

The goal of this workshop is to present our experience to go quickly from a prototype to a small production in China (20 pieces) of a spectrophotometer.

This spectrophotometer is open-source and you may check our github project.

During this day you will learn the various steps, you will solder part of the spectrophotometer, you will use it and see some possible applications and at the end of the day you will leave with it.

The following topics will be presented:

• What is a spectrophotometer and an Arduino
• How to create your own PCB that is Arduino compatible (basic usage of Eagle)
• Soldering the non SMD components
• How to create a case using either FreeCAD or OpenSCAD
• Multithread programming on an Arduino
• Beer-Lambert law : checking the amount of E131 (Patent Blue V) in Haribo Smurfs Candies.
