Raza came to SENSORICA in October 2016, to complete his internship for his 3D modeling course. He worked closely with Tibi and Daniel, who provided technical support and integration within the SENSORICA community. Raza's focus was on 3D design for 3D printing, working with two 3D printing technologies, FDM and and DLP. He gained experience while producing a 3D logo for Hopera, a local beer brewer.
Ethienne, student at Mcgill in Mechanical Engineering, started a 3 months internship with a very serious mission: help strengthen SENSORICA's foundation for its next growth phase. Ethienne is nor coordinating and facilitating different important initiatives that are designed to bring in revenue in the short-term and to increase SENSORICA's capacity:
Rodrigo is now forced to split his time between his involvement in SENSORICA and another internship he took with another company, as part of his study program here in Canada (he a foreign student is from Brasil). That means that in the following months he will spend most of his time with this company. You can see his with us in his R&D report.
Rodrigo will now have the chance to compare the open value network environment with the corporate environment. We're very interested to get his impression after a few months of experience.
manual for the REX C100 PID temperature controller, which will be used to set up the temperature profiles around the PMMA fiber. See Joel's main document for this project.
The next step is to build holders for the fiber, a mechanism to put the fiber under tension, and a switching mechanism to start heating and to stop heating when the fiber is pulled to a given length. Tibi supervised the work, Jonathan was informed about the electronics needed.
Enrique used the setup made by Tibi to characterize and optimize the tape transducer and recorded the first comprehensive data.
The main goal of this experiment was to find the optimal size of the gap (distance between the mirror and the fibers).
The one in 3 out prototype with round glass fiber tip was used. The setup consisted of a green laser coupled to the 125/62.5 MM glass fiber (the in fiber) using a lens. The fiber was hold in place using the reusable ST connector. The one in 3 out prototype (fiber assembly) was prepared by Tibi before the experiment: PMMA fibers were polished and the glass fiber tip was cleaned with alcohol. The tip of the fiber on the side of laser was freshly cleaved.
Setup used during this experiment
Preliminary data obtained
We are looking for a linear relation between angle (mirror tilt) and gap size. The preliminary data shows that being too far from, or too close to the mirror is not good. There is a sweet spot somewhere in the middle. Open the spreadsheet used for characterization and optimization of the tape transducer. Next week we'll continue exploring this same prototype and evaluate its sensitivity. Tibi needs to modify the LabView program in order to allow faster acquisition and better statistics.
