This has been an exciting week for the team! We began the week with improvements to the microcontroller system: it is now able to read in ADC values and perform end-to-end transmission. On the mechanical side of the team, a… Read More

Sensor Test Preparations (Week 20)
This week team FeraFree made more progress towards our sensor testing goals. The electrical side of the team evaluated available literature and determined that our use of breadboards up until now could be a major source of noise for the… Read More
Simpler Grease Modelling (Week 19)
After much consideration, team FeraFree has decided to forgo physical simulation with the wind turbine replica bearing in lieu of simpler fluid calculations. This reflects limitations in budget, time, and a greater emphasis on producing a functional prototype. Consideration was… Read More
Grease Testing Concepts (Week 18)
Team FeraFree has two main sub-groups, one for the mechanical portion of the prototype and another for the electrical and software portion. The mechanical group (consisting of Nick, Eric, and Diana) spent this week generating concepts for the grease testing… Read More
Cleaning Up The Signal (Week 16)
This week team FeraFree continued setting up the TMR sensor and refining the output signal to detect ferrous debris in grease samples (Diana, Max, and Dr. Marte shown working in the image below). We achieved a practical gain in the… Read More
First Steps of Spring (Week 15)
New year, new testing rig! This week team FeraFree hit the ground running by implementing a number of planned upgrades to our sensor testing circuit. Our main focus remains with the tunnelling magnetoresistive (TMR) sensor, which promises a high level… Read More
