PCB closeups with the SEM
Using a scanning electron microscope and fancy digital microscope to evaluate jlc tolerances.
TRL calibration and Wilkinson Validation
Characterizing JLC substrates to test out the Wilkinson
Basic Beamforming algorithms
I’m working my way up to designing a 4x4 element phased array antenna at 5.8GHz. The idea is that two of them will be able...
5.8GHz FMCW Radar Design
Since taking electromagnetics, I’ve been looking for an RF engineering project. After reading Henrik’s blog, an FMCW radar seemed like a good one; the board...
Even Cell Discharge via Current Collector DCIR
Most electrical knowledge in the FSAE community is relatively limited, especially in simulation. Although most teams have Ansys sponsorships (which give full access to the...
DC Link Capacitor Sizing for Traction Inverters
One of reasons for writing maple was to get a better idea of how to design custom inverters for the motorsports race car. Since we’re...
Simulation and Torque Optimization of PMSM Motors
I finally got around to hardcore studying motor theory this winter break, and decided to write (partly as an exercise, but mostly because I think...
3-Level Flying Capacitor Multilevel Inverter
Designing a wirelessly-chareable RC Car with an FCML and resonant converter.
Race car Avionics
As you may know, I’m on MIT Motorsports. We build an electric race car to compete in the formula sae electric and hybrid competitions in...
