Formula Sheets for some UBC Engineering courses

1 year ago

After the use of a formula sheet for MATH 217 Multivariable and Vector Calculus to help me review and study, I decided to expand this for some other courses. They've helped me throughout the semester as quick references to formulas when I couldn't remember it on the spot.

Not all courses allowing...

Fourier Transform of a Generic Gaussian

2 years ago

The following computation was done out of an exercise from ELEC 221 Signals and Systems. The method does require some trickery to compute, but once it's done, we have a stunning result: the Fourier Transform of a Gaussian is another Gaussian!

Result: The Fourier Transform of the Gaussian \(f(t) =...

Some Information on the BluePill (STM32F103C)

2 years ago

Below are some observations one might encounter when working with the STM32F103C as a micronctoller in conjunction with the Arduino STM32 library. A good secondary source for documentation s Leaflabs Maple.

Some of these details here are specific to a certain STM32F103C model, such as the LE...

A Hackintosh Experience as a Long Time Windows User

2 years ago

One of the things I see many software developers use is a Mac. Even at Microsoft's own Build expo, you can see presenters use macOS to use Microsoft VS Code. This puzzled me a bit, so I did some digging. For the most part, a Macbook is an all-in-one package for a decent laptop that runs on linux. Th...

USB Serial for Blue Pill (STM32) with PlatformIO

2 years ago

The Blue Pill (STM32) can be bought very cheaply on sites like eBay and Aliexpress, but they likely do not come shipped with a USB bootloader. You are then forced to use a USB to Serial/USB to TTL to interface with the BLue Pill, and that can be a nuisance sometimes, especially since you have to cha...
