Computing the convection coefficient of a brake disc

I estimated the heat convection coefficient of a Formula SAE car. Let me share what I learned.

Engineering

Estimating the working temperature of a brake disc

I used a lumped-body approach to approximate the properties of a brake disc and simulated its temperature increase after 100 braking maneuvers.

Brake system load distribution study - MATLAB approach

I studied the brake load distribution of a Formula car using a simple Matlab script. Let me show you how I did it.

I'm improving my blog using schema markup

If you are writing how-to posts or guides, you should do this. For any kind of content, really.

Getting the size of a 3D print model from G-code

I wrote a Python script to get the size of a 3D print job from Gcode. Let me show you how it works.

Life

Fail better with an engineering mindset

Failure is often seen as a negative part of life we tend to avoid at all costs. And sometimes we become too good at it. I'll tell you how I learned to embrace it.

How I avoided typing long passwords - Use at your own risk!

I programmed an Arduino Pro Micro to write a long password every time I pressed a button. It helped me save a ton of time and I'm sharing how you can make one yourself - at your own risk!
