fuel-economy

An iOS app to track your fuel economy.

MPGuino is a great Arduino/AVR based fuel trip computer that calculates mileage by directly reading fuel injector pulses and vehicle speed pulses. Great for pre-OBDII cars, and more accurate than OBDII-based trip computers.

For this group project, we took a look into which characteristics in vehicles drive sales in Norway. We then performed an ETL (extract, transform, load) on the data.

Unit conversion toolbox for DeepSeek Harness (dsh): 20 categories — data transfer rate (Mbps vs MB/s), acceleration (g-force), illumination (lux/foot-candle), power (3 horsepower definitions), force, torque, typography (px/pt/em/rem), fuel economy (mpg ↔ L/100km), data sizes (MB vs MiB) — zero runtime dependencies

A simple calculator, using the 70% rule to help you to decide which fuel is better for your vehicle.

Predicting annual fuel costs and analyzing vehicle efficiency using the 2025 EPA Fuel Economy dataset. Features EDA, inferential statistics, and a 7-model ML benchmark (XGBoost, Random Forest, Decision Tree, Elastic Net, OLS, Quantile Regression, Bayesian Regression) in R to identify key cost drivers like MPG, cylinders, and drivetrain.
