LED Guitar

Built at PreECESCON 2016 (theme: Computing Everywhere), LED Guitar helps new users learn to play the guitar at their own pace by lighting up notes and chords directly on the fretboard using an RGB LED strip — all controllable via a companion Android app over Bluetooth. Built from scratch in under 48 hours with teammates (Led Strippers).

PDC — Position Defined Controller

Built at PreECESCON, a Panhellenic 48-hour Hackathon (2017 theme: Smart Houses), PDC is an interactive, all-around controller for smart home devices. Using a combination of motion sensing, IR, and Wi-Fi, it lets you control any smart device by pointing and gesturing — built from scratch with teammates (Bashistes) in under 48 hours.

STM32 Heater

This is a Proof-of-Concept (PoC) application of a Heating Element System that is controlled in a closed loop, using a PID controller. To determine the heating element control signal, we first read the current temperature and, based on the error, generate the control signal.
