Felipe is a digital hardware hobbyist, turned software guy, turned person who keeps a CNC machine in their shed.
He started out as a kid messing around with TTL logic circuits and diode bridges in a farm, circa 2009. Upon realizing everything about hardware was expensive, he made the conscious decision to instead study software and computer science. He first worked in open source software for weather stations (as part of a little known Brazilian group called CCSL-IFRN).
He then had stints in freelance web software development, machine learning, fault analysis, cryptography and is now working developing test methodologies and software for testing novel Wi-Fi HaLow systems.
In 2024 he was bit again by the hardware bug, now with some funds to spend he instantly fell through the deep deep hole of open hardware and is working on his open source/open hardware dream calculator.

Abstract
What happens when a self-proclaimed "software guy" embarks on a journey to produce the best calculator they can conjure?
I would have never imagined it would lead to me building a computer controlled drill in my kitchen and losing my fear of complex electronics. But how did I get there? This talk is about my path from posting "What if I made an HP-42s inspired calculator" on the internet to having a little yellow device in my hands that computes things according to my typed out wishes.
You will learn about designing languages, drawing mock ups, computer aided design, 3D printing, PCB design, CNC operation, laser engraving, and above all: why would anyone want to design a calculator in 2025?
