Welcome to

my personal compound of Digital Signal Processing (DSP) implementations in microcontroller and FPGA architectures. The DSPsandbox project is driven by my passion for inventions, hardware programming and by being a firm supporter of the do-it-yourself approach.

About me

I am Pau (without “L”), a physicist with a passion for digital electronics and hardware programming. I define myself as a very curious and persistent mind, with often more captivating ideas than time for pursuing them. As part of the Quantum Engineering Solutions department of Keysight, I develop firmware for the control of quantum computers and quantum simulators. Simultaneously, I am writing my PhD thesis at the Photonic Institute of Barcelona (ICFO). In my free time I enjoy swimming, doing outdoor sports (mostly hiking and mountain biking) and carpentry.

While as a kid I liked to open and disassemble most of my toys, now I am challenged by designing tailored alternatives to expensive commercial DSP products. Do you have an inspiring hardware programming application in mind? I am always happy to know more about your ideas and discuss about suitable FPGA and microcontroller solutions.
