Robin Scheibler is an engineer focusing on data and signals. His research interests have taken him from proving theorems to literally jumping in a cold mountain lake to sample its water, checking for the presence of arsenic. When he works on a problem, he wants to take it from the idea all the way to the implementation into a physical prototype. This aspect of his personality has the happy side effect of spawning collaborations across disciplines such as information theory, theoretical computer science, embedded systems, biology, and the hacker community at large.

Since September 2012, he is pursuing a PhD at the Audiovisual Communications Laboratory of Ecole Polytechnique Fédérale de Lausanne (EPFL) under the supervision of Martin Vetterli. He investigates how structural aspects of sound propagation, the echoes in a room for example, can provide more robust and efficient algorithms for problems such as beamforming, direction of arrival, or source separation. In a different line of work, Robin applies techniques from information theory and theoretical computer science to provide low-complexity algorithms for signal processing problems.

He received the B.Sc. and M.Sc. in Communications Systems from EPFL in 2009. Never longer than two years at a time in Lausanne, Robin visited Stockholm as an exchange student, spent a year at NEC Corporation in Tokyo, and wrote his master thesis at IBM Research, Zürich.

He had returned to Tokyo when the Great Tohoku Earthquake and Tsunami of March 2011 struck and crippled the Fukushima Dai-ichi Nuclear power plant. In the wake of the disaster, Robin joined Safecast to develop its first mobile radiation sensor system. The system was ultimately used to provide the most extensive radiation measurement database available today.

He continues to be active in environmental monitoring through the Biodesign for the Real-World project.

Make a custom Pomodoro timer

I have recently been interested in the ATtiny85 microcontroller. Its minimalistic, yet powerful features make it a very attractive platform for simple hacks and gadgets. In addition, I had been interested in learning the technique of charlieplexing, i.e. controlling many LEDs with very few pins. The ATtiny85, with its 5 GPIO pins available by default (sacrificing ISP yields an extra pin, but I didn’t want to go down that road), seemed like the perfect candidate.

Real FFT Algorithms

Practical information on basic algorithms might be sometimes challenging to find. In this article, I break down two fundamental algorithms to compute the discrete Fourier transform (DFT, inverse transform is iDFT) of real-valued data using fast Fourier transform algorithm (FFT/iFFT).

Papercut circuit board

When designing a printed circuit board to fit in a box of a given size, there is always the fear that when the fabbed PCB arrives, it doesn’t fit.
