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 had the happy side effect of spawning very interesting collaborations across disciplines such as information theory, theoretical computer science, embedded systems, biology, and, outside Academia, the hacker community at large.

He is currently pursuing a PhD at the Audiovisual Communications Laboratory of EPFL under the supervision of Martin Vetterli. He investigates how strucutral 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 Ecole Polytechnique Fédérale de Lausanne (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.

After graduation and spending some more time at IBM, he left Switzerland to return to NEC in Tokyo where he worked on speech denoising technology. Three months after he arrived, 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.

Since September 2012, Robin is back in Lausanne and joined the Audiovisual Communications Laboratory, as well as 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.
