Experiments carried out in the past (from 2011) are described hereafter:
"Quoi de neuf" means "What's new"...
For 2015, everything is described below...

No time to do anything about "real electronics".
A few things, anyway:
- I have bought a new RPI 2, installed opencv on it and done a few experiments about line following using Canny and Hough. The idea is to be able to run some benchmark to compare performances of the PI with respect to a Zynq.
- About the Zynq... I have also bought a Zynk board at MyIR. A nice little thingie comes with 1GiO of SDRAM, a Zynq XC7Z020 and many devices (Ethernet, Usb, a buzzer, a CAN network, etc.). The board comes with Ubuntu pre-installed. The idea is to run some hard/soft combination at bare metal level. Hopefully, I have found a nice tutorial here.

- I have started a small experiment with sound synthesis chips. Right now, I have hooked a YM2612 to an Atmega. My objective is to be able to read and play VGM files.
- To familiarize myself with VGM, I am writing a small VGM parser in Python.
- There are quite a large number of sound synthesis chips: SN76482, the Yamaha family (YM2608, YM2612, YM2149, YMF262, etc.), the AY-3-8912, etc. Wikipedia has a very good set of articles about those sound chips.
