Ça me paraît cool ça comme idée !
Unfortunately there is a bug in the hardware that causes it to emit a high pitched whine (https://olimex.wordpress.com/2018/01/19/teres-i-diy-open-source-hardware-modular-hackers-laptop-update/). The bug is fixed in newer versions. Olimex kindly sent me some capacitors that I can solder to the board to fix it but I haven't gotten around to that yet.
PARCE QUE C’EST MON INSTANCE !
