## First PCB Design

How do you mean I can’t do make clean, fix bugs, make all ? When software engineers make hardware things can only go wrong; notice the size of the switch and the footprint on the PCB. But apart from that, pretty fly for a software guy.

The PCB design was done with KiCad on Linux (but it is also available for Windows and MacOS).

### RGB LED Display test

First test of a new RGB LED display for a train in Canada. The display has 16 x 144 high power RGB LED’s to make sure it is readable in bright sunlight. The hardware uses a iMX6 CPU and runs a custom Linux OS. Content is send to to display via Ethernet using client specified rail/public transport network protocols. Since it is a multiplex display it is rather difficult to film because the update rate is different from the camera framerate so it looks like it is flickering. [Read More]

## BLS Roll-Out

Roll-Out of a new train with a Passenger Information System partially (OS porting, GUI, and build management) written by me. That includes the LED displays on the outside and the TFT displays on the inside, although the inside TFT displays are not visible on this video.
