DIY 10" sunlight readable plotter

[BellaX]

Hi all,

i populated three pcbs, two of them fully and one partly, this means without video
engine, HDMI switch and LVDS driver to bring up the power supply.

After fixing some wrong wiring and optimizing the switcher feedback loops i got
a stable picture:



This week i made the schematic and pcb design of the keyboard pcb and etched it
at home. This is how the plotter actually looks like:



Basically the buttons and sound output are working. Currently i am writing a script to
detect buttons and pass the right key codes to OpenCPN.

Next step is to bring up the PIC microcontroller that generates the pwm to control the
display brightness and HDMI-source selection.
