started work on a solar powered video synth for the solar challenge. I'm using DueVGA library, but also contemplating a more analog solution as detailed in this post, or using the esp32 and this library (which will probably have lower energy requirements).

The Due pulls a steady 165mA while running animated visuals (below), though randomly I did notice it dip down to ~120mA. The bench power supply showed 320mA though, I'm not sure why.

headers straight into the vga cable. later soldered a connection but it didn't work, multiple possible reasons to be explored later.

all wired up
lots of resisters
