Doing ULX3ST FPGA board @home part2

Checking if all pins of FPGA are connected.

Sorting parts.
More sorting.
Soldering FTDI.
Soldering capacitors.
Soldering power circuits.
Random soldering
Random soldering.
Almost done.
Near end.
Problem!!!
Chip was placed wrong.
Fixing chip orientation.
I still had problems, and solve it on this pic. R10 needs to be on board!!!
Checking first voltage JP1.
Checking second voltage JP2.
Checking third voltage JP3.
All good, lets put ADC.
Soldering SDRAM.
And it was really late so I did not picture every step. Here is pic of assembled board.
And back picture.

Can wait to try uploading bitstream.
