Nibble Away

Place a digit from 1-9 in each cell so that there are no repeats in any row, column, or box. Digits separated by a knights move cannot contain the same digit.
A digit on an arrow indicates the value of the binary number read from the next 4 cells seen in the direction of the arrow, when counting odd digits as '1' and even digits as '0', and treating the furthest cell as the lowest bit. For example: if the next four digits seen from an arrow are 8275 then the arrow must contain a 3 (0011).
Lösungscode: Column 7

Hard to wrap my head around, and found myself staring at the harder problems and ignoring the easier ones. But I nibbled away at it and got it done

Very beautiful puzzle, I used to always love the binary arrow constraint :)

Oh yay! I was so hoping that Nibble implied a binary puzzle! Can't wait to try this!

It was so hard to find the way forward but eventually I have cracked it.
