jupyter notebooks dont work with latest code, coils not in series, spacing between via and track too close

[Rik Starmans]

Jupyter notebooks don't work with latest code
Your code stopped working after commit 7bde6ea .
The changes after commit 7bde6ea , for the led board, make several notebooks fail, as a result it does not work.

coils not in series
In a normal electromagnet all coils are in series. In your boards, the even layers are equal to front copper and
the back layer is equal to the odd layers.
As such your motor, has part of the coils in parallel. This increases current.
Magnetic strength is linear with current. Heat dissipation goes via the square.
As such, your board might not be optimal if heat is the limiting factor.

spacing between VIA and track
Boards are made with track width of 0.127 as prices go up on PCBway below 5 mil.

I also found these holes quite close, i guess current flows here from red to blue and should not continue on red

Still the via is very close to the red, which makes it tricky.

I am very happy with the package. I just point this out to help others.
