Thanks Kevin! They did end up being quite long - but all in all, quite inexpensive to produce.
I did! I have two designs - a more traditional boost converter, and a switching supply. Both exist on boards of the same size, so they can be swapped in/out as needed. A while ago I realized that instead of building my power supplies on to the main board, I can produce smaller HVPS boards and mount them on. Has saved me a lot of $ and time.
