A modified optional Greinacher doubler. To build, needs 4 SB540 (or similar) diodes, 2 1000uF x 16V caps, 1 10k-22k uF x 16V cap, optional 3.5mm terminal block, and an optional jumper (you want the jumper, but it’s optional in case you know better or want to play games switching it on and off).

Big cap solders on to the end, use epoxy to prevent flex, and jumper activates doubler. Pictures
