Conversion of RX200 to DNA200 and replacement of 510 connector

Shortly after this RX200 mod, I ended up buying a a Wismec DNA200. Well, after almost a year with it, the 510 connector stopped being spring loaded and stayed stuck in the down position, which played havoc with resistance. Being the intrepid modder I am, I decided to use my RX200 spare parts and the lessons learned from this project.

Happily, I didn't need to rewire as the wiring is (mostly) ok - the important power-carrying wires are large enough gauge. So I took the black middle part of the RX200 that I had already modded, the face place, battery sled and battery cover from the DNA 200 in gunmetal gray and got to work.

I took the base of an old 22mm atomizer and drilled it out to 10mm so it can fit a FDV v4 510 and raise it high enough so that it doesn't impinge against the PCB. I then fixed the 510 in with two nuts, one to the top part of the mount and the other between the mount/510 and the case. This left enough space to raise the 510 sufficiently.

Then I had to file away the top of the battery sled slightly, although not nearly as much as the RX200, so the battery sled is still intact. Everything fits in - just. There's not a millimeter to spare and the ground and positive wires need to be placed very carefully so as to allow the 510 connector positive pin to move, as the battery sled exerts pressure against the wires and also to allow the board ground to be connected to the battery negative terminal. In the process I also fixed a stray wire from the bottom board + out that was about 1mm away from the case, a short waiting to happen.

So without further ado, I'm pleased to present my bastard child of a RX200 and DNA200 with a FDV v4 510 connector.
