Step 12: Final Assembly
I noticed that the cap array has a tendency to rotate inside the pvc tube so I glued some locating sections inside to stop it from doing so.
The important thing to remember is to discharge the unit if you want to work on it again, short the neutral grid to the HV side via the 10Meg resistors to avoid stressing any components.
DON'T FORGET to short out the 220v ac input once you have pulled it out of the wall socket, the caps still carry enough of a charge to wake you up rather rudely.
My future TO DO list might include:
- upgrading the HV pins in the full wave version to CF tips
- change the neutral wired grid in the half wave version to proper earth/ground grid, which just means I'll need a 3 core cable for the input instead of the present twin-flex.
The last image is a view of the upgraded CF tip array after a lot of use so its rather dusty in there.
