Hello! hahaha well, the main reason I want to see this working is generating high voltage, but, It would be so funny watching it catching fire!
Yes, now I understand that the MOSFET must be on the reverse side, drain and source. Gregebert, Am I okay with this quote? *"To see the Booster working, The PIC needs to send and OUTPUT via RC2 (in this example) so, this little current gets to the Gate pin of the MOSFET so it start's going on with the Switching mode (Helped with Q1 BC856), sending current to the inductor L1 which generates picks of high voltage that are then stored on the capacitor and later given to the nixie tube?" * THANKS!
