The design was simplified and made to fit super simple electronics. The ideas was to make a design for a working Neuralizer that could be easily replicated with parts many electronics nerds will find around their house or that can be bought cheaply.
Personally, I used 10W LEDs (12V drop), and the super simple schematics that can be used for such a circuit is attached above. I've also provided a few alternative circuits that can be used if you have other parts than the ones I had. For example, if you want to use a normal LED instead of a 10W LED. Use files from the "Extra Files" folder (which includes STEP files for easy fitting of alternative components), add a 380Ohm resistor for current limiting (shown in schematics), and you're good to go.
The schematics can of course be "mixed and matched" to fit the components you have available. More ideas in this YouTube video:
