Ye, thank god I had basic electrical engineering drilled into my head at an early age, after getting a handle on the different components involved I'm getting pretty comfortable with cobs, my cheap ass just scraped the grinder so I'll leave math for later but the 50~v cobs may be something to look at I don't remember but I'm hoping I saw them for 15, cuz that'd be 280w at 1.4amps for 4 which seems sexy,
about what area does a cob hit? I've been having trouble finding that so I can't really get a feel for what exactly it would cover. ain't smoked since planting ma bebes go grinder/bowl scrape
