My System Specs


I dunno. Maybe the trusty potato cannon would be a better/funner project?

Edit: I tried converting barometric pressure to inches of mercury with negative values. If you'll forgive the pun, it doesn't seem to add up. -0.75 bar = -22.15 inHg ?

Isn't vacuum better expressed as a positive rather than a negative? My brain doesn't want to go there I guess.
