Got a small package arrive today, a step up voltage converter.
As mentioned in an earlier post, I need 10V DC to power my MPXM2010GS (power it? I've no idea how to solder the damn thing, it's a SMT design....), so stepping up the Arduino's 5V out to 10 should do the trick.
Missed the part in the link above where it could also be used with miniature wind turbines to recharge batteries. Nice!
Bloody tired today, gonna rest.
