Pick out a PC board from MadBean, then have him order all the parts himself from SMall Bear. That'll keep him even busier.
MadBean's "Nutrino" Eternity clone is a pretty easy build of an otherwise high-end TS-type pedal.
I just finished a MadBean "Fat Pants" EP-3 style booster. That one's real easy. Sounds great as an on-all-the-time tone-tweaker. Not really enough gain to work as a solo boost.
MadBean rates all their projects by level of difficulty - just look for the "Noob" symbol.
