PITTSFIELD, Mass. (AP) _ A Pittsfield man whose 2-year-old son said to police ``Big boom, Daddy uh-oh'' after his father accidentally detonated a homemade bomb in his house has been sentenced to two years of probation.

Joseph Capitanio was sentenced earlier this week for what his lawyer described as ``one of the dumbest things he's done.''

The 33-year-old Capitanio pleaded guilty in October to possession of an infernal machine and other offenses.

Authorities say Capitanio tried to build the explosive in March by packing a CO2 canister with gunpowder, but accidently ignited it when he tried to seal it with a blowtorch.

The Berkshire Eagle reports that Capitanio's son was in another room when the blast went off, but wasn't harmed. Capitanio was injured by shrapnel.

His lawyer says Capitanio didn't intend any harm.
