Every place I went was system D except one.
Here was my shopping list:
Vice for the drill press, bought it from a guy on the street at a open market.
A flap sanding disc and polishing disc for granite, open street market seller. 2 women with a stand.
Other bits of hardware and materials including half a sheet of steel plate.
4 pounds of chicken feed.
Half pound of sugar
Half pound of raw peanuts
A big scoop of margarine. They were re-packaging it from a 5 gallon restaurant sized bucket and selling it in baggies like scoops of ice cream.
The only thing I could not get from System D were a couple proximity sensors, a couple power switches, and some pneumatic fittings from a regular store.
More info about System D coming in a future post titled: Lessons from the third world.
