This week we milled, stuffed and programmed a FabISP in-circuit programmer. This involved first milling the board on the Modela, then stuffing it with components and finally programming the board.
Materials: PCB stock, electronics components
Tools: Modela MDX-20, soldering tools
Software: FabISP firmware, MDX-20 fab module
Year: 2014
The finished board.
Milling the board from the stock. The fab module considers the origin (X,Y,Z) to be wherever the tool is when the tool path is sent.
The milled board, held in a clamp for surface-mount soldering.
A parts list was written out and the required components were collects and attached with tape.
Surface mount soldering was a new experience, and required much more time and trials than conventional soldering.
The finished board, with the FabISP successfully loaded on the first try.
