CEB Press/Manufacturing Instructions/Detroit Fab Lab Solenoid Driver v4

Source File Repository:

All source files are located in this repository: schematics, board layout, netlist, arduino source code, etc.

https://github.com/dwiel/ose-cebpress-controller-board

Goals:


 * Add Left/Right/Up/Down buttons on board
 * Add Left/Right/Up/Down terminal positions for external control
 * Add Left/Right/Up/Down to source code
 * Build schematic and board layout in with KiCAD

Design Rational:


 * Buttons and terminals must all be easy to access
 * Circuit board must be easy to etch by hand
 * Populating and soldering parts of the circuit board should be easy
 * Using more through hole components this time for this reason
 * Circuit board should be small so that they are cheaper and faster to etch/mill

Notes:


 * Does anyone know how much current the solenoids require? We probably don't need such beefy MOSFETs ... (the original MOSFET is rated to 50V,16A)
