Bill of Materials

 

This section will give a list of items that are used in this project with selected links to suppliers. You can download a more detailed Bill of Materials sheet here

Note: Many of the items listed are just examples and you can use your own discretion to substitute parts which are easier or cheaper to obtain. 

Major Components

 

Miniature Diaphragm Pneumatic Pump

Pressure Sensor (x4)

  • Vendor link
  • Data sheet
  • Operation: pressure causes diaphragm to deflect, and deflection is measured by piezoresistor


 

Solenoid Valve (x4)

Manifold

Power MOSFETs: 4 Opto-Isolated Power FET Switches 

  • (This link may break; search for Four Channel 4 Route MOSFET Button Module IRF540 V2.0+ MOSFET Switch Development Board for Arduino via another vendor if link breaks) Vendor link

 

Arduino MEGA

Power Regulator (x2)

Toggle Switch (x6)

For part and vendor information not show on this page refer to the Control Board Bill of Materials excel file. This excel can be downloaded here.

Base

 

These parts simply hold the above components in place. Use a laser cutter (make sure you are trained first!) to cut these pieces out of acrylic sheets. We use 3mm acrylic for all parts except the base board (6mm acrylic). Cut 2 copies of the base board. Download the .dxf files for cutting here.
