Overview of parts and approx. costs

Membrane pump (~$160) - (TBD – cheaper solution will be available soon)

Stabilized membrane pump

3D Printed Parts

A: Upper Case (3D Printed)

B: Lower Case(3D Printed)

C: Intake manifold(3D Printed)

D: LED/Sensor holder(3D Printed)

E: LED/Sensor holder(3D Printed)

Print on any 3d printer or send to any service provider. Use black filament / resin. If possible, use flex filament or mix resin with flex resin. 200g Resin / FDM ~ $5-$10
- 3D printing service is more expansive (~$100)

STL for 3D Printing (SLA or FDM) github repository or bcmeter.org)

PCB of bcMeter (Raspberry Pi Hat)

F: We recommend the 5V PCB. Find gerber files for PCB fabrication on github) ~$25

bcMeter SMD PCB for 5V and smaller pumps

bcMeter general purpose PCB for 12V, less accurate but more easy to assemble (THT)

Components to be soldered on the PCB

See Bill of material for links to buy the following:

G: Components from mouser.com or anywhere else (~60)

Filter paper

H: Filter papers – Type TBD, tested with Pall T60A20 – ask local labs for availability
This is crucial, tell us what type you use, send us a sample and we find the correction factor to use. Refer to Correction factors for different filter papers

Basically any filter works, the device just has to be calibrated against it.

Additional material / Tools

I: Additional material:
See Bill of material for links to buy the following:

22-30 AWG Wire to connect the sensor and LED to PCB
Hot Glue - use to seal air leaks around sensor brackets ~$7
Rubber band (SHORE A) for sealing intake ~$11
Silicone hose 5mm inner diameter ~$5
M3 Screws ~$3
M3 threads ~$7
microSD Card (4gb+)~$8
