Overview of parts

Overview.jpg
Stabilized membrane pump


Mandatory

1. You need to have a Raspberry Pi Zero W (the W is for "Wireless Lan", there is also a non-W edition).
2. You need a microSD-Card to copy the Image to
3. You need a Power Supply or Battery delivering 5V/2A

Membrane Pump

It is necessary to use an air pump which is stabilized and has a known airflow or use an airflow meter. We tested with Thomas 1410V (12V - ~300€) or 2002 (3.3V - ~150€) Diaphragm Pumps.
The airflow is mandatory for correct calculation and has to be adjusted in the python script - we're happy to help you out here, just contact us.

Download 3D Printable files (A-E)

STL for 3D Printing (SLA or FDM) github repository - printing material ~10€

Bcmeter-general-purpose-case.jpg


A-E:
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)

Download PCB / Gerber Files for bcMeter 12V or 5V (F)

We have a small stock of PCBs available, just contact us, if interested.

(find gerber files for PCB fabrication on bcmeter.org) ~$25

Filter Paper (H)

Pallflex T60A20 Filter Paper was used during developement and is sadly discontinued. We have a small stock of T60A20 left, so we may send you some material.

We're testing the better available https://www.amazon.com/7194-Non-Heat-Pallflex-Tissuquartz-Laboratory/dp/B0731SG18R.
Or you may send us a sample of your filter paper and we happily calibrate bcMeter with it!
