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 recommend using the 5V PCB. The 12V is meant to be soldered by absolute beginners but is less accurate. the 5V pcb is more advanced but harder to assemble.

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

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

Bill of Material for general purpose PCB (THT components & 12V DC Barrel Jack) (G)

bcMeter general purpose PCB for 12V and large pumps bcMeter general purpose PCB for 12V and large pumps. We recommend using the 5V PCB. The 12V pcb is meant to be soldered by absolute beginners but is less accurate. the 5V pcb is more advanced but harder to assemble.

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!
