== Mandatory ==
== Mandatory ==
1. You need to have a Raspberry Pi Zero W (the W is for "Wireless Lan", there is also a non-W edition). <br/>
0. bcMeter Pi Hat (order it prepopulated (~95€) or build your own by producing the PCB and assembling the components (~5€ without componentes each for 10+ orders on jlcpcb or similar)) <br />
2. You need a microSD-Card to copy the Image to<br/>
1. Raspberry Pi 3A or Zero 2 W (~35€)<br/>
3. You need a Power Supply or Battery delivering 5V/2A<br/>
2. MicroSD Card(~10€)<br/>
3. Power Supply 5.25V/2A (~15€)<br/>
4. Air Pump (~10-200€)


== Membrane Pump ==
===== I always have a stock of populated PCBs available, just [https://bcmeter.org/#contact contact] me, if interested. =====
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.<br>
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) ==
== Print the Case ==


STL for 3D Printing (SLA or FDM) [https://github.com/bcmeter/bcmeter/tree/main/stl github repository]  - printing material ~10€<br>
STL for 3D Printing (SLA or FDM) [https://github.com/bcmeter/bcmeter/tree/main/stl github repository]  - printing material ~10€<br>
<br>Use black filament / resin. FDM is prone to leakage if not properly set up. If possible, mix resin with flex resin.<br>


[[File:Bcmeter-general-purpose-case.jpg|500px|left]]<br clear=all>
I'm using Elegoo Jupiter, Saturn and Anycubic Mono M5 - if you have any questions, let me know!
A-E:
<br>''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<br> - 3D printing service is more expansive (~$100)''<br>


== Download PCB / Gerber Files for bcMeter 12V or 5V (F) ==  
== Filter Paper (H) ==
===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.===
We're using AE33 filter Paper with bcMeter. You can use any filter which scattering factor is know. <br>
You may send us a sample of your filter paper and we happily calibrate bcMeter with it!<br>
We can also provide you with a small amount of filter paper to get started.  


(find gerber files for PCB fabrication on [https://github.com/bcmeter/bcmeter/tree/main/gerbers bcmeter.org]) ~$25 <br>
===== We have a small stock of PCBs available, just [https://bcmeter.org/#contact contact] us, if interested. =====

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

Overview of parts

BcMeter parts.jpg



Mandatory

0. bcMeter Pi Hat (order it prepopulated (~95€) or build your own by producing the PCB and assembling the components (~5€ without componentes each for 10+ orders on jlcpcb or similar))
1. Raspberry Pi 3A or Zero 2 W (~35€)
2. MicroSD Card(~10€)
3. Power Supply 5.25V/2A (~15€)
4. Air Pump (~10-200€)

I always have a stock of populated PCBs available, just contact me, if interested.

Print the Case

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

Use black filament / resin. FDM is prone to leakage if not properly set up. If possible, mix resin with flex resin.

I'm using Elegoo Jupiter, Saturn and Anycubic Mono M5 - if you have any questions, let me know!

Filter Paper (H)

We're using AE33 filter Paper with bcMeter. You can use any filter which scattering factor is know.
You may send us a sample of your filter paper and we happily calibrate bcMeter with it!
We can also provide you with a small amount of filter paper to get started.
