Development

OK, here’s a work in progress, I’ll edit this until I think I’ve got it right at which point I’ll delete this paragraph and add a second post to notify anyone watching this thread.

Bill of Materials

CO2 sparging

Electrolysis

Reagents

Future requirements (not used in the above video)

To allow continuous operation (chemostat/turbidostat) once the culture is established:

To monitor colour (absolutely optional, possibly not even useful, watch this space)

Other extras

Tools

  1. I used a Raspberry Pi 4: Raspberry Pi 4 Model B - 8GB RAM but only because my studio setup requires ethernet rather than WiFi ↩︎

  2. Actually mine was modified by @CamDavidsonPilon to fit the Ethernet cable (Cam, is that mod available online? Answer: yes here) ↩︎

  3. Could be improved, I got this as it is also a 90° bend, but mine is uncomfortably stiff to adjust ↩︎

  4. Would we be better off with a pinch valve? Can we produce an open source pinch valve based on a widely available solenoid? If so, could a 5v solenoid suffice? That would mean we don’t need a second power adapter ↩︎

  5. I don’t think I’d recommend the crimp terminal set I bought ↩︎
